Abstract
Sjögren syndrome (SS) is an autoimmune disease in which immune cells infiltrate the exocrine gland. Since SS is caused by a disorder of the immune system, treatments should regulate the immune response. Sphingosylphosphorylcholine (SPC) is a sphingolipid that mediates cellular signaling. In immune cells, SPC has several immunomodulatory functions. Accordingly, this study verifies the immunomodulatory ability and therapeutic effect of SPC in SS. To understand the function of SPC in SS, we treated SPC in female NOD/ShiJcl (NOD) mice. The mice were monitored for 10 weeks, and inflammation in the salivary glands was checked. After SPC treatment, we detected the expression of regulatory B (Breg) cells in mouse splenocytes and the level of salivary secretion-related genes in human submandibular gland (HSG) cells. Salivary flow rate was maintained in the SPC-treated group compared to the vehicle-treated group, and inflammation in the salivary gland tissues was relieved by SPC. SPC treatment in mouse cells and HSG cells enhanced Breg cells and salivary secretion markers, respectively. This study revealed that SPC can be considered as a new therapeutic agent against SS.

Abstract
The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread to nearly every continent, registering over 1,250,000 deaths worldwide. The effects of SARS-CoV-2 on host targets remains largely limited, hampering our understanding of Coronavirus Disease 2019 (COVID-19) pathogenesis and the development of therapeutic strategies. The present study used a comprehensive untargeted metabolomic and lipidomic approach to capture the host response to SARS-CoV-2 infection. We found that several circulating lipids acted as potential biomarkers, such as phosphatidylcholine 14:0_22:6 (area under the curve (AUC) = 0.96), phosphatidylcholine 16:1_22:6 (AUC = 0.97), and phosphatidylethanolamine 18:1_20:4 (AUC = 0.94). Furthermore, triglycerides and free fatty acids, especially arachidonic acid (AUC = 0.99) and oleic acid (AUC = 0.98), were well correlated to the severity of the disease. An untargeted analysis of non-critical COVID-19 patients identified a strong alteration of lipids and a perturbation of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, aminoacyl-tRNA degradation, arachidonic acid metabolism, and the tricarboxylic acid (TCA) cycle. The severity of the disease was characterized by the activation of gluconeogenesis and the metabolism of porphyrins, which play a crucial role in the progress of the infection. In addition, our study provided further evidence for considering phospholipase A2 (PLA2) activity as a potential key factor in the pathogenesis of COVID-19 and a possible therapeutic target. To date, the present study provides the largest untargeted metabolomics and lipidomics analysis of plasma from COVID-19 patients and control groups, identifying new mechanisms associated with the host response to COVID-19, potential plasma biomarkers, and therapeutic targets.

Abstract
Lysophosphatidylcholines are a group of bioactive lipids heavily investigated in the context of inflammation and atherosclerosis development. While present in plasma during physiological conditions, their concentration can drastically increase in certain inflammatory states. Lysophosphatidylcholines are widely regarded as potent pro-inflammatory and deleterious mediators, but an increasing number of more recent studies show multiple beneficial properties under various pathological conditions. Many of the discrepancies in the published studies are due to the investigation of different species or mixtures of lysophatidylcholines and the use of supra-physiological concentrations in the absence of serum or other carrier proteins. Furthermore, interpretation of the results is complicated by the rapid metabolism of lysophosphatidylcholine (LPC) in cells and tissues to pro-inflammatory lysophosphatidic acid. Interestingly, most of the recent studies, in contrast to older studies, found lower LPC plasma levels associated with unfavorable disease outcomes. Being the most abundant lysophospholipid in plasma, it is of utmost importance to understand its physiological functions and shed light on the discordant literature connected to its research. LPCs should be recognized as important homeostatic mediators involved in all stages of vascular inflammation. In this review, we want to point out potential pro- and anti-inflammatory activities of lysophospholipids in the vascular system and highlight recent discoveries about the effect of lysophosphatidylcholines on immune cells at the endothelial vascular interface. We will also look at their potential clinical application as biomarkers.

