Abstract
CONTEXT Relapse and recurrence rates of pressure injuries (PIs) are very high in spinal cord injured patients. That is the reason why alternative therapies, such the stem cells derived from bone marrow, have been developed. OBJECTIVE To compare this new technique of infiltration-infusion of mononuclear cells from bone marrow with conventional surgery. DESIGN A retrospective study was carried out in patients with spinal cord injuries who had PIs, category III/IV, in the pelvic area, during a 14-year follow-up period. SETTING One group was treated with conventional surgery and, in the other group, mononuclear cells were infused. PARTICIPANTS One hundred and forty-nine patients were registered, 63 (42.3%) in the conventional surgery group and 86 (57.7%) in the mononuclear cell group. RESULTS A comparative study between these 2 groups was carried out. There were no significant differences in ulcer healing in the first 6 months, but 6 months and one-year post-treatment, they were found. At 6 months, no patient in the conventional surgery group showed dehiscence or fistulization of the wound and, one year after surgery, only 3.17% recurred in the conventional group. In addition, there was a statistically significant relationship between days of hospitalization and the type of bacterial contamination and the intervention group. CONCLUSION Bone marrow mononuclear cell infusion-infiltration is an alternative treatment for PIs and fistula during the first 6 months, instead of conventional surgery. However, in the medium-long term, conventional surgery is more effective.

Abstract
BACKGROUND Bone marrow-derived mesenchymal stromal cells (BM-MSCs) are used in regenerative medicine and related research involving immunomodulatory, anti-inflammatory, anti-fibrotic and regenerative functions. Isolation of BM-MSCs from samples obtained during total hip arthroplasty (THA) is routinely possible. Advanced age and comorbidities of the majority of patients undergoing THA limit their applicability. Our study aimed to evaluate the potential of bone marrow obtained during periacetabular osteotomy (PAO) as a novel source of BM-MSCs from young donors by analyzing cell yield and cell characteristics. METHODS Bone samples were obtained from the anterior Os ilium or superior Os pubis during PAO and from the femoral cavity during primary THA. Isolation of bone marrow-derived mononuclear cells (BM-MNCs) was performed by density gradient centrifugation. The samples from PAO and THA patients were compared in terms of BM-MSC yield, colony formation and the proportion of BM-MSCs within the BM-MNC population using flow cytometry analysis. The cells were characterized based on the expression of BM-MSC-specific surface markers. The functionality of the cells was compared by quantifying post-thaw viability, metabolic activity, proliferation capacity, senescence-associated beta galactosidase (SA-β-gal) expression, trilineage differentiation potential and major secretome proteins. RESULTS Isolation of BM-MNCs was possible in a reliable and reproducible manner when using bone from PAO containing more than 0.24 g bone marrow. PAO patients were younger than patients of the THA group. Bone obtained during PAO contained less bone marrow and led to a lower BM-MSC number after the first cell culture passage compared to BM-MSCs obtained during THA. BM-MSCs from PAO samples are characterized by a higher proliferation capacity. This results in a higher yield in cell culture passage two, when normalized to the sample weight. BM-MSCs from PAO patients showed increased secretion of TGF-β1, TIMP2, and VEGF upon osteogenic differentiation. BM-MSCs from PAO and THA patients revealed similar results regarding the onset of SA-β-gal expression and trilineage differentiation capacity. CONCLUSIONS We suggest that bone obtained during PAO is a promising novel source for BM-MSCs from young donors. Limited absolute cell yield due to low sample weight must be considered in early cell culture passages and might be critical for the range of clinical applications possible for BM-MSCs from this source. The higher proliferation capacity and increased growth factor secretion of BM-MSCs from young donors may be beneficial for future regenerative cell therapies, in vitro models, and tissue engineering.

Abstract
Endothelial Ca2+ signaling has important roles to play in maintaining pregnancy associated vasodilation in the utero-placenta. Inflammatory cytokines, often elevated in vascular complications of pregnancy, negatively regulate ATP-stimulated endothelial Ca2+ signaling and associated nitric oxide production. However, the role of direct engagement of immune cells on endothelial Ca2+ signaling and therefore endothelial function is unclear. To model immune-endothelial interactions, herein, we evaluate the effects of peripheral blood mononuclear cells (PBMCs) in short-term interaction with human umbilical vein endothelial cells (HUVECs) on agonist-stimulated Ca2+ signaling in HUVECs. We find that mononuclear cells (10:1 and 25:1 mononuclear: HUVEC) cause decreased ATP-stimulated Ca2+ signaling; worsened by activated mononuclear cells possibly due to increased cytokine secretion. Additionally, monocytes, natural killers, and T-cells cause decrease in ATP-stimulated Ca2+ signaling using THP-1 (monocyte), NKL (natural killer cells), and Jurkat (T-cell) cell lines, respectively. PBMCs with Golgi-restricted protein transport prior to interaction with endothelial cells display rescue in Ca2+ signaling, strongly suggesting that secreted proteins from PBMCs mediate changes in HUVEC Ca2+ signaling. We propose that endothelial cells from normal pregnancy interacting with PBMCs may model preeclamptic endothelial-immune interaction and resultant endothelial dysfunction.

Abstract
BACKGROUND This study aimed to identify the density of mononuclear cells (MNCs) and CD34+ cells in the bone marrow of patients with three neurologic conditions. METHODS The study included 88 patients with three neurologic conditions: 40 with cerebral palsy (CP) due to oxygen deprivation (OD), 23 with CP related to neonatal icterus (NI), and 25 with neurological sequelae after traumatic brain injury. Bone marrow aspiration was conducted from the patients' bilateral anterior iliac crest under general anesthesia in an operating theater. MNCs were isolated by Ficoll gradient centrifugation and then infused intrathecally. RESULTS There was a significant difference in the average MNC per ml and percentage of CD34+ cells by the type of disease, age group, and infusion time (p value < 0.05). The multivariable regression model showed the percentage of CD34+ association with the outcome (gross motor function 88 items- GMFM-88) in patients with CP. CONCLUSIONS The density of MNCs was 5.22 million cells per mL and 5.03% CD34+ cells in patients with three neurologic conditions. The highest density of MNCs in each ml of bone marrow was found in patients with CP due to OD, whereas the percentage of CD34+ cells was the highest among patients with CP related to NI.

Abstract
Skeletal muscle possesses a remarkable regenerative capacity, mainly relying on a population of undifferentiated and unipotent muscle progenitors, called muscle stem cells (MuSCs) or satellite cells, and their interplay with various cell types within the niche. Investigating the cellular composition of skeletal muscle tissues and the heterogeneity among various cell populations is crucial to the unbiased understanding of how cellular networks work in harmony at the population level in the context of skeletal muscle homeostasis, regeneration, aging, and diseases. As opposed to probing the average profile in a cell population, single-cell RNA-seq has unlocked access to the transcriptomic landscape characterization of individual cells in a highly parallel manner. This chapter describes the workflow for single-cell transcriptomic analysis of mononuclear cells in skeletal muscle by taking advantage of the droplet-based single-cell RNA-seq platform, Chromium Single Cell 3' solution from 10x Genomics®. Using this protocol, we can reveal insights into muscle-resident cell-type identities, which can be exploited to study the muscle stem cell niche further.

Abstract
Pyroptosis is an immunological response to infection and cellular stresses initiated by inflammasome oligomerization resulting in the release of pro-inflammatory factors including cytokines and other immune stimuli into the extracellular matrix. In order to understand the role of inflammasome activation and subsequent pyroptosis in human infection and disease pathogenesis and to explore markers of these signaling events as potential disease or response biomarkers, we must utilize quantitative, reliable, and reproducible assays to readily investigate these pathways in primary specimens. Here, we describe two methods using imaging flow cytometry for evaluation of inflammasome ASC specks in homogeneous peripheral blood monocytes and in bulk, heterogeneous peripheral blood mononuclear cells. Both methods can be applied to assess speck formation as a biomarker for inflammasome activation in primary specimens. Additionally, we describe the methods for quantification of extracellular oxidized mitochondrial DNA from primary plasma samples, serving as a proxy for pyroptosis. Collectively, these assays may be utilized to determine pyroptotic influences on viral infection and disease development or as diagnostic aids and response biomarkers.

