Abstract
Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes a disease (coronavirus disease 2019, COVID-19) that may develop into a systemic disease with immunosuppression and death in its severe form. Myeloid-derived suppressive cells (MDSCs) are inhibitory cells that contribute to immunosuppression in patients with cancer and infection. Increased levels of MDSCs have been found in COVID-19 patients, although their role in the pathogenesis of severe COVID-19 has not been clarified. For this reason, we raised the question whether MDSCs could be useful in the follow-up of patients with severe COVID-19 in the intensive care unit (ICU). Thus, we monitored the immunological cells, including MDSCs, in 80 patients admitted into the ICU. After 1, 2, and 3 weeks, we examined for a possible association with mortality (40 patients). Although the basal levels of circulating MDSCs did not discriminate between the two groups of patients, the last measurement before the endpoint (death or ICU discharge) showed that patients discharged alive from the ICU had lower levels of granulocytic MDSCs (G-MDSCs), higher levels of activated lymphocytes, and lower levels of exhausted lymphocytes compared with patients who had a bad evolution (death). In conclusion, a steady increase of G-MDSCs during the follow-up of patients with severe COVID-19 was found in those who eventually died.

Abstract
Innate lymphoid cells (ILCs) are lymphoid cells that have important effector and regulatory functions in innate immunity and tissue remodeling. Uncontrolled activation and proliferation of ILCs can contribute to inflammatory autoimmune diseases. Behcet's disease (BD) is a complex systemic inflammatory disorder of unknown etiology. It has been shown that natural killer (NK) cells may play an immunoregulatory role in BD, however the role of ILCs is unknown. In this study, the levels and functions of ILCs and NK cell subsets in BD patients were investigated. Cell surface and cytotoxic granules (perforin and granzyme) expression of NK cells and ILCs were evaluated and labeled according to whole blood lysing protocol in peripheral blood samples obtained from the patients and healthy subjects. Cytokine levels of NK cells were investigated in stimulated peripheral blood mononuclear cells. All data were analyzed by flow cytometry. Total ILC and ILC3+ cells were increased in active BD patients compared to inactive BD patients and healthy subjects. There was no significant difference between the patients and healthy subjects regarding NK cell surface and intracellular molecule expression. Although, an increase in IFN-γ and IL-17, and a decrease in IL-4 levels were observed in CD56dim NK cell subset of BD patients. Recent studies showed increased neutrophilic infiltration and IL-17 secreting Th17 cells in BD patients. It is known that ILC3+cells are similar to Th17 subset regarding their cytokine profile and transcription factor expression patterns. Results of current study may suggest that inflammatory microenvironment in BD patients might direct ILC cells to differentiate into ILC3+ subset, and IL-17 released by NK cells might have a role in neutrophilic infiltration.

Abstract
Artemisinin (ART) has been shown to suppress B cell activation and plasma cell formation. However, its effect on splenic marginal zone (MZ) B cells is unknown. Splenic MZ B cells play a critical role in rapidly induced Ab production against blood-borne foreign Ags. Dysfunction of MZ B cells, due to inhibition of its proliferation or displacement of its homing, results in an attenuated adaptive humoral response. Here, we investigate the effect of ART on splenic MZ B (CD19+ CD21high CD23low ) and B10 (CD19+ CD1dhigh CD5+ ) B cells to explore the mechanisms of ART-induced immunosuppression in T cell-deficient nude mice challenged with hamster xenoantigens. In this study, we demonstrate that ART decreases T cell-independent xenogeneic IgM Ab production and, this is associated with a strong suppression of MZ B cell proliferation and a relative increase of CD21low CD23+ follicular and B10 B cells. In addition, this suppression impairs IL-10 production. Taken together, our data indicate that ART suppresses B cell immune responses through a distinctive effect on splenic MZ B and other B cells. This represents a new mechanism of ART-induced immunosuppression.

Abstract
Extensive studies have characterized the development and differentiation of murine B cells in secondary lymphoid organs. Antibodies secreted by B cells have been isolated and developed into well-established therapeutics. Validation of murine B cell development, in the context of autoimmune prone mice, or in mice with modified immune systems, is a crucial component of developing or testing therapeutic agents in mice and is an appropriate use of flow cytometry. Well established B cell flow cytometric parameters can be used to evaluate B cell development in the murine peritoneum, bone marrow, and spleen, but a number of best practices must be adhered to. In addition, flow cytometric analysis of B cell compartments should also complement additional readouts of B cell development. Data generated using this technique can further our understanding of wild type, autoimmune prone mouse models as well as humanized mice that can be used to generate antibody or antibody-like molecules as therapeutics.

Abstract
INTRODUCTION Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread widely. The aim of this study was to investigate the dynamic changes in peripheral blood lymphocyte subsets in adult patients with COVID-19. METHODS The electronic medical records were reviewed. Data including demographic characteristics, clinical manifestations, comorbidities, laboratory data, and radiological examinations of 435 hospitalized COVID-19 patients with a confirmed SARS-CoV-2 viral infection were extracted and analyzed retrospectively. Lymphocyte subset counts at each week after the onset of the illness were compared with those of the other weeks of illness and with those of control individuals. RESULTS The various lymphocyte subsets (CD3+, CD4+, CD8+, CD19+, and CD16/56+) were below the normal ranges at 1 week after the onset of illness, reaching a nadir during the second week. They increased gradually during the third week and returned to normal levels in the fifth week, but were still lower than those of the healthy controls. The CD3+, CD4+, and CD8+ counts were significantly lower in patients with severe disease compared to those with non-severe disease, and in patients who died compared to those who recovered. DISCUSSION This research indicates that the levels of peripheral blood lymphocyte subsets (CD3+, CD4+, and CD8+) are associated with disease progression and severity, and with the prognosis in patients with COVID-19. Dynamic monitoring of human immune function is one of the indicators for evaluating the severity of disease and the prognosis of COVID-19 patients, and is useful for formulating appropriate treatment strategies.

Abstract
Placenta-derived mesenchymal stromal cells (MSC) have attracted more attention for their immune modulatory properties and poor immunogenicity, which makes them suitable for allogeneic transplantation. Although MSC isolated from different areas of the placenta share several features, they also present significant biological differences, which might point to distinct clinical applications. Hence, we compared cells from full term placenta distinguishing them on the basis of their origin, either maternal or fetal. We used cells developed by Pluristem LTD: PLacenta expanded mesenchymal-like adherent stromal cells (PLX), maternal-derived cells (PLX-PAD), fetal-derived cells (PLX-R18), and amniotic membrane-derived MSC (hAMSC). We compared immune modulatory properties evaluating effects on T-lymphocyte proliferation, expression of cytotoxicity markers, T-helper and T-regulatory cell polarization, and monocyte differentiation toward antigen presenting cells (APC). Furthermore, we investigated cell immunogenicity. We show that MSCs and MSC-like cells from both fetal and maternal sources present immune modulatory properties versus lymphoid (T cells) and myeloid (APC) cells, whereby fetal-derived cells (PLX-R18 and hAMSC) have a stronger capacity to modulate immune cell proliferation and differentiation. Our results emphasize the importance of understanding the cell origin and characteristics in order to obtain a desired result, such as modulation of the inflammatory response that is critical in fostering regenerative processes.

