Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial tissue inflammation, substantially impacting the quality of life of patients. The interaction between L-selectin and its glycoprotein ligands modified with 6-sulfo sialyl Lewis x (6-sulfo sLex) is known to mediate lymphocyte homing to initiate immune responses. Thus, this process could be a potential therapeutic target for RA. Herein, we explored the preventive effects of an anti-6-sulfo sLex monoclonal antibody (mAb), SF1, on collagen-induced arthritis (CIA) in DBA/1 mice. Mice were administered SF1 from day 21 postfirst immunization with type II collagen (CII), and the effects of SF1 on both clinical and histopathological disease progression evoked by the second immunization were examined. SF1 significantly suppressed clinical features and histological levels associated with arthritis severity. Enzyme-linked immunosorbent assay consistently indicated that SF1 inhibited the production of CII-specific IgG2a. Based on the reverse transcription-quantitative PCR analysis, SF1 suppressed the expression of interferon-γ, a T helper 1 cytokine, as well as that of inflammatory cytokines, including tumor necrosis factor-α and interleukin-1β, in draining lymph nodes. Collectively, these results indicate that SF1, an anti-sulfated glycan mAb, could be beneficial in preventing CIA in mice and may afford as a novel agent to treat RA.

Abstract
PURPOSE Sepsis in critically ill patients with injury bears a high morbidity and mortality. Extensive phenotypic monitoring of leucocyte subsets in critically ill patients at ICU admission and during sepsis development is still scarce. The main objective of this study was to identify early changes in leukocyte phenotype which would correlate with later development of sepsis. METHODS Patients who were admitted in a tertiary ICU for organ support after severe injury (elective cardiac surgery, trauma, necessity of prolonged ventilation or stroke) were sampled on admission (T1) and 48-72 h later (T2) for phenotyping of leukocyte subsets by flow cytometry and cytokines measurements. Those who developed secondary sepsis or septic shock were sampled again on the day of sepsis diagnosis (Tx). RESULTS Ninety-nine patients were included in the final analysis. Nineteen (19.2%) patients developed secondary sepsis or septic shock. They presented significantly higher absolute monocyte counts and CRP at T1 compared to non-septic patients (1030/µl versus 550/µl, p = 0.013 and 5.1 mg/ml versus 2.5 mg/ml, p = 0.046, respectively). They also presented elevated levels of monocytes with low expression of L-selectin (CD62Lneg monocytes) (OR[95%CI] 4.5 (1.4-14.5), p = 0.01) and higher SOFA score (p < 0.0001) at T1 and low mHLA-DR at T2 (OR[95%CI] 0.003 (0.00-0.17), p = 0.049). Stepwise logistic regression analysis showed that both monocyte markers and high SOFA score (> 8) were independently associated with nosocomial sepsis occurrence. No other leucocyte count or surface marker nor any cytokine measurement correlated with sepsis occurrence. CONCLUSION Monocyte counts and change of phenotype are associated with secondary sepsis occurrence in critically ill patients with injury.

Abstract
Objective There is an urgent need for novel biomarkers in lupus nephritis (LN). We report a non-invasive urinary biomarker, L-selectin, in two independent multi-ethnic cohorts. Methods uL-selectin was tested cross-sectionally in a Chinese cohort (n=255) and a US cohort (n=219) of SLE patients and controls using ELISA. A longitudinal cohort includes 20 active Chinese LN patients. Results uL-selectin was significantly increased in active LN patients compared to active non-renal SLE, inactive LN, inactive non-renal SLE, chronic kidney disease patients, and healthy controls. uL-selectin positively correlated with global and renal disease activities as well as histological activity index and chronicity index (CI). Low uL-selectin was an independent predictor for high CI. During follow-up, uL-selectin levels decreased significantly in the complete renal remission group. Conclusion uL-selectin is a novel biomarker of disease activity and renal histopathology in LN across multiple ethnicities. It also reflects treatment response in LN patients during follow up.

Abstract
Chimeric antigen receptor (CAR)-expressing T cells are a complex and heterogeneous gene therapy product with variable phenotype compositions. A higher proportion of less differentiated CAR T cells is usually associated with improved antitumoral function and persistence. We describe in this study a novel receptor-targeted lentiviral vector (LV) named 62L-LV that preferentially transduces less differentiated T cells marked by the L-selectin receptor CD62L, with transduction rates of up to 70% of CD4+ and 50% of CD8+ primary T cells. Remarkably, higher amounts of less differentiated T cells are transduced and preserved upon long-term cultivation using 62L-LV compared to VSV-LV. Interestingly, shed CD62L neither altered the binding of 62L-LV particles to T cells nor impacted their transduction. The incubation of 2 days of activated T lymphocytes with 62L-LV or VSV-LV for only 24 hours was sufficient to generate CAR T cells that controlled tumor growth in a leukemia tumor mouse model. The data proved that potent CAR T cells can be generated by short-term ex vivo exposure of primary cells to LVs. As a first vector type that preferentially transduces less differentiated T lymphocytes, 62L-LV has the potential to circumvent cumbersome selections of T cell subtypes and offers substantial shortening of the CAR T cell manufacturing process.

Abstract
OBJECTIVES A number of reports on the role of selectin in the process of carcinogenesis, at the stage of proliferation and metastasis, have been available. The aim of the study was to analyze (s)P- and (s)L-selectin serum concentrations in women with EC and to compare these concentrations to clinical/pathological parameters and disease progression using surgical-pathological staging data. MATERIAL AND METHODS A total of 46 patients with EC and 50 healthy controls were included in the study. Serum concentrations of sL- and sP-selectins were measured in all participants. The oncologic protocol was implemented in all women from the study group. RESULTS Significantly higher serum concentrations were found in EC women as compared to controls. No statistically significant differences were found between the concentrations of the soluble forms of selectins and the following parameters: histologic type of EC, histologic tumor differentiation, depth of myometrial infiltration, cervical involvement, distant metastases, vascular space invasion, and disease advancement. Slightly higher (s)P-selectin concentrations were observed in serous carcinoma, in women with cervical involvement, in the sera of women with vascular space invasion and with advanced stages of the disease. Slightly higher mean (s)P-selectin concentrations correlated with lower differentiation of the tumor. Slightly higher mean (s)P-selectin concentration was detected in the sera of women with lymph node metastases and with the serosal and/or adnexal involvement. The results were statistically insignificant, but they almost reached statistical significance. CONCLUSIONS L- and P-selectins play a role in the biology of EC. The absence of an unambiguous relationship between differences in (s)L- and (s)P-selectin levels and disease advancement suggests that they do not play a vital role in tumor progression in endometrial cancer.

Abstract
Positive human papillomavirus (HPV+) head and neck squamous cell carcinoma (HNSCC) presents a higher risk of lymph node metastasis and poor prognosis. Here, advanced microarray analysis of clinically collected HNSCC tissues revealed significant upregulation of the lncRNA SELL in HPV+ HNSCC, and its overexpression was obviously associated with lymph node metastasis. The lncRNA SELL could function as a promigratory and proinvasive mediator as well as an inducer of M1-like tumour-associated macrophages (TAM) by increasing the level of L-selectin. Furthermore, fucoidan, as an L-selectin inhibitor, obviously weakened the formation of tongue lesions induced by 4-Nitroquinoline N-oxide (4-NQO) in HPV16 E6/E7 transgenic mice. This result drove us to synchronously develop a nanodelivery platform to verify fucoidan-mediated anti-growth and anti-metastasis effects. This work highlighted the important influence of the lncRNA SELL/L-selectin on promoting HPV+ HNSCC progression and proposed a potential fucoidan-mediated therapeutic strategy. STATEMENT OF SIGNIFICANCE: Head and neck squamous cell carcinoma (HNSCC) patients with human papillomavirus (HPV) involvement present a greater risk of lymph node metastasis than HPV negative HNSCC patients. However, treatment protocols, including surgery and platinum-based chemo- and radiotherapy, have not improved the 5-year overall survival due to the high tendency of lymphatic metastasis. Here, microarray of clinical HNSCC samples confirms the oncogenic significance of lncRNA SELL, which acts as an M1-like TAM inducer and promotes tumorigenesis by upregulating L-selectin. Fucoidan, as an L-selectin inhibitor, suppresses tongue lesions in transgenic mice, and a fucoidan-mediated nanodelivery platform inhibits HPV+ HNSCC growth. The present study highlights lncRNA SELL/L-selectin on promoting HPV+ HNSCC progression and proposes a potential fucoidan-mediated therapeutic.

