Abstract
Adipose tissue homeostasis relies on the interplay between several regulatory lineages, such as type 2 innate lymphoid cells (ILC2s), T helper 2 (Th2) cells, regulatory T cells, eosinophils, and type 2 macrophages. Among them, ILC2s are numerically the dominant source of type 2 cytokines and are considered as major regulators of adiposity. Despite the overlap in immune effector molecules and sensitivity to alarmins (thymic stromal lymphopoietin and interleukin-33) between ILC2s and resident memory Th2 lymphocytes, the role of the adaptive axis of type 2 immunity remains unclear. We show that mice deficient in CD27, a member of the tumor necrosis factor receptor superfamily, are more resistant to obesity and associated disorders. A comparative analysis of the CD4 compartment of both strains revealed higher numbers of fat-resident memory Th2 cells in the adipose tissue of CD27 knockout mice, which correlated with decreased programmed cell death protein 1-induced apoptosis. Our data point to a non-redundant role for Th2 lymphocytes in obesogenic conditions.

Abstract
Uveal melanoma represents an aggressive tumor that responds mostly poorly to established melanoma treatments. Comprehensive methylation profiling of the next-generation immunotherapeutic target genes, for example, members of the tumor necrosis factor receptor superfamily, might allow for the development of companion predictive biomarkers. We have analyzed CpG sites within the immune checkpoint genes GITR, OX40, 4-1BB, CD 27, and CD40 probed by the Illumina Infinium HumanMethylation450 BeadChip in N = 80 uveal melanomas included in The Cancer Genome Atlas with regard to BAP1 aberrancy, mRNA expression, and overall survival. In all analyzed immune checkpoint genes, BAP1 aberrancy was associated with decreased CpG methylation levels. We identified specific CpG sites that significantly correlated with BAP1 aberrancy, mRNA expression levels, and overall survival. Our results suggest epigenetic regulation of the analyzed immune checkpoint genes via DNA methylation in uveal melanoma and provide rationale for methylation testing in biomarker programs in clinical trials.

Abstract
Natalizumab and fingolimod are effective multiple sclerosis (MS) therapies that disrupt lymphocyte migration but have differential effects on B cell maturation and trafficking. We investigated their effects on peripheral blood (PB) and cerebrospinal fluid (CSF) B cell repertoires using next-generation deep sequencing. Paired CSF and PB B cell subsets (naïve, CD27+ memory, and CD27-IgD- double-negative B cells and plasmablasts) were collected by applying flow cytometry at baseline and after 6 months of treatment and their respective heavy-chain variable region repertoires assessed by Illumina MiSeq. Treatment with fingolimod contracted, whereas natalizumab expanded circulating PB B cells. CSF B cell numbers remained stable following fingolimod treatment but decreased with natalizumab therapy. Clonal overlap between CSF and PB B cells was reduced with natalizumab treatment but remained stable with fingolimod therapy. Lineage analyses of pre- and posttreatment CSF B cell repertoires revealed large, clonally expanded B cell clusters in natalizumab-treated MS patients but no intrathecal clonal expansion following fingolimod therapy. Our findings suggest that natalizumab diminishes the exchange of peripheral and intrathecal B cells without impacting intrathecal clonal expansion. In contrast, fingolimod treatment fails to alter blood-brain barrier B cell exchange but diminishes intrathecal clonal expansion. Sphingosine-1 phosphate receptor inhibition may alter intrathecal B cell biology in MS.

Abstract
Human immunodeficiency virus type 1 (HIV-1) infection causes apoptosis of infected CD4 T cells as well as uninfected (bystander) CD4 and CD8 T cells. It remains unknown what signals cause infected cells to die. We demonstrate that HIV-1 protease specifically cleaves procaspase 8 to create a novel fragment termed casp8p41, which independently induces apoptosis. casp8p41 is specific to HIV-1 protease-induced death but not other caspase 8-dependent death stimuli. In HIV-1-infected patients, casp8p41 is detected only in CD4(+) T cells, predominantly in the CD27(+) memory subset, its presence increases with increasing viral load, and it colocalizes with both infected and apoptotic cells. These data indicate that casp8p41 independently induces apoptosis and is a specific product of HIV-1 protease which may contribute to death of HIV-1-infected cells.

Abstract
Differentiation of naïve B cells into plasma cells or memory cells occurs in the germinal centers (GCs) of lymph follicles or alternatively via a GC- and T-cell-independent pathway. It is currently assumed that B-cell lymphomas correlate to normal B-cell differentiation stages, but the precise correlation of several B-cell lymphomas to these two pathways remains controversial. In the present report, we describe the junctional adhesion molecule C (JAM-C), currently identified at the cell-cell border of endothelial cells, as a new B-cell marker with a tightly regulated expression during B-cell differentiation. Expression of JAM-C in tonsils allows distinction between two CD27+ B-cell subpopulations: JAM-C- GC B cells and JAM-C+ non-germinal B cells. The expression of JAM-C in different B-cell lymphomas reveals a disease-specific pattern and allows a clear distinction between JAM-C- lymphoproliferative syndromes (chronic lymphocytic leukemia, mantle cell lymphoma and follicular lymphoma) and JAM-C+ ones (hairy cell leukemia, marginal zone B-cell lymphoma). Therefore, we propose JAM-C as a new identification tool in B-cell lymphoma diagnosis.