Abstract
BACKGROUND Platelet apheresis is a technique in which whole blood is collected from a donor followed by platelet (PLT) separation. Platelet apheresis has a significant impact on some biochemical indices after donation. This study aimed to investigate the impact of platelet apheresis on complete blood count (CBC) and lymphocyte subsets over a typical interdonation interval. METHODS Healthy male subjects (n = 10) were recruited to study changes in CBC and lymphocyte subsets before and at three intervals following platelet apheresis. Repeated measures ANOVA was used to compare quantitative variables between different visits. RESULTS Following platelet apheresis, platelet count decreased 30% at 24 hours after donation (p < 0.001) compared to the baseline count with significant repeated ANOVA across different visits (p < 0.001, Eta = 0.558). No changes were observed in other variables of CBC. The lymphocyte subsets including CD4, CD8, and CD4/CD8 ratio were decreased at 24 hours after donation (-0.6%, -0.4% and -0.7%, respectively) but none was significant. At 24 hours, the proportion of CD19 and CD16-56 were slightly increased (1.6%, 3.3%, p > 0.05, respectively). CONCLUSIONS The significant reduction in PLT count after 24 hours of plateletpheresis may have adverse health effects on PLT donors. Platelet apheresis has no significant effect on lymphocyte subsets of the donor.

Abstract
The impact of performing exercise on the immune system presents contrasting effects on health when performed at different intensities. In addition, the consequences of performing chronic exercise have not been sufficiently studied in contrast to the effects of acute bouts of exercise. The porpoise of this work was to determine the effect that a popular exercise regimen (chronic/moderate/aerobic exercise) has on the proportion of different immune cell subsets, their function and if it affects the cannabinoid system with potentially functional implications on the immune system. A marked increase in several immune cell subsets and their expression of cannabinoid receptors was expected, as well as an enhanced proliferative and cytotoxic activity by total splenocytes in exercised animals. For this study male Wistar rats performed treadmill running 5 times a week for a period of 10 weeks, at moderate intensity. Our results showed a significant decrease in lymphocyte subpopulations (CD4+, Tγδ, and CD45 RA+ cells) and an increase in the cannabinoid receptors expression in those same cell. Although functional assays did not reveal any variation in total immunoglobulin production or NK cells cytotoxic activity, proliferative capability of total splenocytes increased in trained rats. Our results further support the notion that exercise affects the immunological system and extends the description of underlying mechanisms mediating such effects. Altogether, our results contribute to the understanding of the benefits of exercise on the practitioner´s general health.

Abstract
The discovery of innate lymphoid cells (ILC) has profoundly influenced the understanding of innate and adaptive immune crosstalk in health and disease. ILC and T cells share developmental and functional characteristics such as the lineage-specifying transcription factors and effector cytokines, but importantly ILC do not display rearranged antigen-specific receptors. Similar to T cells ILC are subdivided into 3 different helper-like subtypes, namely ILC1-3, and a killer-like subtype comprising natural killer (NK) cells. Increasing evidence supports the physiological relevance of ILC, e.g., in wound healing and defense against parasites, as well as their pathogenic role in allergy, inflammatory bowel diseases or psoriasis. Group 2 ILC have been attributed to the pathogenesis of allergic diseases like asthma and atopic dermatitis. Other inflammatory skin diseases such as allergic contact dermatitis are profoundly shaped by inflammatory NK cells. This article reviews the role of ILC in allergic skin diseases with a major focus on ILC2. While group 2 ILC are suggested to contribute to the pathogenesis of type 2 dominated inflammation as seen in atopic dermatitis, we have shown that lack of ILC2 in type 1 dominated contact hypersensitivity results in enhanced inflammation, suggesting a regulatory role of ILC2 in this context. We provide a concept of how ILC2 may influence context dependent the mutual counterbalance between type I and type II immune responses in allergic skin diseases.

Abstract
Adoptive transfer of ex vivo expanded tumor infiltrating lymphocytes (TILs) has led to clinical benefit in some patients with melanoma but has not demonstrated convincing efficacy in other solid cancers. Whilst the presence of TILs in many types of cancer is often associated with better clinical prognosis, their function has not been systematically evaluated across cancer types. Responses to immunological checkpoint inhibitors in a wide range of cancers, including those for which adoptive transfer of expanded TILs has not shown clinical benefit, has clearly delineated a number of tumor type associated with tumor-reactive lymphocytes capable of effecting tumor remissions. Neuroblastoma is an aggressive childhood solid cancer in which immunotherapy with GD2-directed antibodies confers a proven survival advantage through incompletely understood mechanisms. We therefore evaluated the feasibility of ex vivo expansion of TILs from freshly resected neuroblastoma tumors and the potential therapeutic utility of TIL expansions. TILs were successfully expanded from both tumor biopsies or resections. Significant numbers of NKT and γδT cells were identified alongside the mixed population of cytotoxic (CD8+) and helper (CD4+) T cells of both effector and central memory phenotypes. Isolated TILs were broadly non-reactive against autologous tumor and neuroblastoma cell lines, so enhancement of neuroblastoma killing was attained by transducing TILs with a second-generation chimeric antigen receptor (CAR) targeting GD2. CAR-TILs demonstrated antigen-specific cytotoxicity against tumor cell lines. This study is the first to show reproducible expansion of TILs from pediatric neuroblastoma, the high proportion of innate-like lymphocytes, and the feasibility to use CAR-TILs therapeutically.

Abstract
Objective To investigate the value of serum interleukin-6 (IL-6) and soluble interleukin-6 receptor (sIL-6R) levels of breast cancer patients in evaluating immune function after radiotherapy. Methods We randomly selected 55 cases of breast cancer patients who had received radiotherapy as an observation group, and 55 cases of normal healthy adults as a control group. ELISA was used to detect serum IL-6 and sIL-6R levels. Flow cytometry was used to detect CD45+CD19+ B lymphocytes, CD45+CD3+CD4+ T lymphocytes, CD45+CD3+CD8+ T lymphocytes and CD45+CD16+CD56+ NK cells in peripheral blood. The correlation of lymphocyte subsets with IL-6 or sIL-6R levels was analyzed. Results Serum IL-6 and sIL-6R levels of the observation group patients after radiotherapy were significantly higher than those before radiotherapy and in the control group, and the IL-6 and sIL-6R levels of patients of III or IV stage breast cancer increased significantly. Flow cytometry showed that the ratios of total T lymphocytes and NK cells in the observation group after radiotherapy were significantly reduced, while the ratio of B lymphocytes was significantly elevated. In addition, the levels of IL-6 and sIL-6R were positively correlated with the ratio of NK cells and negatively correlated with the ratio of B lymphocytes. Conclusion Serum IL-6 and sIL-6R levels in patients with breast cancer can be used as references for assessing the course of breast cancer and immune function after radiotherapy.

Abstract
Multiple myeloma (MM) is characterized by clonal proliferation of plasma cells (PCs) in the bone marrow (BM) leading to end organ damage. Recent interests are increasingly focusing on the quantitative and functional profiles of T-cell subsets, natural killer cells (NK) and natural killer T-cells (NK T), due to their importance in the development of MM. Herein we tried to evaluate the frequency of different lymphocyte subsets and cPCs in newly diagnosed MM patients and their impact on survival. This prospective case-control study included 40 newly diagnosed MM patients presented to South Egypt Cancer Institute (SECI), Assiut University and 20 apparently healthy controls. Flow cytometry was used for evaluation of CD4+ T helper cells, CD8+ T cytotoxic cells, natural NK cells, NK T cells and cPCs. CD4+ T helper cells were significantly decreased in MM patients while, cytotoxic CD8+ T cells were significantly increased in comparison to the controls leading to a significant decrease in the CD4+/CD8+ ratio in MM patients. In addition, MM patients had deficiency in NK cells and NK-T cells. The median number of cPCs was 8 (range: 0 - 477) per 50,000 cells in the MM patients. The median OS for those with < 8 cPCs was 22.5 months compared with 18 months for patients with ≥8 cPCs. In conclusion, alterations in the immune cells homeostasis in MM patients could play a role in the development of MM and may be associated with the release of plasma cells in the peripheral blood. Also, the quantitative estimation of cPCs in patients with newly diagnosed MM may be used as a predictor of survival.

