Abstract
Cellular components of the tumor microenvironment, including myeloid cells, play important roles in the progression of lung adenocarcinoma (LUAD) and its response to therapy. Here, we characterize the function of the ubiquitin ligases Siah1a/2 in regulating the differentiation and activity of alveolar macrophages (AM) and assess the implication of Siah1a/2 control of AMs for carcinogen-induced LUAD. Macrophage-specific genetic ablation of Siah1a/2 promoted accumulation of AMs with an immature phenotype and increased expression of protumorigenic and pro-inflammatory Stat3 and β-catenin gene signatures. Administration of urethane to wild-type mice promoted enrichment of immature-like AMs and lung tumor development, which was enhanced by macrophage-specific Siah1a/2 ablation. The profibrotic gene signature seen in Siah1a/2-ablated immature-like macrophages was associated with increased tumor infiltration of CD14+ myeloid cells and poorer survival of patients with LUAD. Single-cell RNA-seq confirmed the presence of a cluster of immature-like AMs expressing a profibrotic signature in lungs of patients with LUAD, a signature enhanced in smokers. These findings identify Siah1a/2 in AMs as gatekeepers of lung cancer development. SIGNIFICANCE The ubiquitin ligases Siah1a/2 control proinflammatory signaling, differentiation, and profibrotic phenotypes of alveolar macrophages to suppress lung carcinogenesis.

Abstract
PSGL-1 (P-selectin glycoprotein-1) is a T cell-intrinsic checkpoint regulator of exhaustion with an unknown mechanism of action. Here, we show that PSGL-1 acts upstream of PD-1 and requires co-ligation with the T cell receptor (TCR) to attenuate activation of mouse and human CD8+ T cells and drive terminal T cell exhaustion. PSGL-1 directly restrains TCR signaling via Zap70 and maintains expression of the Zap70 inhibitor Sts-1. PSGL-1 deficiency empowers CD8+ T cells to respond to low-affinity TCR ligands and inhibit growth of PD-1-blockade-resistant melanoma by enabling tumor-infiltrating T cells to sustain an elevated metabolic gene signature supportive of increased glycolysis and glucose uptake to promote effector function. This outcome is coupled to an increased abundance of CD8+ T cell stem cell-like progenitors that maintain effector functions. Additionally, pharmacologic blockade of PSGL-1 curtails T cell exhaustion, indicating that PSGL-1 represents an immunotherapeutic target for PD-1-blockade-resistant tumors.

Abstract
Immune suppressive factors of the tumor microenvironment (TME) undermine viability and exhaust the activities of the intratumoral cytotoxic CD8 + T lymphocytes (CTL) thereby evading anti-tumor immunity and decreasing the benefits of immune therapies. To counteract this suppression and improve the efficacy of therapeutic regimens, it is important to identify and understand the critical regulators within CD8 + T cells that respond to TME stress and tumor-derived factors. Here we investigated the regulation and importance of activating transcription factor-4 (ATF4) in CTL using a novel Atf4ΔCD8 mouse model lacking ATF4 specifically in CD8 + cells. Induction of ATF4 in CD8 + T cells occurred in response to antigenic stimulation and was further increased by exposure to tumor-derived factors and TME conditions. Under these conditions, ATF4 played a critical role in the maintenance of survival and activities of CD8 + T cells. Conversely, selective ablation of ATF4 in CD8 + T cells in mice rendered these Atf4ΔCD8 hosts prone to accelerated growth of implanted tumors. Intratumoral ATF4-deficient CD8 + T cells were under-represented compared to wild-type counterparts and exhibited impaired activation and increased apoptosis. These findings identify ATF4 as an important regulator of viability and activity of CD8 + T cells in the TME and argue for caution in using agents that could undermine these functions of ATF4 for anti-cancer therapies.

Abstract
BACKGROUND Different factors may lead to hepatitis. Among which are liver inflammation and poisoning. We chose two hepatitis models, typical for these two underlying causes. Thus, we aimed to characterize the role of protease-activated receptor 2 (Par2) in liver regeneration and inflammation to reconcile Par2 conflicting role in many damage models, which sometimes aggravates the induced damage and sometimes alleviates it. METHODS WT and knockout (Par2KO) mice were injected with concanavalin A (ConA) to induce immune-mediated hepatitis or with carbon tetrachloride (CCl4) to elicit direct hepatic damage. To distinguish the immune component from the liver regenerative response, we conducted bone marrow (BM) replacements of WT and Par2KO mice and repeated the damage models. RESULTS ConA injection caused limited damage in Par2KO mice livers, while in the WT mice severe damage followed by leukocyte infiltration was evident. Reciprocal BM replacement of WT and Par2KO showed that WT BM-reconstituted Par2KO mice displayed marked liver damage, while in Par2KO BM-reconstituted WT mice, the tissue was generally protected. In the CCl4 direct damage model, hepatocytes regenerated in WT mice, whereas Par2KO mice failed to recover. Reciprocal BM replacement did not show significant differences in hepatic regeneration. In Par2KO mice, hepatitis was more apparent, while WT recovered regardless of the BM origin. CONCLUSIONS We conclude that Par2 activation in the immune system aggravates hepatitis and that Par2 activation in the damaged tissue promotes liver regeneration. When we incorporate this finding and revisit the literature reports, we reconciled the conflicts surrounding Par2's role in injury, recovery, and inflammation.