Abstract
Dietary supplementation with polyunsaturated fatty acids (PUFAs), especially those of the n-3 class, has immunosuppressive effects on both innate and adaptive immunity through various mechanisms. In this review, we focus on the PUFA modulation of membrane architecture and its consequent effects on both T cell responses and antigen presentation. We first use data from in vitro and in vivo experiments to make the case that the immunosuppressive effects of PUFAs begin with membrane incorporation and modulation of lipid-protein lateral organization. This in turn inhibits downstream signaling mediated by T cell receptors and suppresses T cell activation and proliferation. Next, we review evidence for PUFA-mediated alteration of major histocompatibility complex class I and II surface expression and antigen presentation. We propose that PUFAs influence the expression of major histocompatibility complex by altering its conformation, orientation, lateral organization, and trafficking, with consequences for recognition by effector T cells. Finally, we present data from model membrane studies to explain the physical principles that make PUFA acyl chains unique in modifying membrane lateral organization and protein function. An important concept to emerge from these studies is that PUFA acyl chains and cholesterol molecules are sterically incompatible. By applying this concept to the T cell activation and signaling model, mechanisms emerge by which PUFAs can modulate membrane lipid-protein lateral organization. Our data-based models show that membrane modification of both effectors and targets is an important, often overlooked, mechanism of immunomodulation by PUFAs.

Abstract
Unmethylated CpG DNA activation of naive CD27- B cells has been reported to require B-cell-receptor (BCR) cross-linking. We describe a culture system using CpG DNA with sequential steps for T-cell-independent activation of naive CD19+CD27- human peripheral blood B cells that induces efficient CD138+ plasma-cell differentiation. CD27+ and CD27- B cells were cultured in a 3-step system: (1) days 0 to 4: CpG, IL-2/10/15; (2) days 4 to 7: IL-2/6/10/15 and anti-CD40L; (3) days 7 to 10: IL-6/15, IFN-alpha, hepatocyte growth factor, and hyaluronic acid. Both CD27+ and CD27- B cells up-regulated intracytoplasmic TLR-9 following CpG DNA activation. CD27- B-cell activation required cell-cell contact. Both naive and memory B cells progressed to a plasma-cell phenotype: CD19lowCD20lowCD27+CD38+HLA-DRlow. Seventy percent of the CD27--derived CD138+ cells demonstrated productive V chain rearrangements without somatic mutations, confirming their origin from naive precursors. Plasma cells derived from CD27+ B cells were primarily IgG+, while those from CD27- B cells were IgM+. Our results indicate that under certain conditions, naive B cells increase TLR-9 expression and proliferate to CpG DNA stimulation without BCR signaling. In addition to its immunologic significance, this system should be a valuable method to interrogate the antigenic specificity of naive B cells.

Abstract
AbstractThe immunosuppressive drugs rapamycin and cyclosporin A (CsA) are widely used to prevent allograft rejection. Moreover, they were shown to be instrumental in experimental models of tolerance induction. However, it remains to be elucidated whether these drugs have an effect on the CD4+CD25+ regulatory T-cell (TREG) population, which plays an important role in allograft tolerance. Recently, we reported that alloantigen-driven expansion of human CD4+CD25+ TREGs gives rise to a distinct highly suppressive CD27+TREG subset next to a moderately suppressive CD27-TREG subset. In the current study we found that rapamycin and CsA do not interfere with the suppressive activity of human naturally occurring CD4+CD25+ T cells. However, in contrast to CsA, rapamycin preserved the dominance of the potent CD27+TREG subset over the CD27-TREG subset after alloantigen-driven expansion of CD4+CD25+ TREGs in vitro. Accordingly, CD4+CD25+ TREGs cultured in the presence of rapamycin displayed much stronger suppressive capacity than CD4+CD25+ TREGs cultured in the presence of CsA. In addition, CD4+CD25+ TREG cells cultured in the presence of rapamycin, but not CsA, were able to suppress ongoing alloimmune responses. This differential effect of rapamycin and CsA on the CD27+TREG subset dominance may favor the use of rapamycin in tolerance-inducing strategies.

Abstract
OBJECTIVE Functional recovery of B lymphocytes after hematopoietic stem cell transplantation (HSCT) can take up to 2 years. HSCT recipients may obtain protective titers of pathogen-specific antibody through vaccination, but optimal timing of reimmunization remains to be defined. PATIENTS AND METHODS In this study, we evaluated the reconstitution of B-cell number and activity in 139 children given HSCT, by B-cell subset phenotyping and in vitro immunoglobulin (Ig) production. RESULTS Patients were longitudinally studied at 3, 6, 12, and 18 to 24 months after transplantation. At all time points, recipients displayed a significantly higher percentage of naive (IgD+CD27-) B cells and showed significantly lower production of stimulated in vitro Ig as compared to healthy controls. Moreover, during follow-up, we observed an increase in the proportion of patients who had CD27+ B subsets and who were able to mount in vitro Ig production greater than the 5th percentile. CONCLUSION Similar to what has been described in adults, most children lack memory B cells and produce low amounts of Ig. However, the number of B cells, as well as their function, gradually recovered over time and the spread of data we observed suggests that the reimmunization schedule should be individualized for each patient. It remains to be defined in a prospective clinical study the time point at which a patient should start reimmunization. A reasonable hypothesis to be explored is the time point at which a percentage of memory B cells greater than the 5th percentile of normal controls is reached.

Abstract
The human peripheral B-cell compartment displays a large population of immunoglobulin M-positive, immunoglobulin D-positive CD27(+) (IgM(+)IgD(+)CD27(+)) "memory" B cells carrying a mutated immunoglobulin receptor. By means of phenotypic analysis, complementarity-determining region 3 (CDR3) spectratyping during a T-independent response, and gene-expression profiling of the different blood and splenic B-cell subsets, we show here that blood IgM(+)IgD(+)CD27(+) cells correspond to circulating splenic marginal zone B cells. Furthermore, analysis of this peripheral subset in healthy children younger than 2 years shows that these B cells develop and mutate their immunoglobulin receptor during ontogeny, prior to their differentiation into T-independent antigen-responsive cells. It is therefore proposed that these IgM(+)IgD(+)CD27(+) B cells provide the splenic marginal zone with a diversified and protective preimmune repertoire in charge of the responses against encapsulated bacteria.