Abstract
This study aimed to investigate the relationship between sleep disorders and lymphocyte subsets and cytokines in patients with lung cancer undergoing radiotherapy, and to establish a theoretical foundation for predicting sleep disorders and preventing interventions in radiotherapy in lung cancer patients. Ninety-two patients with lung cancer requiring radiotherapy were selected as the study subjects. The patients' demographic data and disease-related conditions were investigated. Their quality of sleep was measured before radiotherapy, after two and four weeks of radiotherapy, and at the end of radiotherapy. According to the Pittsburgh Sleep Quality Index Number Table (PSQI), patients with PSQI score> 7 points were put into a sleep disorder group, and patients with PSQI score 0-7 were put into a normal sleep group. Lymphocyte subsets were enumerated and cytokine levels (IL-6, IL-1b) were measured during these four periods. The difference in sleep disorders at four weeks between patients with or without synchronous chemotherapy was statistically significant (P less than 0.05). The levels of lymphocyte subsets in the sleep disorder group and the control sleep group showed no difference in the index of lymphocyte subsets before radiotherapy. In the sleep disorder group, CD4+ cells were lower after two weeks of radiotherapy (P less than 0.05). After four weeks of radiotherapy, CD3+, CD4+, and CD16+56+ subsets were lower (P less than 0.05). At the end of radiotherapy, there was no difference in each index. There was no significant difference in IL-6 levels between the two groups before radiotherapy, after two weeks, or after four weeks (P greater than 0.05). At the end of radiotherapy, IL-6 levels in the sleep disorder group were higher than those in the control sleep group (P less than 0.05). There was no significant difference in IL-1b between the two groups (P greater than 0.05). In conclusion, monitoring of T-lymphocyte subsets and IL-6 levels in patients is enhanced during radiotherapy. Clinically effective programs of radiotherapy for lung cancer improve the body's immune status.

Abstract
Group 2 innate lymphoid cells (ILC2) are innate immune cells that respond rapidly to their environment through soluble inflammatory mediators and cell-to-cell interactions. As tissue-resident sentinels, ILC2 help orchestrate localized type 2 immune responses. These ILC2-driven type 2 responses are now recognized in diverse immune processes, different anatomical locations, and homeostatic or pathological settings. ILC2-derived cytokines and cell surface signaling molecules function as key regulators of innate and adaptive immunity. Conversely, ILC2 are governed by their environment. As such, ILC2 form an important nexus of the immune system and may present an attractive target for immune modulation in disease.

Abstract
Understanding the pathways and regulation of human haematopoiesis, in particular, lymphopoiesis, is vital to manipulation of these processes for therapeutic purposes. However, although haematopoiesis has been extensively characterised in mice, translation of these findings to human biology remains rudimentary. Here, we describe the isolation of three progenitor subsets from human foetal bone marrow that represent differential stages of commitment to the natural killer (NK) cell lineage based on IL-15 responsiveness. We identify CD7 as a marker of IL-15 responsive progenitors in human bone marrow and find that this expression is maintained throughout commitment and maturation. Within the CD7+ fraction, we focussed on the lineage potential of three subsets based on CD127 and CD117 expression and observed restricted lymphoid and biased NK cell potential amongst subsets. We further demonstrate the presence of subsets similar in both phenotype and function in umbilical cord blood and the bone marrow of humanised mice, validating these as appropriate sources of progenitors for the investigation of human haematopoiesis. Overall, we describe several stages in the process of lymphopoiesis that will form the basis of investigating the regulators of this process in humans.

Abstract
A hallmark of acute hepatic injury is the recruitment of neutrophils, monocytes and lymphocytes, including natural killer (NK) or T cells, towards areas of inflammation. The recruitment of leukocytes from their reservoirs bone marrow or spleen into the liver is directed by chemokines such as CCL2 (for monocytes) and CCL5 (for lymphocytes). We herein elucidated the impact of chemokine receptor inhibition by the dual CCR2 and CCR5 inhibitor cenicriviroc (CVC) on the composition of myeloid and lymphoid immune cell populations in acute liver injury. CVC treatment effectively inhibited the migration of bone marrow monocytes and splenic lymphocytes (NK, CD4 T-cells) towards CCL2 or CCL5 in vitro. When liver injury was induced by an intraperitoneal injection of carbon tetrachloride (CCl4) in mice, followed by repetitive oral application of CVC, flow cytometric and unbiased t-SNE analysis of intrahepatic leukocytes demonstrated that dual CCR2/CCR5 inhibition in vivo significantly decreased numbers of monocyte derived macrophages in acutely injured livers. CVC also reduced numbers of Kupffer cells (KC) or monocyte derived macrophages with a KC-like phenotype, respectively, after injury. In contrast to the inhibitory effects in vitro, CVC had no impact on the composition of hepatic lymphoid cell populations in vivo. Effective inhibition of monocyte recruitment was associated with reduced inflammatory macrophage markers and moderately ameliorated hepatic necroses at 36h after CCl4. In conclusion, dual CCR2/CCR5 inhibition primarily translates into reduced monocyte recruitment in acute liver injury in vivo, suggesting that this strategy will be effective in reducing inflammatory macrophages in conditions of liver disease.

Abstract
Flow cytometry has become a basic of biological research and clinical diagnostics, and its application has been crucial to numerous advances in immunology and cell biology. However, several issues remain when considering intracellular stainings, especially in the context of a daily routine use and in multicenter clinical research protocols including large cohorts of patients. The requirements for multiple protocol steps are not only time-consuming but also frequently associated with high cell loss and nonspecific binding or reduced fluorescence. These drawbacks make standardized intracellular flow cytometry use in multicenter studies struggling. As a consequence, intracellular flow cytometry has mostly remained a tool for experimental and clinical research. In the current chapter, we will complete flow cytometry protocols described in the previous edition by presenting novel intracellular protocols usable in clinic. These present with many advantages including shorter time-to-results, one-step whole blood procedures, lyse-no-wash-no-centrifuge protocols, improved staining quality, and lyophilized coated reagents in ready-to-use tubes. This opens novel perspectives for standardization and feasibility in clinical studies, for drug efficacy monitoring and for patients' stratification within a context of personalized medicine. Here, we present illustrative examples taken from septic patients' immunomonitoring. We consider the evaluation of myeloperoxidase and lactoferrin expressions in neutrophils, FOXP3 lymphocyte expression, and STAT5 phosphorylation in lymphocyte subsets.