Abstract
Inflammation induced by autoreactive CD4+ T lymphocytes is a major factor in the pathogenesis of multiple sclerosis (MS). Immunosuppressive drugs, such as FTY720, are subsequently developed to prevent the migration of CD4+ T lymphocytes to the central nervous system (CNS). However, these immunosuppressive drugs have limited accumulation in lymph nodes (LNs), resulting in poor efficacy. Here, this work develops a nanoplatform for delivering immunosuppressive drugs to LNs for durable MS treatment. Human CD47 peptide and L-selectin targeting aptamer are modified on the nanoparticles encapsulated with FTY720 (clnFTY) for self-passivation and the targeting of L-selectin on lymphocytes, a homing receptor for T-cells entering LNs. Using this natural process, clnFTY nanoparticles efficiently deliver FTY720 to LNs and delay disease progression in experimental autoimmune encephalomyelitis (EAE) mice following a single dose treatment over a 42-day observational period. Considering the daily dosing requirement of FTY720, this strategy greatly improves its therapeutic efficiency. The ability of clnFTY nanoparticles to target lymphocytes, reduce sphingosine-1-phosphate receptor 1 (S1PR1) expression, and suppress inflammatory cytokines release are demonstrated in clinical blood samples from MS patients. Taken together, this study demonstrates that targeted LNs delivery may greatly extend the treatment cycle of immunosuppressive drugs for durable MS treatment.

Abstract
Background & objectives To examine β-D-mannuronic acid (M2000) effects on L-selectin shedding and leucocyte function-associated antigen-1 (LFA-1) expression as mechanisms of action of this drug in patients with ankylosing spondylitis (AS). Methods To investigate the molecular consequences of β-D-mannuronic acid on L-selectin shedding, flow cytometry method was used. Furthermore, the effect of it on LFA-1 gene expression was analyzed by using quantitative real time (qRT)-PCR technique. Results The LFA-1 expression in patients with AS was higher than controls (P=0.046). The LFA-1 expression after 12 wk therapy with β-D-mannuronic acid was meaningfully decreased (P=0.01). After 12 wk treatment with β-D-mannuronic acid, the frequency of CD62L-expressing CD4+ T cells in patients with AS, was not considerably altered, compared to the patients before therapy (P=0.5). Furthermore, after 12 wk therapy with β-D-mannuronic acid, L-selectin expression levels on CD4+ T-cells in patients with AS, were not remarkably changed, compared to the expression levels of these in patients before treatment (P=0.2). Interpretation & conclusions The results of this study for the first time showed that β-D-mannuronic acid can affect events of adhesion cascade in patients with AS. Moreover, β-D-mannuronic acid presented as an acceptable benefit to AS patients and could aid in the process of disease management.

Abstract
Neutrophil recruitment to the inflamed endothelium is a multistep process and is of utmost importance in the development of the hallmark vaso-occlusive crisis in sickle cell disease (SCD). However, there lacks a standardized, clinically feasible approach for assessing neutrophil recruitment to the inflamed endothelium for individualized risk stratification and therapeutic response prediction in SCD. Here, we describe a microfluidic device functionalized with E-selectin, a critical endothelial receptor for the neutrophil recruitment process, as a strategy to assess neutrophil binding under physiologic flow in normoxia and clinically relevant hypoxia in SCD. We show that hypoxia significantly enhances neutrophil binding to E-selectin and promotes the formation of neutrophil-platelet aggregates. Moreover, we identified two distinct patient populations: a more severe clinical phenotype with elevated lactate dehydrogenase levels and absolute reticulocyte counts but lowered fetal hemoglobin levels associated with constitutively less neutrophil binding to E-selectin. Mechanistically, we demonstrate that the extent of neutrophil activation correlates with membrane L-selectin shedding, resulting in the loss of ligand interaction sites with E-selectin. We also show that inhibition of E-selectin significantly reduces leukocyte recruitment to activated endothelial cells. Our findings add mechanistic insight into neutrophil-endothelial interactions under hypoxia and provide a clinically feasible means for assessing neutrophil binding to E-selectin using clinical whole blood samples, which can help guide therapeutic decisions for SCD patients.

Abstract
BACKGROUND Eosinophilic chronic rhinosinusitis (ECRS) is a chronic inflammatory condition of the paranasal sinuses characterized by intractable nasal polyps with prominent eosinophil infiltration. These eosinophils are presumably recruited from peripheral blood via vessels expressing peripheral lymph node addressin (PNAd), a set of glycoproteins decorated with 6-sulfo sialyl Lewis x (sLex) glycans that serve as L-selectin ligands. Based on the severity classification algorithm proposed by the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis (JESREC) study group, ECRS is divided into mild, moderate and severe groups; however, as yet there are few reports comparing the clinicopathological differences among these groups. OBJECTIVE Our goal was to elucidate clinicopathological differences among the three different severities of ECRS with special reference to eosinophils and PNAd-expressing vessels. METHODS We performed quantitative immunohistochemical analysis of PNAd-expressing vessels using surgical specimens of nasal polyps from patients exhibiting varying severity of ECRS (n = 35) and from individuals with non-ECRS (n = 10). To this end, we immunostained tissue sections with anti-PNAd and anti-CD34 monoclonal antibodies, and then determined the number of vessels immunolabeled with each antibody. RESULTS The number of eosinophils infiltrating nasal polyps was correlated with ECRS severity. We also found that the PNAd + /CD34 + vessel ratio, namely, the percentage of PNAd-expressing vessels among all vessels, was positively correlated not only with ECRS severity but also with the number of eosinophils infiltrating nasal polyps formed in ECRS. CONCLUSION These results strongly suggest that PNAd-expressing vessels play at least a partial role in eosinophil recruitment to nasal polyps and consequent severity of ECRS.

Abstract
Several diseases, including atherosclerosis, are characterized by inflammation, which is initiated by leukocyte migration to the inflamed lesion. Hence, genes implicated in the early stages of inflammation are potential therapeutic targets to effectively reduce atherogenesis. Algal-derived polysaccharides are one of the most promising sources for pharmaceutical application, although their mechanism of action is still poorly understood. The present study uses a computational method to anticipate the effect of fucoidan and alginate on interactions with adhesion molecules and chemokine, followed by an assessment of the cytotoxicity of the best-predicted bioactive compound for human monocytic THP-1 macrophages by lactate dehydrogenase and crystal violet assay. Moreover, an in vitro pharmacodynamics evaluation was performed. Molecular docking results indicate that fucoidan has a greater affinity for L-and E-selectin, monocyte chemoattractant protein 1 (MCP-1), and intercellular adhesion molecule-1 (ICAM-1) as compared to alginate. Interestingly, there was no fucoidan cytotoxicity on THP-1 macrophages, even at 200 µg/mL for 24 h. The strong interaction between fucoidan and L-selectin in silico explained its ability to inhibit the THP-1 monocytes migration in vitro. MCP-1 and ICAM-1 expression levels in THP-1 macrophages treated with 50 µg/mL fucoidan for 24 h, followed by induction by IFN-γ, were shown to be significantly suppressed as eight- and four-fold changes, respectively, relative to cells treated only with IFN-γ. These results indicate that the electrostatic interaction of fucoidan improves its binding affinity to inflammatory markers in silico and reduces their expression in THP-1 cells in vitro, thus making fucoidan a good candidate to prevent inflammation.