Abstract
It is unclear whether direct-acting antiviral drugs (DAAs) result in the complete eradication of HCV infection or whether some quantities of the virus may persist after achieving a sustained virologic response (SVR). Aim The aim of this work was to study the possibility of the persistence of HCV RNA in peripheral blood mononuclear cells (PBMCs) after achieving SVR following DAA treatment. This study included 100 patients infected with HCV genotype 4, who were candidates for receiving DAAs and who achieved SVR during follow-up, as determined at 12 and/or 24 weeks following the end of treatment. All patients were subjected to demographic, biochemical and hematological assessments. Detection of HCV RNA in the serum and PBMCs and determination of the HCV genotype were performed with real-time PCR. We detected HCV RNA in the PBMCs of 20 out of 100 (20%) patients infected with HCV genotype 4, who achieved SVR. However, the persistent viral load in the PBMCs was very low (range: 400-900 U/mL; mean ± SD: 645.45 ± 153 U/mL). Multiple logistic regression analysis showed that only the higher posttreatment levels of aspartate transaminase (AST) were significantly predictive of HCV RNA persistence in the PBMCs (OR: 1.29; 95% CI: 1.08-1.55). Additionally, according to the Cox proportional hazard model, liver cirrhosis was the only significant risk factor for the persistence of HCV infection in PBMCs (HR: 5.8; 95% CI: 1.3-26.1; P < 0.02). Our results indicated the persistence of HCV RNA in some HCV patients who achieved SVR after treatment with DAAs.

Abstract
Background We aimed to determine whether NLRP3 inflammasomes in peripheral blood mononuclear cells (PBMC) were associated with carotid plaque instability in carotid atherosclerosis patients. Methods Consecutive 38 carotid atherosclerosis with vulnerable plaques, 22 carotid atherosclerosis with stable plaques, and 40 healthy subjects with no carotid or coronary artery stenosis were enrolled. They were referred to the Second Hospital of Dalian Medical University from 2013-2019. Carotid plaques were evaluated by modified plaque vulnerability risk score (MPVRS) and pathological assessment. The mRNA and protein expression of NLRP3 inflammasome components in PBMC were determined by quantitative real time PCR and Western blot analysis or ELISA. Results When consecutive study subjects undergoing carotid endarterectomy were divided into stable (≤4) and unstable (>4) plaque groups according to the MPVRS, the unstable plaque group had significantly raised mRNA and protein expression of NLRP3 inflammasome components in PBMC as compared with the stable plaque group and healthy subject group. Furthermore, subjects with higher NLRP3 protein expression in PBMC had greater incidence of cerebrovascular events. Conclusion Increased NLRP3 inflammasome components in PBMC is associated with instability of human carotid atherosclerotic plaques, suggesting NLRP3 inflammasome as a potential biomarker for monitoring carotid plaque instability.

Abstract
BACKGROUND Thymosin beta 4 × (Tmsb4x) has been highlighted as an important regulator in immune and inflammation responses. Promoted differentiation of mononuclear cells into dendritic cells (DCs) exert a beneficial effect on septicemia. Herein, we investigated the effects of Tmsb4x on the mononuclear cells to affect immune responses during septicemia. METHODS Initially, we isolated peripheral blood samples from healthy individuals and patients with septicemia for extraction of mononuclear cells, followed by Tmsb4x expression quantification. A cell model was constructed with mononuclear cells through lipopolysaccharide stimulation. The viability and apoptosis were evaluated in response to Tmsb4x silencing or re-expression. Additionally, the proportion of DCs was assessed by determining levels of inflammatory factors as well as by flow cytometric analysis. A mouse septicemia model was developed for in vivo validation. RESULTS Cell and animal models demonstrated decreased Tmsb4x expression in the setting of septicemia, which led to increased inflammatory response and reduced proportion of DCs, along with inhibited mononuclear cell viability and promoted apoptosis. However, restoration of Tmsb4x facilitated the differentiation of mononuclear cells into DCs. CONCLUSION To conclude, upregulated Tmsb4x promoted the generation of DCs from mononuclear cells, which contributed to deep understanding of underpinning mechanisms in the development of septicemia.

BACKGROUND Studies have described the role of microRNAs (miRNAs) in thymic function, along with directly observing the altered expression of miRNAs in thymuses of myasthenia gravis (MG) patients; so, miRNAs became a core component in the pathophysiology of MG. However, because the miRNA analysis results are contradictory, the identification of MG-related miRNAs is daunting. OBJECTIVE We did a systematic review of studies analyzing the miRNA expression profile of peripheral blood and mononuclear cells for patients with MG. METHODS We ran a database search in PubMed, Scopus, and Web of Science on August 17, 2021. Original articles that analyzed miRNA profiles in peripheral blood (serum, plasma, and whole blood) and peripheral blood mononuclear cells (PBMCs) for patients with MG in comparison with a non-MG or healthy control (HC) group were eligible. The quality of studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). RESULTS 26 studies were included. The quality of studies was fair (median score, 5). Among 226 different miRNAs that were deregulated in at least one study (range, 1-87), ten miRNAs were significantly deregulated in three or more studies. Five miRNAs (50%) showed the same deregulation: miR-106b-3p and miR-21-5p were consistently upregulated, and miR-20b, miR-15b, and miR-16 were consistently downregulated. Also, there were five miRNAs that were mostly upregulated, miR-150-5p, miR-146a, miR-30e-5p, and miR-338-3p, or downregulated, miR-324-3p, across studies. CONCLUSION These miRNAs contribute to different pathways, importantly neural apoptosis and autophagy, inflammation, T regulatory cell development, and T helper cell balance. Prior to being used for diagnostic and therapeutic purposes, it is required to pursue molecular mechanisms these consistently and mostly dysregulated miRNAs specifically use in the context of MG.

Abstract
The pathophysiology of Cutaneous Leishmaniasis (CL), an infection caused by Leishmania tropica (L. tropica) and Leishmania major (L. major) is primarily determined by inflammation-mediated immune cells. The immune response mainly depends on cells and molecules related to T-cells that influence susceptibility and disease development. Understanding the immunological mechanisms that cause tissue injury or lesion healing is critical for developing appropriate treatment strategies. In the present study, T-cells profile and cell-free mitochondrial DNA (CF mt-DNA) were investigated in CL patients infected with L. tropica (n = 34) and L. major (n = 2) and compared with non-infected healthy controls (n = 20). There was a significant (p<0.0001) difference between CD4+ T-cells among L. tropica and L. major CL-infected groups as compared to control while no significant difference (p = 0.8597) was found in the percentages of CD8+ T-cells. When L. tropica and L. major CL-infected individuals were compared to controls, the levels of IL-4 and expression of CF mt-DNA were significantly higher (p<0.0001). Higher levels of CF mt-DNA were detected in CL patients, irrespective of the infective Leishmania species. We proposed that the levels of CF mt-DNA and IL-4 in CL-infected individuals can be used to determine the disease progression. A better understanding of these biomarkers and evaluation of the immune responses in CL patients might benefit the development of vaccines and immunotherapies.