Abstract
There is an unmet need for more effective treatment strategies for diffuse intrinsic pontine glioma (DIPG), a devastating brain tumour arising in children and young adults. While immunotherapy is emerging as a powerful approach to treatment of other cancers, clinical trials with immune checkpoint inhibitors have failed to show a survival benefit for DIPG patients. In this study, we analysed the expression of immune checkpoint molecules on the surface of human and murine DIPG cells by flow cytometry and identified CD155 and B7-H3 as the most highly expressed checkpoint molecules, with minimal expression of PD-L1, PD-L2, Galectin-9, CEACAM-1, CD86, CD252 and CD137. These findings were confirmed in primary patient samples from pediatric brain tumours, including high-grade gliomas, medulloblastomas and ependymomas. To test whether CD155 inhibition increases susceptibility to CD8+ T cell killing in vitro, we cultured DIPG cells expressing ovalbumin (OVA) with CD8+ T cells from OT-I mice, which express T cell receptors specific for OVA. Addition of CD155 blocking antibodies to these cultures increased expression of T cell activation markers (CD25, CD44 and CD69) as well as T cell-mediated tumour killing, supporting the notion that CD155 can function as an immune checkpoint in DIPG. In addition to its effects on T cells, CD155 also exerted direct effects on tumour cells: treatment with anti-CD155 antibodies led to impaired cell viability, and shRNA-mediated knockdown of CD155 resulted in reduced cell proliferation in vitro. Strikingly, knockdown of CD155 also led to reduced growth of DIPG cells in vivo, and mice transplanted with the CD155-deficient cells had a clear survival benefit compared to mice transplanted with wild type cells. These studies demonstrate that CD155 functions as an immune checkpoint and as a regulator of tumor growth in DIPG, and suggest that targeting CD155 could be a valuable therapeutic strategy for this devastating disease.

Abstract
MicroRNAs (miRNAs/miRs) are small, endogenous noncoding RNAs that are important post-transcriptional regulators with clear roles in the development of the immune system and immune responses. Using miRNA microarray profiling, we characterized the expression profile of naive and in vivo generated murine effector antiviral CD8+ T cells. We observed that out of 362 measurable mature miRNAs, 120 were differentially expressed by at least 2-fold in influenza-specific effector CD8+ CTLs compared with naive CD8+ T cells. One miRNA found to be highly downregulated on both strands in effector CTLs was miR-139. Because previous studies have indicated a role for miR-139-mediated regulation of CTL effector responses, we hypothesized that deletion of miR-139 would enhance antiviral CTL responses during influenza virus infection. We generated miR-139-/- mice or overexpressed miR-139 in T cells to assess the functional contribution of miR-139 expression in CD8+ T cell responses. Our study demonstrates that the development of naive T cells and generation or differentiation of effector or memory CD8+ T cell responses to influenza virus infection are not impacted by miR-139 deficiency or overexpression; yet, miR-139-/- CD8+ T cells are outcompeted by wild-type CD8+ T cells in a competition setting and demonstrate reduced responses to Listeria monocytogenes Using an in vitro model of T cell exhaustion, we confirmed that miR-139 expression similarly does not impact the development of T cell exhaustion. We conclude that despite significant downregulation of miR-139 following in vivo and in vitro activation, miR-139 expression is dispensable for influenza-specific CTL responses.

Abstract
Effective T cell differentiation during acute virus infections leads to the generation of effector T cells that mediate viral clearance, as well as memory T cells that confer protection against subsequent reinfection. While inhibitory immune checkpoints have been shown to promote T cell dysfunction during chronic virus infections and in tumors, their roles in fine tuning the differentiation and responses of effector and memory T cells are only just beginning to be appreciated. We previously identified PSGL-1 as a fundamental regulator of T cell exhaustion that sustains expression of several inhibitory receptors, including PD-1. We now show that PSGL-1 can restrict the magnitude of effector T cell responses and memory T cell development to acute LCMV virus infection by limiting survival, sustaining PD-1 expression, and reducing effector responses. After infection, PSGL-1-deficient effector T cells accumulated to a greater extent than wild type T cells, and preferentially generated memory precursor cells that displayed enhanced accumulation and functional capacity in response to TCR stimulation as persisting memory cells. Although, PSGL-1-deficient memory cells did not exhibit inherent greater sensitivity to cell death, they failed to respond to a homologous virus challenge after adoptive transfer into naïve hosts indicating an impaired capacity to generate memory effector T cell responses in the context of viral infection. These studies underscore the function of PSGL-1 as a key negative regulator of effector and memory T cell differentiation and suggest that PSGL-1 may limit excessive stimulation of memory T cells during acute viral infection.

Abstract
Abstract
Functional T cell exhaustion develops with persistent antigen exposure during chronic viral infection and cancer. Greater insights into T cell exhaustion are needed to promote immunity to viruses and tumors. RNF5 (RING-finger protein 5) is an E3 ubiquitin ligase that functions in protein degradation. We previously found enhanced anti-tumor responses in RNF5−/− mice, which was coupled with greater recovery and function of CD8+ T cell in melanoma tumors. Tumor-infiltrating RNF5−/− CD8+ T cells expressed high levels of inhibitory receptors (IR), yet greater functionality compared to WT CD8+ T cells, suggesting greater activation. To further assess RNF5-dependent regulation of CD8+ T cell exhaustion, we used the chronic LCMV Cl13 infection that has defined states of progressive T cell exhaustion. Virus-specific CD8+ T cells were significantly increased in RNF5−/− mice leading to greater numbers of cytokine producers, which expressed high levels of IRs. They also expressed higher levels of TOX, a transcriptional regulator of T cell exhaustion and persistence. With low dose infection, RNF5−/− mice displayed decreased morbidity and CD8+ T cells acquired a highly functional memory phenotype rather than exhaustion. To identify T cell intrinsic role(s) of RNF5, we analyzed anti-viral responses in bone marrow chimeras lacking RNF5 only in T cells and used an in vitro T cell exhaustion assay. RNF5−/− CD8+ T cells also expressed high levels of IRs and TOX, as did the in vitro exhausted T cells yet importantly displayed enhanced cytokine production compared to WT cells. These data reveal a T cell-intrinsic role of RNF5 in promoting exhaustion in settings of chronic antigen stimulation.

Abstract
Growing evidence supports the importance of gut microbiota in the control of tumor growth and response to therapy. Here, we select prebiotics that can enrich bacterial taxa that promote anti-tumor immunity. Addition of the prebiotics inulin or mucin to the diet of C57BL/6 mice induces anti-tumor immune responses and inhibition of BRAF mutant melanoma growth in a subcutaneously implanted syngeneic mouse model. Mucin fails to inhibit tumor growth in germ-free mice, indicating that the gut microbiota is required for the activation of the anti-tumor immune response. Inulin and mucin drive distinct changes in the microbiota, as inulin, but not mucin, limits tumor growth in syngeneic mouse models of colon cancer and NRAS mutant melanoma and enhances the efficacy of a MEK inhibitor against melanoma while delaying the emergence of drug resistance. We highlight the importance of gut microbiota in anti-tumor immunity and the potential therapeutic role for prebiotics in this process.

