Abstract
Rheumatoid arthritis (RA) is one of the most common autoimmune joint disorders that leads to cartilage degradation. However, its specific correlation with immune cells has not been thoroughly clarified. Based on the two-sample Mendelian randomization (MR) analysis, the association between RA and 731 immune phenotypes which include morphological parameters (MP), relative cell (RC), median fluorescence intensities (MFI), and absolute cells (AC) was comprehensively determined. After false discovery rate correction, RA and immunophenotypes were statistically associated with each other. It was observed that four immune phenotypes, including 1 MPs, 8 RCs, 15 MFIs, and 10 ACs were causally associated with the risk of RA. Meanwhile, several identified immune traits could serve as independent factors for RA and be robust against pleiotropy. While considering the role of RA in immune traits, the involvement of RA in multiple immunophenotypes including CD62L- myeloid DC AC, CD3 on secreting Treg, CD3 on activated and secreting Treg, and CD3 on CD4 Treg was revealed. This study is the first comprehensive evaluation of the interaction between immune response and RA risk, thus providing therapeutic strategies for RA from an immunological perspective.

Abstract
Lifestyle, diet, socioeconomic status and genetics all contribute to heterogeneity in immune responses. Vietnam is plagued with a variety of health problems, but there are no available data on immune system values in the Vietnamese population. This study aimed to establish reference intervals for immune cell parameters specific to the healthy Vietnamese population by utilizing multi-color flow cytometry (MCFC). We provide a comprehensive analysis of total leukocyte count, quantitative and qualitative shifts within lymphocyte subsets, serum and cytokine and chemokine levels and functional attributes of key immune cells including B cells, T cells, natural killer (NK) cells and their respective subpopulations. By establishing these reference values for the Vietnamese population, these data contribute significantly to our understanding of the human immune system variations across diverse populations. These data will be of substantial comparative value and be instrumental in developing personalized medical approaches and optimizing diagnostic strategies for individuals based on their unique immune profiles.

Lymphocyte subset phenotyping for the prediction of progression to inflammatory arthritis in anti-citrullinated-peptide antibody-positive at-risk individuals. Rheumatology (Oxford) 2024; 63:1720-1732. [PMID: 37676828 PMCID: PMC11147546 DOI: 10.1093/rheumatology/kead466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 08/15/2023] [Accepted: 08/18/2023] [Indexed: 09/09/2023] Open
Abstract
OBJECTIVES Inflammatory arthritis (IA) is considered the last stage of a disease continuum, where features of systemic autoimmunity can appear years before clinical synovitis. Time to progression to IA varies considerably between at-risk individuals, therefore the identification of biomarkers predictive of progression is of major importance. We previously reported on the value of three CD4+T cell subsets as biomarkers of progression. Here, we aim to establish the value of 18 lymphocyte subsets (LS) for predicting progression to IA. METHODS Participants were recruited based on a new musculoskeletal complaint and being positive for anti-citrullinated-peptide antibody. Progression (over 10 years) was defined as the development of clinical synovitis. LS analysis was performed for lymphocyte lineages, naive/memory subsets, inflammation-related cells (IRC) and regulatory cells (Treg/B-reg). Modelling used logistic/Cox regressions. RESULTS Of 210 patients included, 93 (44%) progressed to IA, 41/93 (44%) within 12 months (rapid progressors). A total of 5/18 LS were associated with progression [Treg/CD4-naïve/IRC (adjusted P < 0.0001), CD8 (P = 0.021), B-reg (P = 0.015)] and three trends (NK-cells/memory-B-cells/plasmablasts). Unsupervised hierarchical clustering using these eight subsets segregated three clusters of patients, one cluster being enriched [63/109(58%)] and one poor [10/45(22%)] in progressors. Combining all clinical and LS variables, forward logistic regression predicted progression with accuracy = 85.7% and AUC = 0.911, selecting smoking/rheumatoid-factor/HLA-shared-epitope/tender-joint-count-78 and Treg/CD4-naive/CD8/NK-cells/B-reg/plasmablasts. To predict rapid progression, a Cox regression was performed resulting in a model combining smoking/rheumatoid factor and IRC/CD4-naive/Treg/NK-cells/CD8+T cells (AUC = 0.794). CONCLUSION Overall, progression was predicted by specific LS, suggesting potential triggers for events leading to the development of IA, while rapid progression was associated with a different set of subsets.

Gene association analysis to determine the causal relationship between immune cells and juvenile idiopathic arthritis. Pediatr Rheumatol Online J 2024; 22:35. [PMID: 38459548 PMCID: PMC10921670 DOI: 10.1186/s12969-024-00970-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 02/21/2024] [Indexed: 03/10/2024] Open
Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a type of chronic childhood arthritis with complex pathogenesis. Immunological studies have shown that JIA is an acquired self-inflammatory disease, involving a variety of immune cells, and it is also affected by genetic and environmental susceptibility. However, the precise causative relationship between the phenotype of immune cells and JIA remains unclear to date. The objective of our study is to approach this inquiry from a genetic perspective, employing a method of genetic association analysis to ascertain the causal relationship between immune phenotypes and the onset of JIA. METHODS In this study, a two-sample Mendelian randomization (MR) analysis was used to select single nucleotide polymorphisms (SNPs) significantly associated with immune cells as instrumental variables to analyze the bidirectional causal relationship between 731 immune cells and JIA. There were four types of immune features (median fluorescence intensity (MFI), relative cellular (RC), absolute cellular (AC), and morphological parameters (MP)). Finally, the heterogeneity and horizontal reproducibility of the results were verified by sensitivity analysis, which ensured more robust results. RESULTS We found that CD3 on CM CD8br was causally associated with JIA at the level of 0.05 significant difference (95% CI = 0.630 ~ 0.847, P = 3.33 × 10-5, PFDR = 0.024). At the significance level of 0.20, two immunophenotypes were causally associated with JIA, namely: HLA DR on CD14+ CD16- monocyte (95% CI = 0.633 ~ 0.884, P = 6.83 × 10-4, PFDR = 0.16) and HLA DR on CD14+ monocyte (95% CI = 0.627 ~ 0.882, P = 6.9 × 10-4, PFDR = 0.16). CONCLUSION Our study assessed the causal effect of immune cells on JIA from a genetic perspective. These findings emphasize the complex and important role of immune cells in the pathogenesis of JIA and lay a foundation for further study of the pathogenesis of JIA.