Abstract
INTRODUCTION The current multi-center, randomized, double-blind study was conducted among children with cerebral palsy (CP) to assess the safety and efficacy of umbilical cord blood mononuclear cell (UCB-MNC). We performed the diffusion tensor imaging to assess the changes in the white matter structure. METHODS Males and females aged 4 to 14 years old with spastic CP were included. Eligible participants were allocated in 4:1 ratio to be in the experimental or control groups; respectively. Individuals who were assigned in UCB-MNC group were tested for human leukocyte antigen (HLA) and fully-matched individuals were treated with UCB-MNCs. A single dose (5 × 106 /kg) UCB-MNCs were administered via intrathecal route in experimental group. The changes in gross motor function measure (GMFM)-66 from baseline to one year after treatment were the primary endpoints. The mean changes in modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also evaluated and compared between groups. The mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR) were the secondary endpoints. Adverse events were safety endpoint. RESULTS There were 72 included individuals (36 cases in each group). The mean GMFM-66 scores increased in experimental group; compared to baseline (+ 9.62; 95%CI: 6.75, 12.49) and control arm (β: 7.10; 95%CI: 2.08, 12.76; Cohen's d: 0.62) and mean MAS reduced in individuals treated with UCB-MNCs compared to the baseline (-0.87; 95%CI: -1.2, -0.54) and control group (β: -0.58; 95%CI: -1.18, -0.11; Cohen's d: 0.36). The mean PEDI scores and mean CP-QoL scores in two domains were higher in the experimental group compared to the control. The imaging data indicated that mean FA increased and MD decreased in participants of UCB-MNC group indicating improvements in white matter structure. Lower back pain, headaches, and irritability were the most common adverse events within 24 h of treatment that were related to lumbar puncture. No side effects were observed during follow-up. CONCLUSIONS This trial showed that intrathecal injection of UCB-MNCs were safe and effective in children with CP. TRIAL REGISTRATION The study was registered with ClinicalTrials.gov ( NCT03795974 ).

Abstract
The CITE-seq workflow combines conventional single-cell transcriptomic analysis with simultaneous analysis of cell surface protein expression using oligonucleotide-conjugated antibodies. This addition of immunophenotyping to mRNA data allows for a more detailed characterization of single-cell heterogeneity and can help to identify markers for the prospective isolation of transcriptionally defined novel cell subsets. Here, we describe the workflow for the preparation of human cord blood mononuclear cells and CD34+-enriched hematopoietic progenitors for the simultaneous characterization of protein and RNA using the commercially available TotalSeq™ antibodies from BioLegend and the droplet-based single-cell RNA-seq commercial platform from 10x Genomics.

Abstract
BACKGROUND Ligation of intersphincteric fistula tract (LIFT) is a sphincter-saving procedure used for treatment of complex anal fistula. The current study aimed to assess the outcome of local injection of bone marrow mononuclear cells (BM-MNCs) in conjunction with LIFT as compared to LIFT alone in regards to healing rate, time to healing, and ultimate success rate. METHODS This was a prospective randomized trial on patients with trans-sphincteric anal fistula. Patients were randomly allocated to one of two equal groups: LIFT and LIFT with BM-MNC injection. The main outcome measures were healing at 10 weeks of follow-up, recurrence after healing, and complications. RESULTS Seventy patients (48 male and 22 female) of a mean age of 37.9 ± 10.4 years were included. The mean time to complete healing after LIFT + BM-MNCs was significantly shorter than after LIFT alone (20.5 ± 5.2 vs 28.04 ± 5.8 days; P < 0.0001). The ultimate success rates of both groups were similar (LIFT = 60% vs LIFT with BM-MNCs = 68.6%, P = 0.62). There was no significant difference in the mean operation time or complication rate between the two groups. Secondary extension and previous anal surgery were significant independent predictors of failure of healing. CONCLUSION LIFT combined with BM-MNC injection was associated with a shorter time to complete healing than LIFT alone. However, BM-MNC injection did not have a significant impact on the overall healing and ultimate success rate.

Abstract
Background Quality and Quantity culture media (QQ culture media) was reported to enhance vasculogenesis and angiogenesis function of mononuclear cells (MNCs) from healthy volunteers. In this study, MNCs from chronic limb-threatening ischemia (CLTI) patients were cultured in QQ culture media, and then investigated for angiogenesis-related phenotype and function. Methods Patients aged ≥ 18 years with CLTI caused by atherosclerosis of the lower extremities were prospectively recruited at Siriraj Hospital (Bangkok, Thailand) during July 2017–December 2018. Peripheral blood mononuclear cells (PBMNCs) were isolated from peripheral blood. PBMNCs were cultured in either QQ culture media or standard culture media. The number of CD34+CD133+ cells, CD206+ cells, CD4+CD25+CD127+ cells, colony formation assay, and human umbilical vein endothelial cell (HUVEC) tube formation assay in MNCs were compared between those cultured in QQ culture media and those cultured in standard culture media. Results Thirty-nine patients were included with a mean age of 69 ± 11 years. Diabetes mellitus was found in 25 (64%) patients. The percentage of CD34+CD133+ progenitor cells in MNCs cultured in QQ culture media and in MNCs cultured in standard culture media was 4.91 ± 5.30% and 0.40 ± 0.46%, respectively (p < 0.0001). The percentage of CD206+ cells in MNCs cultured in QQ culture media and in MNCs cultured in standard culture media was 19.31 ± 11.42% and 4.40 ± 2.54%, respectively (p < 0.0001). The percentage of inactive population of T regulatory cells (CD4+CD25+CD127+ cells) in MNCs cultured in standard culture media and in MNCs cultured in QQ culture media was 14.5 ± 10.68% and 1.84 ± 1.37%, respectively (p < 0.0001). The total number of colony-forming units from MNCs cultured in QQ culture media and in MNCs cultured in standard culture media was 8.86 ± 8.35 of 2 × 105 cells/dish, and 0.58 ± 1.05 of 2 × 105 cells/dish, respectively (p < 0.0001). The mean intensity of Dil-Ac-LDL uptake that incorporated into the HUVEC forming tube was 1.37 ± 0.88 in MNCs cultured in QQ culture media, and 0.78 ± 0.41 in MNCs cultured in standard culture media. (p < 0.0003). Conclusions MNCs from CLTI patients that were cultured in QQ culture media had a significantly higher number of CD34+CD133+ cells and anti-inflammatory cells, and higher angiogenesis-related function compared to MNCs cultured in standard culture media.

Abstract
Background: This study aimed to analyze cultures of mononuclear (MN) cells with Giardia lamblia to determine the levels of the cytokines IFN-γ and TGF-β and the functional activity of MN cells after incubation with cytokines. Methods: This study was conducted in 2018 in Barra do Garças, Mato Grosso State, Brazil. Blood samples were collected from 60 healthy volunteer donors to obtain leukocytes. The levels of IFN-γ and TGF-β were quantified in trophozoite cell culture supernatants. Superoxide release, phagocytosis, microbicidal activity, apoptosis and intracellular calcium release were analyzed. Results: The cytokines evaluated were detected in the culture supernatant of MN cells and G. lamblia. Regardless of the type of cytokine, MN cells increased superoxide release in the presence of G. lamblia. Phagocytosis, microbicidal activity and apoptosis were higher when MN phagocytes were treated with cytokines. The highest microbicidal activity and apoptosis rates were observed in MN cells cultured with TGF-β. IFN-γ increased the release of intracellular calcium by MN phagocytes. Conclusion: Cytokines play a beneficial role in the host by activating MN cells against G. lamblia. In addition, phagocytosis causes G. lamblia death and that the modulation of the functional activity of blood MN phagocytes by cytokines is an alternative mechanism for eliminating G. lamblia.

Abstract
Background Cystic echinococcosis (CE) is a zoonotic disease caused by infection with Echinococcus granulosus. Toll-like receptors (TLRs) as the first line of defense against various parasites play a critical role in sensing and triggering anti-parasite responses. Methods The study was conducted at the Department of Pathobiology, Faculty of Veterinary Medicine, Ferdowsi University of Mashhad, Iran in 2019. Ovine peripheral blood mononuclear cells (PBMCs) were stimulated with hydatid cyst-derived antigens including hydatid cyst fluid (HCF), germinal layer antigens (GL), somatic and excretory/secretory (ES) products of protoscoleces (PSC). To investigate whether the expression of TLR2 and TLR4 was altered during exposure to these antigens, PBMCs were stimulated with two different concentrations at different time points. Results After exposure of PBMCs to ES and somatic antigens of protoscoleces (PSC) the expression of TLR2 and TLR4 was down-regulated in comparison with control group. Similarly, HCF markedly down-regulated TLR2 and TLR4 transcripts independent of dose and time. GL antigens significantly down-regulated TLR2, while TLR4 expression was up-regulated as compared with control group. Conclusion Hydatid cyst-derived antigens could dysregulate the expression of TLR2 and TLR4 in ovine PBMCs, suggesting a possible mechanism to suppress host immunity to establish chronic infection.