Abstract
Abstract
We previously identified that the adhesion molecule P-selectin glycoprotein ligand-1 (PSGL-1) regulates T cell function and exhaustion in responses to chronic viral infection and melanoma tumors. Subsequently, our studies have focused on investigating the mechanisms by which PSGL-1 regulates T cell activation and exhaustion and evaluating PSGL-1 as a target for cancer immunotherapy. Using the CD4cre system in combination with PSGL-1-floxed mice, we find that T cell intrinsic deletion of PSGL-1 is sufficient to promote enhanced tumor growth control of mesothelioma as well as melanoma tumors. We have found that in vivo PSGL-1 blockade recapitulates the enhanced melanoma tumor growth control observed with PSGL-1-/- CD8+ T cells and limits the development of T cell exhaustion during chronic LCMV Clone 13 viral infection. Conversely, ligation of PSGL-1 in vitro or in vivo drives enhanced upregulation T cell exhaustion markers, most notably PD-1 expression. Phosphoproteomic analysis of early T cell activation revealed the rapid upregulation of more than 30 phosphorylated proteins with significantly enhanced expression following PSGL-1 ligation during T cell activation than T cell activation alone. GSEA and western blot analysis confirmed the increased expression of several regulators of T cell signaling including pAkt1 and pErk in both activated PSGL-1-/- T cells and following PSGL-1 ligation during T cell activation. Single-cell RNA-sequencing of melanoma tumor-specific PSGL-1-/- CD8+ T cells identified differential modulation of genes associated with T cell metabolism and effector responses, including increased Mtor and Hif1a in tumors and Tcf7 in tumor-draining lymph nodes. The Seahorse glycolysis stress test identified that PSGL-1-/- T cells show increased glycolysis after 72 hours of in vitro activation at both sub-optimal and optimal levels of αCD3 stimulation, and 2-NBDG glucose uptake assays confirmed increased glucose uptake by PSGL-1-/- CD8+ T cells within two hours of stimulation. Further, 2-NBDG uptake was increased by PSGL-1-/- CD8+ T cells ex vivo from melanoma tumors. Importantly, this increased glycolytic phenotype does not come at the cost of CD8+ T cell stemness, as determined by TCF-1 staining. We hypothesize that PSGL-1 serves as a key regulator of early T cell activation and repeated signaling through PSGL-1 promotes differentiation into exhausted CD8+ T cells by sustaining TCR signaling. Conversely, we hypothesize that the absence of PSGL-1 allows for faster initiation and termination of TCR signaling, inhibiting differentiation into exhausted CD8+ T cells. Taken together, these data show that PSGL-1 signaling has an intrinsic and immediate role in the development of T cell responses and their metabolic profile which may drive their enhanced responses to tumors.

Abstract
Abstract
Many immunotherapies act by enhancing T-cell killing of tumor cells. Cytotoxic T cells recognize antigens presented by class I major histocompatibility complex (MHC-I) proteins on tumor cells. Our studies suggest that medulloblastomas and high-grade gliomas lacking the p53 tumor suppressor do not express surface MHC-I and are therefore resistant to immune rejection. Mechanistically, this is because p53 regulates expression of the peptide transporter Tap1 and the aminopeptidase Erap1, which are required for MHC-I trafficking to the cell surface. Treatment with tumor necrosis factor or lymphotoxin beta receptor agonist rescues expression of Erap1, Tap1, and MHC-I on p53 mutant tumor cells. In vivo, TNF treatment prolongs survival and markedly augments the efficacy of the immune checkpoint inhibitor anti-PD-1. These studies identify p53 as a key regulator of immune evasion in vivo and suggest that TNF could be used to enhance sensitivity of p53-mutant tumors to immunotherapy.

Abstract
Abstract
We previously identified PSGL-1 (P-selectin glycoprotein-1) as a T cell-intrinsic, cell surface checkpoint inhibitor during chronic viral infection. In this model, we found that cross-linking PSGL-1 with antibody reduced signaling through the T cell receptor (TCR) in exhausted T cells and further upregulated PD-1 expression. However, the mechanism responsible for PD-1 regulation by PSGL-1 remained to be described. Here we show that, in naïve T cells, PSGL-1 ligation results in enhanced PD-1 expression following activation through the T cell receptor. Furthermore, naïve T cells lacking PSGL-1 fail to upregulate PD-1 to the same extent as wild type T cells following activation. Strikingly we have discovered that T cells lacking PSGL-1 showed reduced calcium signaling. In T cells, the calcium/calcineurin/NFAT pathway is important for induction of many genes including PD-1. Consequently, PSGL-1 deficient T cells also exhibit reduced nuclear translocation of NFAT explaining the reduced PD-1 expression. Conversely, we found that ligating PSGL-1 enhanced NFAT nuclear translocation with TCR signaling thus contributing to upregulation of PD-1. Therefore, by regulating calcium signaling through the T cell receptor, PSGL-1 modulates the extent of PD-1 expression early in activation and subsequently influencing the extent of T cell exhaustion. Further studies aim to elucidate how PSGL-1 regulates calcium signaling through the T cell receptor.