Abstract
Viable Lin(-) CD27(+) c-kit(Hi) Sca-1(Hi) GFP(+) cells recovered from heterozygous RAG1/GFP knockin mice progressed through previously defined stages of B, T, and NK cell lineage differentiation. In contrast to the GFP(-) cohort, there was minimal myeloid or erythroid potential in cells with an active RAG1 locus. Partial overlap with TdT(+) cells suggested that distinctive early lymphocyte characteristics are not synchronously acquired. Rearrangement of Ig genes initiates before typical lymphoid lineage patterns of gene expression are established, and activation of the RAG1 locus transiently occurs in a large fraction of cells destined to become NK cells. These early lymphocyte progenitors (ELP) are distinct from stem cells, previously described prolymphocytes, or progenitors corresponding to other blood cell lineages.

Abstract
Conflicting results obtained from animal studies suggest that B cells play a role in maintaining long-term T-cell memory and in skewing T-cell response toward a T-helper 2 (T(H)2) phenotype. X-linked agammaglobulinemia (XLA) is a genetic human disease characterized by the lack of circulating B cells due to the mutation of Bruton tyrosine kinase. This disease thus represents a unique model for studying the role of B lymphocytes in regulating T-cell functions in humans. To this aim, we analyzed hepatitis B envelope antigen (HBenvAg)-specific T-cell memory in a series of XLA patients vaccinated against hepatitis B virus (HBV). We found HBenvAg-specific T lymphocytes producing interferon-gamma, interleukin-4, or both in the peripheral blood of XLA patients up to at least 24 months after completing the standard anti-HBV immunization protocol. The HBenvAg-specific T-cell frequencies and the percentage of patients with these responses were not significantly different from healthy vaccinated controls. By combining cell purification and enzyme-linked immunospot assay, we found that effector CD27- T cells, which promptly produced cytokines in response to antigen (Ag), and memory-resting CD27+ T cells, which required Ag restimulation to perform their functions, were maintained in both XLA patients and controls for up to 24 months after the last vaccination boost. These data strongly suggest that B cells are not an absolute requirement for the generation of effective T-cell memory in humans, nor do they seem to influence T(H)1/T(H)2 balance.

Abstract
This review focuses on the properties and roles of distinct subsets among the primary and the memory B lymphocytes regarding their contribution to helper-T-cell-dependent and -independent antibody responses. The naive/memory B cell functions are explained in the context of current concepts on the basic mechanisms of humoral immunity. Differences between murine and human B cells are also discussed.

Abstract
Pancreatic cancer remains one of the most difficult cancers to treat; very few effective therapies are available, with surgery being the sole chance for cure-yet surgery is not a viable option for most pancreatic cancer patients. Immunotherapy has the potential to provide a non-cross-resistant mechanism of antitumor activity that can be integrated with surgery, radiation therapy, and chemotherapy. However, the inherent instability of the tumorgenome as well as tumor tolerance mechanisms are significant practical obstacles that must be overcome if immune-based approaches for pancreatic cancer can achieve its promise. Recent advances in both tumor immunology and vaccine design have already resulted in promising preliminary data from phase I studies, and additional trials are already in progress. This article summarizes some of the progress and challenges in immunotherapy research.

Abstract
In response to viral infection, unprimed naive CD8(+), major histocompatibility complex class I-restricted, virus-specific T cells clonally expand and differentiate into memory- and effector-type cells. Changes in CD8(+) subset distribution were studied in 17 subjects with acute human immunodeficiency virus type 1 infection and in 14 subjects with acute Epstein-Barr virus (EBV) infection, with combined CD45RO, CD27, and CD28 monoclonal antibodies. A vast expansion of memory-type CD45RO(+)CD27(+)CD8(+) T cells, with high expression of the cell-cycle marker Ki-67, was observed in both infections. Strikingly, CD45RO(+)CD27(+)CD28(-) cells increased >10-fold in acute viral infection and had high Ki-67 expression. In acute EBV infection, a substantial portion of the expanded T cells were EBV-peptide specific. These cells resided mainly in the CD45RO(+)CD27(+) subpopulation, with most in the CD27(+)CD28(-) subpopulation. Content of perforin expression, as a measure of cytotoxic capacity, was relatively low in the CD27(+)CD28(+) T cells and highest in the CD27(-)CD28(-) subpopulation.

Abstract
Recent progress in the definition of molecules involved in immune regulation has led to the discovery of a number of type I membrane glycoproteins with a distinctive, cysteine-rich, repetitive domain structure within their extracellular regions. Because the prototype members of this family are receptors for cytokines (tumor necrosis factor [TNF] and nerve growth factor [NGF]), it was expected that the ligands for the other receptors would possess cytokine-like activities. This prediction has been fulfilled by the cloning of cDNA encoding a series of type II membrane glycoproteins, with homology to TNF, that bind to, and signal through, their cognate receptors. While the biological role of some of these ligand-receptor pairs remains obscure, at least two members of the family, CD40 and Fas, have proven their importance. The human X-linked immunodeficiency, hyper IgM syndrome, is the result of mutations in the CD40 ligand gene, and the Fas and Fas ligand genes are mutated in two mouse strains, lpr and gld, that develop autoimmune disease. These findings, together with other evidence, point to key roles of CD40/CD40 ligand interactions in immune activation, particularly in T-dependent B cell responses, and of Fas/Fas ligand in apoptosis and peripheral tolerance. These molecules, as well as the other ligands of the family, share the property of costimulation of T cell proliferation and are all expressed by activated T cells. More detailed analysis of the expression patterns of ligands and receptors on lymphocyte subpopulations will be necessary to define their different roles in immune activation and suppression.