Abstract
Rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPAs) are the most frequently used rheumatoid arthritis (RA) diagnostic markers, but they are unable to anticipate the patient's evolution or response to treatment. The aim of this study was to identify possible severity biomarkers to predict an upcoming flare-up or remission period. To address this objective, sera and anticoagulated blood samples were collected from healthy controls (HCs; n = 39) and from early RA (n = 10), flare-up (n = 5), and remission (n = 16) patients. We analyzed leukocyte phenotype markers, regulatory T cells, cell proliferation, and cytokine profiles. Flare-up patients showed increased percentages of cluster of differentiation (CD)3+CD4- lymphocytes (p < 0.01) and granulocytes (p < 0.05) but a decreased natural killer (NK)/T lymphocyte ratio (p < 0.05). Analysis of leukocyte markers by principal component analysis (PCA) and receiver operating characteristic (ROC) curves showed that CD45RO+ (p < 0.0001) and CD45RA+ (p < 0.0001) B lymphocyte expression can discriminate between HCs and early RA patients, while CD3+CD4- lymphocyte percentage (p < 0.0424) and CD45RA+ (p < 0.0424), CD62L+ (p < 0.0284), and CD11a+ (p < 0.0185) B lymphocyte expression can differentiate between flare-up and RA remission subjects. Thus, the combined study of these leukocyte surface markers could have potential as disease severity biomarkers for RA, whose fluctuations could be related to the development of the characteristic pro-inflammatory environment.

Int Immunopharmacol 2023; 114:109399. [PMID: 36442285 DOI: 10.1016/j.intimp.2022.109399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 10/12/2022] [Accepted: 10/26/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND CD8+ T cells are plentiful in rheumatoid arthritis (RA) and have a important role in it's pathogenesis. Many subsets have been identified in CD8+ T cells, however, the relationship between CD8+ T subpopulations and disease activity of RA is poorly defined. Here we detected different CD8+ T cell subsets in peripheral blood and examined their relationships with clinical features and serological parameters in RA. METHODS CD8+ T cell phenotypes and percentages in peripheral blood were determined by flow cytometry in 39 patients with RA. The clinical characteristics and serological parameters of RA patients were collected and DAS28-ESR was measured as indicator of disease activity. Linear regression was performed to assess the correlation of CD8+ T cell subsets with RA clinical variables. RESULTS Naive CD8+ T cells were significantly and negatively correlated with RA disease activity indicator DAS28-ESR(r2 = 0.1027, p = 0.0468), erythrocyte sedimentation rate (ESR)(r2 = 0.1891, p = 0.0057), clinical disease activity index(CDAI)(r2 = 0.1474, p = 0.0158), simplified disease activity index(SDAI)(r2 = 0.1465, p = 0.0255), and duration(r2 = 0.1247, p = 0.0274). And the percent of naive CD8+ T cells were obviously decreased in RA with high disease activity when compared with RA in low disease activity(p < 0.01). In addition, Our results indicated significant positive correlations between CD8+ CD28- T cells and DAS28-ESR(r2 = 0.1881, p = 0.0058), ESR(r2 = 0.2279, p = 0.0021), c reaction protein (CRP)(r2 = 0.2203, p = 0.0051), CDAI (r2 = 0.1778, p = 0.0075), SDAI (r2 = 0.2618, p = 0.0020), rheumatoid factor(RF)(r2 = 0.1823, p = 0.0067), age(r2 = 0.1968, p = 0.0047), as well as similar positive correlations between CD8+ CD27- T cells and DAS28-ESR(r2 = 0.1661, p = 0.01), ESR(r2 = 0.1586, p = 0.012), CRP(r2 = 0.1778, p = 0.013), CDAI (r2 = 0.1622, p = 0.0110), SDAI(r2 = 0.2316, p = 0.0040), RF(r2 = 0.2097, p = 0.0034), age(r2 = 0.1932, p = 0.0051). Furthermore, interesting results showed observable positive correlations between activated CD8+ T cells and total cholesterol(TC)(r2 = 0.2757, p = 0.0007), triglyceride(TG)(r2 = 0.2886, p = 0.0005), low density lipoprotein(LDL-C)(r2 = 0.09643, p = 0.0264) and Krebs yon denlungen-6(KL-6)(r2 = 0.4171, p = 0.0002). And TCRγδ + CD8+ T cells were also found positively related with total cholesterol(TC)(r2 = 0.5015, p < 0.0001), triglyceride(TG)(r2 = 0.2031, p = 0.0045), and KL-6(r2 = 0.2122, p = 0.0136). CONCLUSIONS Our results suggest that naive CD8+ T cells, CD8+ CD28- T cells, and CD8+ CD27- T cells are obviously correlated with inflammation and disease activity of RA. While activated CD8+ T cells and TCRγδ + CD8+ T cells may involve in lipidmetabolism and lung fibrosis of RA. These CD8+ T cell subsets may be new biomarkers and targets for RA disease evaluation, therapeutic target-selecting, curative effects and prognoses assessment.

Different Types of Chronic Inflammation Engender Distinctive Immunosenescent Profiles in Affected Patients. Int J Mol Sci 2022; 23:ijms232314688. [PMID: 36499016 PMCID: PMC9735546 DOI: 10.3390/ijms232314688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022] Open
Abstract
Immunosenescence encompasses a spectrum of lymphocyte phenotypic alterations. The aim of the study was to evaluate immunosenescent effect of two different forms of chronic inflammation, Systemic Lupus Erythematosous (SLE), a systemic autoimmune disease, and End-Stage Kidney Disease (ESKD), a chronic inflammatory disorder. Certain lymphocyte surface molecules, including CD31, CD45RA, CCR7, CD28, CD57, for T, and IgD, CD27 for B lymphocytes, were analyzed by flow cytometry in 30 SLE and 53 ESKD patients on hemodialysis (HD), and results were compared to 31 healthy controls (HC) of similar age, gender, and nationality. Significant Lymphopenia was evident in both SLE and ESKD-HD patients, compared to HC, affecting B cells 75.4 (14.4−520.8), 97 (32−341), and 214 (84−576) cells/μL, respectively, p < 0.0001, and CD4 cells 651.2 (71.1−1478.2), 713 (234−1509), and 986 (344−1591) cells/μL, respectively, p < 0.0001. The allocation of B cell subpopulations was remarkably different between SLE and ESKD-HD patients. SLE showed a clear shift to senescence (CD19IgD-CD27−) cells, compared to ESKD-HD and HC, 11.75 (10)% vs. 8 (6) vs. 8.1 (10), respectively. Regarding T lymphocytes, Central Memory CD8 cells predominated in both SLE and ESKD-HD patients compared to HC, 53 (50)%, 52 (63), and 24 (64)%, respectively, while ESKD-HD but not SLE patients also had increased expression of CD4CD28− and CD8CD28− cells. In conclusion, both diseases are followed by significant lymphopenia; however, the senescent phenomenon affects the B lymphocyte compartment in SLE patients and T lymphocytes in ESKD-HD patients.

FLOT and CROSS chemotherapy regimens alter the frequency of CD27+ and CD69+ T cells in oesophagogastric adenocarcinomas: implications for combination with immunotherapy. J Cancer Res Clin Oncol 2022:10.1007/s00432-022-04283-9.