Abstract
Abstract
We previously identified that the adhesion molecule P-selectin glycoprotein ligand-1 (PSGL-1) regulates T cell function and exhaustion in response to chronic viral infection and tumors. Subsequent studies have focused on investigating the role of PSGL-1 signaling in T cell responses, with an emphasis on understanding the mechanisms by which PSGL-1 regulates T cell exhaustion. Single-cell RNA-sequencing of tumor infiltrating PSGL-1−/− CD8+ T cells identified the upregulation and differential modulation of several genes associated with T cell metabolism and enhanced intratumoral responses, including Mtor, Hif1a, and Mki67 in Gzmb/Ifng double-positive cells from tumors and Tcf7 in both tumor draining and non-draining inguinal lymph nodes. These data suggest an important role for PSGL-1 signaling in the development and maintenance of effective anti-tumor T cell responses to melanoma. Using the Seahorse glycolysis stress test, we identified that both CD4+ and CD8+ PSGL-1−/− T cells demonstrate increased glycolysis after 72 hours of in vitro activation compared to wild-type T cells. In situ activation of PSGL-1−/− CD8+ T cells demonstrated that PSGL-1−/− CD8+ T cells have increased glycolysis and increased glycolytic capacity at both sub-optimal and optimal levels of α-CD3 stimulation, and 2-NBDG glucose uptake assays confirmed increased glucose uptake by PSGL-1−/− CD8+ T cells within two hours of stimulation. Importantly, this increased glycolytic phenotype does not come at the cost of CD8+ T cell stemness, as determined by TCF-1 staining. Taken together, these data show that PSGL-1 signaling has an intrinsic and immediate role in the development of T cell responses and their metabolic profile in response to melanoma tumors.

Abstract
Abstract
Endoplasmic reticulum (ER) stress is induced by the accumulation of misfolded proteins and other cellular stresses, which lead to the unfolded protein response to restore ER homeostasis. Previous studies have shown that the ER stress response is required for T cell activation and differentiation. However, recent studies demonstrated that inhibition or deletion of ER stress mediators in T cells actually promotes anti-tumor immunity. Therefore, this incongruity as to the role of ER stress response in effector T cell function warrants further investigation. Our lab previously identified that the adhesion molecule, P-selectin glycoprotein ligand-1 (PSGL-1), acts as a T cell immune checkpoint regulator. PSGL-1-deficiency enhances T cell function, resulting in the clearance of chronic viral infection and dramatic tumor control. To better understand the contribution of ER stress to T cell function, we assessed T cell phenotype and function together with the ER stress mediators, XBP1s and ATF4, in highly-functional PSGL-1−/− T cells as well as exhausted wild-type T cells in both tumor and virus models. In melanoma models, ER stress was highly induced in activated tumor-infiltrating T cells (TILs). Effector CD8+ TILs producing IFNg displayed elevated XBP1s and ATF4 compared to IFNg− TILs. Upon chronic LCMV Cl13 viral infection in PSGL-1−/− mice, we found increased virus-specific T cells with enhanced multi-functional effector responses and increased memory/stem cell-like T cell populations characterized by the expression of the transcription factor TCF-1, as well as increased ER stress responses. Together, these data suggest that ER stress plays an essential role in effector T cell functions in settings of chronic antigen stimulation.

Abstract
The immune system, and in particular, cytotoxic CD8+ T cells (CTLs), plays a vital part in the prevention and elimination of tumors. In many patients, however, CTL-mediated tumor killing ultimately fails in the clearance of cancer cells resulting in disease progression, in large part due to the progression of effector CTL into exhausted CTL. While there have been major breakthroughs in the development of CTL-mediated “reinvigoration”-driven immunotherapies such as checkpoint blockade therapy, there remains a need to better understand the drivers behind the development of T cell exhaustion. Our study highlights the unique differences in T cell exhaustion development in tumor-specific CTL which arises over time in a mouse model of mesothelioma. Importantly, we also show that peripheral tumor-specific T cells have a unique expression profile compared to exhausted tumor-infiltrating CTL at a late-stage of tumor progression in mice. Together, these data suggest that greater emphasis should be placed on understanding contributions of individual microenvironments in the development of T cell exhaustion.

Abstract
Understanding the mechanisms underlying anti-tumor immunity is pivotal for improving immune-based cancer therapies. Here, we report that growth of BRAF-mutant melanoma cells is inhibited, up to complete rejection, in Siah2-/- mice. Growth-inhibited tumors exhibit increased numbers of intra-tumoral activated T cells and decreased expression of Ccl17, Ccl22, and Foxp3. Marked reduction in Treg proliferation and tumor infiltration coincide with G1 arrest in tumor infiltrated Siah2-/- Tregs in vivo or following T cell stimulation in culture, attributed to elevated expression of the cyclin-dependent kinase inhibitor p27, a Siah2 substrate. Growth of anti-PD-1 therapy resistant melanoma is effectively inhibited in Siah2-/- mice subjected to PD-1 blockade, indicating synergy between PD-1 blockade and Siah2 loss. Low SIAH2 and FOXP3 expression is identified in immune responsive human melanoma tumors. Overall, Siah2 regulation of Treg recruitment and cell cycle progression effectively controls melanoma development and Siah2 loss in the host sensitizes melanoma to anti-PD-1 therapy.

Abstract
Inflammatory bowel disease (IBD) is prevalent, but the mechanisms underlying disease development remain elusive. We identify a role for the E3 ubiquitin ligase RNF5 in IBD. Intestinal epithelial cells (IECs) express a high level of RNF5, while the colon of Rnf5−/− mice exhibits activated dendritic cells and intrinsic inflammation. Rnf5−/− mice exhibit severe acute colitis following dextran sodium sulfate (DSS) treatment. S100A8 is identified as an RNF5 substrate, resulting in S100A8 ubiquitination and proteasomal-dependent degradation that is attenuated upon inflammatory stimuli. Loss of RNF5 from IECs leads to enhanced S100A8 secretion, which induces mucosal CD4+ T cells, resulting in Th1 pro-inflammatory responses. Administration of S100A8-neutralizing antibodies to DSS-treated Rnf5−/− mice attenuates acute colitis development and increases survival. An inverse correlation between RNF5 and S100A8 protein expression in IECs of IBD patients coincides with disease severity. Collectively, RNF5-mediated regulation of S100A8 stability in IECs is required for the maintenance of intestinal homeostasis. Fujita et al. show that RNF5 regulation of S100A8 stability in intestinal epithelial cells defines the degree of pro-inflammatory response, culminating in severe intestinal inflammation following DSS treatment to Rnf5−/− mice. Neutralizing S100A8 antibodies attenuates acute colitis phenotypes, and inverse RNF5/S100A8 expression coincides with clinical severity in IBD patients.