Abstract
BACKGROUND Reference ranges for adult peripheral blood lymphocyte subsets have been established in a few countries. To the best of our knowledge no broad lymphocyte subset analysis of the Israeli population has been reported. Objectives: To establish reference ranges for healthy adults in Israel and to describe age- and gender-specific differences, if present. OBJECTIVES To establish reference ranges for healthy adults in Israel and to describe age- and gender-specific differences, if present. METHODS Lymphocyte subsets CD3, CD3/CD4, CD3/CD8, CD3-/CD16+/CD56+, CD3/TCRαβ, CD3/TCRγδ, and CD19 were examined by flow cytometry in 326 subjects. Samples were subdivided according to age and gender. RESULTS Women of all ages had a significantly higher percentage and absolute counts of CD3/CD4 cells than their male counterparts. Higher CD3/CD4 cells were observed also in the older population (> 50 years). CD3/CD8 and CD3-/CD16+/CD56+ were higher in males. Older males had a lower total lymphocyte percentage and CD19 cells compared to younger men. No significant gender-related differences were observed in percent and number of CD19, CD3/TCRαβ or CD3/TCRγδ at all ages. CONCLUSIONS These reference values could be useful in further studies for assessing changes that occur in different populations in human pathology.

Abstract
Chronic stress generally experienced in our daily lives; is known to augment disease vulnerability by suppressing the host immune system. In the present study; the effect of modified Aloe polysaccharide (MAP) on chronic stress-induced immunosuppression was studied; this Aloe compound was characterized in our earlier study. Mice were orally administered with MAP for 24 days and exposed to electric foot shock (EFS; duration; 3 min; interval; 10 s; intensity; 2 mA) for 17 days. The stress-related immunosuppression and restorative effect of MAP were then analyzed by measuring various immunological parameters. MAP treatment alleviated lymphoid atrophy and body weight loss. The numbers of lymphocyte subsets were significantly normalized in MAP-treated mice. Oral administration of MAP also restored the proliferative activities of lymphocytes; ovalbumin (OVA)-specific T cell proliferation; antibody production; and the cell killing activity of cytotoxic T lymphocytes. In summary; oral administration of MAP ameliorated chronic EFS stress-induced immunosuppression.

Abstract
OBJECTIVE To analyze the characteristics of lymphocyte phenotypes in hepatitis B virus (HBV) transgenic mice and the effect of exogenous interferon-α on virological profiles and lymphocytes phenotypes of the mice. METHODS HBV transgenic mice and wild-type (WT) mice were examined for serum levels of HBsAg, HBcAb, IL-21, and IL-6 using ELISA. The frequencies of CD4(+)T and CD19(+)B cells separated from the liver, spleen, and peripheral blood were detected by flow cytometry. Nine HBV transgenic mice were injected subcutaneously with recombinant mouse interferon alpha (rmIFN-α) and another 9 transgenic mice were injected with PBS, and their HBsAg, HBV DNA, IL-6, and IL-21 levels and frequencies of peripheral blood CD4(+)T and CD19(+)B cells were detected. RESULTS HBV transgenic mice showed a high level of HBsAg with a detectable level of HBcAb and significantly increased serum levels of IL-21 and IL-6 as compared with WT mice (P<0.05). The transgenic mice had a significantly lower frequency of CD4(+) T cells in the peripheral blood, liver and spleen (P<0.05) but a significantly higher frequency of CD19(+) B cells in the liver (P<0.05). An inverse correlation between intrahepatic CD4(+) T cell frequency and serum HBsAg level while a positive correlation between intrahepatic CD19(+) B cell frequency and HBcAb level were found in HBV transgenic mice. Administration of rmIFN-α significantly increased the frequencies of CD4(+) T and CD19(+) B cells in the peripheral blood and the serum level of IL-6 in HBV transgenic mice (P<0.05). CONCLUSION HBV transgenic mice have lymphocyte subset dysregulation and exogenous interferon-α can modulate the immune function of the mice by regulating the frequencies of lymphocyte subsets.

Abstract
All lymphocytes are thought to develop from common lymphoid progenitors (CLPs). However, lymphoid-primed multipotent progenitors (LMPPs) are more efficient than CLPs in differentiating into T cells and group 2 innate lymphoid cells (ILC2s). Here, we have divided LMPPs into CD127(-) (LMPP-s) and CD127(+) (LMPP+s) subsets and compared them with Ly6D(-) and Ly6D(+) CLPs. Adult LMPP+s differentiated into T cells and ILCs more rapidly and efficiently than other progenitors in transplantation assays. The development of T cells and ILC2s is highly active in the neonatal period. Neonatal CLPs are rare and, unlike prominent neonatal LMPP+s, do not efficiently differentiate into T cells and ILC2s. ILC2s generated in the neonatal period are long lived and persist in adult tissues. These results suggest that some ILCs and T cells may develop from LMPP+s via CLP-independent pathways.

Abstract
OBJECTIVE To establish an assay using 9-color flow cytometry immunophenotyping to detect activation and apoptosis of human TCR Vβ lymphocyte subpopulations in peripheral blood samples. METHODS We used 5 antibodies (CD3, CD4, CD8, CD95, CD69), phospholipids binding proteins Annexin V, TCR Vβ Repertoire Kit and nucleus dye DAPI to establish a 9-color flow cytometry assay. Peripheral blood samples were taken from eight healthy people for test of antibodies and determination of optimal PMT and staining method (single-stained vs stained with all but one antibody). RESULTS Appropriate detecting voltage, antibody concentration and compensation methods were determined. The distribution of TCR Vβ subgroup in our samples was consistent with the TCR Vβ Repertoire Kit instruction and other published literature. CONCLUSION We have established a effective easy using 9-color flow cytometry immunophenotyping to detect human TCR Vβ lymphocyte subpopulations in peripheral blood samples.

Abstract
The local immune response is important to consider when the aim is to improve bone regeneration. Recently T lymphocytes and their associated cytokines have been identified as regulators in fracture callus formation, but it is not known whether T cells affect bone progenitor cells directly. The goal of this in vitro study was to investigate the role of different T cell subsets and their secreted factors on the osteogenic differentiation of human mesenchymal stem cells (MSCs). Significant increases in the alkaline phosphatase activity and the subsequent matrix mineralization by MSCs were found after their exposure to activated T cells or activated T cell-derived conditioned medium. Blocking IFN-γ in the conditioned medium abolished its pro-osteogenic effect, while blocking TGF-β further enhanced osteogenesis. The relative contribution of an anti- or proinflammatory T cell phenotype in MSC osteogenic differentiation was studied next. Enrichment of the fraction of anti-inflammatory regulatory T cells had no beneficial osteogenic effect. In contrast, soluble factors derived from enriched T helper 17 cells upregulated the expression of osteogenic markers by MSCs. IL-17A, and IL-17F, their main proinflammatory cytokines, similarly exhibited strong osteogenic effects when exposed directly to MSCs. IL-17A in particular showed a synergistic action together with bone morphogenetic protein 2. These results indicate that individual T cell subsets, following their activation, affect osteoblast maturation in a different manner through the production of soluble factors. From all T cells, the proinflammatory T cells, including the T helper 17 cells, are most stimulatory for osteogenesis.

Abstract
The transcription factor GATA-3 is indispensable for the development of all innate lymphoid cells (ILCs) that express the interleukin 7 receptor α-chain (IL-7Rα). However, the function of low GATA-3 expression in committed group 3 ILCs (ILC3 cells) has not been identified. We found that GATA-3 regulated the homeostasis of ILC3 cells by controlling IL-7Rα expression. In addition, GATA-3 served a critical function in the development of the NKp46(+) ILC3 subset by regulating the balance between the transcription factors T-bet and RORγt. Among NKp46(+) ILC3 cells, although GATA-3 positively regulated genes specific to the NKp46(+) ILC3 subset, it negatively regulated genes specific to lymphoid tissue-inducer (LTi) or LTi-like ILC3 cells. Furthermore, GATA-3 was required for IL-22 production in both ILC3 subsets. Thus, despite its low expression, GATA-3 was critical for the homeostasis, development and function of ILC3 subsets.