Abstract
AbstractCombining immunostimulatory chemotherapies with immunotherapy is an attractive strategy to enhance treatment responses in oesophagogastric junctional adenocarcinoma (OGJ). This study investigates the immunostimulatory properties of FLOT, CROSS and MAGIC chemotherapy regimens in the context of OGJ using in vitro and ex vivo models of the treatment-naïve and post-chemotherapy treated tumour microenvironment. FLOT and CROSS chemotherapy regimens increased surrogate markers of immunogenic cell death (HMGB1 and HLA-DR), whereas the MAGIC treatment regimen decreased HMGB1 and HLA-DR on OGJ cells (markedly for epirubicin). Tumour-infiltrating and circulating T cells had significantly lower CD27 expression and significantly higher CD69 expression post-FLOT and post-CROSS treatment. Similarly, the supernatant from FLOT- and CROSS-treated OGJ cell lines and from FLOT- and CROSS-treated OGJ biopsies cultured ex vivo also decreased CD27 and increased CD69 expression on T cells. Following 48 h treatment with post-FLOT and post-CROSS tumour conditioned media the frequency of CD69+ T cells in culture negatively correlated with the levels of soluble immunosuppressive pro-angiogenic factors in the conditioned media from ex vivo explants. Supernatant from FLOT- and CROSS-treated OGJ cell lines also increased the cytotoxic potential of healthy donor T cells ex vivo and enhanced OGJ patient-derived lymphocyte mediated-killing of OE33 cells ex vivo. Collectively, this data demonstrate that FLOT and CROSS chemotherapy regimens possess immunostimulatory properties, identifying these chemotherapy regimens as rational synergistic partners to test in combination with immunotherapy and determine if this combinatorial approach could boost anti-tumour immunity in OGJ patients and improve clinical outcomes.

Abstract
Despite introduction of biological disease modifying anti-rheumatic drugs (DMARDs) for Rheumatoid arthritis (RA) treatment, therapeutic strategies do not always lead to disease control and remission. Hence, a more efficient patient stratification and monitoring biomarkers and tools are needed to enable a more personalized medicine. We used a whole blood based functional flow cytometry assay to characterize immune cells from RA patients (treated or not), healthy donors and psoriatic arthritis (PsA) patients according to their responses to LPS and/or anti-TNFα (infliximab, IFX). Activation marker expression was measured using a 10-color flow cytometry panel following a no-wash protocol. Naïve-to-treatment RA patients had a stronger inflammatory profile in comparison to healthy donors at basal level. Higher expression of activation markers (CD69 and/or CD11b) on NK, B cells and granulocytes and lower expression of the adhesion molecule CD62L were measured on monocytes, granulocytes and B cells. After LPS, naïve RA patients' cells were less capable of regulating CD69, CD11b, CD16 or CD62L showing impaired activation capabilities. Upon LPS and IFX co-incubation, hierarchical clustering analysis showed different profiles between cohorts. We believe that this whole blood-based approach should further be assessed for RA patient characterization as it provides new perspectives for stratification and/or monitoring.

Canine memory T-cell subsets in health and disease. Vet Immunol Immunopathol 2022; 246:110401.

Abstract
A more complete understanding of canine T-lymphocyte immunity is necessary for improving diagnostic and therapeutic approaches to canine diseases, developing cell-based canine immunotherapeutics, and evaluating dogs as large mammal models for comparative immunology research. The aim of this study was to utilize CD45RA (indicating antigen inexperience) and CD62L (indicating lymph node homing capability), to quantify canine memory T-cell subsets in healthy dogs and dogs with various diseases. Peripheral blood mononuclear cells (PBMCs) were prospectively collected from dogs belonging to one of four groups:dermatologic inflammation (n = 9), solid tumors (n = 9), lymphoma (n = 9), and age-/weight-matched healthy control dogs (n = 15). Dogs receiving prednisone or any other immunomodulating medication within two weeks were excluded. Flow cytometry was performed and T-cell subsets were defined as CD4+ or CD8+, and naïve (TN), central memory (CM), effector memory (EM), or terminal effector memory re-expressing CD45RA (TEMRA). T-cell subset proportions were compared between each disease group and their healthy age-/weight-matched controls using a Mann-Whitney test. Significantly increased %CD8+ TN (P = 0.036) and decreased %CD8+ TEMRA (P = 0.045) were detected in dogs with dermatologic inflammation compared to healthy controls. Furthermore, %CD4+ TN positively correlated with Canine Atopic Dermatitis Extent and Severity Index (CADESI) score within the inflammation group (ρ = 0.817, P = 0.011). No significant differences between either cancer group and their healthy controls were detected. Taken together, these data indicate that dermatologic inflammation can alter proportions of peripheral blood T-cell subsets, possibly due to the migration of antigen-specific T-cells into tissues. Furthermore, these findings support the utility of CD45RA and CD62L in characterizing clinical canine immune responses.

Abstract
Cumulative evidence suggests that abnormal differentiation of T lymphocytes influences the pathogenesis of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Thus, understanding the immune activation landscape of CP/CPPS would be helpful for improving therapeutic strategies. Here, we utilized BD™ AbSeq to digitally quantify both the protein and mRNA expression levels in single peripheral blood T cells from two CP/CPPS patients and two healthy controls. We utilized an integrated strategy based on canonical correlation analysis of 10 000+ AbSeq profiles and identified fifteen unique T‐cell subpopulations. Notably, we found that the proportion of cluster 0 in the CP/CPPS group (30.35%) was significantly increased compared with the proportion in the healthy control group (9.38%); cluster 0 was defined as effector T cells based on differentially expressed genes/proteins. Flow cytometry assays confirmed that the proportions of effector T‐cell subpopulations, particularly central memory T cells, T helper (Th)1, Th17 and Th22 cells, in the peripheral blood mononuclear cell populations of patients with CP/CPPS were significantly increased compared with those of healthy controls (P < 0.05), further confirming that aberration of effector T cells possibly leads to or intensifies CP/CPPS. Our results provide novel insights into the underlying mechanisms of CP/CPPS, which will be beneficial for its treatment.

Abstract
It has been reported Human Leukocyte Antigen (HLA) gene polymorphism is a risk factor for the development of Behçet’s disease (BD). In this study, the association of HLA class II subtypes HLA-DP, DQ, DR, and T cell subsets in BD patients with arthritis was evaluated. Frequencies of HLA-DP, DQ, DR positive cells, and T cell subsets in peripheral blood leukocytes (PBL) were measured by flow cytometric analysis in BD, and compared to rheumatoid arthritis as disease controls and healthy controls. Frequencies of HLA-DQ were significantly decreased in whole PBL and granulocytes of BD active patients as compared to healthy controls. In monocytes populations, proportions of HLA-DR positive cells were significantly increased in BD active patients as compared to healthy controls. Proportions of CD4+CCR7+ and CD8+CCR7+ cells were significantly higher in BD active patients than in BD inactive in whole PBL. Frequencies of CD4+CD62L- and CD8+CD62L- cells in lymphocytes were significantly decreased in active BD than those in inactive BD. There were also correlations between disease activity markers and T cell subsets. Our results revealed HLA-DP, DQ, and DR expressing cell frequencies and several T cell subsets were significantly correlated with BD arthritis symptoms.