Abstract
Numerous independent studies link gut microbiota composition and disease and imply a causal role of select commensal microbes in disease etiology. In the gut, commensal microbiota or pathobionts secrete metabolites that underlie pathological conditions, often impacting proximal tissues and gaining access to the bloodstream. Here we focus on extrinsic and intrinsic factors affecting composition of gut microbiota and their impact on the immune system, as key drivers of anti-tumor immunity. In discussing exciting advances relevant to microbiome-tumor interaction, we note existing knowledge gaps that need to be filled to advance basic and clinical research initiatives.

Abstract
Effective adaptive immune responses are characterized by stages of development and maturation of T and B cell populations that respond to disturbances in the host homeostasis in cases of both infections and cancer. For the T cell compartment, this begins with recognition of specific peptides by naïve, antigen-inexperienced T cells that results in their activation, proliferation, and differentiation, which generates an effector population that clears the antigen. Loss of stimulation eventually returns the host to a homeostatic state, with a heterogeneous memory T cell population that persists in the absence of antigen and is primed for rapid responses to a repeat antigen exposure. However, in chronic infections and cancers, continued antigen persistence impedes a successful adaptive immune response and the formation of a stereotypical memory population of T cells is compromised. With repeated antigen stimulation, responding T cells proceed down an altered path of differentiation that allows for antigen persistence, but much less is known regarding the heterogeneity of these cells and the extent to which they can become “memory-like,” with a capacity for self-renewal and recall responses that are characteristic of bona fide memory cells. This review focuses on the differentiation of CD4+ and CD8+ T cells in the context of chronic antigen stimulation, highlighting the central observations in both human and mouse studies regarding the differentiation of memory or “memory-like” T cells. The importance of both the cellular and molecular drivers of memory T cell development are emphasized to better understand the consequences of persisting antigen on T cell fates. Integrating what is known and is common across model systems and patients can instruct future studies aimed at further understanding T cell differentiation and development, with the goal of developing novel methods to direct T cells toward the generation of effective memory populations.

Abstract
Abstract
Many immunotherapies act by enhancing T cell killing of tumor cells. CD8+ cytotoxic T cells recognize antigens presented by class I major histocompatibility complex (MHC-I) proteins on tumor cells. Here we show that medulloblastomas lacking the p53 tumor suppressor do not express surface MHC-I and are therefore resistant to immune rejection. Mechanistically, this is because p53 regulates expression of the peptide transporter Tap1 and the aminopeptidase Erap1, which are required for MHC-I trafficking to the cell surface. Treatment with tumor necrosis factor (TNF) or lymphotoxin beta receptor agonist (LTβRag) rescues expression of Erap1, Tap1 and MHC-I on p53-mutant tumor cells. In vivo, TNF treatment prolongs survival and markedly augments the efficacy of the immune checkpoint inhibitor anti-PD-1. These studies identify p53 as a key regulator of immune evasion in vivo, and suggest that TNF could be used to enhance sensitivity of p53-mutant tumors to immunotherapy.

Abstract
Abstract
Effective T cell responses depend on adhesion mechanisms that guide T cells to sites of infection and inflammation. P-selectin glycoprotein ligand-1 (PSGL-1) has been shown to impact T cell migration; however, its role in the differentiation of responding T cells has not been investigated. Since PSGL-1 is highly expressed on naïve, effector, and memory T cells with varying degrees of glycosylation that impact ligand binding, we hypothesized that PSGL-1 may regulate T cell fates. Using mice deficient in PSGL-1 and we found that PSGL-1 limited the magnitude of the ensuing T cell response. PSGL-1-deficient mice had an increased accumulation of anti-viral CD4+ and CD8+ T cells after acute LCMV infection. Virus-specific PSGL-1-deficient T cells had enhanced survival and were not hyper proliferative. Furthermore, PSGL-1-deficient T cells had superior effector function, downregulation of PD-1 and other inhibitory receptors and changes in their transcriptional signature. After viral clearance, more CD4+ and CD8+ PSGL-1-deficient T cells survived to form memory cells. Interestingly, memory T cells from PSGL-1-deficient mice sustained PD-1 downregulation implying that PSGL-1 may regulate inhibitory receptors in memory T cells. Our findings highlight a previously unrecognized role for PSGL-1 in negatively regulating T cell differentiation during acute viral infection.

Abstract
Nuclear pore complexes (NPCs) are channels connecting the nucleus with the cytoplasm. We report that loss of the tissue-specific NPC component Nup210 causes a severe deficit of naïve CD4+ T cells. Nup210-deficient CD4+ T lymphocytes develop normally but fail to survive in the periphery. The decreased survival results from both an impaired ability to transmit tonic T cell receptor (TCR) signals and increased levels of Fas, which sensitize Nup210-/- naïve CD4+ T cells to Fas-mediated cell death. Mechanistically, Nup210 regulates these processes by modulating the expression of Cav2 (encoding Caveolin-2) and Jun at the nuclear periphery. Whereas the TCR-dependent and CD4+ T cell-specific upregulation of Cav2 is critical for proximal TCR signaling, cJun expression is required for STAT3-dependent repression of Fas. Our results uncover an unexpected role for Nup210 as a cell-intrinsic regulator of TCR signaling and T cell homeostasis and expose NPCs as key players in the adaptive immune system.