Abstract
Sphingosylphosphorylcholine (SPC) is a unique type of lysosphingolipid found in some diseases, and has been studied in cardiovascular, neurological, and inflammatory phenomena. In particular, SPC’s studies on cancer have been conducted mainly in terms of effects on cancer cells, and relatively little consideration has been given to aspects of tumor microenvironment. This review summarizes the effects of SPC on cancer and tumor microenvironment, and presents the results and prospects of modulators that regulate the various actions of SPC.

Abstract
In the field of orofacial surgery, a red blood cell transfusion (RBCT) is occasionally required during double jaw and oral cancer surgery. However, the question remains whether the effect of RBCT during the perioperative period is beneficial or harmful. The answer to this question remains challenging. In the field of orofacial surgery, transfusion is performed for the purpose of oxygen transfer to hypoxic tissues and plasma volume expansion when there is bleeding. However, there are various risks, such as infectious complications (viral and bacterial), transfusion-related acute lung injury, ABO and non-ABO associated hemolytic transfusion reactions, febrile non-hemolytic transfusion reactions, transfusion associated graft-versus-host disease, transfusion associated circulatory overload, and hypersensitivity transfusion reaction including anaphylaxis and transfusion-related immune-modulation. Many studies and guidelines have suggested RBCT is considered when hemoglobin levels recorded are 7 g/dL for general patients and 8-9 g/dL for patients with cardiovascular disease or hemodynamically unstable patients. However, RBCT is occasionally an essential treatment during surgeries and it is often required in emergency cases. We need to comprehensively consider postoperative bleeding, different clinical situations, the level of intra- and postoperative patient monitoring, and various problems that may arise from a transfusion, in the perspective of patient safety. Since orofacial surgery has an especially high risk of bleeding due to the complex structures involved and the extensive vascular distribution, measures to prevent bleeding should be taken and the conditions for a transfusion should be optimized and appropriate in order to promote patient safety.

Abstract
Blood product transfusion may exacerbate the initial immunosuppressive response of sepsis. Nurses and other patient care providers must be diligent in recognizing and managing a worsening immune status, using flow cytometry to monitor patients' immune status. This type of monitoring may be instrumental in reducing morbidity and mortality in persons with sepsis. This article discusses the recent literature on the associated inflammatory responses that occur with blood transfusion and provides an analysis of alterations in key inflammatory pathways in response to transfusion in a sepsis population.

Abstract
Blood and blood-component therapy triggers immunological reactions in recipients. Transfusion-related immunomodulation [TRIM] is an important complex biological immune reaction to transfusion culminating in immunosuppression. The mechanisms underlying TRIM include the presence of residual leukocytes and apoptotic cells, the transfusion of immunosuppressive cytokines either present in donor components or generated during blood processing, the transfer of metabolically active growth factor-loaded microparticles and extracellular vesicles and the presence of free hemoglobin or extracellular vesicle-bound hemoglobin. TRIM variables include donor-specific factors as well as processing variables. TRIM may explain, at least in part, the controversial negative clinical outcomes observed in cancer patients receiving transfusion in the context of curative-intent surgeries. The use of novel technologies including metabolomics and proteomics on stored blood may pave the way for a deeper understanding of TRIM in general and its impact on cancer progression.

Abstract
Over the past 30 years, it has been demonstrated that removal of white blood cells from blood components is effective in preventing some adverse reactions such as febrile non-haemolytic transfusion reactions, immunisation against human leucocyte antigens and human platelet antigens, and transmission of cytomegalovirus. In this review we discuss indications for leucoreduction and classify them into three categories: evidence-based indications for which the clinical efficacy is proven, indications based on the analysis of observational clinical studies with very consistent results and indications for which the clinical efficacy is partial or unproven.

Oxidized lipids and lysophosphatidylcholine induce the chemotaxis, up-regulate the expression of CCR9 and CXCR4 and abrogate the release of IL-6 in human monocytes. Toxins (Basel) 2014; 6:2840-56.