Abstract
We have characterized the activation state of T cells in the bronchoalveolar lavage fluid (BALF) and peripheral blood (PB) from patients with sarcoidosis, to obtain more information about their mechanisms of activation. We analyzed the expression of activation markers (CD25, HLA-DR, Leu-8, and two recently defined markers, CD69 and CD27) on T cells by two-color flow cytometry. We also measured the levels of soluble CD27 and soluble CD25 in nonconcentrated BALF and in serum by ELISA. We found that most T cells in BALF from patients, but not in the peripheral blood, expressed CD69, whereas they did not express CD27. The phenotype (CD69+CD27-) of most BALF T cells and the coexpression of CD69 with HLA-DR and/or VLA-1 indicates that they are in a state of recent and persistent activation. We confirmed previous findings of expression of CD25, HLA-DR, and Leu-8 by T lymphocytes in BALF from patients. We also confirmed increased levels of soluble CD25 in the serum from these patients. The levels of sCD27 and sCD25 in the epithelial lining fluid (ELF) were calculated on the basis of urea in BALF and serum. They were increased in the patients compared with control subjects. In both patients and control subjects, levels in ELF were higher than in the peripheral blood. This indicates shedding of sCD27 (and sCD25) in the lung compartment, which likely contributes to levels in the serum. It is known that in vitro CD27+ cells become CD27- after repeated stimulation and that CD27- cells, after restimulation, do not shed sCD27.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
CD27, a lymphocyte-specific member of the TNF/NGF-R family, is expressed on the majority of peripheral blood T cells. Activation of T cells via TCR/CD3 induces high CD27 surface expression and the release of a soluble extracellular part of the molecule. After prolonged activation in vitro, CD27 becomes gradually switched off. There is evidence that also in vivo, CD4+ cells that have persistently been stimulated by Ag, accumulate within the CD45RA-CD27- subset. In addition, an increase of CD27- T cells has been observed under certain immunopathologic conditions and during aging. This study was undertaken to analyze the regulation of CD27 on different T-cell subsets and to determine whether the loss of CD27 expression is an irreversible event and may thereby mark T-cell differentiation. In agreement with earlier findings, all CD4+CD45RA+CD45RO- T cells were found to express CD27, whereas a small fraction of the CD4+CD45RA-CD45RO+ subset lacks the molecule. In contrast, within the CD8+ compartment CD27- subsets were found both in the CD45RA+ and CD45RA- subpopulations. After stimulation with CD3 mAb, both CD27 membrane expression and release was equally up-regulated in CD4+ and CD8+ subpopulations. This stimulus, however, provoked a strikingly predominant up-regulation of membrane CD27 on CD45RO- cells as compared with CD45RA- cells. On CD4+CD45RA-CD27- T cells and long-term grown CD45RA-CD27- TLC, CD27 expression could not be reinduced after stimulation of the TCR/CD3 complex, neither at the protein nor at the mRNA level. Comparison of CD27 expression with its structural homologue FAS/APO-1 showed that down-regulation after prolonged activation is not a general feature of TNF/NGF-R family members. The CD27 ligand was recently identified and was shown to give a co-stimulatory signal to PHA-activated T cells. The restricted up-regulation of CD27 on CD45RA+ cells after T-cell stimulation may point at a discrete role of CD27-CD27 ligand interaction during transition of CD45RO- to CD45RA- T cells. In addition, the CD27 negative phenotype seems a stable reflection of differentiation rather than of activation.

Abstract
The interaction between encephalitogenic lymphocytes and the cerebral microvascular lining is considered to be an important initial step in the recruitment of immune cells into the central nervous system (CNS) under pathological conditions such as multiple sclerosis (MS) and its investigative analog, experimental allergic encephalomyelitis (EAE). This study was conducted in order to examine whether differences in microvascular endothelial cell expression of several molecules involved in lymphovascular interactions correlate with the strain and organ-specific development of EAE. Cerebral and epididymal microvascular endothelial cells (EC) were isolated from SJL and B10.S mice, which, despite MHC-compatibility (H-2S), differ in their ability to develop EAE. The subcultured cells were then analyzed by flow cytometry for their ability to express class I MHC, class II MHC and ICAM-1 molecules in response to treatment with murine recombinant interferon-gamma (IFN-gamma). Over a range of doses and times, cerebral EC cultures derived from EAE-susceptible SJL mice expressed two-fold higher levels and higher cell surface densities of class II molecules than cerebral EC cultures derived from EAE-resistant B10.S mice, whereas class I and ICAM-1 molecules were comparably upregulated on both SJL and B10.S cerebral EC. In contrast, both SJL and B10.S epididymal EC cultures expressed lower but comparable levels of class II molecules in response to IFN-gamma. Class I and ICAM-1 molecules, however, were upregulated to at least the same degree as that observed on cerebral EC derived from both strains.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Rat thymic dendritic cells have been isolated by collagenase digestion, separation of the low-density cell fraction by centrifugation on metrizamide, and differential adherence. The resulting dendritic cell preparation had a purity of > 90%, and has been analysed by flow cytometry (FCM) using a large panel of monoclonal antibodies (mAb). Dendritic cells expressed major histocompatibility (MHC) class I and class II molecules, the leucocyte common antigen CD45, the rat leucocyte antigen OX44, the rat macrophage marker ED1, and the adhesion molecules Mac-1, LFA-1 and ICAM-1. They were negative for the T- and B-cell-specific forms of CD45, CD45R and B220, and the B-cell marker OX12. Concerning T-cell marker expression, they were negative for T-cell receptor (TcR) and OX40, but they expressed CD2, CD4 and CD8, and interestingly, 50% of DC were CD5+, 50% expressed the alpha-chain of interleukin-2 receptor (IL-2R), and 80% were positive for the T-cell activation antigen recognized by the mAb OX48. Moreover, 60% of DC expressed high levels of Thy-1, whereas 40% displayed intermediate levels of this T-cell marker.

Abstract
CD27 is a surface antigen found on T and B cells that has homology to a family of molecules including the receptors for tumor necrosis factor (TNF) and nerve growth factor. A cDNA encoding a ligand for CD27 was isolated by a direct-expression cloning strategy using a fusion protein composed of the extracellular domain of CD27 linked to the constant domain of a human immunoglobulin G1 molecule as a probe. The predicted protein product is a type II transmembrane protein whose gene maps to 19p13 and that shows homology to TNF and the ligand for CD40. Biological characterization indicates that the cloned ligand induces the proliferation of costimulated T cells and enhances the generation of cytolytic T cells.