Abstract
Traumatic brain injury (TBI) is characterized by broad clinical symptoms in brain insult by external damages to the skull. TBI potentially leads to severe physical, cognitive, and emotional impairment. The complex biochemical reactions of inflammatory processes in TBI significantly influence brain function and clinical sequelae's overall severity. Mesenchymal stem cell therapy has become a promising therapeutic field of treatment for serious injuries due to its ability to regulate the inflammatory microenvironment. In this study, we aimed to investigate MSC's anti-inflammatory ability through regulating leukocyte, neutrophils, and inflammatory factors (IL-6, CRP, and TNF-a), thereby reducing the trauma in the TBI. Biological effects of autologous MNC and MSC cell transplantation have been studied in 40 patients with molded TBI, after being filtered according to appropriate criteria. All patients initially received MNCs and subsequently MSCs (both intravenously) followed by continuous monitoring during treatment (2 months) with clinical cognitive indicators. The results after transplantation MSC indicated that the majority of patients experienced improved health function in different degrees during the follow-up period. Lower serum levels of inflammatory factors, leukocytes, and neutrophils population were detected following the transplantation compared with the levels prior to treatment and with the control patients. No severe symptoms were observed in patients after transplantation, despite 3-4 death cases in each group. Overall, the present study suggests that transplantation of MSC possibly regulates inflammatory factors and appears to be safe in TBI treatment.

Abstract
BACKGROUND Bone marrow mononuclear cells (BM-MNCs), as a collection of hematopoietic and mesenchymal stem cells (MSCs), are capable of producing all blood cell lineages. The use of cytokines, growth factors, or cells capable of secreting these factors will help in stimulating the proliferation and differentiation of these cells into mature cell lines. On the other hand, MSCs are multipotent stromal cells that can be differentiated into various cell lineages. Moreover, these cells can control the process of hematopoiesis by secreting cytokines and growth factors. The present study aimed to investigate the effect of BM-derived MSCs on the differentiation of MNCs based on the assessment of cell surface markers by flow cytometry analysis. METHODS For this purpose, the MNCs were purified from rat BM using density gradient centrifugation. After that, they were cultured, expanded, and characterized. Next, BM-derivedMSCs were co-cultured with MNCs and then were either cultured with MNCs alone (control group) or co-cultured MNCs with BM derived-MSCs (experimental group). Finally, they were collected on day 7 and subjected to flow cytometry analysis for granulocyte markers and ERK protein's investigation. RESULTS It was found that the expression levels of CD34, CD16, CD11b, and CD18 granulocyte markers, as well as protein expression of ERK, have significantly increased in the experimental group compared to the control group. CONCLUSION Therefore, it can be concluded that MSCs could affect the granulocyte differentiation of MNCs via ERK protein expression, which is a key component of the ERK signaling pathway.

Abstract
HIV infection is a global health concern. Current HIV-diagnostics provide information about the disease progression and efficacy of anti-retroviral therapies (ARVs), but this information is very limited and sometimes imprecise. Present study assessed the potential role of mononuclear cell (MNC) death, expression of caspases (1&3) and cell free mitochondrial DNA (CF mt-DNA) in HIV infected individuals. Apoptosis, cell-count, expression of caspases and CF mt-DNA were measured through flow cytometry and qPCR, respectively, in HIV infected individuals (n = 120) divided in two groups i.e. ARVs-receiving (treated, n = 87), ART-naïve (untreated, n = 37) and healthy individuals (n = 47). Data showed significant (p < 0.0001) cell death in untreated individuals than treated and healthy individuals. CD4-positive T-cell percentage declined (p < 0.0001) in untreated as compared to treated individuals. Caspase-1, an indicator of pyroptosis, and CF mt-DNA were also elevated in untreated HIV infected individuals. Untreated individuals when administered with ARVs showed improved CD4-positive T-cell percentage, lower caspase-1, CF mt-DNA and cell death. Data elucidated positive co-relation between cell death and CF mt-DNA in treated and untreated HIV infected individuals. While CD4-positive T-cell percentage was negatively correlated with caspase-1 expression and CF mt-DNA. Elevated levels of CF mt-DNA and caspase-1 in HIV infected individuals, positive correlation between cell death and CF mt-DNA, negative correlation of CD4-positive T-cell percentage with CF mt-DNA and caspase-1 expression clearly indicated the potential of CF mt-DNA and caspase-1 as a novel disease progression and ARTs effectiveness biomarkers in HIV.

Abstract
Here we report the inhibitory effects of nine non-steroidal anti-inflammatory drugs (NSAIDs) on soybean 15-lipoxygenase (15-LOX) enzyme (EC 1.13.11.12) by three different methods; UV-absorbance, colorimetric and chemiluminescence methods. Only two drugs, Ibuprofen and Ketoprofen, exhibited enzyme inhibition by UV-absorbance method but none of the drug showed inhibition through colorimetric method. Chemiluminescence method was found highly sensitive for the identification of 15-LOX inhibitors and it was more sensitive and several fold faster than the other methods. All tested drugs showed 15-LOX-inhibition with IC50 values ranging from 3.52 ± 0.08 to 62.6 ± 2.15 µM by chemiluminescence method. Naproxen was the most active inhibitor (IC50 3.52 ± 0.08 µM) followed by Aspirin (IC50 4.62 ± 0.11 µM) and Acetaminophen (IC50 6.52 ± 0.14 µM). Ketoprofen, Diclofenac and Mefenamic acid showed moderate inhibitory profiles (IC50 24.8 ± 0.24 to 39.62 ± 0.27 µM). Piroxicam and Tenoxicam were the least active inhibitors with IC50 values of 62.6 ± 2.15 µM and 49.5 ± 1.13 µM, respectively. These findings are supported by expression analysis, molecular docking studies and density functional theory calculations. The expression analysis and flow cytometry apoptosis analysis were carried out using mononuclear cells (MNCs) which express both human 15-LOX and 5-LOX. Selected NSAIDs did not affect the cytotoxic activity of MNCs at IC50 concentrations and the cell death showed dose dependent effect. However, MNCs apoptosis increased only at the higher concentrations, demonstrating that these drugs may not induce loss of immunity in septic and other inflammatory conditions at the acceptable inhibitory concentrations. The data collectively suggests that NSAIDs not only inhibit COX enzymes as reported in the literature but soybean 15-LOX and MNCs LOXs are also inhibited at differential values. A comparison of the metabolomics studies of arachidonic acid pathway after inhibition of either COX or LOX enzymes may reconfirm these findings.

Abstract
Human cytomegalovirus (HCMV) can cause severe disease in the immunocompromised. One of the hallmarks of HCMV infection of a human host is the targeted infection of peripheral blood monocytes (but not other leukocyte populations) that in turn serve as the key cell type for hematogenous dissemination and the establishment of persistence following primary infection. Monocytes are also a key cell type associated with viral reactivation and spread following viral reactivation. Because of their importance in the HCMV-host infection cycle and lifelong infection, it is critical to be able to study their infection in controlled in vitro systems in the laboratory. In this chapter, we discuss a viable protocol for harvesting fresh ex vivo blood monocytes from human donors that are pure and unactivated cells and that can be used in a research setting.