Abstract
Selectin enzymes are glycoproteins and are an important adhesion molecule in the mammalian immune system, especially in the inflammatory response and the healing process of tissues. Selectins play an important role in a variety of biological processes, including the rolling of leukocytes in endothelial cells, a process known as the adhesion cascade. It has recently been discovered and reported that the selectin mechanism plays a role in cancer and thrombosis disease. This process begins with non-covalent interactions-based selectin-ligand binding and the glycans play a role as a connector between cancer cells and the endothelium in this process. The selectin mechanism is critical for the immune system, but it is also involved in disease mechanisms, earning the selectins the nickname "Selectins-The Two Dr. Jekyll and Mr. Hyde Faces". As a result, the drug for selectins should have a multifaceted role and be a dynamic molecule that targets the disease mechanism specifically. This chapter explores the role of selectins in the disease mechanism at the mechanism level that provides the impact for identifying the selectin inhibitors. Overall, this chapter provides the molecular level insights on selectins, their ligands, involvement in normal and disease mechanisms.

Abstract
P2X7 receptors are expressed in different circulating immune cells. Depending on the cell in which they are expressed, their function could vary from activation of the leucine-rich repeat receptor pyrin domain containing 3 (NLRP3) inflammasome or the shedding of different surface receptors. The P2X7 receptor has been involved in the evolution of several inflammatory diseases, and thus its characterization in blood samples is important to investigate its role in human diseases. In this chapter, we present different methods to detect the presence and the activation of P2X7 receptors in whole blood samples. These methods could be used to evaluate the degree of P2X7 receptor activation in blood samples from patients suffering different chronic inflammatory diseases.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV) is an oncogenic etiological factor for Kaposi's sarcoma and primary effusion lymphoma in immunocompromised patients. KSHV utilizes two immune evasion E3 ubiquitin ligases, namely K3 and K5, to downregulate the expression of antigen-presenting molecules and ligands of natural killer (NK) cells in the host cells through an ubiquitin-dependent endocytic mechanism. This allows the infected cells to evade surveillance and elimination by cytotoxic lymphocytes and NK cells. The number of host cell molecular substrates reported for these ubiquitin ligases is limited. The identification of novel substrates for these ligases will aid in elucidating the mechanism underlying immune evasion of KSHV. This study demonstrated that K5 downregulated the cell surface expression of l-selectin, a C-type lectin-like adhesion receptor expressed in the lymphocytes. Tryptophan residue located at the centre of the E2-binding site in the K5 RINGv domain was essential to downregulate l-selectin expression. Additionally, the lysine residues located at the cytoplasmic tail of l-selectin were required for the K5-mediated downregulation of l-selectin. K5 promoted the degradation of l-selectin through polyubiquitination. These results suggest that K5 downregulates l-selectin expression on the cell surface by promoting polyubiquitination and ubiquitin-dependent endocytosis, which indicated that l-selectin is a novel substrate for K5. Additionally, K3 downregulated l-selectin expression. The findings of this study will aid in the elucidation of a novel immune evasion mechanism in KSHV.

Abstract
The lung is one of the deadliest sites of breast cancer metastasis, particularly for triple negative breast cancer (TNBC). We have previously shown that the lung produces several soluble factors that may enhance the metastatic behavior of TNBC, including E-, L-, and P-selectin. In this paper, we hypothesize that lung-derived selectins promote TNBC metastatic behavior and may serve as a potential therapeutic target. Lungs were isolated from mice and used to generate lung-conditioned media (CM). Lung-derived selectins were immunodepleted and TNBC migration and proliferation were assessed in response to native or selectin-depleted lung-CM. A 3D ex vivo pulmonary metastasis assay (PuMA) was used to assess the metastatic progression of TNBC in the lungs of wild-type versus triple-selectin (ELP-/-) knockout mice. We observed that individual lung-derived selectins enhance in vitro migration (p ≤ 0.05), but not the proliferation of TNBC cells, and that ex vivo metastatic progression is reduced in the lungs of ELP-/- mice compared to wild-type mice (p ≤ 0.05). Treatment with the pan-selectin inhibitor bimosiamose reduced in vitro lung-specific TNBC migration and proliferation (p ≤ 0.05). Taken together, these results suggest that lung-derived selectins may present a potential therapeutic target against TNBC metastasis. Future studies are aimed at elucidating the pro-metastatic mechanisms of lung-derived selectins and developing a lung-directed therapeutic approach.

Abstract
Neutrophils, the early responders of the immune system, eliminate intruders, but their over-activation can also instigate tissue damage leading to various autoimmune and inflammatory disease conditions. As approaches causing neutropenia are associated with immunodeficiency, targeting aberrant neutrophil infiltration offers an attractive strategy in neutrophil-centered diseases including acute lung injury. Rho GTPase family proteins Rho, Rac and Cdc42 play important role as regulators of chemotaxis in diverse systems. Rho inhibitors protected against lung injuries, while genetic Rho-deficiency exhibited neutrophil hyperactivity and exacerbated lung injury. These differential outcomes might be due to distinct effects on different cell types or activation/ inhibition of specific signaling pathways responsible for neutrophil polarity, migration and functions. In this study, we explored neutrophil centric effects of Rho signaling mitigation. Consistent with previous reports, Rho signaling inhibitor Y-27632 provided protection against acute lung injury, but without regulating LPS mediated systemic increase of neutrophils in the circulation. Interestingly, the adoptive transfer approach identified a specific defect in neutrophil migration capacity after Rho signaling mitigation. These defects were associated with loss of polarity and altered actin dynamics identified using time-lapse in vitro studies. Further analysis revealed a rescue of stimulation-dependent L-selectin shedding on neutrophils with Rho signaling inhibitor. Surprisingly, functional blocking of L-selectin (CD62L) led to defective recruitment of neutrophils into inflamed lungs. Further, single-cell level analyses identified MAPK signaling as downstream mechanism of Rho signaling and L-selectin mediated effects. p-AKT levels were diminished in detergent resistance membrane-associated signalosome upon Rho signaling inhibition and blockade of selectin. Moreover, inhibition of AKT signaling as well as selectin blocking led to defects in neutrophil polarity. Together, this study identified Rho-dependent distinct L-selectin and AKT signaling mediated regulation of neutrophil recruitment to inflamed lung tissue.

Abstract
(1) Background: Non-alcoholic fatty liver disease (NAFLD) is a growing global health problem. NAFLD progression involves a complex interplay of imbalanced inflammatory cell populations and inflammatory signals such as reactive oxygen species and cytokines. These signals can derive from the liver itself but also from adipose tissue or be mediated via changes in the gut microbiome. We analyzed the effects of a simultaneous migration blockade caused by L-selectin-deficiency and an enhancement of the anti-oxidative stress response triggered by hepatocytic Kelch-like ECH-associated protein 1 (Keap1) deletion on NAFLD progression. (2) Methods: L-selectin-deficient mice (Lsel−/−Keap1flx/flx) and littermates with selective hepatic Keap1 deletion (Lsel−/−Keap1Δhepa) were compared in a 24-week Western-style diet (WD) model. (3) Results: Lsel−/−Keap1Δhepa mice exhibited increased expression of erythroid 2-related factor 2 (Nrf2) target genes in the liver, decreased body weight, reduced epidydimal white adipose tissue with decreased immune cell frequencies, and improved glucose response when compared to their Lsel−/−Keap1flx/flx littermates. Although WD feeding caused drastic changes in fecal microbiota profiles with decreased microbial diversity, no genotype-dependent shifts were observed. (4) Conclusions: Upregulation of the anti-oxidative stress response improves metabolic changes in L-selectin-deficient mice but does not prevent NAFLD progression and shifts in the gut microbiota.

Abstract
Deciding whether to delay non-lifesaving orthopaedic trauma surgery to prevent multiple organ failure (MOF) or sepsis is frequently disputed and largely based on expert opinion. We hypothesise that neutrophils and monocytes differentially express activation markers prior to patients developing these complications. Peripheral blood from 20 healthy controls and 162 patients requiring major orthopaedic intervention was collected perioperatively. Neutrophil and monocyte L-selectin, CD64, CD11, CD18, and CXCR1 expression were measured using flow cytometry. The predictive ability for MOF and sepsis was assessed using the Receiver Operating Characteristic (ROC) comparing to C-reactive protein (CRP). Neutrophil and monocyte L-selectin were significantly higher in patients who developed sepsis. Neutrophil L-selectin (AUC 0.692 [95%CI 0.574–0.810]) and monocyte L-selectin (AUC 0.761 [95%CI 0.632–0.891]) were significant predictors of sepsis and were not significantly different to CRP (AUC 0.772 [95%CI 0.650–0.853]). Monocyte L-selectin was predictive of MOF preoperatively and postoperatively (preop AUC 0.790 [95%CI 0.622–0.958]). CD64 and CRP were predictive of MOF at one-day postop (AUC 0.808 [95%CI 0.643–0.974] and AUC 0.809 [95%CI 0.662–0.956], respectively). In the perioperative period, elevated neutrophil and monocyte L-selectin are predictors of postoperative sepsis. Larger validation studies should focus on these biomarkers for deciding the timing of long bone/pelvic fracture fixation.