Abstract
The skin constitutes the interface between the organism and the environment, and it protects the body from harmful substances in the environment via physical, chemical and immunological barriers. The immunological barrier of the skin comprises both cells from the innate and the adaptive immune system. During the last years, it has become clear that innate lymphoid cells play a role in homeostasis and inflammation of the skin in humans and mice. In this review, we will discuss the role of innate lymphoid cells in healthy and inflamed skin with special focus on their role in atopic dermatitis.

Abstract
Management of patient care and interpretation of research data require evaluation of laboratory results in the context of reference data from populations with known health status to adequately diagnose disease or make a physiological assessment. Few studies have addressed the diversity of lymphocyte subsets in rural and urban Ugandan populations. Here, 663 healthy blood bank donors from semi-urban centers of Kampala consented to participate in a study to define lymphocyte reference ranges. Whole blood immunophenotyping was performed to determine the frequency and absolute counts of T, B, and NK cells using clinical flow cytometry. Results from blood bank donors were compared to a rural cohort from the district of Kayunga and more urban clinical trial participants from the capital city, Kampala. Relationships between hematological and lymphocyte parameters were also explored. In the semi-urban blood donors, females were significantly different from males in all parameters except the frequency of CD8 T and B cells. Females had higher absolute counts of CD4 T, CD8 T and B cells, whereas males had higher NK cell counts. NK cell frequency and counts were significantly higher in semi-urban blood donors, regardless of sex, compared to more urban study participants. CD8 T cell frequency and counts were significantly higher in the blood donors compared to the rural participants, irrespective of sex. Interestingly, basophil counts were positively associated with overall T cell counts. These findings suggest that both sex and level of cohort urbanicity may influence lymphocyte subset distributions in Ugandans.

Abstract
BACKGROUND Natural killer (NK) cells are important in destroying tumor cells. However, they are damaged by radiation therapy. We studied the effects of single and fractionated irradiation on the viability and cytotoxicity of human non-selected NK cells and sub-groups with cluster of differentiation (CD) CD16(+) and CD56(+) in vitro. Only very few studies dealing with the standard radiobiological parameters for characterizing NK cells exist in the literature. MATERIALS AND METHODS NK cell populations were isolated from buffy coats using different methods and irradiated with single doses up to 80 Gy and fractionated doses of 10 or 30 Gy with different numbers of applications and at different intervals. The study end-points were viability using propidium iodide (PI), trypan blue and intracellular adenosine triphosphate (ATP) assays, and cytotoxicity using the (51)Cr-release assay. The standard radiobiological parameters α and β of the linear-quadratic (L-Q) model and the mean inactivation dose D̅ taken as the area under the curve (AUC) were calculated to characterize the radiosensitivity of different NK cell populations. RESULTS The AUC values of the 51Cr release data in the dose range of 0-40 Gy were as follows: for non-selected NK cells, 23.6-20.9 Gy; for CD16(+) and CD56(+) cells, 14.5-13.2 Gy. The AUC values of ATP, trypan blue and propidium iodide methods equally well described the viability of irradiated NK cells. The α/β ratio for cytotoxicity and viability data in the L-Q model corresponded to the acutely responding tissues. Splitting a 30-Gy dose into two fractions applied at different intervals caused a significant rise in ATP levels and cytotoxicity. Dividing the total dose into four doses applied at fixed intervals also resulted in significant elevations of ATP content and cytotoxicity of NK cells at 10 Gy. CONCLUSION According to the L-Q method, irradiated NK cells behaved similarly to acutely responding human tissues with respect to cytotoxicity and viability. The AUC proved very useful for comparing the effects of irradiation on NK cells.

Abstract
In health, long-lived plasma cells (LLPC) are essential for durable protective humoral immunity, and, conversely, in disease are a major source of pathogenic Abs in autoimmunity, graft rejection, and allergy. However, the molecular basis for their longevity is largely unknown. We have recently found that CD28 signaling in plasma cells (PC) is essential for sustaining Ab titers, by supporting the survival of LLPC, but not short-lived PC (SLPC). We now find that, unlike SLPC, CD28 activation in LLPC induces prosurvival downstream Vav signaling. Knockin mice with CD28 cytoplasmic tail mutations that abrogate Vav signaling (CD28-AYAA) had significantly fewer LLPC but unaffected SLPC numbers, whereas mice with mutations that abrogate PI3K signaling (CD28-Y170F) were indistinguishable from wild-type controls. This was consistent with the loss of CD28's prosurvival effect in LLPC from CD28-AYAA, but not CD28-Y170F, mice. Furthermore, the CD28 Vav motif in the B lineage was essential for the long-term maintenance of Ag-specific LLPC populations and Ab titers in vivo. Signaling downstream of the CD28 Vav motif induced previously undescribed transcriptional regulation of B lymphocyte-induced maturation protein-1, a key mediator of PC differentiation and maintenance. These findings suggest CD28 signaling in LLPC modulates the central B lymphocyte-induced maturation protein-1 transcriptional nexus involved in long-term survival and function.

Abstract
Age-related frailty is characterized by increased vulnerability to stress due to decline in homeostatic reserve, which results in increased risk of adverse health outcomes including disability, hospitalization, and death. The relationship between frailty and immunological system alterations is well established. Thus, analysis of immunological changes, such as alterations in lymphocyte subsets, during senescence may provide useful markers for frailty and associated pathologies. Since reference ranges currently used for lymphocyte subsets do not specifically differentiate the elderly group, the aim of this study was to (1) establish reference ranges in nonfrail elderly individuals and (2) assess the evolution of these parameters with age. Further, the influence of other physiological and lifestyle factors was also evaluated. The study was performed on 144 elderly individuals (aged 65-95) from Galicia (in northwestern Spain). Percentages of lymphocyte subpopulations (CD3(+) T lymphocytes, CD4(+) T-helper lymphocytes, CD8(+) T-cytotoxic lymphocytes, CD19(+) B lymphocytes, and CD56(+)16(+) natural killer cells) were analyzed in peripheral blood by flow cytometry, and reference ranges were calculated. The individual status as nonfrail or prefrail did not markedly affect the immunological parameters, but an apparent influence of age was obtained for %CD3(+), %CD4(+), and %CD19(+) cells, all of which fell with increasing age. Women showed higher levels of %CD19(+) lymphocytes. No significant influence of smoking habits, physical activity, or drinking alcohol or caffeine beverages was observed. The results obtained may serve as a basis to establish comparisons between frail and nonfrail elderly individuals, in order to determine the usefulness of lymphocyte subsets as immunological biomarkers of frailty.