Abstract
BACKGROUND Although there is increasing evidence showing that cell senescence is increased in circulating PBMC in type 2 diabetes mellitus (T2DM), the data are contradictory. This study examined several senescence biomarkers, including LMNA/C transcript variants, p16INK4a, p53, and p21Cip1/WAF, in PBMC of T2DM patients and the effect of Metformin on these senescence markers. METHODS Blood samples were obtained from 30 lean, 30 obese, 20 newly diagnosed type 2 diabetes mellitus (T2DM), and 30 T2DM on Metformin. PBMC were isolated and mRNA expression of the senescence biomarkers were quantified by RT-qPCR. The effect of ectopic expression of LMNA and LMNC in human monocytic cells lines (THP-1 and U937) on several inflammatory mediators were also examined. RESULTS LMNA expression was significantly higher in PBMC of obese and T2DM patients. LMNC expression was significantly inhibited in T2DM patients. LMNAΔ10 and Progerin mRNA expression was not detected in PBMC of all groups. Expression of p16INK4a, p21Cip1/WAF and p53 were inhibited significantly in T2DM. Metformin treatment reverted LMNA, LMNC, and p53 expression levels to normal levels. Upregulation of LMNA in monocytic THP-1 and U937 cell lines induced CD68, TNFα, CCL2, IL-6 and NOS2. CONCLUSIONS These data support the notion that LMNA may mediate senescence in PBMCs of T2DM by upregulating inflammatory pathways. Metformin may exert its anti-inflammatory property by modulation of senescence mediator LMNA.

Abstract
Introduction The isolation of captured peripheral blood mononuclear cells (PBMNCs) from leukoreduction filters (LRFs) can be of great importance in terms of bringing the lost cells back into use. Objective The aim of this study was to evaluate various methods based on their potential to recover the peripheral blood cells from LRFs with a focus on mononuclear cells (MNCs). Method For cell isolation from LRFs, three distinct methods (back-flushing, direct and vacuum pump) were compared through the calculation of the yield of isolated MNCs. The viability of extracted cells was determined by the flow cytometry technique. Moreover, the recovered MNCs were characterized regarding the presence of blood stem cell purification. The cell culture, microscopic observation, and immunophenotyping were employed to characterize the blood stem cells (hematopoietic, mesenchymal and progenitor endothelial stem cells). Results The yield of isolation obtained in the back-flushing, direct and vacuum pump methods were 17.7 ± 1.28, 17.3 ± 0.96 and 21.2 ± 0.90 percent, respectively. Although the highest potential for total blood cell recovery belonged to the vacuum pump method, the lowest cell viability (85.73 ± 4.84%) was observed in this method. However, the isolation process of the back-flushing and direct methods had less effect on cell viability. The characterization of the isolated MNCs displayed that the dominant positive phenotype was for CD34/CD45, indicating hematopoietic stem cells. In addition, the endothelial stem/progenitor cells were significantly detected as CD31/CD133 positive cells. Conclusion According to our results and considering the safety and efficiency potential of each of the applied methods, the back-flushing in comparison with the other methods can be considered a suitable procedure for MNC isolation from LRFs.

Abstract
Worldwide, more than 1 billion people have elevated blood pressure, with up to 45% of adults affected by the disease. In 2016 the global health study report on patients from 67 countries was released in Lancet, which identified hypertension as the world's leading cause for death and disability-adjusted years since 1990. This paper aims to analyze the pathophysiological connection between hemodynamic inflammatory reactions through sodium balance, salt sensitivity, and potential pathophysiological reactions. Besides, we explore how sodium consumption enhances the expression of transient receptor potential channel 3 (TrpC3) mRNA and facilitates the release of calcium inside immune cell groups, together with elevated blood pressure in essential hypertensive patients.

Abstract
Donor lymphocytes infusions (DLIs) are a major therapeutic approach to treat relapse and mixed chimerism after allogeneic hematopoietic cell transplant (alloHCT). The impact of the composition regarding different cell subsets in the development of graft-versus-host disease (GVHD) is not fully understood. We performed a cell subsets analysis of 56 DLIs from fully HLA-compatible identical matched sibling donors (MSDs) in 36 alloHCT patients and studied its association with GVHD. A median of one DLI was infused per patient. Fourteen patients (38%) developed GVHD. The cell composition analysis of the first DLI (DLI1) showed that a high dose of B cells (P = .03) and CD27+ B cells (P < .01) was associated with GVHD. We identified DLI dose cutoff points for several cell populations above which GVHD was more frequent (CD8+ TN >3 × 106 cells/kg, CD27+ B cells >2.6 × 106/kg, CD27+ NK >0.35 × 106 cells/kg, and mononuclear cells >0.83 × 108/kg). Noteworthy, the proportion of CD4+ naive T cells (TN) or unselected TN was not linked with GVHD and a DLI1 containing a higher dose of regulatory T cells was not protective for GVHD. We studied several transplant clinical variables and did not find any association with GVHD. Altogether, this study provides a comprehensive analysis of the cell populations in a DLI from MSDs and identifies potential key cell subsets, which provides insight for the understanding of GVHD after DLI.

Abstract
Early life stress alters the function and feedback regulation of the hypothalamic-pituitaryadrenal (HPA) axis, and can contribute to neuroinflammation and neurodegeneration by modifying peripheral blood mononuclear cell (PBMC) activity. The retina, as part of the nervous system, is sensitive to immune changes induced by stress. However, the consequences of stress experienced at an early age on retinal development have not yet been elucidated. Here we aimed to evaluate the impact of maternal separation (MatSep) across three stages of the lifespan (adolescent, adult, and aged) on the retina, as well as on progression through the cell cycle and mitochondrial activity in PBMCs from female Wistar rats. Newborn pups were separated from their mother from postnatal day (PND) 2 until PND 14 for 3 h/day. Retinal analysis from the MatSep groups showed architectural alterations such as a diminished thickness of retinal layers, as well as increased expression of proinflammatory markers DJ-1, Iba-1, and CD45 and the gliotic marker GFAP. Additionally, MatSep disrupted the cell cycle and caused long-term increases in mitochondrial activity in PBMCs from adolescent and adult rats. Changes in the cell cycle profile of the PBMCs from aged MatSep rats were undetected. However, these PBMCs exhibited increased sensitivity to H2O2-induced oxidative stress in vitro. Therefore, these results suggest that early life stress can have long-term effects on retinal structure and function, possibly elicited by neonatal immune preconditioning.

Abstract
Background Chronic Traumatic Brain Injury (TBI) is one of the common causes of longterm disability worldwide. Cell transplantation has gained attention as a prospective therapeutic option for neurotraumatic disorders like TBI. The postulated mechanism of cell transplantation which includes angiogenesis, axonal regeneration, neurogenesis and synaptic remodeling, may tackle the pathology of chronic TBI and improve overall functioning. Methods To study the effects of cell transplantation, 50 patients with chronic TBI were enrolled in an open label non-randomized study. The intervention included intrathecal transplantation of autologous bone marrow mononuclear cells and neurorehabilitation. Mean follow up duration was 22 months. Fifteen patients underwent second dose of cell transplantation, 6 months after their first intervention. Percentage analysis was performed to analyze the symptomatic improvements in the patients. Functional independence measure (FIM) was used as an outcome measure to evaluate the functional changes in the patients. Statistical tests were applied on the pre-intervention and post-intervention scores for determining the significance. Comparative Positron Emission Tomography- computed tomography (PET CT) scans were performed in 10 patients to monitor the effect of intervention on brain function. Factors such as age, multiple doses, time since injury and severity of injury were also analyzed to determine their effect on the outcome of cell transplantation. Adverse events were monitored throughout the follow up period. Results Overall 92% patients showed improvements in symptoms such as sitting and standing balance, voluntary control, memory, oromotor skills lower limb activities, ambulation, trunk & upper limb activity, speech, posture, communication, psychological status, cognition, attention and concentration, muscle tone, coordination, activities of daily living. A statistically significant (at p ≤ 0.05 with p-value 0) improvement was observed in the scores of FIM after intervention on the Wilcoxon signed rank test. Better outcome of the intervention was found in patients with mild TBI, age less than 18 years and time since injury less than 5 years. Ten patients who underwent a repeat PET CT scan brain showed improved brain metabolism in areas which correlated to the symptomatic changes. Two patients had an episode of seizures which was managed with medication. They both had an abnormal EEG before the intervention and 1 of them had previous history and was on antiepileptics. No other major adverse events were recorded. Conclusion This study demonstrates the safety and efficacy of cell transplantation in chronic TBI on long term follow up. Early intervention in younger age group of patients with mild TBI showed the best outcome in this study. In combination with neurorehabilitation, cell transplantation can enhance functional recovery and improve quality of life of patients with chronic TBI. PET CT scan brain should be explored as a monitoring tool to study the efficacy of intervention.