Abstract
Progressive multifocal leukoencephalopathy (PML) is attributed to reactivation of the John Cunningham virus (JCV), in the central nervous system as a result of immunosuppression. Low L-selectin (CD62L) expression on cryopreserved T-cells has been advocated as a biomarker for natalizumab related PML in patients with Relapsing-Remitting Multiple Sclerosis. A rare case of PML in an elderly patient without known factors of immunosuppression or immunomodulation is hereby presented. T-cell L-selectin expression levels and serum anti-JCV antibody index were evaluated in order to explore mechanistic insight to the pathways that presumably contribute towards PML development in this rare clinical setting.

Abstract
Objectives A high incidence of pulmonary embolism (PE) is reported in patients with critical coronavirus disease 2019 (COVID‐19). Neutrophils may contribute to this through a process referred to as immunothrombosis. The aim of this study was to investigate the occurrence of neutrophil subpopulations in blood preceding the development of COVID‐19 associated PE. Methods We studied COVID‐19 patients admitted to the ICU of our tertiary hospital between 19‐03‐2020 and 17‐05‐2020. Point‐of‐care fully automated flow cytometry was performed prior to ICU admission, measuring the neutrophil activation/maturation markers CD10, CD11b, CD16 and CD62L. Neutrophil receptor expression was compared between patients who did or did not develop PE (as diagnosed on CT angiography) during or after their ICU stay. Results Among 25 eligible ICU patients, 22 subjects were included for analysis, of whom nine developed PE. The median (IQR) time between neutrophil phenotyping and PE occurrence was 9 (7‐12) days. A significant increase in the immune‐suppressive neutrophil phenotype CD16bright/CD62Ldim was observed on the day of ICU admission (P = 0.014) in patients developing PE compared to patients who did not. Conclusion The increase in this neutrophil phenotype indicates that the increased number of CD16bright/CD62Ldim neutrophils might be used as prognostic marker to predict those patients that will develop PE in critical COVID‐19 patients.

Abstract
Human age-related thymus involution is characterized by loss of developing thymocytes and the thymic epithelial network that supports them, with replacement by adipose tissue. The mechanisms that drive these changes are difficult to study in vivo due to constant trafficking to and from the thymus. We hypothesized that the loss of thymocytes that occurs during human thymic organ cultures could model some aspects of thymus involution and begin to identify mechanisms that drive age-related changes in the thymic microenvironment. Potential mechanistically important candidate molecules were initially identified by screening conditioned media from human thymus organ cultures using antibody microarrays. These candidates were further validated using cultured tissue extracts and conditioned media. Results were compared with gene expression studies from a panel of well-characterized (non-cultured) human thymus tissues from human donors aged 5 days to 78 years. L-selectin released into conditioned media was identified as a biomarker for the content of viable thymocytes within the cultured thymus. Levels of the chemokines CCL21 and CXCL12, likely produced by surviving thymic epithelial cells, increased markedly in conditioned media as thymocytes were lost during culture. Native non-cultured thymus from adults older than 18 years also showed a strong trend toward increased CCL21 expression, in conjunction with significant decreases in thymocyte-related mRNAs compared with thymus from subjects younger than 18 years. Together, these findings demonstrate that use of postnatal human thymus organ cultures can model some aspects of human age-related thymic involution.

Abstract
Selectin ligands are present on the surface of tumor cells, for this reason lowering the L-selectin level in the blood and lymph can indicate presence of the tumor. Therefore the selectin level in the plasma are potential targets for anticancer therapy. We demonstrate the surface enhanced Raman spectroscopy (SERS)-based sensor for the determination of L-selectin level in biological samples that can be used in medical diagnosis. The combination of SERS with the method of multivariate analysis as principle component analysis (PCA) allows to strengthen the presented data analysis. The loadings of PCA permit to indicate those vibration modes, that are the most important for the assumed identification (bands at 1574, 1450, 1292 cm-1 ). Two bands at 1286 and 1580 cm-1 were selected for the determination of the calibration curve (bands intensities I1286 /I1580 ratio). The L-selectin level of biological samples can be read, directly from the calibration curve. The presented sensor is as a sensitive tool with good specificity and selectivity of L-selectin, even in the case of coexistence of P- and E-selectin.

Abstract
BACKGROUND New anti-IL-5 antibodies, mepolizumab and benralizumab, have recently been approved for severe asthma, sharing the same inclusion criteria. OBJECTIVE To contribute on biomarkers research leading to the personalized choice, we investigated L-selectin, Krebs von den Lungen (KL-6), and lymphocyte subsets as bioindicators of airway hyper-responsiveness and remodeling. MATERIALS AND METHODS A cohort of 28 patients affected by severe eosinophilic asthma were treated with anti-IL-5 drugs. According to clinical parameters, patients were subdivided into early and partial responders. Lymphocytes subsets were analyzed through flow cytometry, while KL-6 and sL-selectin were analyzed on serum samples. Clinical, functional, and immunological data at baseline (T0), after 1 month (T1), and 6 months of therapy were collected in a database. RESULTS All treated patients showed an increase in the percentage of forced expiratory volume in the first second (FEV1) and FEV1/forced vital capacity ratio and a decrease of peripheral eosinophils for both drugs after 1 month of treatment. Mepolizumab-treated patients also showed decreased CD8+ and NKT-like cell percentages and a significant increase in sL-selectin concentrations between T0 and T1. Stratifying the cohort of our patients in early and partial responders at T0, they showed a reduction of peripheral eosinophils, sL-selectin and KL-6, while no differences were found at T0 between early and partial responders patients treated with benralizumab. CONCLUSIONS This real-life study provides new insights for the personalized approach to severe asthma therapy. Although preliminary, the results indicate that besides eosinophils, KL-6 and sL-selectin are useful as biomarkers of early response that can also involve in the pathogenesis of severe asthma.