Abstract
Lipids through regulation of chronic inflammation play key roles in the development of various diseases. Here, we report that a mixed population of human primary monocytes migrated towards LPC, as well as oxidized linoleic acid isoforms 9-S-HODE, 9-R-HODE and 13-R-HODE. Incubation with 9-R-HODE, 13-R-HODE and LPC resulted in increased expression of CXCR4, the receptor for SDF-1α/CXCL12, correlated with increased monocyte migration towards SDF-1α/CXCL12. Further, we report increased expression of CCR9, the receptor for TECK/CCL25, after stimulation with these lipids. Upon examining the migratory response towards TECK/CCL25, it was observed that an increase in CCR9 expression upon pre-treatment with 9-S-HODE, 9-R-HODE, 13-R-HODE and LPC resulted in increased migration of monocytes expressing CCR9. Only LPC but not any other lipid examined increased the influx of intracellular Ca2+ in monocytes. Finally, 9-S-HODE, 9-R-HODE, 13-R-HODE, or LPC inhibited the release of IL-6 from monocytes suggesting that these lipids may play important role in controlling inflammatory responses.

Abstract
Debate on appropriate triggers for transfusion of allogeneic blood products and their effects on short- and long-term survival in surgical and critically ill patients continue with no definitive evidence or decisive resolution. Although transfusion-related immune modulation (TRIM) is well established, its influence on immune competence in the recipient and its effects on cancer recurrence after a curative resection remains controversial. An association between perioperative transfusion of allogeneic blood products and risk for recurrence has been shown in colorectal cancer in randomized trials; whether the same is true for other types of cancer remains to be determined. This article focuses on the laboratory, animal, and clinical evidence to date on the mechanistic understanding of inflammatory and immune-modulatory effects of blood products and their significance for recurrence in the cancer surgical patient.

Abstract
We previously reported that human NK cells express G2A and they respond to LPC. Here, we report that oxidized lipids such as 9-R-HODE, 9-S-HODE and 13-R-HODE, as well as LPC induced the in vitro chemotaxis of human NK cells, although with variable efficacies. The chemotactic effects of these lipids were inhibited by prior treatment of NK cells with pertussis toxin (PTX). 9-S-HODE, 9-R-HODE and LPC optimally induced the influx of intracellular Ca(2+) in NK cells. Addition of 9-S-HODE prior to the addition of LPC inhibited more than 50% of the effect of LPC, whereas addition of LPC prior to the addition of 9-S-HODE completely inhibited the effect of the latter lipid. Also, there was a complete reciprocal desensitization among 9-R-HODE and LPC on the influx of intracellular Ca(2+). Further analysis showed that the four lipids did not affect NK cell lysis of tumor target cells. 9-R-HODE but not any other lipid increased the percentages of NK cells producing IFN-γ and is the only lipid that enhanced the release of this cytokine by these cells. In conclusion, we provide novel evidence showing that oxidized lipids and LPC exert important functions for cells of innate immune system.

Abstract
HMBOX1 is a new member of homeobox family and predicted to be a transcriptional repressor, its function in NK cells is completely unclear. Previously we found that overexpression of HMBOX1 downregulated mRNA level of IFN-γ in NK cells during our gene screening work. In present study, we investigate the relationship between HMBOX1 and IFN-γ in detail. Firstly, we describe the properties of HMBOX1 gene transcription in activated NK cells, and found that the transcriptional levels of HMBOX1 were significantly decreased in NK cells after activated by IL-2, IL-15 and IL-12, which was opposite to the expression profile of IFN-γ. Subsequently, over-expression of HMBOX1 significantly inhibited the expression and production of IFN-γ in NK cells in response to the stimulation of tumor cell K562 or PMA/ionomycin. Additionally, by luciferase reporter assay, HMBOX1 displayed suppressive effect on the transcription activity of IFN-γ promoter. These findings indicated that HMBOX1 may function as a negative regulator of IFN-γ in NK cells.