Abstract
Mouse models of cancer remain the preferred means to assess the efficacy of anti-cancer therapies, and several models have been used to address the effect of cancer drugs or in the discovery of biomarkers. The Yale University Mutant melanoma lines, YUMM1.5 and YUMMER1.7 murine tumor models were developed from the BrafV600E/Pten/−/−Cdkn2a−/− engineered mouse model to more closely reflect poorly immunogenic and highly mutated melanomas, respectively, that are driven by human disease-relevant mutations; however, the dominant T cell-recognized epitopes specific for these tumors remains unknown. We therefore sought to engineer OVA-expressing versions of the YUMM1.5 and YUMMER1.7 tumor lines, hereafter referred to as YUMM1.5-OVA and YUMMER1.7-OVA. Using stable transfection to insert a plasmid expressing full-length secretory ovalbumin, we have generated polyclonal and monoclonal cell lines that generate an in vivo OVA-specific response as validated by MHC class I tetramer staining and cytokine production following OVA peptide stimulation. Together, these two new models for melanoma tumors will allow us to assess intrinsic and extrinsic mechanisms regulating the generation of effective and recovery of exhausted T cell responses to melanoma in vivo.

Abstract
T cells mediating influenza viral control are instructed in lymphoid and nonlymphoid tissues to differentiate into memory T cells that confer protective immunity. The mechanisms by which influenza virus-specific memory CD4+ T cells arise have been attributed to changes in transcription factors, cytokines and cytokine receptors, and metabolic programming. The molecules involved in these biosynthetic pathways, including proteins and lipids, are modified to varying degrees of glycosylation, fucosylation, sialation, and sulfation, which can alter their function. It is currently unknown how the glycome enzymatic machinery regulates CD4+ T cell effector and memory differentiation. In a murine model of influenza virus infection, we found that fucosyltransferase enzymatic activity was induced in effector and memory CD4+ T cells. Using CD4+ T cells deficient in the Fut4/7 enzymes that are expressed only in hematopoietic cells, we found decreased frequencies of effector cells with reduced expression of T-bet and NKG2A/C/E in the lungs during primary infection. Furthermore, Fut4/7-/- effector CD4+ T cells had reduced survival with no difference in proliferation or capacity for effector function. Although Fut4/7-/- CD4+ T cells seeded the memory pool after primary infection, they failed to form tissue-resident cells, were dysfunctional, and were unable to re-expand after secondary infection. Our findings highlight an important regulatory axis mediated by cell-intrinsic fucosyltransferase activity in CD4+ T cell effectors that ensure the development of functional memory CD4+ T cells.

Abstract
Chronic viruses and cancers thwart immune responses in humans by inducing T cell dysfunction. Using a murine chronic virus that models human infections, we investigated the function of the adhesion molecule, P-selectin glycoprotein ligand-1 (PSGL-1), that is upregulated on responding T cells. PSGL-1-deficient mice cleared the virus due to increased intrinsic survival of multifunctional effector T cells that had downregulated PD-1 as well as other inhibitory receptors. Notably, this response resulted in CD4(+)-T-cell-dependent immunopathology. Mechanistically, PSGL-1 ligation on exhausted CD8(+) T cells inhibited T cell receptor (TCR) and interleukin-2 (IL-2) signaling and upregulated PD-1, leading to diminished survival with TCR stimulation. In models of melanoma cancer in which T cell dysfunction occurs, PSGL-1 deficiency led to PD-1 downregulation, improved T cell responses, and tumor control. Thus, PSGL-1 plays a fundamental role in balancing viral control and immunopathology and also functions to regulate T cell responses in the tumor microenvironment.

Abstract
Abstract
Effective T cell responses depend on adhesion mechanisms that guide T cells to sites of infection and inflammation. P-selectin glycoprotein ligand-1 (PSGL-1) has been shown to impact T cell migration; however, its role in the differentiation of responding T cells has not been investigated. Since PSGL-1 is highly expressed on naïve, effector, and memory T cells with varying degrees of glycosylation that impact ligand binding, we hypothesized that PSGL-1 may regulate T cell fates. Using mice deficient in PSGL-1 and three murine models we found that PSGL-1 limits the magnitude of the ensuing T cell response. PSGL-1-deficient mice had an increased accumulation of anti-viral CD4+ and CD8+ T cells after both acute and chronic LCMV infection. Virus-specific PSGL-1-deficient T cells had enhanced survival and were not hyper proliferative. Furthermore, PSGL-1-deficient T cells had superior effector function, downregulation of PD-1 and other inhibitory receptors, and enhanced viral control. The enhanced T cell response resulted in significant mortality of PSGL-1-deficient mice infected with chronic LCMV, whereas all PSGL-1-deficient mice survived the acute LCMV infection. After viral clearance, more CD4+ and CD8+ PSGL-1-deficient T cells survived to form memory cells. Interestingly, resting memory T cells from PSGL-1-deficient mice sustained PD-1 downregulation implying that PSGL-1 may regulate inhibitory receptors in memory T cells. We found that PSGL-1-deficient T cells had superior function in a tumor model and were more effective in controlling melanoma tumors. Our findings in three separate models show a previously unrecognized role for PSGL-1 in negatively regulating T cell responses and may have high therapeutic potential.

Abstract
Abstract
The tumor microenvironment can promote tumor growth by suppressing effector T cell responses. Using a melanoma model that recapitulates aspects of human disease, we investigated the role of the adhesion molecule, P-selectin glycoprotein ligand-1 (PSGL-1) in tumor infiltrating lymphocytes (TILs). We found that PSGL-1 was highly expressed on TILs that also expressed high PD-1 and TIM-3 inhibitory receptors. PSGL-1-deficiency did not impact T cell recruitment in tumors but instead resulted in a greater TIL accumulation. Furthermore, PSGL-1-deficient T cells had reduced PD-1 expression and increased production of effector cytokines that resulted in delayed tumor growth. We did not find differences in Treg recruitment but instead had an increased effector to Treg ratio in tumors. Our findings show that PSGL-1 does not have a nonredundant role in the trafficking of TILs into melanoma tumors, but can act as an immune checkpoint inhibitor to limit anti-tumor T cell responses in the tumor microenvironment thereby promoting tumor growth.