Abstract
STUDY QUESTION Does glycodelin-A (GdA) induce conversion of human peripheral blood CD16-CD56bright natural killer (NK) cells to decidual NK (dNK) cells to facilitate placentation? SUMMARY ANSWER GdA binds to blood CD16-CD56bright NK cells via its sialylated glycans and converts them to a dNK-like cells, which in turn regulate endothelial cell angiogenesis and trophoblast invasion via vascular endothelial growth factor (VEGF) and insulin-like growth factor-binding protein 1 (IGFBP-1) secretion, respectively. WHAT IS KNOWN ALREADY dNK cells are the most abundant leucocyte population in the decidua. These cells express CD16-CD56bright phenotype. Peripheral blood CD16-CD56bright NK cells and hematopoietic precursors have been suggested to be capable of differentiating towards dNK cells upon exposure to the decidual microenvironment. These cells regulate trophoblast invasion during spiral arteries remodelling and mediate homoeostasis and functions of the endothelial cells. GdA is an abundant glycoprotein in the human decidua with peak expression between the 6th and 12th week of gestation, suggesting a role in early pregnancy. Indeed, GdA interacts with and modulates functions and differentiation of trophoblast and immune cells in the human feto-maternal interface. Aberrant GdA expression during pregnancy is associated with unexplained infertility, pregnancy loss and pre-eclampsia. STUDY DESIGN, SIZE, DURATION CD16+CD56dim, CD16-CD56bright and dNK cells were isolated from human peripheral blood and decidua tissue, respectively, by immuno-magnetic beads or fluorescence-activated cell sorting. Human extravillous trophoblasts were isolated from first trimester placental tissue after termination of pregnancy. Biological activities of the cells were studied after treatment with GdA at a physiological dose of 5 μg/mL. GdA was purified from human amniotic fluid by immuno-affinity chromatography. PARTICIPANTS/MATERIALS, SETTING, METHODS Expression of VEGF, CD9, CD49a, CD151 and CD158a in the cells were determined by flow cytometry. Angiogenic proteins in the spent media of NK cells were determined by cytokine array and ELISA. Blocking antibodies were used to study the functions of the identified angiogenic proteins. Endothelial cell angiogenesis was determined by tube formation and trans-well migration assays. Cell invasion and migration were determined by trans-well invasion/migration assay. Binding of normal and de-sialylated GdA, and expression of L-selectin and siglec-7 on the NK cells were analysed by flow cytometry. The association between GdA and L-selectin on NK cells was confirmed by immunoprecipitation. Extracellular signal-regulated protein kinases (ERK) activation was determined by Western blotting and functional assays. MAIN RESULTS AND THE ROLE OF CHANCE GdA treatment enhanced the expression of dNK cell markers CD9 and CD49a and the production of the functional dNK secretory product VEGF in the peripheral blood CD16-CD56bright NK cells. The spent media of GdA-treated CD16-CD56bright NK cells promoted tube formation of human umbilical vein endothelial cells and invasiveness of trophoblasts. These stimulatory effects were mediated by the stimulatory activities of GdA on an ERK-activation dependent production of VEGF and IGFBP-1 by the NK cells. GdA had a stronger binding affinity to the CD16-CD56bright NK cells as compared to the CD16+CD56dim NK cells. This GdA-NK cell interaction was reduced by de-sialylation. GdA interacted with L-selectin, expressed only in the CD16-CD56bright NK cells, but not in the CD16+CD56dim NK cells. Anti-L-selectin functional blocking antibody suppressed the binding and biological activities of GdA on the NK cells. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Some of the above findings are based on a small sample size of peripheral blood CD16-CD56bright NK cells. These results need to be confirmed with human primary dNK cells. WIDER IMPLICATIONS OF THE FINDINGS This is the first study on the biological role of GdA on conversion of CD16-CD56bright NK cells to dNK-like cells. Further investigation on the glycosylation and functions of GdA will enhance our understanding on human placentation and placenta-associated complications with altered NK cell biology.

Abstract
In seminiferous epithelium, tight junctions (TJs) between adjacent Sertoli cells constitute the blood-testis barrier and must change synchronically for germ cells to translocate from the basal to the adluminal compartment during the spermatogenic cycle. Rho GTPase activation through stimulation with specific L-selectin ligands has been proposed to modulate tight junctional dynamics. However, little is known regarding the role of Ca+2 dynamics in Sertoli cell and how Ca+2 relays L-selectin signals to modulate Rho GTPase activity in Sertoli cells, thus prompting us to investigate the Ca+2 flux induced by L-selectin ligand in ASC-17D cells. Using fluorescent real-time image, we first demonstrated the increase of intracellular Ca+2 level following L-selectin ligand stimulation. This Ca+2 increase was inhibited in ASC-17D cells pretreated with nifedipine, the L-type voltage-operated Ca+2 channel (VOCC) blocker, but not mibefradil, the T-type VOCC blocker. We then demonstrated the up-regulation of Rho and Rac1 in ASC-17D cells following the administration of L-selectin ligand, and the pre-treatment with nifedipine, but not mibefradil, prior to L-selectin ligand-binding abolished the activation of both Rho and Rac1. Together, we conclude that the activation of L-selectin induces Ca+2 influx through the L-type VOCC, which up-regulates Rho and Rac1 proteins, in ASC-17D cells.

Abstract
Head and neck squamous cell carcinoma (HNSCC) cells bind to lymphocytes via L-selectin in a shear-dependent manner. This interaction takes place exclusively under low-shear stress conditions, such as those found within the lymph node parenchyma. This represents a novel functional role for L-selectin-selectin ligand interactions. Our previous work has characterized as-of-yet unidentified L-selectin ligands expressed by HNSCC cells that are specifically active under conditions of low shear stress consistent with lymph flow. Using an affinity purification approach, we now show that nucleolin expressed on the surface of HNSCC cells is an active ligand for L-selectin. Parallel plate chamber flow-based experiments and atomic force microscopy (AFM) experiments show that nucleolin is the main functional ligand under these low-force conditions. Furthermore, AFM shows a clear relationship between work of deadhesion and physiological loading rates. Our results reveal nucleolin as the first major ligand reported for L-selectin that operates under low-shear stress conditions.

Abstract
The aim of the research was to investigate the anti-endotoxin and anti-inflammatory effects of Sinomenine, an agent commonly found in Chinese herbal medicines. Endotoxin (i.e., 1 mg lipopolysaccharide (LPS)/kg)) was administered via intraperitoneal (IP) injection to piglets in high-, middle-, and low-dose sinomenine groups. Piglets were then treated with 1, 5 or 10 mg/kg sinomenine, intramuscularly (i.m.), 3 hr after LPS. Vehicle was administered, as above, to drug control group piglets followed 3 hr later by 10 mg/kg sinomenine i.m.. LPS control group piglets were challenged with 1 mg/kg LPS IP, followed by vehicle i.m., and naïve control piglets were treated with normal saline IP, followed by normal saline i.m., as above. Temperatures were measured, and blood samples were collected from the precaval veins of piglets at 12, 24, and 48 hr post-LPS or vehicle injection. Clinical signs were recorded, and index levels were analyzed via ELISA. Sinomenine was found to reduce the incidence and severity of LPS-induced toxicities, including body temperature elevation, cell adhesion, and systemic inflammation. These data suggest that sinomenine may be effective for regulating inflammatory responses and has the potential for use as an anti-endotoxin therapy.

Abstract
INTRODUCTION In this study, the serum levels of soluble intercellular adhesion molecule 1 (ICAM-1), P-, E-, and L-selectins were investigated in seriously eye-injured patients exposed to sulfur mustard (SM). MATERIAL AND METHODS A total of 128 individuals with SM-induced serious eye injuries and 31 healthy male controls were included in this study. The serum concentration of soluble forms of adhesion molecules was measured by enzyme-linked immunosorbent assay (ELISA) method. RESULT The serum level of soluble ICAM-1 was significantly higher in the SM-exposed individuals with an abnormality in tear meniscus height, corneal verticillata, and pannus compared with SM-exposed individuals without these abnormalities. There were no significant differences in the level of all three measured selectins between the SM-exposed group and the control groups. SM-exposed individuals with corneal defect had a significantly higher level of soluble E-selectin than SM-exposed individuals without this abnormality. The serum level of soluble P-selectin in the SM-exposed group with limbal abnormality was significantly lower than that in the SM-exposed without this abnormality; also it was significantly higher in SM-exposed group with fundus abnormality compared to that in the control group or SM-exposed group without this abnormality. CONCLUSION The changes in the levels of selectins and ICAM-1 in the SM-exposed group with various ocular abnormalities is a defense mechanism against the toxicity of SM. Further analysis is required to understand the molecular mechanisms of the relationship between adhesion molecules with ocular complications in SM-exposed individuals.