Abstract
Venous blood provides a ready source of large numbers of unstimulated granulocytes and mononuclear cells. Exploiting the differences in the relative densities of the leukocytes circulating in venous blood, one can separate leukocytes from erythrocytes as well as isolate the individual leukocyte populations in high purity for use in ex vivo studies. For selected functional studies, such as transcriptional analysis or cytokine quantitation, addition of an immunomagnetic negative selection step to the standard isolation protocol can yield highly purified human neutrophils.

Abstract
We investigated cellular functional and targeted immune cytokine responses of farmed Chinook salmon (Oncorhynchus tshawytscha) peripheral blood mononuclear cells (PBMCs) in vitro to LPS from Escherichia coli (E. coli) serotypes O111: B4 and O55: B5, and a phorbol ester phorbol 12-myristate 13-acetate (PMA). Bacterial LPS and PMA significantly (p < 0.05) induced reactive oxygen species (ROS) production in O. tshawytscha PBMCs, and enhanced by interferon (IFN)-inducible cytokine production. Cellular phagocytosis was significantly enhanced with PMA and E. coli serotype O111: B4 LPS after 1 and 2 h respectively. At the molecular level, LPS and PMA significantly (p < 0.05) upregulated pro-inflammatory cytokine gene transcripts for IFNγ, TNF-α, and anti-inflammatory IL-10, 24 h post-stimulation. This response is postulated to be mediated via the MyD88 and TRIF pathways in TLR4, or synergistic TLR1 and TLR2 receptors. This is the first report of LPS induced immune related in vitro responses in farmed O. tshawytscha PBMCs.

Abstract
The mechanism of action of Platelet Rich Plasma (PRP) is thought to be related to the biomolecules present in α-granules. However, for the healing process to occur, an inflammatory phase is also deemed necessary. Leukocytes present in the inflammatory phase release both pro- and anti-inflammatory molecules. The latter may play an important role in the process of "inflammatory regeneration". Thus, we propose that in the context of healing, both platelets and leukocytes play an important role, specifically due to the macrophage's plasticity to switch from the M1 to M2 fraction. Therefore, we propose that PRP products derived from the buffy coat may be more beneficial than detrimental from a standpoint of the regenerative potential of PRP.

Abstract
This study aimed to evaluate the association of CD3+, CD4+, and CD8+ T cells and tumor-infiltrating macrophages (TIMs) with the clinical parameters of female dogs harboring mammary gland tumors. Thirty female dogs affected with mammary carcinomas were used, and all tumors were histologically classified as complex carcinoma and were triple-negative phenotype determined by immunohistochemistry. Freshly frozen sections were used to determine CD3+, CD4+ and CD8+ T cells by immunohistochemistry, and TIMs were determined by immunofluorescence assays. Ten out of the 30 dogs showed lymph node metastasis at diagnosis. Fifteen dogs had a tumor of grade I (15/30), nine (9/30) had a tumor of grade II and six (6/30) had a tumor of grade III. The mean overall survival was 680.5 days (± 200.4). Dogs with sentinel lymph node positivity (10/30) (P = .0035) and dogs that developed metastasis (P = .0001) showed a shorter survival time. In addition, dogs with a high level of inflammatory infiltrate in tumor tissues presented a shorter survival time (P = .0001) than that of other dogs. Dogs with tumors containing higher numbers of CD3+ T cells (P = .001), CD4+ T cells (P = .001), or TIM cells (P < .0001) showed a shorter survival time than that of other dogs. Our results suggested that characteristics of immune cell infiltrates, including CD3+ T cells, CD4+ T cells, and TIMs, can be used as potential prognostic indicators for predicting clinical outcomes in dogs with mammary gland tumors, particularly tumors with a complex histological subtype and triple-negative phenotype.

Abstract
S100A8/A9 represents a novel biomarker and therapeutic target in sterile inflammatory diseases. Among the various S100 proteins, S100A8 and S100A9 have been shown to be the most important of all the damage-associated molecular pattern (DAMP) proteins in sterile inflammatory conditions such as diabetes, cardiovascular disease, autoimmune disorders, etc. We present here methods to quantify S100A8/A9 expression in various tissues in mouse models of myocardial infarction (MI) using flow cytometry (FC), immunofluorescence, quantitative real-time polymerase chain reaction (q-RT-PCR), and enzyme-linked immunosorbent assays (ELISA).

Abstract
BACKGROUND The role of monocyte/macrophage-derived microparticles (MPs) in the pathophysiology of cancer and chronic inflammatory diseases has been reported; nevertheless, the mechanism underlying microparticles release is currently unclear. The aim of the current study was to investigate whether matrix metalloproteinase (MMP) inhibitors could prevent MP shedding from stimulated human monocyte/macrophage. METHODS Microparticles were obtained by isolated peripheral blood mononuclear cells after stimulation with the calcium ionophore, A23187. MP shedding, intracellular calcium concentration, analysis of RhoA expression, and proteolytic activities of isolated MPs were assessed in the absence or presence of MMP inhibitors. RESULTS We demonstrated that MMP inhibitors remarkably prevented MP shedding in a concentration-dependent manner with IC50 values in the nano- to micromolar range. Such an effect was related to their ability to reduce the intracellular Ca2+ levels induced by the calcium ionophore and the consequent translocation of RhoA from cytosol to membrane. Furthermore, MMP inhibitors could inhibit the proteolytic activity of cell-derived MPs. CONCLUSIONS The current study provide evidence that MMP inhibitors can prevent MPs shedding from stimulated human monocyte/macrophage and the proteolytic activity of released MPs. Finally, the most active compound tested might represent the lead compound of a new class of molecules with therapeutic potential in cancer and chronic inflammatory diseases.

Abstract
OBJECTIVE Marsupials suffer from an increasing number of stressors in this changing world. Functional studies are thus needed to broaden our understanding of the marsupial immune system. The red-tailed phascogale (Phascogale calura) is a small Australian marsupial previously used in descriptive immunological studies. Here, we aimed to develop functional assays by isolating and stimulating blood and spleen mononuclear cells in vitro. RESULTS While peripheral blood mononuclear cell (PBMC) were relatively easy to isolate, only 105 mononuclear cells (> 90% purity and > 75% viability) could be recovered from the spleen, independently of the sex and age of the animal or the centrifugation time and speed tested. The pores of the mesh sieve used for tissue homogenization might have been too big to yield a single cell suspension. Nevertheless, in spite of the overall low number of cells recovered, PBMC and splenic mononuclear cells were successfully activated in preliminary trials with phytohemaglutinin. This activation state was evidenced by a change in shape and the presence of small cell aggregations in the mitogen-stimulated cultures. A non-radioactive colorimetric assay was also performed to confirm cell proliferation in these wells. This work highlights the importance of developing and reporting detailed methodological protocols in non-traditional research species.

Abstract
Most studies highlight mesenchymal stem cells (MSCs) extracted primarily from bone marrow (BM), very few report the use of peripheral blood (PB), often due to the associated low seeding density and difficulties with extraction techniques. As ageing populations are becoming more predominant globally, together with escalating demands for MSC transplantation and tissue regeneration, obtaining quality MSCs suitable for induced differentiation and biological therapies becomes increasingly important. In this study, BM and PB were obtained from elderly patients and extracted MSCs grown in vitro to determine their successful isolation and expansion. Patients’ socio-demographic background and other medical information were obtained from medical records. Successful and failed cultures were correlated with key demographic and medical parameters. A total of 112 samples (BM or PB) were used for this study. Of these, 50 samples (44.6%) were successfully cultured according to standardised criteria with no signs of contamination. Our comparative analyses demonstrated no statistical correlation between successful MSC cultures and any of the six demographic or medical parameters examined, including sample quantity, age, sex, race, habits and underlying comorbidities of sample donors. In conclusion, the present study demonstrates that typical demographics and comorbidities do not influence successful MSC isolation and expansion in culture.