Abstract
Sphingosylphosphorylcholine (SPC) is a component of high-density lipoprotein particles. We investigated the functional role of SPC in HUVECs. SPC stimulation induced production of the CCL2 chemokine in a PTX-sensitive G-protein-dependent manner. SPC treatment caused the activation of NF-κB and AP-1, which are essential for SPC-induced CCL2 production, and induced the activation of three MAPKs, ERK, p38 MAPK, and JNK. Inhibition of p38 MAPK or JNK by specific inhibitors caused a dramatic decrease in SPC-induced CCL2 production. The Jak/STAT3 pathway was also activated upon SPC stimulation of HUVECs. Pretreatment with a Jak inhibitor blocked not only SPC-induced p38 MAPK and JNK activation, but also NF-κB and AP-1 activation. Our results suggest that SPC stimulates HUVECs, resulting in Jak/STAT3-, NF-κB-, and AP-1-mediated CCL2 production. We also observed that SPC stimulated expression of the adhesion molecule ICAM-1 in HUVECs. Our results suggest that SPC may contribute to atherosclerosis; therefore, SPC and its unidentified target receptor offer a starting point for the development of a treatment for atherosclerosis.

Platelet-activating factor receptor plays a role in lung injury and death caused by Influenza A in mice. PLoS Pathog 2010; 6:e1001171.

Abstract
Influenza A virus causes annual epidemics which affect millions of people
worldwide. A recent Influenza pandemic brought new awareness over the health
impact of the disease. It is thought that a severe inflammatory response against
the virus contributes to disease severity and death. Therefore, modulating the
effects of inflammatory mediators may represent a new therapy against Influenza
infection. Platelet activating factor (PAF) receptor (PAFR) deficient mice were
used to evaluate the role of the gene in a model of experimental infection with
Influenza A/WSN/33 H1N1 or a reassortant Influenza A H3N1 subtype. The following
parameters were evaluated: lethality, cell recruitment to the airways, lung
pathology, viral titers and cytokine levels in lungs. The PAFR antagonist
PCA4248 was also used after the onset of flu symptoms. Absence or antagonism of
PAFR caused significant protection against flu-associated lethality and lung
injury. Protection was correlated with decreased neutrophil recruitment, lung
edema, vascular permeability and injury. There was no increase of viral load and
greater recruitment of NK1.1+ cells. Antibody responses were
similar in WT and PAFR-deficient mice and animals were protected from
re-infection. Influenza infection induces the enzyme that synthesizes PAF,
lyso-PAF acetyltransferase, an effect linked to activation of TLR7/8. Therefore,
it is suggested that PAFR is a disease-associated gene and plays an important
role in driving neutrophil influx and lung damage after infection of mice with
two subtypes of Influenza A. Further studies should investigate whether
targeting PAFR may be useful to reduce lung pathology associated with Influenza
A virus infection in humans. Influenza virus causes disease that affects people from different age, gender or
social conditions. The illness spreads easily and affects millions of people
every year. Vaccines are effective preventive approaches, but the high degree of
viral antigenic drift requires annual formulation. Anti-viral drugs are used as
therapy, but are only effective at the very early stages of disease. The main
symptoms that lead to hospitalizations and deaths are associated with the severe
inflammatory host immune response triggered by the virus infection. Our approach
was to decrease the inflammatory events associated with the viral infection by
targeting a molecule, Platelet Activating Factor receptor (PAFR), known to
induce several inflammatory events, including leukocyte recruitment and leakage.
We found that PAFR deficient mice or wild type mice treated with a PAFR
antagonist had less pulmonary inflammation, pulmonary injury and lethality rates
when infected by two subtypes of Influenza A virus. In contrast, the immune
response against the virus, as assessed by viral loads and specific antibodies,
were not decreased. Our findings concur with the idea that severe inflammation
plays an important role in flu morbidity and mortality and show that PAFR is a
major driver of the exacerbated inflammation in mice infected with Influenza A
virus.