Abstract
Neutrophils are principal host innate immune cell responders to mastitis infections. Thus, therapies have been developed that target neutrophil expansion. This includes the neutrophil-stimulating cytokine granulocyte colony-stimulating factor (gCSF). Pegylated gCSF (PEG-gCSF; Imrestor, Elanco Animal Health, Greenfield, IN) has been shown to reduce the natural incidence of mastitis in periparturient cows in commercial settings and reduce severity of disease against experimental mastitis challenge. Pegylated gCSF stimulates neutrophil expansion but also induces changes in monocyte and lymphocyte circulating numbers, surface protein expression changes, or both. We hypothesized that PEG-gCSF modulates surface expression of monocytes and neutrophils and facilitates their migration to the mammary gland. We challenged 8 mid-lactation Holsteins with approximately 150 cfu of Staphylococcus aureus (Newbould 305) in a single quarter via intramammary infusion. All animals developed chronic infections as assessed by bacteria counts and somatic cell counts (SCC). Ten to 16 wk postchallenge, 4 of the animals were treated with 2 subcutaneous injections of PEG-gCSF 7 d apart. Complete blood counts, SCC, bacterial counts, milk yield, feed intake, neutrophils extracellular trap analysis, and flow cytometric analyses of milk and blood samples were performed at indicated time points for 14 d after the first PEG-gCSF injection. The PEG-gCSF-treated cows had significantly increased numbers of blood neutrophils and lymphocytes compared with control cows. Flow cytometric analyses revealed increased surface expression of myeloperoxidase (MPO) on neutrophils and macrophages in milk but not in blood of treated cows. Neutrophils isolated from blood of PEG-gCSF-treated cows had decreased surface expression of CD62L (L-selectin) in blood, consistent with cell activation. Surprisingly, CD62L cell surface expression was increased on neutrophils and macrophages sourced from milk from treated animals compared with cells isolated from controls. The PEG-gCSF-treated cows did not clear the S. aureus infection, nor did they significantly differ in SCC from controls. These findings provide evidence that PEG-gCSF therapy modifies cell surface expression of neutrophils and monocytes. However, although surface MPO+ cells accumulate in the mammary gland, the lack of bacterial control from these milk-derived cells suggests an incomplete role for PEG-gCSF treatment against chronic S. aureus infection and possibly chronic mammary infections in general.

Abstract
Aim: Levels of VCAM-1, ICAM-1 and selectins in gestational diabetes mellitus (GDM) subjects are an indication of endothelial dysfunction predicting the future metabolic consequence via metabolic memory effect. Materials & methods: This cross-sectional study was conducted in 92 pregnant women and serum endothelial cell adhesion molecules were measured using Randox biochip analyzer. Results: Significantly elevated serum level of VCAM-1 was found in GDM subjects and in greater than equal to one parity categorized GDM group when compared with control. The correlation of parity and P-selectin was statistically significant in GDM subjects. Conclusion: Elevated levels of endothelial cell adhesion molecules in GDM women indicate an imbalance in vascular function. Transient hyperglycemia during pregnancy may induce persistent modifications to the memory cells and GDM subjects are more prone to develop future consequences.

Abstract
Recent data have demonstrated that chronic inflammation is a crucial component of tumor initiation and progression. We previously reported that immature myeloid-derived suppressor cells (MDSCs) with immunosuppressive activity toward effector T cells were expanded in experimental chronic inflammation. We hypothesized that elevated levels of MDSCs, induced by chronic inflammation, may contribute to the progression of tumor growth. Using the Ehrlich carcinoma animal model, we found increased tumor growth in mice with chronic adjuvant arthritis, which was accompanied by a persistent increase in the proportion of splenic monocytic and granulocytic MDSCs expressing CD62L (L-selectin), when compared to tumor mice without adjuvant arthritis. Depletion of inflammation-induced MDSCs resulted in decreased tumor growth. In vitro studies demonstrated that increased expression of CD62L by MDSCs was mediated by TNFα, elevated concentrations of which were found in tumor mice subjected to chronic inflammation. Moreover, the addition of exogenous TNFα markedly enhanced the suppressive activity of bone marrow-derived MDSCs, as revealed by the ability to impair the proliferation of CD8+ T cells in vitro. This study provides evidence that chronic inflammation may promote tumor growth via induction of CD62L expression by MDSCs that can facilitate their migration to tumor and lymph nodes and modulation of their suppressor activity.

Abstract
PURPOSE The aim of this research was to design dexamethasone palmitate (DP) loaded sialic acid modified liposomes, with the eventual goal of using peripheral blood neutrophils (PBNs) that carried drug-loaded liposomes to improve the therapeutic capacity for rheumatoid arthritis (RA). METHODS A sialic acid - cholesterol conjugate (SA-CH) was synthesized and anchored on the surface of liposomal dexamethasone palmitate (DP-SAL). The physicochemical characteristics and in vitro cytotoxicity of liposomes were evaluated. Flow cytometry and confocal laser scanning microscopy were utilized to investigate the accumulation of liposomes in PBNs. The adjuvant-induced arthritis was adopted to investigate the targeting ability and anti-inflammatory effect of DP loaded liposomes. RESULTS Both DP-CL and DP-SAL existed an average size less than 200 nm with remarkably high encapsulation efficiencies more than 90%. In vitro and in vivo experiments manifested SA-modified liposomes provided a reinforced accumulation of DP in PBNs. As well, DP-SAL displayed a greater degree of accumulation in the joints and a stronger anti-inflammatory effect in terms of RA suppression. CONCLUSIONS SA-modified liposomal DP was a promising candidate for RA-targeting treatment through the neutrophil-mediated drug delivery system.

Abstract
Normal function of the adaptive immune system requires trafficking of T cells between the blood and lymphoid organs. Lymphocyte homing to lymph nodes requires that they cross endothelial barriers present in blood vessels and lymphatics. This multi-step process requires a remodeling of the lymphocyte plasma membrane, which is mediated by the dynamic re-arrangement of the actin cytoskeleton. Pak1 plays a central role in cell morphology, adhesion and migration in various cell types. Here we demonstrate that Pak1 is required for activated CD4+ T cell trafficking to lymph nodes. Pak1 deficiency in T cells causes a defect in the transcription of CCR7 and L-selectin, thereby altering lymphocyte trafficking. Additionally, we report an increase in L-selectin shedding in Pak1-deficient T cells, which correlates with a decrease in the recruitment of calmodulin to the cytoplasmic tail of L-selectin during T cell activation. Overall, our findings demonstrate that by regulating the expression of two major lymph node homing molecules, L-selectin and CCR7, Pak1 mediates activated CD4+ T cell trafficking.

Abstract
Eosinophilic chronic rhinosinusitis (ECRS) is characterised by formation of nasal polyps with prominent eosinophilic infiltration; however, how eosinophils are recruited in this pathological setting remains unclear. In the present study, we carried out quantitative immunohistochemical analysis of nasal polyps associated with ECRS (n=30) and non-ECRS (n=30) to evaluate expression of an L-selectin ligand peripheral lymph node addressin (PNAd) on vascular endothelial cells. We found that PNAd was induced primarily on the luminal surface of venular vessels present in nasal mucosa in both ECRS and non-ECRS, while the number of PNAd-expressing vessels in ECRS significantly exceeded that seen in non-ECRS. Moreover, the number of eosinophils attached to the luminal surface of PNAd-expressing vessels in ECRS was significantly greater than that in non-ECRS, while the number of neutrophils and lymphocytes attached did not differ significantly between conditions. Furthermore, eosinophils, which express cell surface L-selectin, adhered to PNAd-expressing Chinese hamster ovary (CHO) cells in a calcium-dependent manner, and that adhesion was significantly inhibited by pretreatment of eosinophils with DREG-56, an anti-human L-selectin monoclonal antibody. These findings combined suggest that interaction between L-selectin and PNAd plays at least a partial role in eosinophil recruitment in human nasal mucosa with ECRS.

Abstract
Selectins dominate the formation of the metastasis niche and are considered important targets for exploring antimetastatic drugs. In this study, we evaluated the effect of the marine drug propylene glycol alginate sodium sulfate (PSS) and a series of PSS derivatives on P-, L- or E-selectin-mediated binding with tumor cells. We found that PSS effectively prevented the binding of P- or L-selectin with tumor cells. Moreover, the structure-activity relationship study indicated that the activity of PSS is related to the sulfate group at the C-2/C-3 position, the propylene glycol substituent at the C-6 position, the ratio of guluronic acid to mannuronic acid, and the molecular weight. Additionally, PSS derivatives significantly suppressed lung metastasis in vivo. Our results demonstrated that PSS and its derivatives are potential antimetastatic drugs candidates.