Abstract
The human CD4 population can be divided into functionally distinct and largely reciprocal subsets based on their differential expression of CD45 isoforms (CD45RA, CD45RO) and the CD29/VLA beta chain. CD4+CD45RO+ CD29high "memory" (helper inducer) cells respond maximally to recall antigens and provide help for B cell IgG synthesis. In contrast, the CD4+CD45RA+ CD29low "naive" (suppressor inducer) population responds poorly to recall Ag, lacks helper function for B cells, but can both induce CD8 cells to suppress B cell IgG synthesis and proliferate preferentially in an autologous mixed lymphocyte response (AMLR). The phenotypic "conversion" after activation and the preferential responsiveness of CD45RA-CD45RO+ CD29high cells to recall antigen led to the view that CD45RA+ cells are "naive" and immature and convert to CD45RA-CD45RO+ "memory" cells after activation. This conversion was believed by many to be unidirectional and irreversible. It has become increasingly clear that the naive-memory concept outlined above is far from settled and that naive CD4+CD45RA+ T cells retain their unique functional program after activation and are distinct from the freshly isolated CD4+CD45RO+ subset. Moreover, CD45RA is not irreversibly lost following activation, but in fact recycles on the cell surface. Given the problems with CD45 isoform expression as a definition of maturational state, we have investigated the possibility that more reliable cell surface molecules are needed which could delineate between the functions of activated CD45RA+ and CD45RA- CD45RO+ cells. We could show that CD31 and CD27 are preferentially expressed on the CD4+CD45RA+ subset of cells and their expressions are stably maintained on these cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
When cultured without appropriate growth factors, most of activated (CD45RO+) T cells expanded in acute EBV-induced infectious mononucleosis (IM) easily die via an apoptotic cell death mechanism, indicating one Ag-driven selection in the periphery. In this work, we attempted to raise the mAb against cell surface molecules, preferentially expressed on T cells entering apoptosis, by immunizing PBMC from an acute IM patient. We obtained one mAb, termed IMN3.1, that could define clearly the expansion of activated (CD45RO+) T cells in the blood of acute IM patients. In contrast to its intense expression on IM T cells, the IMN3.1-reactive Ag was only dimly expressed on CD45RO+ (memory or previously activated) populations of T cells from normal individuals. Although naive (CD45RO-) populations of T cells usually lacked IMN3.1 Ag, this Ag was inducible relatively late after in vitro activation of naive T cells. The cellular distribution and molecular characterization of IMN3.1-reactive Ag suggested that IMN3.1 mAb appeared to recognize a novel activation-associated cell surface determinant of about 120 kDa m.w., which might be predominantly expressed on apoptosis-prone T cell lineage cells, such as IM T cells, thymocytes, cytokine-dependent T cell lines, and anti-Fas-sensitive T cell lines.

Abstract
The liver regulates the supply of amino acids required for protein synthesis and intermediary metabolism between feeding and fasting in mammals. The flux of amino acids between the liver and other tissues is determined, in part, by the activity of specific carrier proteins. We have identified a carrier of the cationic amino acids arginine, lysine, and ornithine in mouse liver that is closely related to a previously identified transporter with the same substrate specificity expressed in nonhepatic tissues. Uptake studies were performed in Xenopus oocytes injected with cRNA encoding these proteins. The comparison of the two transporters in these studies demonstrated that, unlike the widely-expressed transporter, arginine uptake mediated by the liver carrier is significant only at substrate concentrations that exceed systemic plasma levels and is less dependent on the intracellular concentration of cationic amino acids. These properties enable hepatocytes expressing this carrier to remove excess cationic amino acids from the blood without interfering with their uptake by nonhepatic tissues that express the related transporter.

CD27 is a member of the nerve growth factor receptor family, that includes two types of tumor necrosis factor receptor, CD40 and Fas/Apo-1. Human CD27 has been found only on lymphocytes. In T cells, its expression strongly increases in a transient fashion upon antigenic stimulation, suggesting that CD27 plays a role during T cell activation. To analyze the function of CD27, we have identified the murine CD27 at the cDNA and protein level. Murine CD27 shows an identity of 65% compared with human CD27. The amino-terminal cysteine-rich region, i.e. the putative ligand-binding domain, and the carboxy-terminal part of the cytoplasmic domain are approximately 80% identical in man and mouse. Murine CD27 has 29% identity to 4-1BB, another lymphocyte-specific member of the receptor family defined only at the cDNA level. Murine CD27 and 4-1BB have 39% homology in the cysteine-rich domain and share a conserved region in the cytoplasmic tail. Expression studies identified murine CD27 mRNA in thymus and spleen, but not in non-lymphoid tissues, while 4-1BB mRNA was not detected in any tissue tested. In resting T cells, only murine CD27 mRNA was found, while in activated T cells murine CD27 as well as 4-1BB were present at high levels. Murine CD27 and 4-1BB mRNA are expressed with different kinetics during T cell activation, suggesting that these molecules play different roles in this process. Peptide antisera identified murine CD27 as a 45-kDa protein on thymocytes and activated T cells, while 4-1BB was precipitated as a 35-40-kDa protein from activated T cells.