Abstract
Background MALDI-TOF mass spectrometry (MS) on whole cells enables the detection of different cell types and cell activation. Here, we wondered whether this approach would be useful to investigate the host response in sepsis. Methods Peripheral blood mononuclear cells (PBMCs) from patients with severe sepsis and healthy donors were analyzed with MALDI-TOF MS. PBMCs from healthy donors were also stimulated with lipopolysaccharide, peptidoglycan, CpG oligonucleotides, polyinosinic polycytidylic acid, and with heat-inactivated bacteria. Averaged spectra of PBMCs stimulated in vitro by different agonists were generated from the database using the Biotyper software and matching scores between each spectrum from patients and averaged spectra from the database were calculated. Results We show that the MALDI-TOF MS signature of PBMCs from septic patients was specific, compared with healthy controls. As the fingerprints observed in patients may be related to PBMC activation, PBMCs from healthy controls were stimulated with cytokines, soluble Pathogen-Associated Molecular Patterns (PAMPs) and heat-killed bacteria, and we created a database of reference spectra. The MALDI-TOF MS profiles of PBMCs from septic patients were then compared with the database. No differences were found between patients with documented infection (n = 6) and those without bacteriological documentation (n = 6). The spectra of PBMCs from septic patients matched with those of interferon-γ- and interleukin-10-stimulated PBMCs, confirming that sepsis is characterized by both inflammatory and immunoregulatory features. Interestingly, the spectra of PBMCs from septic patients without documented infection matched with the reference spectrum of PBMCs stimulated by CpG oligonucleotides, suggesting a bacterial etiology in these patients. Conclusions Despite the limits of this preliminary study, these results indicate that the monitoring of functional status of PBMCs in peripheral blood by whole cell MALDI-TOF MS could provide unique opportunities to assess disease progression or resolution in clinical settings.

Abstract
Introduction Heart valve tissue engineering may provide improved treatment for valvular heart disease, yet development of a tissue engineered heart valve (TEHV) has been limited by incomplete recellularization of the valve leaflets. In this study, we compare the leaflet recellularization potential of candidate cell populations. Methods Four cell populations were tested: bone marrow mononuclear cells (MNC), 5 million bone marrow mesenchymal stem cells (MSC), 10 million bone marrow mesenchymal stem cells (MSC2), and 5 million valve interstitial cells (VIC). Candidate cell populations were seeded onto decellularized heart valves and underwent similar conditioning in a low-flow bioreactor for 2 weeks. Results MSC2 valves demonstrated the best recellularization of the interstitial leaflet tissue as well as an appropriate cell phenotype, mechanical properties, and biochemical composition. MSC valves exhibited similar leaflet repopulation, yet had decreased mechanical and biochemical properties. MNC seeding resulted in minimal recellularization of the leaflet, though an additional time point group found cells present after 3 days, which seemed to disappear at 2 weeks. VIC seeding resulted in cell clumping on the leaflet surface and poor recellularization. Conclusions The results of this study suggest mesenchymal stem cells are a preferred cell population for TEHV recellularization. Additionally, MSCs demonstrate the ability for repopulation of the distal valve leaflet, which will lead to more complete recellularization of future TEHVs.

Abstract
Umbilical cord blood-derived mononuclear cell (UCB-MNC) transplants improve recovery in animal spinal cord injury (SCI) models. We transplanted UCB-MNCs into 28 patients with chronic complete SCI in Hong Kong (HK) and Kunming (KM). Stemcyte Inc. donated UCB-MNCs isolated from human leukocyte antigen (HLA ≥4:6)-matched UCB units. In HK, four patients received four 4-μl injections (1.6 million cells) into dorsal entry zones above and below the injury site, and another four received 8-μl injections (3.2 million cells). The eight patients were an average of 13 years after C5-T10 SCI. Magnetic resonance diffusion tensor imaging of five patients showed white matter gaps at the injury site before treatment. Two patients had fiber bundles growing across the injury site by 12 months, and the rest had narrower white matter gaps. Motor, walking index of SCI (WISCI), and spinal cord independence measure (SCIM) scores did not change. In KM, five groups of four patients received four 4-μl (1.6 million cells), 8-μl (3.2 million cells), 16-μl injections (6.4 million cells), 6.4 million cells plus 30 mg/kg methylprednisolone (MP), or 6.4 million cells plus MP and a 6-week course of oral lithium carbonate (750 mg/day). KM patients averaged 7 years after C3-T11 SCI and received 3-6 months of intensive locomotor training. Before surgery, only two patients walked 10 m with assistance and did not need assistance for bladder or bowel management before surgery. The rest could not walk or do their bladder and bowel management without assistance. At about a year (41-87 weeks), WISCI and SCIM scores improved: 15/20 patients walked 10 m ( p = 0.001) and 12/20 did not need assistance for bladder management ( p = 0.001) or bowel management ( p = 0.002). Five patients converted from complete to incomplete (two sensory, three motor; p = 0.038) SCI. We conclude that UCB-MNC transplants and locomotor training improved WISCI and SCIM scores. We propose further clinical trials.

Abstract
Dengue envelope (E) protein is a dominant antigen for vaccine development and E-based vaccines have shown partial or full protection against live-virus challenge in non-human primates. Generally, T cell responses can be investigated with peptides. However, hundreds of over-lapping peptides need to be synthesized to cover the whole sequence of a protein, which brings the cost up to a much higher level than purchasing a protein. We have developed an enzyme-linked immunospot (ELISpot) assay that uses intact E proteins instead of peptides for assessing IFN-gamma (IFN-γ) responses. The assay relies on professional antigen presenting cells, dendritic cells, to process and present the E proteins to stimulate T cells.Peripheral blood mononuclear cells (PBMCs) from dengue-exposed and naïve subjects were selected for the assay development. IFN-γ production ranged from 53 to 513 spot forming units (SFUs) and 0-45 SFUs per million PBMCs in dengue-exposed and naive subject groups, respectively. The assay allowed quantification of E-specific IFN-γ secreting memory T cells in subjects 9 years after exposure to a live-attenuated virus vaccine and live-virus challenge. Our results suggest that the dendritic cell-based IFN-γ assay is a useful tool for assessing immunological memory for clinical research.

Abstract
Background Different cell populations from bone marrow were used in various clinical trials for cardiac diseases during last decade. Four clinical studies are ongoing in our institution and enroll patients with cardiac diseases, coronary disease, type 2 diabetes, and osteoarthritis. The density gradient is used to separate bone marrow mononuclear cells. Joint replacement procedures were associated with significant loss of tissue. Usually, excess tissue as bone marrow, peripheral blood and fat are removed to clean operation site. The aim of this study is to prove whether removed tissue during joint replacement procedure can be considered as a significant source of mononuclear cells. Methods Excised tissue obtained during joint replacement procedure was collected by AutoLog system. Bone marrow tissue was collected by iliac crest puncture. Mononuclear cells from both sources were isolated by using Ficoll density gradient centrifugation. Flow cytometry was used to detect mononuclear cell, CD34+ population counts and cell viability. Tissue processing yields between the group of joint replacement and iliac crest puncture group were compared. Results Together, 34 bone marrow tissue processings were performed. On average, samples contained 46.31 ± 9.35 ml of bone marrow solution. Average cell yield in final product was 28.64 ± 9.35 × 106 MNCs and 0.77 ± 1.51 × 106 CD34+ population. In case of tissue removed during joint replacement nine processings were performed. On average samples contained 450 ± 157.69 ml of tissue solution. Average cell yield in final product was 76.67 ± 35.42 × 106 MNCs and 1.33 ± 0.97 × 106 CD34+ population. Conclusions Tissue processing analysis shows that tissue removed during joint replacement procedure can be assumed as a significant source of mononuclear cells. Methods used for bone marrow-derived mononuclear cell extraction can be applied to the excess tissue.