Abstract
Workers chronically exposed to respirable crystalline silica (CS) are susceptible to adverse health effects like silicosis and lung cancer. This study aimed to investigate potential early peripheral biomarkers of inflammation and oxidative stress in miners. The subjects enrolled in this study were occupationally unexposed workers (OUW, n = 29) and workers exposed to crystalline silica (WECS), composed by miners, which were divided into two subgroups: workers without silicosis (WECS I, n = 39) and workers diagnosed with silicosis, retired from work (WECS II, n = 42). The following biomarkers were evaluated: gene expression of L-selectin, CXCL2, CXCL8 (IL-8), HO-1, and p53; malondialdehyde (MDA) plasma levels and non-protein thiol levels in erythrocytes. Additionally, protein expression of L-selectin was evaluated to confirm our previous findings. The results demonstrated that gene expression of L-selectin was decreased in the WECS I group when compared to the OUW group (p < 0.05). Regarding gene expression of CXCL2, CXCL8 (IL-8), HO-1, and p53, significant fold change decreases were observed in workers exposed to CS in relation to unexposed workers (p < 0.05). The results of L-selectin protein expression in lymphocyte surface corroborated with our previous findings; thus, significant downregulation in the WECS groups was observed compared to OUW group (p < 0.05). The MDA was negatively associated with the gene expression of CXCL-2, CXCL8 (IL-8), and p53 (p < 0.05). The participants with silicosis (WECS II) presented significant increased non-protein thiol levels in relation to other groups (p < 0.05). Taken together, our findings may contribute to help the knowledge about the complex mechanisms involved in the silicosis pathogenesis and in the risk of lung cancer development in workers chronically exposed to respirable CS.

Abstract
Neutrophils destroy invading microorganisms by phagocytosis by bringing them into contact with bactericidal substances, among which ROS are the most important. However, ROS also function as important physiological regulators of cellular signaling pathways. Here, we addressed the involvement of oxygen derivatives in the regulation of human neutrophil rolling, an essential component of the inflammatory response. Flow experiments using dihydroethidium-preloaded human neutrophils showed that these cells initiate an early production of intracellular ROS during the rolling phase of the adhesion cascade, a phenomenon that required cell rolling, and the interaction of the chemokine receptor CXCR2 with their ligand CXCL8. Flow cytometry experiments demonstrated that L-selectin shedding in neutrophils is triggered by ROS through an autocrine-paracrine mechanism. Preincubation of neutrophils with the NADPH oxidase complex inhibitor diphenyleniodonium chloride significantly increased the number of rolling neutrophils on endothelial cells. Interestingly, the same effect was observed when CXCL8 signaling was interfered using either a blocking monoclonal antibody or an inhibitor of its receptor. These findings indicate that, in response to CXCL8, neutrophils initiate ROS production during the rolling phase of the inflammatory response. This very early ROS production might participate in the modulation of the inflammatory response by inducing L-selectin shedding in neutrophils.

Abstract
L-selectin, a lectin-like receptor on all leukocyte classes, functions in adhesive and signaling roles in the recruitment of myeloid cells from the blood to sites of inflammation. Here, we consider L-selectin as a determinant of neurological recovery in a murine model of spinal cord injury (SCI). Spinal cord-injured, L-selectin knock-out (KO) mice (male) showed improved long-term recovery with greater white matter sparing relative to wild-type (WT) mice and reduced oxidative stress in the injured cord at 72 h post-SCI. There was a partial and transient reduction in accumulation of neutrophils in the injured spinal cords of KOs at 24 h post-injury. To complement these findings with KO mice, we sought a pharmacologic means for lowering L-selectin levels. We found that diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), induced the shedding of L-selectin from the cell surface of myeloid subsets, specifically neutrophils and non-classical monocytes, in the blood and the injured spinal cord. Diclofenac administration to injured WT mice enhanced neurological recovery to a level comparable to that of KOs but did not improve recovery in KOs. While diclofenac treatment had no effect on myeloid cell accumulation, there was a reduction in oxidative stress at 72 h post-SCI. These findings implicate L-selectin in secondary pathogenesis beyond a role in leukocyte recruitment and raise the possibility of repurposing diclofenac for the treatment of SCI.

Abstract
Workers involved in mining activities are exposed to crystalline silica, which leads to constant pulmonary inflammatory reactions and severe oxidative damage, resulting in silicosis. In this work, we aimed to evaluate inflammatory and oxidative stress parameters as potential early biomarkers of effect to assess crystalline silica toxicity in workers who had occupational exposure during mining. We enrolled 38 workers exposed to crystalline silica (WECS), 24 individuals with silicosis (IWS), and 30 occupationally unexposed workers (OUW), a total of 92 participants. The WECS were divided into 2 groups, according to the time of exposure: 19 workers with 1-15 years of occupational exposure (WECS I) and 19 workers with >16 years of occupational exposure (WECS II). The inflammatory parameters assessed were L-selectin, β-2 integrin, and intercellular adhesion molecule-1 (ICAM-1) surface protein expression in lymphocytes and monocytes, complement C3 and C4, high sensitivity C-reactive protein (hsCRP), and adenosine deaminase (ADA) in serum. Plasma levels of malondialdehyde (MDA) and serum levels of vitamin C were determined as biomarkers of oxidative stress. Biochemical and hematological parameters were also investigated. L-selectin surface protein expression was significantly decreased in the WECS II group (p < 0.05), indicating the importance of this immune system component as a potential marker of crystalline-silica-induced toxicity. The MDA levels were significantly increased in the WECS I, WECS II, and IWS groups compared to the OUW group (p < 0.05). Vitamin C levels were decreased, while C3, hsCRP, ADA, and aspartate aminotransferase (AST) levels were increased in the IWS group compared to the OUW group (p < 0.05). Glucose and urea levels were significantly higher in the WECS I, II, and IWS groups compared to the OUW group (p < 0.05). Negative partial association was found between L-selectin and time of exposure (p < 0.001), supporting the relevance of this biomarker evaluation in long-term exposure to crystalline silica. Significant associations were also observed among inflammatory and oxidative stress biomarkers. Therefore, our results demonstrated the relevance of L-selectin as a potential peripheral biomarker for monitoring crystalline silica-induced toxicity in miners after chronic exposure, before silicosis has developed. However, more studies are necessary for better understanding of the use L-selectin as an early biomarker in exposed workers.

Abstract
The murine maternal immune activation (MIA) offspring model enables longitudinal studies to explore aberrant social behaviors similar to those observed in humans. High levels of cytokines, chemokines and cell adhesion molecules (CAM) have been found in the plasma and/or brains of psychiatric patients. We hypothesized that upregulation of the systemic or brain immune response has an augmenting effect by potentially increasing the interplay between the neuronal and immune systems during the growth of the MIA offspring. In this study, a C57BL/6j MIA female offspring model exhibiting social deficits was established. The expression of fetal interferon (IFN)-stimulated (gbp3, irgm1, ifi44), adolescent immunodevelopmental transcription factor (eg, r2, tfap2b), hormone (pomc, hcrt), adult selectin (sell, selp) and neuroligin (nlgn2) genes was altered. Systemic upregulation of endogenous IL-10 occurred at the adult stage, while both IL-1β and IL-6 were increased and persisted in the sera throughout the growth of the MIA offspring. The cerebral IL-6 levels were endogenously upregulated, but both MCP-1 (macrophage inflammatory protein-1) and L-selectin levels were downregulated at the adolescent and/or adult stages. However, the MIA offspring were susceptible to lipopolysaccharide (LPS) stimulation. After reinjecting the MIA offspring with LPS in adulthood, a variety of sera and cerebral cytokines, chemokines and CAMs were increased. Particularly, both MCP-1 and L-selectin showed relatively high expression in the brain compared with the expression levels in phosphate-buffered saline (PBS)-treated offspring injected with LPS. Potentially, MCP-1 was attracted to the L-selectin-mediated immune cells due to augmentation of the immune response following stimulation in MIA female offspring.