Abstract
Recent studies have identified novel lymphocyte subsets named innate lymphoid cells (ILCs) lacking antigen-specific receptors. ILCs are present in a wide variety of epithelial compartments and occupy an intermediate position between acquired immune cells and myeloid cells. ILCs are now classified into three groups: group 1 ILC, group 2 ILC, and group 3 ILC based on their cytokine production patterns that correspond to the helper T cell subsets Th1, Th2, and Th17, respectively. ILCs play important roles in protection against various invading microbes including multicellular parasites, and in the maintenance of homeostasis and repair of epithelial layers. Excessive activation of ILCs, however, leads to various inflammatory disease conditions. ILCs have thus attracted interests of many researchers in the fields of infectious immunity, inflammatory diseases, and allergic diseases. Because epithelial cells sense alterations in environmental cues, it is important to understand the functional interaction between epithelial cells, ILCs, and environmental factors such as commensal microbiota. We discuss in this review developmental pathways of ILCs, their functions, and contribution of commensal microbiota to the differentiation and function of ILCs.

Abstract
Immunophenotyping of blood lymphocyte subsets and activation markers is a basic tool in the diagnostic process of primary immunodeficiency diseases, its use becoming more and more widespread as the knowledge about these illnesses increases. However, the availability of reliable reference values, which need to be age-matched for the pediatric population, is a pre-requisite for the reliable interpretation of immunophenotyping data. Aim of this study is to analyze the lymphocyte subsets and activation markers distribution in children aged 0-18 years referring to the University Hospital of Padova and to create age-matched reference values expressed by percentiles, thus providing a valuable guideline for the interpretation of the immunophenotype.

Abstract
A 4-year-old boy with hypochondroplasia was admitted to our clinic with complaints of bronchopneumonia. He also had immune deficiency characterized by low CD3, CD4 T-lymphocyte subsets and a low level of serum immunoglobulin A (IgA). The diagnosis of hypochondroplasia was made on clinical, radiological, and laboratory findings by the pediatric endocrinology department. The focus of our study is hypochondroplasia associated with immune deficiency which was unpublished in English medical literature previously.

Abstract
THE AIM OF STUDY Assessment of changes in lymphocyte number and some indicators of the immune suppression (frequency of regulatory T cells (Treg), the level of expression of CTLA-4 (cytolytic T lymphocyte-associated antigen 4) and interleukin (IL)-10) in patients with acute pancreatitis (AP). MATERIALS AND METHODS Peripheral blood samples of 21 patients with AP (including 11 patients with pancreatic necrosis (PN)) were studied for analysis of lymphocyte subsets and 11 blood samples of healthy donors were estimated as control. Evaluation of the expression of molecules of lymphocytes was carried out by flow cytometry. RESULTS It was found that percentage of CD3+ T cells and their subpopulation of CD4+ T-helper cells in patients with AP were decreased as compared to the control group. Substantial changes were observed in patients with PN: together with decrease in the number of T cells, CD19+ B cells and CD4+ CD25+ activated T-helper cells were also reduced, and the percentage of CD8+ T cells was higher. The immunoregulatory index (CD4+/CD8+) was lower in the group of patients, than in control group. The frequency of Treg cells (CD4+ CD25hi and CD4+ CD25+ CD127lo) was higher in patients with AP than in the control. The expression level of the inhibitory molecule CTLA-4 in the subset of CD4+ CD25hi Treg cells in patients with AP was also increased. Moreover, it was found that the expression level of anti-inflammatory cytokine IL-10 was higher in T-helper cells from patients with AP. CONCLUSION Changes in cellular immunity (especially patients with PN) werefound in patients wish AP. These changes may indicate the possible development of secondary immunodeficiency. This is probably related to the generation of immune suppression, since the values of the investigated parameters (frequency of Treg cells, the expression of CTLA-4 and IL-10) in patients with AP were higher than in controls.

Abstract
The measurement of cell-mediated immunity (CMI) is critical to understanding the role and regulation of avian lymphocytes following avian influenza virus (AIV) infection. While these different cell types have distinctly different modes of action in terms of contributions to protection, they account for the majority of adaptive immunity induced following infection or vaccination. Although the ability to measure CMI has steadily improved over the last few years, few studies have examined its role in protection of birds against AIV. The increasing availability of monoclonal antibodies recognizing various avian cell-associated antigens has made this technique more specific and informative.

Abstract
Different vitamin B12 and folic acid concentrations could exacerbate the immune response. The aim was to evaluate different dietary folic acid and vitamin B12 levels on the immune response in aged rats. Male Sprague Dawley aged rats were assigned to three folic acid groups (deficient, control, supplemented) each in absence of vitamin B12 for 30 days. Several parameters of innate and acquired immune responses were measured. Serum and hepatic folate levels increased according to folic acid dietary level, while vitamin B12 levels decreased. There was a significant decrease in natural killer cell-mediated cytotoxicity in the spleen for the vitamin B12 deficient diet and folic acid control diet groups. Significant changes in CD45 lymphocyte subsets were also observed according to dietary imbalance. Lymphoproliferative response to concanavalin A and phytohemagglutinin did not differ significantly between groups. The spleen response to lipopolysaccharide increased significantly, but was unmodified for the other organs. An imbalance between dietary vitamin B12 and folic acid concentrations alters some immunological parameters in aged rats. Therefore, the ratio between folate and vitamin B12 could be as important as their absolute dietary concentrations.

Abstract
Pre-analytical enrichment of cell populations prior to therapeutic delivery is of paramount interest throughout the fields of regenerative medicine and clinical interventional therapies. Enrichment of a cell population typically involves two aspects: (a) the increase in concentration of particular subpopulation of the total cell fraction by means of removal of other cells of no interest to the particular interrogation; and (b) improvement of resolution of signal by removal of 'noise' mostly arising from cellular debris in the treated sample. In this research, leukocyte populations were obtained from erythrocyte-depleted primary whole blood from human adults and subjected to flow through acoustic fields within the ultrasound range to remove cellular debris. It was possible to demonstrate aggregation and holding of leukocytes by using ultrasound within the frequency range 11.448-11.483 MHz, which facilitated removal of cellular debris by washing under continuous perfusion. The T-lymphocyte population were phenotypically characterized using CD4/CD8 (T(h)/T(c)) immunocytochemistry by flow cytometry and demonstrated a significant decrease in 'false-positive' events during cellular analysis, due to the efficient eradication of non-specifically reactive cells and tissue debris from the cell populations of interest. Therefore, it was possible to conclude that flow through an ultrasonic acoustic system was capable of providing a non-destructive method for the hyper-purification of primary derived cell populations, with potential exploitations throughout the fields of cellular research, medical diagnostics and clinical therapies.

Abstract
Approaches using reduced conditioning regimens have been developed to obtain minimal procedure-related toxicity. Such novel therapeutic options are being explored with good preliminary results concerning feasibility and engraftment. However, many aspects remain under-evaluated and few data are available about immune and dendritic cell (DC) reconstitution after these highly immunosuppressive regimens. We present here our data in 20 patients receiving allogeneic bone marrow transplantation (allo-BMT) using a reduced preparative regimen. We evaluated in the first 3 months following allo-BMT, several immunological parameters including DC subsets, and compared these to historical results obtained in a group of myeloablative allo-BMT patients. We found an early recovery of leukocytes, CD8+ and NK lymphocytes. We also found a trend towards an improved B cell recovery. These results are somewhat in contrast to the altered immune recovery observed in the myeloablative setting. In addition, we found a significant early circulating DC recovery. Circulating blood DCs were also found to be of full donor origin as assessed by FISH in sex-mismatched pairs. Nevertheless, naive CD4 + CD45RA + T cells were found to be profoundly reduced following such regimens.Collectively, these data further enhance the overall benefits of reduced intensity regimens and the need for a stringent biological monitoring for assessment of the potential advantages of reduced intensity allo-BMT in comparison with conventional allo-BMT.