Abstract
Freshly isolated untreated NK cells undergo rapid apoptosis and lose their cytotoxic function upon the addition of F(ab')2 fragment of anti-CD16 antibodies. Loss of NK cell cytotoxic function after treatment with F(ab')2 fragment of anti-CD16 antibody can be seen against K562 and UCLA-2 oral tumor cells when either added immediately in the co-cultures of NK cells with the tumor cells or after pre-treatment of NK cells with the antibody before their addition to the tumor cells. Addition of Interleukin-2 (IL-2) in combination with anti-CD16 antibody to NK cells delayed the induction of DNA fragmentation in NK cells, and even though decreased cytotoxicity could still be observed against K562 and UCLA-2 oral tumors when compared to IL-2 alone treated NK cells, the cytotoxicity levels remained relatively higher and approached those obtained by untreated NK cells in the absence of antibody treatment. No increases in IFN-gamma, Granzymes A and B, Perforin and TRAIL genes could be seen in NK cells treated with anti-CD16 antibody. Neither secretion of IFN-gamma nor increased expression of CD69 activation antigen could be observed after the treatment of NK cells with anti-CD16 antibody. Furthermore, IL-2 mediated increase in CD69 surface antigens was down-modulated by anti-CD16 antibody. Finally, the addition of anti-CD16 antibody to co-cultures of NK cells with tumor target cells was not inhibitory for the secretion of VEGF by oral tumor cells, unlike those co-cultured with untreated or IL-2 treated NK cells. Thus, binding and triggering of CD16 receptor on NK cells may enhance oral tumor survival and growth by decreased ability of NK cells to suppress VEGF secretion or induce tumor cell death during the interaction of NK cells with oral tumor cells.

Abstract
Compared with other lysophospholipid mediators such as sphingosine-1-phosphate and lysophosphatidic acid, little is known about the physiological significance of the related bioactive lysosphingolipid sphingosylphosphorylcholine (SPC), which is present in high-density lipoprotein particles. The present study was undertaken to evaluate the effect of SPC on human immature dendritic cells (DCs). Reverse transcription-polymerase chain reaction and flow cytometry assays revealed that DCs express two putative receptors for SPC, ovarian cancer G-protein-coupled receptor 1 and G-protein-coupled receptor 4. Exposure to SPC induced a rapid and transient increase in intracellular free calcium concentrations but did not stimulate endocytosis or chemotaxis of DCs. SPC increased the expression of HLA-DR, CD86 and CD83 and improved the T-cell priming ability of DCs, as well as the ability of DCs to stimulate the production of interferon-gamma by allogeneic peripheral blood mononuclear cells during the mixed lymphocyte reaction. Consistent with these results, we also observed that SPC stimulated the production of interleukin (IL)-12 and IL-18 by DCs. Taken together, our results support the notion that the accumulation of SPC in peripheral tissues during the course of inflammatory processes may favour the development of T helper type 1 immunity.

Abstract
Natural killer (NK) cells express killer cell
inhibitory receptors (KIRs) that recognize polymorphic class I MHC
molecules. In the present study, we analyze the modulatory effect
of IL-2 alone or a combination of IL-12 with IL-18 on surface
expression of killer cell immunoglobulin-like receptors KIR2DL1,
KIR2DL2, and KIR3DL2 in NK cells. Thus, it was found that IL-2
causes a significant increase in the proportion of cells with
given studied receptors. Stimulation by a mixture of IL-12 and
IL-18 caused significant increase in the fraction of cells with
the KIR2DL1 and KIR2DL2, however no significant change in the
percentage of cells with KIR3DL2 receptor on their surface was
observed. The results of the study show the presence of KIRs
on both resting and activated NK cells, this may suggest that KIRs
have also an important role in the regulatory processes after
activation of this subpopulation of cells.