Abstract
To harvest for T cell therapy, a 1.6-fold higher number of CD3+ T cells was collected with MNC mode (N = 10) compared with Auto PBSC mode (N = 5) in COBE Spectra cell separator, but the blood product volume was increased by 3.5-fold. For therapeutic angiogenesis therapy, apheresis was initially performed using Auto PBSC mode (N = 4) to fine tune the blood product volume to omit cell concentration, but the collected number of mononuclear cells was lower than expected. However, an increase of the harvest cycle number from 3.8 ± 0.5 to 7.4 ± 2.0 cycles (N = 19) resulted in a 2.1-fold higher number of collected mononuclear cells (8.7 ± 4.1 × 109 vs. 4.1 ± 1.0 × 109 cells, P < 0.05). The increase in blood product volume by this modification appeared to be lower than that expected with MNC mode. These data show that optimal harvesting can be achieved by modification of default collection settings.

Abstract
Teflon has been commonly used as a surgical material. In particular, Teflon has been considered suitable for microvascular decompression of cranial nerves, as it is a stable, inert substance that does not resorb or migrate. Giant cell foreign body reactions after microvascular decompression (MVD) have been reported, but this rare complication has not been well recognized. Here, we report one case of Teflon granuloma that occurred 4 years after MVD for hemifacial spasm. We discuss the cause, histopathological analysis, particular MVD surgical methods, and management of Teflon granuloma.

Abstract
Ovarian cancer is one of the most fatal tumors in women. Due to a lack of symptoms and adequate screening methods, patients are diagnosed at advanced stages with extensive tumor burden (Jelovac and Armstrong, 2011). Interestingly, ovarian cancer metastasis is generally found within the peritoneal cavity rather than other tissues (Lengyel, 2010; Tan et al., 2006 ). The reason behind this tissue tropism of the peritoneal cavity remains elusive. A prominent feature of this selectivity is ascites, the accumulation of fluid within the peritoneal cavity, containing, amongst others, immune cells, tumor cells and various soluble factors that can be involved in the progression of ovarian cancer ( Kipps et al., 2013 ). The protocol described here is used to isolate mononuclear cells from ascites to study the functionality of the immune system within the peritoneal cavity.

Abstract
Mononuclear cells play key roles in the pathogenic mechanisms leading to HIV-associated neurocognitive disorders (HANDs). We examined the association between HIV DNA within peripheral blood mononuclear cell (PBMC) subsets and HAND in Nigeria. PBMCs were collected at baseline from 36 antiretroviral naive participants. CD14+ cells and T&B lymphocyte fractions were isolated by, respectively, positive and negative magnetic bead separation. Total HIV DNA within CD14+ and T&B cells were separately quantified using real-time PCR assay targeting HIV LTR-gag and cell input numbers determined by CCR5 copies/sample. Utilizing demographically adjusted T scores obtained from a 7-domain neuropsychological test battery, cognitive status was determined by the global deficit score (GDS) approach, with a GDS of ≥0.5 indicating cognitive impairment. In a linear regression adjusting for plasma HIV RNA, CD4 and lymphocyte count, Beck's depression score, and years of education, there was 0.04 lower log10 HIV DNA copies within T&B lymphocytes per unit increase in global T score (p = 0.02). Adjusting for the same variables in a logistic regression, the odds of cognitive impairment were 6.2 times greater per log10 increase in HIV DNA within T&B lymphocytes (p = 0.048). The association between cognitive impairment and HIV DNA within CD14+ monocytes did not reach statistical significance. In this pretreatment cohort with mild cognitive dysfunction, we found a strong association between levels of HIV DNA within the lymphocyte subset and HAND independent of plasma HIV RNA. These findings likely reflect the neurologic impact of a larger HIV reservoir and active viral replication.

Abstract
At childbirth (parturition), zinc (Zn) homeostasis in cord blood (CB) can be affected by a number of factors: Zn in maternal blood, parturition related stress as well as metallothionein (MT). Both Zn and stress are known inducers of MT which is primarily involved in Zn homeostasis. This study analyzed Zn concentration [Zn], in CB components and MT-2A transcription in CB mononuclear cells (MNC) in relation to primiparous and multiparous childbirth. [Zn] in CB (n = 47) plasma, erythrocytes, and MNCs were measured by atomic absorption spectrophotometry (λ = 213.9 nm). The MT-2A transcription in CB-MNC was quantified using real-time PCR. Significant correlations (Pearson r) were found between: plasma-[Zn] and erythrocyte-[Zn] (p = 0.002); [Zn] and MT-2A messenger RNA (mRNA) (p = 0.000) in CB-MNC. Student's t tests showed higher levels of MT-2A mRNA and MNC-[Zn] in CB of older (≥25 years) compared to younger mothers (≤24 years) (p = 0.043 and p = 0.016, respectively). Significantly higher [Zn] was found in CB plasma (p = 0.017) and MNC (p = 0.041) of older primiparous compared to the younger primiparous and older multiparous mothers respectively. MT-2A mRNA in CB-MNC was significantly lower in CB of younger primiparous mothers compared to their older counterparts (p = 0.001). Path analysis showed that MNC-[Zn] (β = 0.83; p = 0.000) had a greater influence on MT-2A mRNA expression, compared to parity (β = -0.14; p = 0.033). Higher [Zn] in CB of primiparous mothers could be linked to higher stress during parturition, however, might be beneficial for the growth and development of the child. Together MNC-[Zn] and parity contributed ~70 % of the MT-2A transcription in CB-MNC.

Abstract
Prompted by findings suggesting immune instability in infantile bilateral striatal necrosis (IBSN), we evaluated levels of proinflammatory (tumor necrosis factor α, interleukin [IL]-1β, IL-6, interferon [IFN]γ) and anti-inflammatory (IL-10 and IL-1ra) cytokines produced by peripheral blood mononuclear cells (PBMC) from 6 children with IBSN and 11 age-matched controls. Compared to controls, non-stimulated PBMC from the IBSN group produced a significantly lower level of IL-1ra (by 38%; p < 0.001) and significantly lower levels of TNFα, IL-1β, and IFNγ (by 36% [p < 0.001], 25% [p = 0.06], and 32% [p < 0.02]) under PBMC stimulation. The severe cachexia manifesting shortly after IBSN onset may impair the immunological state, placing patients at risk of death from hyperpyrexia and sepsis.

Abstract
UNLABELLED Fluoxetine, a selective serotonin reuptake inhibitor antidepressant, modulates the mitogen-induced proliferation of lymphocytes. Lymphocytes contain taurine and express taurine transporter (TauT). Among the effects of taurine on lymphocytes are protection against oxidants and regulation of the inflammatory aspects of the immune response. Our aim was to determine the influence of fluoxetine treatment on taurine transport, and to determine the presence of TauT in the mononuclear cells of rats. METHODS Male adult Sprague-Dawley rats were treated with fluoxetine 10 mg/kg i.p. for 1, 2, and 3 weeks. The cells were obtained by density gradients. [3H]Taurine was used for transport assays. Amino acid levels were determined by high-performance liquid chromatography. Immunolabeling of CD4+, CD8+, and TauT was performed. The mRNA of TauT was evaluated by RT-PCR. Controls were included for each protocol. RESULTS The transport of taurine, after 1 week of treatment, was significantly augmented compared to controls. The affinity significantly increased at 1 and 2 weeks. While the percentage of CD4+ cells decreased and that of CD8+ cells increased, the percentage of TauT in CD4+ and CD8+ cells was not affected. Reduction of levels of aspartic acid, glutamic acid, threonine, alanine, glycine, and arginine occurred at 1 and 2 weeks. The taurine concentration significantly decreased after 2 and 3 weeks of treatment. The estimation of mRNA of TauT was not different. CONCLUSION Taurine transport increases with fluoxetine treatment, and so this could be related to an immunomodulatory role of fluoxetine through TauT. Inhibition of serotonin reuptake might be involved in the regulation of taurine transport in mononuclear cells.