Abstract
Recipients of liver transplantation (LT) may develop immunological tolerance. Factors predictive of tolerance are not clearly understood. Transplant recipients with normal liver function tests and without active viral hepatitis or autoimmune disease who presented with side effects of immunosuppression or a high risk of de novo malignancies were selected to participate in this prospective study. Twenty-four patients fulfilled the inclusion criteria and, therefore, underwent a gradual reduction of immunosuppression. Tolerance was defined as normal liver function tests after immunosuppression withdrawal. Basal clinical and immunological characteristics, including lymphocyte counts and subpopulations (T, B, natural killer, CD4(+) , CD8(+) , and regulatory T cells) and the phytohemagglutinin stimulation index (SI), were compared for tolerant and nontolerant patients. Fifteen of the 24 patients (62.5%) were tolerant at a median of 14 months (interquartile range = 8.5-22.5 months) after complete immunosuppression withdrawal. Tolerant patients had a longer median interval between transplantation and inclusion in the study (156 for tolerant patients versus 71 months for nontolerant patients, P = 0.003) and a lower median SI (7.49 for tolerant patients versus 41.73 for nontolerant patients, P = 0.01). We identified 3 groups of patients with different probabilities of tolerance: in the first group (n = 7 for an interval > 10 years and an SI < 20), 100% reached tolerance; in the second group (n = 10 for an interval > 10 years and an SI > 20 or an interval < 10 years and an SI < 20), 60% reached tolerance; and in the third group (n = 7 for an interval < 10 years and an SI > 20), 29% reached tolerance. In conclusion, a high proportion of select LT recipients can reach tolerance over the long term. Two simple basal variables-the time from transplantation and the SI-may help to identify these patients.

Abstract
Common lymphoid progenitors (CLPs) are thought to represent major intermediates in the transition of hematopoietic stem cells (HSCs) to B lineage lymphocytes. However, it has been obvious for some time that CLPs are heterogeneous, and there has been controversy concerning their differentiation potential. We have now resolved four Flt3+ CLP subsets that are relatively homogenous and capable of forming B cells. Differentiation potential and gene expression patterns suggest Flt3+ CLPs lacking both Ly6D and RAG-1 are the least differentiated. In addition to B cells, they generate natural killer (NK) and dendritic cells (DCs). At the other extreme is a subset of the recently described Flt3+ Ly6D+ CLPs that have a history of RAG-1 expression and are B lineage restricted. These relatively abundant and potent CLPs were depleted within 48 hours of acute in vivo estrogen elevation, suggesting they descend from hormone regulated progenitors. This contrasts with the hormone insensitivity of other CLP subsets that include NK lineage progenitors. This progenitor heterogeneity and differentiation complexity may add flexibility in response to environmental changes. Expression of RAG-1 and display of Ly6D are both milestone events, but they are neither synchronized nor dependent on each other.

Abstract
OBJECTIVE To characterize baseline canine lymphocyte phenotypes including lymphocytes coexpressing multiple markers by novel 7-color multiparameter flow cytometry. STUDY DESIGN Fresh canine peripheral blood lymphocytes of 79 healthy 26-week-old Beagle or Beagle-mix dogs were stained and analyzed. RESULTS The high number of samples and acquired flow data (averaging 1.9 x 10(5) cells/sample) allowed the detection of minor lymphocyte subsets coexpressing multiple lymphocyte markers. The averaged percentages of major lymphocyte subsets of CD3+, CD4+, CD8+, CD21+ and gammadelta TCR+ cells from this study were 74.0, 43.6, 14.3, 9.6, and 0.2, respectively, which were comparable but uniquely different from other reports as they were simultaneously detected in the same sample. We demonstrated that the commonly used CD21 and CD3 monoclonal antibody (mAb) clones, previously recommended not to be used in the same staining, could and should be used together with the proper steps of lymphocyte gating. We found a high percentage (10.3%) of unidentified CD21- CD3+ CD4- CD8-gammadelta TCR- lymphocyte subset that has never been reported. The intensive gating strategy and the mean percentages of each lymphocyte subset to their parent subsets and to the total lymphocyte population are presented and discussed. CONCLUSION The canine lymphocyte phenotypes were fully characterized. This novel multiparameter flow cytometry method is a powerful approach to in-crease the accuracy of lymphocyte phenotyping in dogs.

Abstract
Myeloid leukemia factor 1-interacting protein (MLF1-IP) has been found to exert functions in mitosis, although studies have been conducted only in cell lines up to now. To understand its roles during ontogeny and immunity, we analyzed its mRNA expression pattern by in situ hybridization and generated MLF1-IP gene knockout (KO) mice. MLF1-IP was expressed at elevated levels in most rudimentary tissues during the mid-gestation stage, between embryonic day 9.5 (e9.5) and e15.5. It declined afterwards in these tissues, but was very high in the testes and ovaries in adulthood. At post-natal day 10 (p10), the retina and cerebellum still expressed moderate MLF1-IP levels, although these tissues do not contain fast-proliferating cells at this stage. MLF1-IP expression in lymphoid organs, such as the thymus, lymph nodes, spleen and bone marrow, was high between e15.5 and p10, and decreased in adulthood. MLF1-IP KO embryos failed to develop beyond e6.5. On the other hand, MLF1-IP+/− mice were alive and fertile, with no obvious anomalies. Lymphoid organ size, weight, cellularity and cell sub-populations in MLF1-IP+/− mice were in the normal range. The functions of MLF1-IP+/− T cells and naïve CD4 cells, in terms of TCR-stimulated proliferation and Th1, Th17 and Treg cell differentiation in vitro, were comparable to those of wild type T cells. Our study demonstrates that MLF1-IP performs unique functions during mouse embryonic development, particularly around e6.5, when there was degeneration of epiblasts. However, the cells could proliferate dozens of rounds without MLF1-IP. MLF1-IP expression at about 50% of its normal level is sufficient to sustain mice life and the development of their immune system without apparent abnormalities. Our results also raise an intriguing question that MLF1-IP might have additional functions unrelated to cell proliferation.

Abstract
Acute rejection, a common complication of lung transplantation, may promote obliterative bronchiolitis leading to graft failure in lung transplant recipients. During acute rejection episodes, CD8(+) T cells can contribute to lung epithelial injury but the mechanisms promoting and controlling CD8-mediated injury in the lung are not well understood. To study the mechanisms regulating CD8(+) T cell-mediated lung rejection, we used a transgenic model in which adoptively transferred ovalbumin (OVA)-specific cytotoxic T lymphocytes (CTL) induce lung injury in mice expressing an ovalbumin transgene in the small airway epithelium of the lungs (CC10-OVA mice). The lung pathology is similar to findings in humans with acute lung transplant. In the presence of an intact immune response the inflammation resolves by day 30. Using CC10-OVA.RAG(-/-) mice, we found that CD4(+) T cells and ICOS(+/+) T cells were required for protection against lethal lung injury, while neutrophil depletion was not protective. In addition, CD4(+)Foxp3 (+) ICOS(+) T cells were enriched in the lungs of animals surviving lung injury and ICOS(+/+) Tregs promoted survival in animals that received ICOS(-/-) T cells. Direct comparison of ICOS(-/-) Tregs to ICOS(+/+) Tregs found defects in vitro but no differences in the ability of ICOS(-/-) Tregs to protect from lethal lung injury. These data suggest that ICOS affects Treg development but is not necessarily required for Treg effector function.