Abstract
Understanding the mechanism of interactions of nanomaterials at biointerfaces is a crucial issue to develop new antimicrobial vectors. In this work, a series of water-soluble fullerene-polyglycerol sulfates (FPS) with different fullerene/polymer weight ratios and varying numbers of polyglycerol sulfate branches are synthesized, characterized, and their interactions with two distinct surfaces displaying proteins involved in target cell recognition are investigated. The combination of polyanionic branches with a solvent exposed variable hydrophobic core in FPS proves to be superior to analogs possessing only one of these features in preventing interaction of vesicular stomatitis virus coat glycoprotein (VSV-G) with baby hamster kidney cells serving as a model of host cell. Interference with L-selectin-ligand binding is dominated by the negative charge, which is studied by two assays: a competitive surface plasmon resonance (SPR)-based inhibition assay and the leukocyte cell (NALM-6) rolling on ligands under flow conditions. Due to possible intrinsic hydrophobic and electrostatic effects of synthesized compounds, pico- to nanomolar half maximal inhibitory concentrations (IC50 ) are achieved. With their highly antiviral and anti-inflammatory properties, together with good biocompatibility, FPS are promising candidates for the future development towards biomedical applications.

Abstract
BACKGROUND The inflammatory response to Mycobacterium tuberculosis bacilli influences tuberculosis (TB) progression. In this study, we aimed to identify the Phe206Leu polymorphism and serum L-selectin level in TB patients, compared to healthy individuals. METHODS Ninety patients with a diagnosis of TB and 90 healthy controls were selected in this study. The serum L-selectin level was determined, using ELISA. L-selectin polymorphism was also evaluated using PCR. For data analysis, SPSS was used at a significance level of 0.05. RESULTS According to the findings, the mean±SD age of the participants was 57.5 ± 18.4 and 56.5 ± 17.5 years in the TB and healthy groups, respectively. The TB group showed a significantly higher serum L-selectin level (1721.1 ± 330.9) versus the healthy controls (1624 ± 279). The L-selectin Phe allele frequencies were higher than the Leu allele frequencies in the main population, whereas the patients and controls were not significantly different. Eight (0.04%) subjects had Leu/Leu genotypes, 84 (46.6%) carried Phe/Leu genotypes, and 88 (48.8%) had Phe/Phe genotypes. Our results showed that the groups were not significantly different regarding L-selectin genotypes. CONCLUSION TB patients had a significantly higher serum L-selectin level, compared to the controls. Based on the findings, the incidence of TB and L-selectin polymorphism in the Phe206Leu gene had no significant association.

Abstract
Staphylococcus aureus is a skin- and respiratory tract-colonizing bacterium and is the leading cause of community-acquired skin infections. Dissemination of these bacteria into systemic circulation causes bacteremia, which has a high mortality rate. Therefore, understanding the immunologic barriers that prevent dissemination is critical to developing novel treatments. In this study, we demonstrate that an S. aureus breach across skin leads to some migration of the pathogen to the draining lymph node, but no further. While subcapsular sinus (SCS) macrophage in lymph nodes were important in detaining S. aureus, a rapid complement-dependent neutrophil recruitment (independent of the SCS macrophage) via high endothelial venules (HEVs) resulted in high numbers of neutrophils that intercepted the bacteria in the lymph nodes. Peripheral Node Addressin together with its two ligands, L-selectin and platelet P-selectin, are critical for recruiting neutrophils via the HEVs. Almost no neutrophils entered the lymph nodes via lymphatics. Neutrophils actively phagocytosed S. aureus and helped sterilize the lymph nodes and prevent dissemination to blood and other organs.

Abstract
L-selectin is a type I transmembrane cell adhesion molecule expressed on most circulating leukocytes, including neutrophils. Engagement of L-selectin with endothelial-derived ligands initiates neutrophil tethering and rolling behaviour along luminal walls of post-capillary venules, constituting the first step of the multi-step adhesion cascade. There is a large body of evidence to suggest that signalling downstream of L-selectin can influence neutrophil behaviour: adhesion, migration and priming. This review will cover aspects of L-selectin form and function and introduce the “triad of L-selectin regulation”, highlighting the inextricable links between adhesion, signalling and ectodomain shedding and also highlighting the cytosolic proteins that interconnect them. Recent advances in how L-selectin impacts priming, transendothelial migration (TEM) and cell polarity will also be discussed.

Abstract
The relationship between dendritic cells (DCs) and L-selectin in the progress of atherosclerosis is unclear. Here, we used L-selectin co-cultured with DCs to investigate the effect of L-selectin on the maturation of DCs in vitro Monocytes derived DCs were isolated and cultured from human peripheral blood. After being stimulated with L-selectin and/or its antagonist for 24-48 hours, the feather of cells was observed by the electron microscope. The expression of mature antigens CD1a, CD80, CD83, and CD86 were investigated by flow cytometric analysis (FACS). RT-PCR and FACS were used to detect the mRNA and protein expression of Toll-like receptor 4(TLR-4). We found that only the cells of giving L-selectin have the mature special feature for irregular shapes. DCs which were stimulated by L-selectin have a larger number of expressing CD1a, CD80, CD83, and CD86 compared with non-stimulated and cultured with L-selectin antagonist. The transcript levels of TLR4 were significantly higher after L-selectin and lipopolysaccharide (LPS) stimulated. And the antagonist of L-selectin can deeply decrease the expression of CD1a, CD80, CD83, and CD86 on DCs appeared to coincide with the level of TLR4 transcription. The results demonstrate L-selectin can promote the maturation of DCs via up-regulation the expression of TLR4.

Abstract
L-Selectin, a cell-adhesion receptor on the surface of most leukocytes, contains seven N-glycosylation sites. In order to obtain the crystal structure of human L-selectin, we expressed a shortened version of L-selectin comprising the C-type lectin and EGF-like domains (termed LE) and systematically analysed mutations of the three glycosylation sites (Asn22, Asn66 and Asn139) in order to reduce macroheterogeneity. After we further removed microheterogeneity, we obtained crystals that diffracted X-rays up to 1.9 Å from a variant (LE010) with exchanges N22Q and N139Q and one GlcNAc2 Man5 N-glycan chain attached to Asn66. Crystal-structure analysis showed that the terminal mannose of GlcNAc2 Man5 of one LE010 molecule was coordinated to Ca2+ in the binding site of a symmetry-related LE010. The orientation of the lectin and EGF-like domain was similar to the described "bent" conformation of E- and P-selectins. The Ca2+ -binding site reflects the binding mode seen in E- and P-selectin structures co-crystallised with ligands.

Abstract
Inflammation is a complex process involving the contribution of leukocytes and blood vessels, which collectively aim to restore homeostasis following injury to the body. Leukocytes are essential front-line responders to infectious or noninfectious injury and can be deployed within minutes of sensing damage. A typical inflammatory response leads to the exit of circulating leukocytes into the surrounding extravascular space, which follows a series of increasingly adhesive events - collectively termed the "multistep adhesion cascade." The Ras homology (Rho) family of small GTPases (RhoGTPases) are intracellular proteins involved in translating extracellular signals into cellular behavior, such as adhesion and migration. This chapter focuses on how to prepare, perform, and monitor RhoGTPase activation assays using classic pull-down assays. Although this chapter focuses on RhoGTPase signaling downstream of L-selectin clustering, the methods outlined here can be applied to analyzing RhoGTPase activity in response to stimulating other surface receptors.

Abstract
Myeloid-derived suppressor cells (MDSC) contribute to an immunosuppressive network that drives cancer escape by disabling T cell adaptive immunity. The prevailing view is that MDSC-mediated immunosuppression is restricted to tissues where MDSC co-mingle with T cells. Here we show that splenic or, unexpectedly, blood-borne MDSC execute far-reaching immune suppression by reducing expression of the L-selectin lymph node (LN) homing receptor on naïve T and B cells. MDSC-induced L-selectin loss occurs through a contact-dependent, post-transcriptional mechanism that is independent of the major L-selectin sheddase, ADAM17, but results in significant elevation of circulating L-selectin in tumor-bearing mice. Even moderate deficits in L-selectin expression disrupt T cell trafficking to distant LN. Furthermore, T cells preconditioned by MDSC have diminished responses to subsequent antigen exposure, which in conjunction with reduced trafficking, severely restricts antigen-driven expansion in widely-dispersed LN. These results establish novel mechanisms for MDSC-mediated immunosuppression that have unanticipated implications for systemic cancer immunity. DOI:http://dx.doi.org/10.7554/eLife.17375.001