Abstract
TNFα inhibitors have shaped the landscape of rheumatoid arthritis (RA) therapy with high clinical efficiency. However, their impact on T cell recall responses is not well-elucidated. We aimed to analyze the immune profiles of memory T cells in RA patients undergoing TNFα inhibitor Golimumab (GM) treatment. Frequencies of peripheral T cell subsets and cytokine expression profiles in memory T cells (TM) upon PMA/Ionomycine stimulation were determined by flow cytometry. Antigen-specific CD8 T cell immunity was analyzed through stimulating PBMCs with CMV-EBV-Flu (CEF) viral peptide pool and subsequent intracellular IFNγ staining. Both peripheral CD8 and CD4 T cells from GM treated patients had a shift pattern characterized by an enlarged effector TM and a reduced central TM cell population when compared to GM untreated group. An increase in the frequencies of TNFα+, IL-2+, and IL-17+ CD8 TM cells was observed whereas only TNFα+CD4 TM cells increased in GM treated patients. Moreover, GM treated patients contained more peripheral IFNγ-producing CD8 T cells specific to CEF viral peptides. Together, these results show a distinct T cell subset pattern and enhanced memory T cell immunity upon GM treatment, suggesting an immunoregulatory effect of TNF inhibitor Golimumab on peripheral memory T cell responses.

Abstract
UV radiation (UVR) causing DNA damage is a well-documented risk factor for nonmelanoma skin cancer. Although poorly understood, UVR may also indirectly contribute to carcinogenesis by promoting immune evasion. To our knowledge, we report the first epidemiological study designed to investigate the association between quantitative measures of UVR, obtained using a spectrophotometer, and circulating T regulatory (Treg) cells. In addition to total Treg cells, the proportion of functionally distinct Treg cell subsets defined by CD45RA and CD27 phenotypic markers, graded expression of FOXP3 and CD25, and those expressing cutaneous lymphocyte-associated Ag and the chemokine receptor CCR4 were enumerated in 350 individuals undergoing routine skin cancer screening exams and determined not to have prevalent skin cancer. No associations were identified for UVR exposure or the overall proportion of circulating Treg cells; however, Treg cell subpopulations with an activation-associated phenotype, CD45RA-/CD27-, and those expressing cutaneous homing receptors were significantly positively associated with UVR. These subpopulations of Treg cells also differed by age, sex, and race. After stratification by natural skin tone, and adjusting for age and sex, we found that spectrophotometer-based measures of UVR exposure, but not self-reported measures of past sun exposure, were positively correlated with the highest levels of these Treg cell subpopulations, particularly among lighter-skinned individuals. Findings from this large epidemiologic study highlight the diversity of human Treg cell subpopulations associated with UVR, thus raising questions about the specific coordinated expression of CD45RA, CD27, CCR4, and cutaneous lymphocyte-associated Ag on Treg cells and the possibility that UVR contributes to nonmelanoma skin cancer carcinogenesis through Treg cell-mediated immune evasion.

Abstract
Endometrial mesenchymal stem cells (endMSCs) reside in the basal and functional layer of human endometrium and participate in tissue remodelling, which is required for maintaining the regenerative capacity of the endometrium. The endMSCs are multipotent stem cells and exhibit immunomodulatory effects. This paper aimed to evaluate the regulatory effects of extracellular vesicles derived from endMSCs (EV-endMSCs) in the setting of T cell activation. In vitro stimulations of lymphocytes were performed in the presence of EV-endMSCs. These in vitro-stimulated lymphocytes were functionally and phenotypically characterized to distinguish CD4+ and CD8+ T cell differentiation subsets. Moreover, the inhibition of TGFβ was performed with neutralizing antibodies. The phenotype and nanoparticle tracking analysis of the EV-endMSCs demonstrated that they are similar in terms of size distribution to other mesenchymal stem cells-derived exosomes. The in vitro assays showed an immunomodulatory potential of these vesicles to counteract the differentiation of CD4+ T cells. The quantification of active TGFβ in EV-endMSCs was found to be very high when compared with extracellular vesicles-free concentrated supernatants. Finally, the neutralization of TGFβ significantly attenuated the immunomodulatory activity of EV-endMSCs. In summary, this is the first report demonstrating that EV-endMSCs exhibit a potent inhibitory effect against CD4+ T cell activation, which is partially mediated by TGFβ signalling.

Abstract
Among patients with venous thromboembolism (VTE), the persistent detection of antiphospholipid (aPL) antibodies (Ab) represents an independent high risk factor for recurrence. However, oral anticoagulation vitamin K antagonist therapy, frequently used in these patients, is problematic in assessing and/or confirming a diagnosis of primary aPL syndrome (pAPS), suggesting use of alternative strategies. For this reason, and by analogy with other autoimmune diseases, a flow cytometer approach testing peripheral T cell subsets (CD3, CD4, and CD8), B cell subsets (B1, transitional, naive, and memory), and NK cells can be proposed. As an example and to validate the concept, pAPS patients selected from the monocentric VTE case-control EDITH's cohort were selected during their follow-up. As suspected and in contrast to non-APS VTE patients, other autoimmune diseases, and controls, pAPS VTE patients displayed specific lymphocyte disturbances. Quantitative and qualitative modifications were related to total CD4+ T cell reduction, a lower CD4/CD8 ratio, and disturbance in B cell homeostasis with increased proportions of B1 cells, transitional B cells (CD24++CD38++), and naive B cells (IgD+CD27-), while memory B cells (IgD+CD27+ and IgD-CD27+) were reduced. Interestingly, the absolute number of CD4+ T cells positively correlated with IgG anti-cardiolipin Ab levels. Altogether, disturbances of T and B cell homeostasis characterized pAPS VTE patients during their follow-up. This suggests a means of profiling that could be used in addition to existing criteria to characterize them.

Abstract
Rheumatoid arthritis is one major chronic inflammatory systemic autoimmune disease. The CD154-CD40 interactions play a critical role in the regulation of immune responses and the maintenance of autoimmunity. Therefore, we aimed to determine whether anti-CD154 antibody treatment show positive effects on immunomodulation and clinical improvement of sustained severe rheumatoid arthritis in cynomolgus monkeys. Arthritis was induced using chicken type II collagen (CII) and arthritic monkey were divided into control and anti-CD154 treatment groups based on their concentrations of anti-CII antibodies on week 7 post-immunization. Blood and tissue samples were collected on week 16 post-immunization. Anti-CD154 antibody treatment improved arthritis and movement, and significantly decreased the numbers of proliferating B cells and the serum levels of anti-type II collagen antibody and sCD154 compared with non-treatment group. Further anti-CD154 antibody treatment significantly decreased the percentage of CD4+ cells and the ratio of CD4+ to CD8+ T cells and significantly increased the percentage of CD8+ cells and effector memory CD8+ cells in peripheral blood. We have shown for the first time in a nonhuman primate model of RA that CD154 blockade has beneficial effects. This study might be valuable as preclinical data of CD154 blockade in nonhuman primate models of severe rheumatoid arthritis.