Abstract
Curing type 1 diabetes (T1D) will require lasting control of the autoimmune response that destroys insulin-producing islet β-cells. Re-establishing tolerance by restoring/replacing Tregs has significant potential for treatment of T1D but will require strategies to augment and maintain their efficacy. We previously showed that polyclonal in vitro-induced Tregs can reverse recent onset of T1D in ∼ 50% of NOD mice. Here we report that treatment of newly hyperglycemic animals with a short course of anti-CD44 at the time of Treg transfer improved diabetes reversal to >90%. Anti-CD44 treatment alone delayed diabetes onset and increased the frequencies of pancreatic CD4(+) T cells producing IL-2 or TGF-β, cytokines that support Treg function and survival, without altering production of IFN-γ. These anti-CD44 effects on endogenous T cells were also observed in the context of polyclonal Treg transfer, and the combination treatment also reduced pancreatic infiltrates. The results provide compelling evidence that approaches to modulate the pancreatic milieu to support Treg function and counteract inflammation in the pancreas can greatly enhance the efficacy of adoptively transferred Tregs, and suggest that approaches achieving these outcomes hold promise for long-term control of autoimmunity in T1D.

Abstract
Type I diabetes (T1D) is an autoimmune disease in which an immune response to pancreatic β-cells results in their loss over time. Although the conventional view is that this loss is due to autoimmune destruction, we present evidence of an additional phenomenon in which autoimmunity promotes islet endocrine cell transdifferentiation. The end result is a large excess of δ-cells, resulting from α- to β- to δ-cell transdifferentiation. Intermediates in the process of transdifferentiation were present in murine and human T1D. Here, we report that the peptide caerulein was sufficient in the context of severe β-cell deficiency to induce efficient induction of α- to β- to δ-cell transdifferentiation in a manner very similar to what occurred in T1D. This was demonstrated by genetic lineage tracing and time course analysis. Islet transdifferentiation proceeded in an islet autonomous manner, indicating the existence of a sensing mechanism that controls the transdifferentiation process within each islet. The finding of evidence for islet cell transdifferentiation in rodent and human T1D and its induction by a single peptide in a model of T1D has important implications for the development of β-cell regeneration therapies for diabetes.

Abstract
Type 1 diabetes (T1D) results from autoimmune destruction of pancreatic β-cells. Although Th1 cells are key orchestrators of T1D, the function(s) of the more recently identified Th17 subset are unclear due to inherent plasticity. In this study, we analyzed Th17 cells for stability and diabetogenicity in NOD mice. We found that like Th1 cells, Th17 are a distinct population throughout the prediabetic phase. At diabetes onset, there were marked increases in IL-17-producing Th17 cells and IFN-γ-producing Th1 cells in the pancreas as well as in the serum levels of these cytokines, indicating that these proinflammatory mediators serve as biomarkers of advanced autoimmunity. Although naturally occurring Th17 cells in diabetic mice did not contribute to diabetes development in transfer models, islet-specific Th17 cells were diabetogenic independently of IL-17 and displayed inflammation-induced Th17-to-Th1 reprogramming that could be elicited by Th1 cells. However, an inability to generate Th1 cells because of Stat4, Ifngr, and Ifng deficiencies did not prevent diabetes. Instead, TNF-α could mediate diabetes in response to either Th17 cells or Th1 cells. The results identify a previously unknown mechanism by which Th17 cells can contribute to T1D. Our studies also suggest that when developing interventions for T1D, it will be potentially advantageous to focus on mechanisms common to effector T cells rather than on the signature cytokines of various subsets.

Abstract
T cell migration is crucial for an effective adaptive immune response to invading pathogens. Naive and memory T cells encounter pathogen antigens, become activated, and differentiate into effector cells in secondary lymphoid tissues, and then migrate to the site(s) of infection where they exert effector activities that control and eliminate pathogens. To achieve activation, efficient effector function, and good memory formation, T cells must traffic between lymphoid and non-lymphoid tissues within the body. This complex process is facilitated by chemokine receptors, selectins, CD44, and integrins that mediate the interactions of T cells with the environment. The expression patterns of these migration receptors (MR) dictate the tissues into which the effector T cells migrate and enable them to occupy specific niches within the tissue. While MR have been considered primarily to facilitate cell movement, we highlight how the heterogeneity of signaling through these receptors influences the function and fate of T cells in situ. We explore what drives MR expression heterogeneity, how this affects migration, and how this impacts T cell effector function and memory formation.

Abstract
Successful replication of the influenza A virus requires both viral proteins and host cellular factors. In this study we used a cellular assay to screen for small molecules capable of interfering with any of such necessary viral or cellular components. We used an established reporter assay to assess influenza viral replication by monitoring the activity of co-expressed luciferase. We screened a diverse chemical compound library, resulting in the identification of compound 7, which inhibits a novel yet elusive target. Quantitative real-time PCR studies confirmed the dose-dependent inhibitory activity of compound 7 in a viral replication assay. Furthermore, we showed that compound 7 is effective in rescuing high-dose influenza infection in an in vivo mouse model. As oseltamivir-resistant influenza strains emerge, compound 7 could be further investigated as a new and potentially suitable scaffold for the development of anti-influenza agents that act on novel targets.