Abstract
Innate Lymphoid cells (ILCs) are recently defined lymphocytes composed of several subsets such as Natural Killer (NK), Natural Helper (NH) and RORγt(+) cells, which have no antigen receptors but exhibit rapid cytokine production after stimulation. Murine RORγt(+) ILCs can be classified either as CCR6(+)c-kit(high)IL-7Rα(high) or CCR6NK(-)p46(+) cells. The former ones play roles on the formation of secondary lymphoid tissues and the later ones contribute to the maintenance of intestinal epithelial integrity by producing IL-22. Human fetal intestine, tonsil and lympho nodes harbor both NKp44 positive and negative RORγt(+) ILC subsets. Since human Crohn's disease patients have increased number of RORγt(+) ILCs in the inflamed intestine, roles of RORγt(+) ILCs on the pathogenesis of Crohn's disease became of great interest.

Abstract
A considerable variabilility in the effects of sample handling on NK cytotoxicity has been observed. Using flow cytometry, NK cytotoxicity assays and lymphocyte subset analysis of Ficoll-Hypaque-separated peripheral blood mononuclear cells (PBMCs) isolated from whole blood stored under various conditions were performed. The NK cytotoxicity of samples in heparin tubes stored overnight at 4 and 22°C, as well as at 22°C in acid citrate dextrose (ACD) tubes, was lower than that of a fresh sample. However, the NK cytotoxicity of samples in an ACD tube stored at 4°C was similar to that of a fresh sample. Based on lymphocyte subset analysis, samples in an ACD tube stored at 4°C showed a lower percentage of CD3+ T cells and a higher percentage of CD16/56+ NK cells compared to samples stored under other conditions. The NK cytotoxicity of fresh samples and samples in ACD tubes stored in a Styrofoam cooler box did not differ significantly; however, the differences were inconsistent. Overnight storage of peripheral blood in ACD tubes at 4°C is optimum for retention of NK cytotoxicity, the level of which is similar to that of fresh blood. This may be associated with an increased NK-cell fraction in Ficoll-Hypaque-separated PBMCs after overnight storage.

Abstract
Interleukin (IL)-22-producing innate lymphoid cells (ILCs; ILC22) comprise a heterogeneous population of cells that are dependent on the transcription factor retinoid-related orphan γt (RORγt) and are critical for barrier function of the intestinal mucosa. A distinct ILC22 subset expresses the natural cytotoxicity receptor NKp46 (NKp46+ ILC22); however, the factors that contribute to the generation of this population versus other subsets are largely unknown. Herein, we show that T-bet (encoded by Tbx21) was highly expressed in NKp46+ ILC22, a feature shared by all NKp46+ cells present in the intestine but not by other IL-22-producing populations. Accordingly, the absence of T-bet resulted in loss of NKp46+ ILC22 in the intestinal lamina propria. The residual NKp46+ ILC22 present in Tbx21(-/-) mice showed a marked reduction of Rorγt expression and impairment in IL-22 production. Generation and functions of gut NK1.1+ cells were also altered. Bone marrow chimera experiments revealed a cell-intrinsic requirement for T-bet in these subsets and competitive reconstitution experiments revealed roles for T-bet in multiple ILC subsets. Thus, T-bet has a general importance for ILC in the gut and plays a selective and critical role in the generation of NKp46+ ILC22.

Abstract
AIM Confirmation of immunostimulating effect of an original low molecular weight germanium organic compound (LMW-GOC) during immunization of mice with Vaxigrip vaccine. MATERIALS AND METHODS The experiments were carried out in CBA mice divided into 4 groups: control, those that received Vaxigrip influenza vaccine intraperitoneally, those that received LMW-GOC intraperitoneally and those that received both preparations at once. Effect of the preparations administered was evaluated by flow cytofluorometry based on changes of CD3, CD4, CD5, CD8, CD19, CD25, Foxp3, NK1.1, gammadelta T, MHC II, TLR2, TLR4, TLR9 expressing cell content in mice spleens. The content of the colored cells was determined at normal, 24 hours and 7 days after the administration of the preparations. Statistical treatment of the data was carried out by using Win MD 128 program package. RESULTS LMW-GOC can enhance the effect of Vaxigrip vaccine that is expressed by an increase of content in spleen of some lymphocyte subpopulations 24 hours and 7 days after the intraperitoneal administration. In some cases LMW-GOC increases the content of some lymphocyte subpopulations in mice spleen after administration as a monopreparation, i.e. without the vaccine. LMW-GOC suppressed stimulating effect of the vaccine on the spleen content of various lymphocyte subpopulations in none of the observations. CONCLUSION By using cytofluorometry method it is possible to form an understanding of an elevated role of various types of cells in the development of immune response to the vaccine as well as regarding additional enhancement of this response during administration of LMW-GOC to mice. The effect of the preparation is manifested for a few days after its administration. The preparation manifests adjuvant properties and after further studies may be suggested for use as an adjuvant.

Abstract
Absent T lymphocytes were unexpectedly found in homozygotes of a transgenic mouse from an unrelated project. T cell development did not progress beyond double-negative stage 1 thymocytes, resulting in a hypocellular, vestigial thymus. B cells were present, but NK cell number and B cell isotype switching were reduced. Transplantation of wild-type hematopoietic cells corrected the defect, which was traced to a deletion involving five contiguous genes at the transgene insertion site on chromosome 12C3. Complementation using bacterial artificial chromosome transgenesis implicated zinc finger BTB-POZ domain protein 1 (Zbtb1) in the immunodeficiency, confirming its role in T cell development and suggesting involvement in B and NK cell differentiation. Targeted disruption of Zbtb1 recapitulated the T(-)B(+)NK(-) SCID phenotype of the original transgenic animal. Knockouts for Zbtb1 had expanded populations of bone marrow hematopoietic stem cells and also multipotent and early lymphoid lineages, suggesting a differentiation bottleneck for common lymphoid progenitors. Expression of mRNA encoding Zbtb1, a predicted transcription repressor, was greatest in hematopoietic stem cells, thymocytes, and pre-B cells, highlighting its essential role in lymphoid development.

Abstract
OBJECTIVE To explore the changes of peripheral blood lymphocyte subsets in patients with acute hydrogen chloride gas poisoning. METHODS When the patients were admitted or on the secondary day, the percentages of total T-cell lymphocyte subsets (CD(3)(+)CD(19)(-)), CD(4)(+)T cells (CD(3)(+)CD(4)(+)), CD(8)(+)T cells (CD(3)(+)CD(8)(+)), B cells (CD(3)(-)CD(19)(+)) and NK cells (CD(3)(-)CD(16)(+)CD(56)(+)), and the ration of CD(4)(+)/CD(8)(+) in 37 cases with acute hydrogen chloride gas poisoning and 49 healthy controls were detected with flow cytometer. RESULTS The total T-cell percentage and total CD(4)(+)T cell percentage in 37 cases were significantly lower than those in 47 controls (P < 0.05). The percentages of NK cells and B lymphocytes in 37 cases significantly increased, as compared with controls (P < 0.05). The ration of CD(4)(+)/CD(8)(+) in 37 cases significantly decreased, as compared with controls (P < 0.05). CONCLUSION The lymphocyte subsets in the patients with acute hydrogen chloride gas poisoning changed, which could influence the immune function of patients.