Abstract
Aberrant T cell phenotype is one of the characteristics of myelodysplastic syndromes (MDS). In this study, we detected an increased concentration of IL-15 in the plasma of MDS patients (n = 20) compared with that in the plasma of healthy controls (n = 20). In MDS patients, reduced naïve CD4+ and CD8+ T cells [16.11 ± 6.56 vs. 24.11 ± 7.18 for CD4+ T cells (p < 0.001) and 13.15 ± 5.67 vs. 23.51 ± 6.25 for CD8+ T cells (p < 0.001)] were observed. The reduced naïve and increased effector memory T cells were significantly correlated with IL-15 plasma level. Then, the effect of IL-15 and IL-7 was tested in vitro. Peripheral blood mononuclear cells from MDS were treated for 15 days with IL-15. This treatment significantly decreased naïve CD4+ (p < 0.001) and CD8+ (p < 0.001) T cells and correspondingly increased terminal memory CD4+ and CD8+ T cells (p < 0.001). Treatment with IL-7 increased naïve CD4+ (p < 0.05) and CD8+ (p < 0.001) T cells. Our results indicated that exposure to high levels of IL-15 may be involved in the T cell phenotype conversion observed in MDS. IL-7 may be one of the promising therapeutic candidates for recovering the effector immune compartment in MDS patients.

Abstract
We report the case of a patient with acute necrotizing colitis due to invasive amebiasis associated with CD4 lymphopenia and impaired neutrophil responses. The course of the disease was characterized by CMV reactivation and severe and recurrent bacterial and fungal infections, which might be related to the decreased CD4 T cell count and the impaired functional capacities of neutrophils, respectively. The clinical outcome was positive with normalization of both CD4 cell count and neutrophil functions.

Abstract
Immune gender differences have been reported, but are little studied in elderly humans. We compared monocyte and lymphocyte subsets, along with soluble immune mediators in healthy men and women over the age of 70. We also measured natural killer (NK) lymphocyte cytotoxic granule exocytosis, chemokine synthesis, and cytokine synthesis in response to a variety of stimuli. Elderly women had significantly more circulating B cells than men, whereas men had more CD4 central memory T cells and higher monocyte levels. Plasma adiponectin levels were higher in women, plasma retinol-binding protein 4 levels were higher in men, but there were no significant gender differences in C-reactive protein, IL-15, or sphingosine-1-phosphate. Women had a higher ratio of immature CD56(bright) NK cells to mature CD56(dim) NK cells, indicating a gender difference in NK cell maturation in the elderly. Comparing sexes, female mature NK cells had more vigorous cytotoxic granule responses to K562 leukemia cells and IFN-γ responses to NKp46 crosslinking. Moreover, female NK cells were more likely to produce MIP-1β in response to a variety of stimuli. These data show that gender influences NK cell activity in elderly humans.

Abstract
Although many studies are focused on auto-reactive CD4(+) T cells, the precise role of CD8(+) T cells in autoimmunity is poorly understood. The objective of this study is to provide more insight into the phenotype and function CD8(+) T cells during the development of autoimmune disease by studying CD8(+) T cells in human lymph-node biopsies and peripheral blood obtained during the earliest phases of rheumatoid arthritis (RA). Here, we show that lymphoid pro-inflammatory CD8(+) T cells exhibit a less-responsive phenotype already during the earliest phases of autoimmunity compared with healthy individuals. We found an increase in CD8(+) memory T cells in lymphoid tissue during the earliest phases of autoimmunity, even before clinical onset of RA, accompanied by an increased frequency of non-circulating or recently activated (CD69(+)) CD8(+) T cells in lymphoid tissue and peripheral blood. Importantly, lymphoid pro-inflammatory CD8(+)IL-17A(+) T cells displayed a decreased capacity of cytokine production, which was related to disease activity in early RA patients. In addition, a decreased frequency of regulatory CD8(+)IL-10(+) T cells in peripheral blood was also related to disease activity in early RA patients. Our results suggest that different CD8(+) T-cell subsets are affected already during the earliest phases of systemic autoimmunity.

Abstract
CD45 is a transmembrane protein tyrosine phosphatase that is specifically expressed in hematopoietic cells and can initiate signal transduction via the dephosphorylation of tyrosine. Alternatively spliced transcript variants of this gene encode distinct isoforms, which indicate different functional states of CD45. Among these variants, CD45RO, which contains neither exon 4, 5, or 6, is over-expressed in lymphocytes in autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, and type I diabetes. The CD45 RO serves as a marker of the immune response activity and lymphocyte development. Previous studies have indicated that exon splicing is generally correlated with local hypermethylated DNA and acetylated histone modification, while autoimmune diseases are commonly associated with global hypomethylation and histone deacetylation in lymphocytes. Thus, the question arises of how exons 4, 5, and 6 of CD45RO are excluded under the status of global DNA hypomethylation and histone deacetylation in these autoimmune diseases. On the basis of the analyses of the context sequence of CD45 and its natural antisense RNA in GenBank, we proposed that the long noncoding RNA encoded by the natural antisense gene of CD45 contributes to the expressional regulation of the CD45RO splicing variant via recruitment of DNA methyltransferase and histone modification modulators specific to the sense gene CD45; thus, it is associated with the over-expression of CD45RO and the functional regulation of lymphocytes in the pathogenic development of autoimmune diseases.

Abstract
Endothelial cells closely interact with circulating lymphocytes. Aggression or activation of the endothelium leads to an increased shedding of endothelial cell microparticles (MP). Endothelial MP (EMP) are found in high plasma levels in numerous immunoinflammatory diseases, such as atherosclerosis, sepsis, multiple sclerosis, and cerebral malaria, supporting their role as effectors and markers of vascular dysfunction. Given our recently described role for human brain microvascular endothelial cells (HBEC) in modulating immune responses, we investigated how HBEC-derived MP could interact with and support the proliferation of T cells. Like their mother cells, EMP expressed molecules important for Ag presentation and T cell costimulation, that is, β2-microglobulin, MHC II, CD40, and ICOSL. HBEC were able to take up fluorescently labeled Ags with EMP also containing fluorescent Ags, suggestive of Ag carryover from HBEC to EMP. In cocultures, fluorescently labeled EMP from resting or cytokine-stimulated HBEC formed conjugates with both CD4(+) and CD8(+) subsets, with higher proportions of T cells binding EMP from cytokine-stimulated cells. The increased binding of EMP from cytokinestimulated HBEC to T cells was VCAM-1 and ICAM-1 dependent. Finally, in CFSE T cell proliferation assays using anti-CD3 mAb or T cell mitogens, EMP promoted the proliferation of CD4(+) T cells and that of CD8(+) T cells in the absence of exogenous stimuli and in the T cell mitogenic stimulation. Our findings provide novel evidence that EMP can enhance T cell activation and potentially ensuing Ag presentation, thereby pointing toward a novel role for MP in neuroimmunological complications of infectious diseases.