Abstract
MRL/Mp-lpr/lpr (MRL/lpr) mice develop marked lymphadenopathy, characterized predominantly by Thy1+CD3+CD4-CD8- cells ("double negative T cells"; DNT). It is paradoxical that DNT proliferate poorly in vitro when stimulated through CD3 or by mitogens. The hamster mAb H1.2F3, raised against dendritic epidermal DNT, recognizes a very early activation (VEA) Ag, which is generally absent on resting cells but expressed soon after T cell activation with ConA or phorbol ester. Cross-linking of this disulfide-linked dimer in the presence of APC and phorbol ester induces proliferation of normal T cells. Therefore, we tested to see whether MRL/lpr DNT expressed this Ag and whether it might play a role in DNT expansion. Unmanipulated cells from enlarged MRL/lpr lymph nodes expressed VEA in an age-dependent manner, peaking at 3 to 4 mo of age. Only limited expression in a small subset of lymphocytes from the congenic MRL/Mp(-)+/+ strain was seen. VEA expression on freshly harvested MRL/lpr lymphocytes was seen mainly on DNT, yet double staining of the DNT for VEA Ag and three other markers known to be present on lpr DNT showed that the DNT were a heterogeneous population. In addition, some CD4+ T cells expressed VEA Ag. Despite their constitutive VEA Ag expression, MRL/lpr DNT showed no proliferative response to cross-linking with the H1.2F3 antibody. Furthermore, unlike normal T cells, they failed to respond to the antibody even when phorbol ester was added. The addition of supplementary cytokines did not correct this defect. These studies indicate that MRL/lpr DNT constitutively and aberrantly express VEA but do not respond when it is cross-linked. These abnormalities may result from the failure to express Fas, the recently reported apoptosis-inducing receptor defective in lpr mice.

Abstract
CD27 is a lymphocyte-specific member of a recently identified receptor family with at least 10 members that includes the receptors for nerve growth factor and TNF, CD40, and Fas. Several members of this family play a role in cell differentiation, proliferation, and survival. Within the amino terminal ligand binding domain of these receptors, repeat motifs have been identified. These repeats contain many cysteine residues in a conserved pattern, characteristic of this family. We have isolated and characterized the human CD27 gene to gain insight into the evolution of this type of receptor domain. The gene was localized on chromosome 12, band 12p13. Sequence analysis showed no correlation between the intron/exon organization and the subdivision of the protein into distinct domains. Structural information for the cysteine-rich domain is contained within three exons. In addition, the splice sites in the CD27 gene are located in a different position from those in the related nerve growth factor receptor gene. However, a comparison of the splice sites within the regions encoding the respective ligand-binding domains of the CD27 and nerve growth factor receptor genes identifies the archetypal cysteine-rich building blocks, from which the members of this family may have arisen during the course of evolution. From this observation, we propose a new organization of the repeat motifs.

Abstract
In lymphoid follicles, CD4+ T lymphocytes provide contact-dependent stimuli to B cells that are critical for the generation of specific antibody responses in a process termed Th function. The CD4+ T cell-restricted surface activation protein, 5c8 Ag (T-BAM), has recently been shown to be a component of the contact-dependent helper signal to B cells. To further dissect this process, we utilized a Jurkat T cell lymphoma clone, termed D1.1, that constitutively expresses T-BAM and activates peripheral B cells to express surface CD23 in a contact-dependent mechanism that is inhibited by mAb anti-T-BAM (5c8). Similar to its effect on peripheral B cells, Jurkat D1.1 activates B cells from lymphoid organs, as well as a B cell lymphoma clone, RAMOS 266,4CN 3F10 (RAMOS 266), to up-regulate surface CD23. Interestingly, mAb to the B cell surface molecule, CD40 (mAb G28-5 and B-B20), inhibit D1.1 induced activation of RAMOS 266 and peripheral and lymphoid B cells. In contrast, mAb to CR2 or the adhesion molecules, LFA1, LFA3, or ICAM-1, have little effect. The inhibitory effect of anti-CD40 mAb on B cell activation induced by D1.1 is specific because anti-CD40 potentiates, rather than inhibits, the up-regulation of CD23 on B cells induced by rIL-4. Moreover, cross-linking CD40 molecules by anti-CD40 mAb bound to Fc gamma RII+ (CD32) L cells induces B cell CD23 expression. In vivo, T-BAM-expressing cells are CD4+ T cells that are restricted to lymphoid organs and are localized in the mantle and centrocytic zones of lymphoid follicles and the spleen periarteriolar lymphoid sheath in association with CD40+ B cells. Taken together, these data demonstrate that T-BAM on T cells and CD40 on B cells are involved in contact-dependent T-B help interactions that occur in lymphoid follicles.

Abstract
CD27 is a disulfide-linked 120-kDa homodimer expressed on the majority of peripheral T cells at variable density that belongs to the recently defined nerve growth factor receptor family. mAb reactive with CD27 can either enhance or inhibit T cell activation, suggesting a crucial role in the process of T cell activation. We now show that CD27 is preferentially expressed on the CD45RA+CD45RO-CD29low subset of CD4 cells. CD27 expression on this subset is maintained for a prolonged period in culture after PHA activation. In contrast, CD45RA-CD45RO(+)-CD29high subset of CD4 cells express very low level of CD27, and its expression is lost within 2 wk after PHA activation. To further analyze the differential expression of CD27 on these reciprocal subsets of CD4 cells, we developed T cell clones by stimulating isolated CD4+CD45RA+ and CD4+CD45RO+ populations with PHA. T cell clones derived from cells originally CD45RA+ retained both CD45RA and CD27 expression, whereas T cell clones derived from cells originally CD45RO+ were CD45RA- and CD27-. In functional assays, IL-4 production could only be induced in CD45RA-CD27- CD4 clones by stimulation with PMA and ionomycin. Four of six CD45RA+ CD4 clones had suppressor activity in PWM-driven IgG synthesis, whereas five of six CD45RA- CD4 clones had helper activity. Of interest, the suppressor activity of CD45RA+CD27+ clones was partially blocked by pretreatment with anti-CD27 mAb (1A4). Anti-1A4 pretreatment of these T cell clones resulted in elevation of intracellular cAMP levels. Thus, CD27 appears to play a role in the function of CD45RA+CD27+ CD4 cells, and may be involved in suppressor activity of these cells at least in part via its effects on cAMP production.