Abstract
AIM To investigate the effects of sphingosylphosphorylcholine (SPC) on human monocyte-derived dendritic cell (DC) chemotaxis. METHODS Human DC were generated from peripheral blood monocytes by culturing them with granulocyte macrophage-colony stimulating factor and interleukin-4. The effect of SPC on the DC chemotactic migration was measured by chemotaxis assay. Intracellular signaling event involved in the SPC-induced DC chemotaxis was investigated with several inhibitors for specific kinase. The expression of the SPC receptors was examined by reverse transcription polymerase chain reaction. RESULTS We found that SPC induced chemotactic migration in immature DC (iDC) and mature DC (mDC). In terms of SPC-induced signaling events, mitogen activated protein kinase activation and Akt activation in iDC and mDC were stimulated. SPC-induced chemotaxis was mediated by extracellular signal-regulated protein kinase and phosphoino-sitide-3-kinase, but not by calcium in both iDC and mDC. Although mDC express ovarian cancer G protein-coupled receptor 1, but not G protein-coupled receptor 4, iDC do not express any of these receptors. To examine the involvement of sphingosine-1-phosphate (S1P) receptors, we checked the effect of an S1P receptor antagonist (VPC23019) on SPC-induced DC chemotaxis. VPC23019 did not affect SPC-induced DC chemotaxis. CONCLUSION The results suggest that SPC may play a role in regulating DC trafficking during phagocytosis and the T cell-stimulating phase, and the unique SPC receptor, which is different from S1P receptors, is involved in SPC-induced chemotaxis.

Abstract
Down-modulation of CD16 (FcgammaRIII) receptors and loss of natural killer (NK) cell function have been observed in oral cancer patients. However, neither the mechanisms nor the significance of the decrease in CD16 receptors have been fully understood. The cytotoxic activity and survival of NK cells are negatively regulated by antibodies directed against CD16 surface receptor. The addition of anti-CD94 antibody in combination with either F(ab')(2) fragment or intact anti-CD16 antibody to NK cells resulted in significant inhibition of NK cell cytotoxic function and induction of apoptosis in resting human peripheral blood NK cells. Addition of interleukin-2 to anti-CD16 and/or anti-CD94 antibody-treated NK cells significantly inhibited apoptosis and increased the function of NK cells. There was a significant increase in tumor necrosis factor-alpha (TNF-alpha) but not IFN-gamma secretion in NK cells treated either with anti-CD16 antibody alone or in combination with anti-CD94 antibodies. Consequently, the addition of anti-TNF-alpha antibody partially inhibited apoptosis of NK cells mediated by the combination of anti-CD94 and anti-CD16 antibodies. Increase in apoptotic death of NK cells also correlated with an increase in type 2 inflammatory cytokines and in the induction of chemokines. Thus, we conclude that binding of antibodies to CD16 and CD94 NK cell receptors induces death of the NK cells and signals for the release of chemokines.

These cells perform two prominent functions: the first is recognizing and destroying virally infected cells and transformed cells; the second is secreting various cytokines that shape up the innate and adaptive immune re-sponses. For these cells to perform these activities, they express different sets of receptors. The receptors used by NK cells to extravasate into sites of injury belong to the seven transmembrane (7TM) family of receptors, which characteristically bind heterotrimeric G proteins. These receptors allow NK cells to sense the chemotactic gradients and activate second messengers, which aid NK cells in polarizing and migrating toward the sites of injured tissues. In addition, these receptors determine how and why human resting NK cells are mainly found in the bloodstream, whereas activated NK cells extravasate into inflammatory sites. Receptors for chemokines and lysophospholipids belong to the 7TM family. On the other hand, NK cells recognize invading or transformed cells through another set of receptors that belong to the single transmembrane-spanning domain family. These receptors are either inhibitory or activating. Inhibitory receptors contain the immune receptor tyrosine-based inhibitory motif, and activating receptors belong to either those that associate with adaptor molecules containing the immune receptor tyrosine-based activating motif (ITAM) or those that associate with adaptor molecules containing motifs other than ITAM. This article will describe the nature of these receptors and examine the intracellular signaling pathways induced in NK cells after ligating both types of receptors. These pathways are crucial for NK cell biology, development, and functions.