Abstract
Whether the efficacy of lenalidomide in the treatment of multiple myeloma (MM) is due to direct tumor toxicity only or to additional immunomodulatory effects is unclear. We studied the effect of lenalidomide treatment on T-cell immune reconstitution in patients with MM who had undergone autologous peripheral blood stem cell transplant (ASCT). Twenty-nine newly diagnosed patients with MM received induction therapy followed by high-dose melphalan and ASCT. After ASCT, 11 patients received lenalidomide consolidation therapy for 2 months followed by maintenance therapy until disease progression. The remaining 18 patients received no treatment. Serial analysis of thymic output, as given by numbers of T-cell receptor excision circles (sjTRECs), and T-cell phenotyping was performed until 18 months post-ASCT. Lenalidomide impaired long-term thymic T-cell reconstitution, decreased CD4 + and CD8 + CD45RA + CCR7 - effector-terminal T-cell absolute counts and increased CD4 + CD25 + CD127 - /low regulatory T-cells. Lenalidomide consolidation and long-term maintenance therapy, administered post-ASCT, may have a potentially negative impact on immune surveillance.

Abstract
The objective of this study was to compare between the effects of mesenchymal stem cell (MSC) and betamethasone in the treatment of rheumatoid arthritis. Sixty male albino mice were divided equally into 2 models. They are MSC model, group 1: saline control group, group 2: collagen-induced arthritis (CIA), group 3: induced arthritis mice that received intravenous injection of MSCs. Betamethasone model, group 1: phosphate buffer saline, group 2: CIA, group 3: induced arthritis mice that received intraperitoneal injection of betamethasone. Mice arthritis models were assessed by clinical paw edema and X-rays, at the proper time of sacrefaction, tissues were collected and examined using real-time PCR, and synovial tissue was examined for interleukin-10, tumor necrosis factor α, cartilage oligomeric matrix protein and matrix metalloproteinase 3. While serum levels of rheumatoid factor and C-reactive protein were detected by enzyme-linked immunosorbent assay kits. Also blood erythrocyte sedimentation rate was detected. Histopathological, paw edema and PCR results showed improvement in the groups that received MSC compared with the diseased group and the groups which received betamethasone. MSC significantly enhanced the effect of collagen-induced arthritis treatment, which is superior to betamethasone treatment, likely through the modulation of the expression of various cytokines.

Abstract
Human CD4+ T cells can be classified as either naïve, central memory (TCM), or effector memory (TEM) cells. To identify the CD4+ T cell subsets most important in the pathogenesis of rheumatoid arthritis (RA), we phenotypically defined human CD4+ T cells as functionally distinct subsets, and analyzed the distribution and characteristics of each subset in the peripheral blood. We classified CD4+ T cells into six novel subsets based on the expression of CD45RA, CCR7, CD27, and CD28. The CCR7 + CD45RA-CD27 + CD28+ TCM subset comprised a significantly smaller proportion of CD4+ T cells in RA patients compared to healthy controls. The frequency of TNF-α-producing cells in the CCR7-CD45RA-CD27 + CD28+ TEM subset was significantly increased in RA. Furthermore, within the CCR7 + CD45RA-CD27 + CD28+ TCM subset, which was decreased in periperal blood from RA, the proportions of total Foxp3+ Treg cells and CD45RA-Foxp3(high) activated/effector Treg cells were significantly lower in RA patients. Our findings suggest that the increased proportion of TNF-α-producing cells and the decreased proportion of CD45RA-Foxp3(high) activated/effector Treg cells in particular subsets may have critical roles in the pathogenesis of RA.

Abstract
Exposure to polychlorinated biphenyls (PCBs) during pre-natal and early life can alter normal immune system development. Blood specimens from newborns, 6-, and 16-month-old infants were collected in the Michalovce and Svidnik/Stropkov districts, areas with, respectively, high and low environmental PCB contamination, and lymphocyte receptor expression was evaluated by multi-color flow cytometry. The results indicate that the percentage of lymphoid dendritic cells (DC) and naïve/resting T-lymphocytes were significantly increased at 6-months in Michalovce as compared to the same cell types in cord blood samples (p < 0.001), whereas natural regulatory T-lymphocytes and suppressor inducer T-lymphocytes were reduced (p < 0.001). Overall, a positive linear correlation of terminally differentiated effector memory (TEM) T-lymphocyte population with age, but a negative linear correlation for myeloid DC from birth to 6-months in both regions were found. Michalovce samples indicated significantly higher expression of memory T-lymphocytes (birth, 6(th), and 16(th) month), TEM T-lymphocytes (birth and 6(th) month), and lymphoid DC (6(th) month) compared to the Svidnik/Stropkov regions. After adjustment for relevant covariates, such as maternal age, parity, season of birth, breastfeeding, birth weight, and gender, the myeloid DC, suppressor inducer T-lymphocytes, truly naïve helper/inducer T-lymphocytes, and TEM T-lymphocytes remained significantly different between districts in cord blood samples. The multivariate analysis models for 6- and 16-month samples showed district differences in all cellular determinants, except for lymphoid DC and macrophage-like cells. This study provides the first evidence that pre-natal and early post-natal exposure to PCBs affects the dynamics of cell surface receptor expression on lymphoid DC and DC-like cells, suggesting impaired immunologic development following pre-natal and early post-natal PCB exposure.

Abstract
OBJECTIVES A small pool of long-lived memory CD4 T cells harboring the retroviral genome is one main obstacle to HIV eradication. We tested the impact of the gold compound, auranofin, on phenotype and viability of CD4 T cells in vitro, and on persistence of lentiviral reservoir cells in vivo. DESIGN In-vitro and in-vivo study. The pro-differentiating effect of auranofin was investigated in human primary CD4 T cells, and its capacity to deplete the viral DNA (vDNA) reservoir was tested in a pilot study involving six SIVmac251-infected macaques with viral loads stably suppressed by antiretroviral therapy (ART) (tenofovir/emtricitabine/raltegravir). The study was then amplified by intensifying ART using darunavir/r and including controls under intensified ART alone. All therapies were eventually suspended and viro-immunological parameters were monitored over time. METHODS Cell subpopulations were quantitated by flow cytometry following proper hematological analyses. Viral load and cell-associated vDNA were quantitated by Taqman real-time PCR. RESULTS In naïve, central memory and transitional memory CD4 T cells, auranofin induced both phenotype changes and cell death which were more pronounced in the memory compartment. In the pilot study in vivo, auranofin transiently decreased the cell-associated vDNA reservoir in peripheral blood. When ART was intensified, a sustained decrease in vDNA was observed only in auranofin-treated monkeys but not in controls treated with intensified ART alone. After therapy suspension, only monkeys that had received auranofin showed a deferred and subsequently blunted viral load rebound. CONCLUSION These findings represent a first step towards a remission of primate lentiviral infections.