Abstract
The obtained murine mAb LT27 (IgG2a) assigned to the cluster of differentiation CD27 was used to study the distribution of antigen CD27 among human lymphocytes scbpopulations in normal state and immunopathology. In normal donors the antigen CD27 was found to be expressed most frequently on CD4+ cells (90 +/- 8% of which coexpressed antigen CD27) and to the lesser extent on- CD8+ cells (only 77 +/- 28% of CD8+ cells carried antigen CD27). 79 +/- 12% of double negative lymphocytes (CD3+CD4-CD8-) expressed antigen CD27. In patients with hypogammaglobulinemia the proportion of CD4+CD27+/CD4+ and CD8+CD27+/CD8+ was significantly reduced to 80 +/- 11% (p < 0.01) and 45 +/- 19% (p < 0.001), respectively. The ratio CD4+CD27+/CD4+ varied insignificantly with the increase of CD4+ population, but the increase of the CD8+ population was accompanied by the definite tendency to a decrease of the ratio CD8+CD27+/CD8+. The distribution of CD27 antigen inside CD4+ and CD8+ subpopulations was found to be different from the distribution of CD29 and CD45RA antigens.

Abstract
The human CD45R0+ (memory) CD4+ T cell population can be subdivided into a large (82%) CD27+ and a small (18%) CD27- subset. Within the CD45R0+CD27- subset, cells accumulate that have been persistently stimulated by Ag in vivo. As an apparent consequence, TLC with a differentiated functional phenotype, producing either high levels of IFN-gamma (Th1-like), high levels of IL-4 (Th2-like) or high amounts of both these cytokines (here referred to as Thx) can primarily be generated from the CD27- memory CD4+ T cell subset. In this study we examined the requirements for induction of proliferation of distinct CD4+CD45R0+ Th subsets. Immobilized CD3 mAb induced proliferation with comparable magnitude and kinetics in all types of TLC. However, interference with intracellular signaling pathways in this activation system, resulted in a strong inhibition of proliferation in TLC derived from CD27+ cells whereas, in contrast, TLC from CD27- cells were relatively resistant to elevation of [cAMP]i, inhibition of protein kinase C activation and the immunosuppressive effects of cyclosporin A. Stimulation with CD3 mAb in soluble form resulted in Il-4 secretion by Th2-like and Thx-type TLC but did not induce IFN-gamma or Il-2 secretion in any Th subset. Interestingly, Th2-like cells but not Thx-type cells were able to use endogenously produced Il-4 for proliferation. These data demonstrate a differential sensitivity of CD45R0+CD4+ Th subsets for immune activation and suppression, which correlated with their maturation stage, as reflected by CD27 membrane expression, as well as with their effector phenotype.

Abstract
Current assays for chicken interleukin-2 (IL-2) utilize mitogen-activated lymphocytes. However, very high inter-assay variability and sporadic high background proliferation limit their usefulness. In view of the above, several Marek's disease virus (MDV)-transformed T-cell lines (which grow well in a serum-supplemented medium) were tested for a response to chicken IL-2 when grown in serum-free media. Five of six lines examined showed a dose-dependent proliferative response to chicken T-cell conditioned media. One line, MDCC-CU14, was chosen for further studies. In addition to the tumor cells' dose-dependent responses to semi-purified chicken IL-2, they expressed T-cell activation antigens on the cell surface. Furthermore, the level of surface expression was enhanced on cells provided IL-2. Co-incubation of the tumor cells with monoclonal antibody INN-CH-16 (specific for an antigen on the surface of activated T-cells) and IL-2 resulted in a modulation of lymphokine-induced proliferation. Together, these data suggest that signalling mechanisms in MDV T-cell tumors are intact and that these lines can be used as an assay for chicken T-cell lymphokines. Furthermore, they provide an interesting model for the study of avian and mammalian T-cell transformation. Implications for the study of Marek's disease are also discussed.

Abstract
In a 48-week open trial, 18 patients with active rheumatoid arthritis (RA), resistant to second line agents, received 200 mg minocycline daily. Twelve patients completed 48 weeks of therapy. Statistically significant improvement was noted in almost all variables of disease activity. Three patients discontinued therapy because of lack of improvement, 2 patients because of side effects and one patient was lost to followup. Cytofluorographic analysis revealed a significant decrease in expression of a T cell activation antigen (gp 26). Our data suggest that minocycline could be a useful therapeutic agent in RA.

Abstract
The CD27 Ag is expressed by the majority of resting T lymphocytes and appears to play a crucial role in T cell activation. We found that some resting peripheral blood NK cells also express CD27. Furthermore, CD27 expression was up-regulated on NK cells stimulated by IL-2. The cytolytic activity of IL-2-activated, but not resting, NK cells was inhibited by an anti-CD27 mAb (anti-1A4). However, anti-1A4 did not affect conjugate formation between IL-2-activated NK cells and tumor cell targets. In contrast, anti-1A4 inhibited CD2-mediated calcium mobilization and the serine esterase activity of NK cell granules. These inhibitory effects could be mediated in part by increase in intracellular cAMP levels induced by anti-1A4. Our results suggest that the CD27 Ag plays an important role in the regulation of activated NK cells.

Abstract
Hereditary tubulointerstitial nephritis is a prominent cause of renal failure in humans. A variety of animal models utilizing immunologically induced nephritis have been developed. The kdkd congenic variant of the CBA/Ca mouse has normal kidneys at birth but develops progressive, lethal autoimmune nephritis beginning at approximately Week 8. The destruction of renal tubular epithelium in mediated by a population of antigen-specific, H-2Kk-restricted, Lyt-2+, L3T4- T cells. The present experiments demonstrate that systemic treatment with anti-ICAM-1 monoclonal antibody reduces kidney disease in kdkd mice. Anti-ICAM-1 mab localizes to inflammatory sites in the kidney and effects a significant reduction in leukocyte infiltration. Concomitantly, urine protein levels of anti-ICAM-1-treated mice are significantly reduced. The use of anti-adhesion molecule monoclonal antibodies that alter leukocyte activity and/or trafficking may be useful therapies for certain autoimmune disorders.