Abstract
Because the synthesis of pro-inflammatory cytokines and apoptosis of lymphoid cells can be induced through P2X(7), we decided to study its expression, function (apoptosis, shedding of CD62L and synthesis of IL-1beta induced by ATP) and genetic polymorphisms (1513 AC and -762 T/C) in peripheral blood mononuclear cells from 101 patients with systemic lupus erythematosus (SLE), 122 with rheumatoid arthritis (RA) and 90 healthy controls. We found no significant differences in the distribution of 1513 and -762 genotypes of P2X(7) gene in SLE or RA patients compared with healthy controls. However, a diminished induction of apoptosis of CD4(+) T lymphocytes and monocytes was observed in SLE patients with the 1513 AC genotype, and the release of IL-1beta upon stimulation with ATP was significantly decreased in SLE patients. In contrast, in RA patients we detected that the release of IL-1beta was increased. In addition, in patients with SLE and RA the SNPs 1513 AC was associated with a low expression of P2X(7). These results suggest a possible involvement of P2X(7) in the pathogenesis of inflammatory autoimmune diseases.

Abstract
CTLA-4 is a critical gatekeeper of T-cell activation and immunological tolerance and has been implicated in patients with a variety of autoimmune diseases through genetic association. Since T cells from patients with the autoimmune disease systemic lupus erythematosus (SLE) display a characteristic hyperactive phenotype, we investigated the function of CTLA-4 in SLE. Our results reveal increased CTLA-4 expression in FOXP3(-) responder T cells from patients with SLE compared with other autoimmune rheumatic diseases and healthy controls. However, CTLA-4 was unable to regulate T-cell proliferation, lipid microdomain formation and phosphorylation of TCR-zeta following CD3/CD28 co-stimulation, in contrast to healthy T cells. Although lupus T cells responded in vitro to CD3/CD28 co-stimulation, there was no parallel increase in CTLA-4 expression, which would normally provide a break on T-cell proliferation. These defects were associated with exclusion of CTLA-4 from lipid microdomains providing an anatomical basis for its loss of function. Collectively our data identify CTLA-4 dysfunction as a potential cause for abnormal T-cell activation in patients with SLE, which could be targeted for therapy.

Abstract
OBJECTIVE The objective of this study was to investigate the efficacy of mesenchymal stem cell (MSC) in the treatment of arthritis. METHODS Mesenchymal stem cells were injected intravenously into mice with collagen-induced arthritis (CIA). Arthritic indexes were evaluated, and the levels of the pro- and anti-inflammatory cytokines interleukin-10 (IL-10), gamma interferon (IFN-gamma)-inducible protein 10 (IP-10), chemokine (C-X-C motif) receptor 3 (CXCR3), interleukin-17A (IL-17A), and tumor necrosis factor alpha (TNF-alpha) in serum or splenic cells were determined using real-time RT-PCR, Western blotting, and enzyme-linked immunosorbent assay (ELISA). The proliferation of dendritic cell line D2SC cells was determined using (3)H-TdR incorporation assay. RESULTS Upon injection of MSCs, overall arthritis symptoms were significantly improved in the CIA mouse models as indicated by the paw edema. Consistent with this observation, serum levels of pro-inflammatory cytokine TNF-alpha and inflammatory cell infiltration decreased significantly 12 days after MSC injection, while the expression of anti-inflammatory cytokines IL-10, IP-10, and CXCR3 was increased in splenocytes. In addition, we provided evidence that MSCs may directly promote the proliferation of D2SC cells and the expression of IP-10 in D2SC cells in vitro. CONCLUSION Mesenchymal stem cells significantly enhance the efficacy of collagen-induced arthritis treatment, likely through the modulation of the expression of various cytokines.

Abstract
Response to immunosuppressive therapy (IST) in younger patients with myelodysplastic syndrome (MDS) has been linked to a T-cell-dominant autoimmune process that impairs hematopoiesis. Analysis of the age-adjusted CD4:CD8 ratio in 76 MDS patients compared with 54 healthy controls showed that inadequate CD4+, rather than expansion of CD8+ T cells, was associated with a lower ratio in a group that included both lower and higher risk MDS patients defined by the International Prognostic Scoring System. In younger MDS patients, naive and memory phenotypes defined by CD45RA and CD62L display showed depletion of naive CD4+ and CD8+ T cells, suggesting a possible relationship to IST responsiveness. To determine the correlation between T-cell subset distribution, T-cell turnover and autoimmunity, a cohort of 20 patients were studied before and after IST. The CD4:CD8 ratio correlated inversely with the proliferative T-cell index before treatment in IST-responsive patients, suggesting that proliferation may be linked to accelerated CD4+ T-cell turnover and hematopoietic failure. Our data show seminal findings that both CD4+ and CD8+ T-cell subsets are dysregulated in MDS. Association between these T-cell defects and response to IST suggests that aberrant T-cell homeostasis and chronic activation are critical determinants influencing autoimmune hematopoietic suppression in younger patients.

Abstract
The study was aimed to investigate whether quantities of CD8(+) T cell subsets are normal in juvenile idiopathic arthritis (JIA) patients with disease remission compared to age-matched healthy donors (HD) and whether chronological age may have an impact on proportions of naive CD8(+) T cells. CD8(+) T cell subsets were analyzed in 17 JIA patients and 32 age-matched HD by flow cytometry. JIA patients showed lower CD3(+)CD8(+) T cells compared to HD. Total counts of CD8(+)CD28(+) and CD8(+)CD28(+)CD45RA(+) T cells were inversely correlated to chronological age in JIA patients and HD. In JIA patients, percentages of CD8(+)CD28(+)CD45RA(+) T cells and of CD62L-expressing CD8(+)CD28(+)CD45RA(+) T cells showed a negative correlation with age. The trend to lower CD28(+)CD45RA(+) T cell proportions in aged JIA patients in remission may reflect a disturbed T cell homeostasis independently of disease activity and may be due to an intrinsic effect in reconstitution of the peripheral T cells.

Abstract
Naïve and memory B- and T-cell subsets were examined with three-color flow cytometry in the peripheral blood of patients with rheumatoid arthritis (RA) in comparison with healthy controls, and their association with disease duration, activity and autoantibodies was investigated in order to reveal potential imprints of antigen-specific immune response in RA. The B-cell population consisted of significantly less naïve (58.1+/-3.9% versus 68.7+/-3.7%; p=0.04), and more IgD-/CD27+ memory B cells (19.6+/-2.1% versus 13.7+/-2.1%; p=0.04) compared to healthy subjects. In addition, strong correlation was demonstrated between disease duration and the percentage of memory B cells (p<0.0001). Increased CD8+ terminally differentiated effector memory/central memory T-cell ratio (1.35+/-0.35 versus 0.84+/-0.24) was also detected in RA patients compared with controls, which also correlated with the duration of RA (p=0.005). The frequency of memory B cells and CD8+ effector memory T cells correlated with the proportion of CD4+ effector memory lymphocytes, suggesting cooperation between immune cells. Our results reflect disturbances in B- and T-cell homeostasis characterized by the accumulation of memory B cells and a shift towards CD8+ terminally differentiated effector memory T cells in RA, suggesting ongoing, antigen-driven immune response and accelerated differentiation of B and T lymphocytes into effector cells.