Abstract
Relatively little is known about the transcriptional control of genes expressed late after T cell activation. We have identified four genes expressed 3 to 5 days after T cell activation by alloantigen or mitogen. Here we report the genomic organization of 519, one of these late T cell activation Ag. Analysis of the genomic clone revealed that 519 consists of six exons. Ribonuclease protection experiments indicated that the most abundant transcript arising from this region is an alternatively spliced form of 519, referred to as 520, which lacks exon 2 and is similar in sequence to NKG5, a cDNA identified in NK cells. These experiments also revealed the existence of two other alternatively spliced RNA transcripts, with heterogeneity in exon 2. Primer extension analysis and ribonuclease protection assays demonstrated that there are two prominent start sites for transcription; however, there is no evidence for the NKG5 transcript in T cells, indicating that NKG5 may represent a NK cell-specific form of 520. The 5' flanking region of this gene contains several previously identified sequences involved in transcriptional regulation, as well as some potentially interesting novel conserved motifs.

Abstract
In a recent study we reported that CD27 is expressed on a subpopulation of human B lymphocytes and presented circumstantial phenotypic evidence that CD27 expression may be acquired late during B cell differentiation. Here we present functional data showing that, after in vitro stimulation, CD27+ but not CD27- B cells secrete large amounts of both IgM and IgG. Using double immunofluorescence staining of CD27 and IgD, three functionally different B cell subsets representing distinct stages of B cell differentiation can be isolated: 1) the CD27- IgD+ B cells, which do not secrete appreciable Ig; 2) the CD27+IgD+ B cells, which exclusively secrete IgM; and 3) the CD27+IgD- B cells, which comprise the IgG-producing cells. Furthermore, costimulation of CD27- B cells with low m.w. B cell growth factor, in the presence or in the absence of a CD40 mAb, does not induce these cells to become Ig-secreting cells. Although CD27- B cells hardly secrete Ig of any isotype in response to Staphylococcus aureus+IL-2, these cells proliferate vigorously and express the IL-2R alpha chain (CD25) under these stimulatory conditions. Furthermore, both CD27- and CD27+ B cells are capable of producing similar amounts of IL-6 and TNF-alpha. Taken together, these findings indicate that CD27 is a unique non-Ig surface marker discriminating naive from primed B lymphocytes. Furthermore, the capacity to proliferate and to secrete the B cell differentiation factors IL-6 and TNF-alpha already exists at an early B cell differentiation stage at which the cells lack CD27 expression and are not induced to produce Ig.

Abstract
T cell activation and T cell receptor variable (V) regions were studied with monoclonal antibodies in peripheral blood lymphocytes from 22 patients with measles. Increased (greater than 5%) activated T cells (HLA-DR+ CD3+ cells) were noted in 14 of the 22 patients. Elevations of V beta 5+ and V beta 8+ T cells were observed in two and four patients, respectively, and appeared to be associated with T cell activation. The duration of fever was significantly prolonged in those with increased (greater than 10%) activated T cells (p less than 0.01). These results suggest that T cell activation and the preferential expansion of V beta 8+ and V beta 5+ T cells are associated with the pathogenic process of measles.

Abstract
On the basis of expression of the T cell differentiation antigen CD27, human peripheral blood CD4+ memory cells can be divided into two subsets, a large CD45RA-CD27+ (82%) and a small CD45RA-CD27- (18%) population. Analysis of the functional properties of these memory T cell subsets showed that proliferative responses to the recall antigen tetanus toxoid (TT), shortly after booster immunization, were mainly confined to the CD27- population. Also, in atopic individuals, proliferative responses to allergens for which these individuals are sensitized, were limited to the CD45RA-CD27- population. After stimulation with CD3 monoclonal antibody and phorbol ester, CD27+ cells produced vast amounts of interleukin (IL)-2 but minimal amounts of IL-4, whereas in marked contrast, CD27- T cells secreted low levels of IL-2 and high levels of IL-4. The capacity of the vast majority of these latter cells to produce IL-4 was found to be a stable feature since high IL-4 secreting T cell clones were generated from the CD27- subset. These findings suggest that upon renewed as well as chronic antigenic stimulation in vivo, memory T cells acquire the CD45RA-CD27- phenotype and that, as a consequence, in this subset functionally differentiated CD4+ T cells are compartmentalized. Our results predict that analysis of the small CD27- subset of memory cells, that makes up approximately 10% of the peripheral blood T cell population, will provide information on the specificity and function of responding CD4+ T cells at a given point in time in healthy and diseased individuals.

Abstract
We have identified and cloned cDNA for a novel cell-surface protein that we have named Tactile for T cell activation, increased late expression. It is expressed on normal T cell lines and clones, and some transformed T cells, but no other cultured cell lines tested. It is expressed at low levels on peripheral T cells and is strongly up-regulated after activation, peaking 6 to 9 days after the activating stimulus. It is also up-regulated on NK cells activated in allogeneic cultures. It is not found on peripheral B cells but is expressed at very low levels on activated B cells. Tactile-specific mAb immunoprecipitates a band of 160 kDa when reduced and bands of 240, 180, and 160 kDa nonreduced. Using an antiserum produced with affinity-purified Tactile protein to screen a lambda gt11 library, we have identified Tactile cDNA. Northern blot analysis shows an expression pattern similar to that of the protein and transfection of COS cells with the full-length 5.2-kb cDNA results in cell-surface expression. Comparison with the sequence databanks show that Tactile is a member of the immunoglobulin gene superfamily, with similarity to Drosophila amalgam, the melanoma Ag MUC-18, members of the carcinoembryonic Ag family, the poliovirus receptor, and the neural cell adhesion molecule. The deduced primary sequence encodes a protein with three Ig domains, a long serine/threonine/proline-rich region typical of an extensively O-glycosylated domain, a transmembrane domain, and a 45 residue cytoplasmic domain. These data suggest that Tactile may be involved in adhesive interactions of activated T and NK cells during the late phase of the immune response.