Abstract
In hepatitis C virus (HCV) infection the immune response is ineffective, leading to chronic hepatitis and liver damage. Primed CD8 T cells are critical for antiviral immunity and subsets of circulating CD8 T cells have been defined in blood but these do not necessarily reflect the clonality or differentiation of cells within tissue. Current models divide primed CD8 T cells into effector and memory cells, further subdivided into central memory (CCR7+, L-selectin+), recirculating through lymphoid tissues and effector memory (CCR7-, L-selectin-) mediating immune response in peripheral organs. We characterized CD8 T cells derived from organ donors and patients with end-stage HCV infection to show that: 1) all liver-infiltrating CD8 T cells express high levels of CD11a, indicating the effective absence of naive CD8 T cells in the liver. 2) The liver contains distinct subsets of primed CD8+ T cells including a population of CCR7+ L-selectin- cells, which does not reflect current paradigms. The expression of CCR7 by these cells may be induced by the hepatic microenvironment to facilitate recirculation. 3) The CCR7 ligands CCL19 and CCL21 are present on lymphatic, vascular, and sinusoidal endothelium in normal liver and in patients with HCV infection. We suggest that the recirculation of CCR7+/L-selectin- intrahepatic CD8 T cells to regional lymphoid tissue will be facilitated by CCL19 and CCL21 on hepatic sinusoids and lymphatics. This centripetal pathway of migration would allow restimulation in lymph nodes, thereby promoting immune surveillance in normal liver and renewal of effector responses in chronic viral infection.

Abstract
Chronic graft-versus-host disease (cGVHD) remains a problematic complication of allogeneic hematopoietic stem cell transplantation. Laboratory parameters correlated with cGVHD have not been fully defined, although changes in CD4/CD8 ratios occur and a decrease in CD4(+) central memory T cells has been noted. Extracorporeal photopheresis (ECP) is an effective therapy for steroid-refractory cGVHD. We have noted changes in lymphocyte subsets after ECP. CD4(+) and CD8(+) T-cell central and effector memory populations were enumerated by flow cytometry in a cohort of 37 patients postallogeneic transplantation with symptomatic cGVHD. Of the patients with symptomatic cGVHD, 7 were treated with ECP over 6 months and prospectively assessed for changes in lymphocyte subsets. There was a highly significant correlation of an increase in CD8(+) central memory cells and a concomitant decrease in CD4(+) central memory cells in patients with symptomatic cGVHD. These changes were not detected in patients without cGVHD posttransplantation. In all, 7 patients with cGVHD followed up prospectively during ECP treatment showed a statistically significant normalization of the pattern of CD4(+) and a trend toward normalization of CD8(+) central memory T cells coincident with improvement of cGVHD. These data indicate a high correlation between disturbances in the balance of central and effector memory populations and cGVHD suggesting use in following up responses to therapy. The normalization of central and effector memory populations in response to ECP coincident with clinical improvement of cGVHD support a correlation between these laboratory parameters and cGVHD. Further studies are needed to demonstrate whether laboratory measurements of the magnitude of changes in central and effector memory populations are useful prognostically or can be used to guide response to therapy. The contrasting change in central memory cells (CD8(+) increased versus CD4(+) decreased) in cGVHD provide support for recent reports suggesting unique differences in the differentiation pathways for CD8(+) versus CD4(+) T cells.

Abstract
BACKGROUND/AIMS A dysregulated immune response has been suggested to be important for the pathogenesis of chronic pancreatitis (CP). Formation of immunological memory is based on the differentiation of naive T lymphocytes to memory T lymphocytes after exposure to antigens and specific cytokines. The aim of this study was to analyze peripheral blood mononuclear cells (PBMCs) in patients with CP for different T lymphocyte subsets including naive and memory T cells. METHODS PBMCs from 9 patients who had undergone pancreatic resection due to CP, 9 CP patients who had not been resected and 9 healthy controls were analyzed by flow cytometry. RESULTS Patients with CP had a skewed distribution of T lymphocytes, with an increased level of CCR7+/CD45RA- central memory T lymphocytes compared to healthy controls. Nonresected CP patients and subjects who had undergone pancreatic resection due to CP had similar levels of central memory T lymphocytes. CONCLUSION Our results indicate that the dysregulation of the immune system in chronic pancreatitis seems to persist even after removal of large parts of the local inflammatory site. We suggest that the increase of central memory T lymphocytes may be important for maintaining the inflammatory process in chronic pancreatitis.

Abstract
There is a well-recognized but unmet need for biological markers to characterize disease type, status, progression, and response to therapy in autoimmune diseases. We are developing and applying an integrated bioanalytical platform and clinical research program to facilitate comprehensive differential phenotyping of patient samples and enable the discovery of biomarkers. Our measurement platform includes microvolume laser scanning cytometry for the quantification of hundreds of cellular parameters in whole blood and other samples, liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry for the quantification of proteins and low molecular weight biomolecules in serum and other fluids or tissues, and specific immunoassays for the quantification of trace proteins in serum. We describe the technologies and discuss initial applications to the analysis of subjects with rheumatoid arthritis (RA) and healthy controls.

Abstract
Inflamed synovium of rheumatoid arthritis (RA) has been associated with a T helper (Th)1 cytokine profile but the blood situation remains to be clarified. We studied the differential IFN-gamma producing activity of peripheral blood mononuclear cells (PBMCs) from RA patients (RA-PBMCs) and from healthy controls (H-PBMCs) in response to IL-12 and IL-18. RA-PBMCs had a decreased IFN-gamma production in response to IL-12 and IL-18 when compared with H-PBMCs. RA-PBMCs activated with phytohemagglutinin and phorbol 12-myristate 13-acetate showed an increased sensitivity to IL-12 and IL-18, but still the RA-PBMC response was lower. IL-18 increased IL-12-stimulated IFN-gamma production from RA synovium cells obtained after collagenase digestion more effectively than that of RA- or H-PBMCs. A specific inhibitor of IL-18 bioactivity, IL-18-binding protein (IL-18BP), down-regulated IL-12-induced IFN-gamma production by RA- or H-PBMCs and had a remarkable effect on RA synovium cells. In conclusion, RA disease combines a polarized immune response with an active Th1 in inflamed joints and a reduced Th1 pattern in peripheral circulation.