Abstract
The early inflammatory response to influenza virus infection contributes to severe lung disease and continues to pose a serious threat to human health. The mechanisms by which neutrophils gain entry to the respiratory tract and their role during pathogenesis remain unclear. Here, we report that neutrophils significantly contributed to morbidity in a pathological mouse model of influenza virus infection. Using extensive immunohistochemistry, bone marrow transfers, and depletion studies, we identified neutrophils as the predominant pulmonary cellular source of the gelatinase matrix metalloprotease (MMP) 9, which is capable of digesting the extracellular matrix. Furthermore, infection of MMP9-deficient mice showed that MMP9 was functionally required for neutrophil migration and control of viral replication in the respiratory tract. Although MMP9 release was toll-like receptor (TLR) signaling-dependent, MyD88-mediated signals in non-hematopoietic cells, rather than neutrophil TLRs themselves, were important for neutrophil migration. These results were extended using multiplex analyses of inflammatory mediators to show that neutrophil chemotactic factor, CCL3, and TNFα were reduced in the Myd88−/− airways. Furthermore, TNFα induced MMP9 secretion by neutrophils and blocking TNFα in vivo reduced neutrophil recruitment after infection. Innate recognition of influenza virus therefore provides the mechanisms to induce recruitment of neutrophils through chemokines and to enable their motility within the tissue via MMP9-mediated cleavage of the basement membrane. Our results demonstrate a previously unknown contribution of MMP9 to influenza virus pathogenesis by mediating excessive neutrophil migration into the respiratory tract in response to viral replication that could be exploited for therapeutic purposes. Influenza-associated morbidity and mortality due to yearly epidemics and sporadic, devastating pandemics are a significant health and economic burden. Severe complications arising from highly virulent viruses are associated with rapid, massive inflammatory cell infiltration. Although neutrophils are the predominant cell population recruited to the lung in response to pandemic influenza viruses, the mechanisms by which they gain entry to the respiratory tract remain unclear. In this study, we show a previously unknown contribution of MMP9 to influenza pathogenesis by mediating excessive neutrophil migration into the lung, which not only controls viral replication, but also contributes to morbidity. The in vivo relevance of MMP9-derived enzymatic activity in neutrophils is controversial and understudied, but our data provide new evidence that innate recognition of influenza virus attracts neutrophils that secrete MMP9, which enables them to traverse the basement membrane of the lung by digesting the extracellular matrix. The dichotomy of MMP9 function in immunity versus pathology provides real challenges for targeting MMP9 for therapeutic purposes. Nevertheless, finding the balance to modulate neutrophil numbers following influenza virus infection will allow for innate immunity to be boosted whilst preventing pathology associated with pandemic strains.

Abstract
Despite the widespread use of the cell-surface receptor CD44 as a marker for antigen (Ag)-experienced, effector and memory T cells, surprisingly little is known regarding its function on these cells. The best-established function of CD44 is the regulation of cell adhesion and migration. As such, the interactions of CD44, primarily with its major ligand, the extracellular matrix (ECM) component hyaluronic acid (HA), can be crucial for the recruitment and function of effector and memory T cells into/within inflamed tissues. However, little is known about the signaling events following engagement of CD44 on T cells and how cooperative interactions of CD44 with other surface receptors affect T cell responses. Recent evidence suggests that the CD44 signaling pathway(s) may be shared with those of other adhesion receptors, and that these provide contextual signals at different anatomical sites to ensure the correct T cell effector responses. Furthermore, CD44 ligation may augment T cell activation after Ag encounter and promote T cell survival, as well as contribute to regulation of the contraction phase of an immune response and the maintenance of tolerance. Once the memory phase is established, CD44 may have a role in ensuring the functional fitness of memory T cells. Thus, the summation of potential signals after CD44 ligation on T cells highlights that migration and adhesion to the ECM can critically impact the development and homeostasis of memory T cells, and may differentially affect subsets of T cells. These aspects of CD44 biology on T cells and how they might be modulated for translational purposes are discussed.

Abstract
Type 1 diabetes (T1D) results from autoimmune destruction of insulin-producing β-cells in the pancreatic islets. There is an immediate need to restore both β-cell function and immune tolerance to control disease progression and ultimately cure T1D. Currently, there is no effective treatment strategy to restore glucose regulation in patients with T1D. FoxP3-expressing CD4(+) regulatory T cells (Tregs) are potential candidates to control autoimmunity because they play a central role in maintaining self-tolerance. However, deficiencies in either naturally occurring Tregs (nTregs) themselves and/or their ability to control pathogenic effector T cells have been associated with T1D. Here, we hypothesize that nTregs can be replaced by FoxP3(+) adaptive Tregs (aTregs), which are uniquely equipped to combat autoreactivity in T1D. Unlike nTregs, aTregs are stable and provide long-lived protection. In this review, we summarize the current understanding of aTregs and their potential for use as an immunological intervention to treat T1D.

Abstract
Type 1 diabetes (T1D) develops as a consequence of a progressive autoimmune response that destroys insulin-producing β-cells in pancreatic islets. Because of their role(s) in controlling immune responses, considerable effort has been directed toward resolving whether regulatory T cells (Tregs) offer a clinical treatment to restore tolerance in T1D. We previously reported that in vitro-induced adaptive Treg cells (aTregs) can reverse T1D and persist as protective memory cells in the NOD mouse model. In the current study, we investigated mechanisms that regulate aTregs. We found that these FoxP3(+) aTregs expressed high levels of the IL-7 receptor, IL-7Rα, without the high affinity receptor for IL-2, CD25, which is found on natural Treg cells (nTregs). IL-7Rα expression was mirrored by the dependency of aTregs on IL-7 for persistence. IL-10 and TGF-β, effector cytokines of aTregs, were not essential for their maintenance at the level of systemic antibody blocking. Nevertheless, IL-10 modulated cytokine production by aTregs and TGF-β was critical for protection. aTregs were found to infiltrate islets and the expression of integrin-β7 was required for their localization in the pancreas. Furthermore, blocking aTreg entry into the pancreas prevented their control of diabetogenic effector T cells, implying the need for local control of the autoimmune response. The distinct homeostatic regulation of aTregs independently of a response to IL-2, which is defective in T1D patients, suggests that these cells represent a translatable candidate to control the autoimmune response.

Abstract
CD44 is a widely-expressed adhesion receptor that is associated with diverse biological processes involving migrating cells, including inflammation, angiogenesis, bone metabolism and wound healing. In the immune system, CD44 is upregulated after activation of naive T lymphocytes during their responses against invading microbes. Once an infection is cleared, elevated levels of CD44 remain on the surface of memory T cells that mediate protection against re-infection. While this has led to the use of highly sustained CD44 expression on T cells as an indicator of a previous immune response, the relevance to T-cell responses or homeostasis has been largely unexplored. Our recent studies demonstrate that CD44 selectively regulates the survival of the Th1 subset of CD4 T cells, but not other T-cell subpopulations. These findings, together with studies of CD44 in other cell types, suggest that differences in the engagement of signaling mechanisms are likely to underlie differential regulation of T-cell responses and underscore the importance of this adhesion receptor to immune cell regulation and protection against viruses and intracellular bacteria.

Abstract
Optimal immunity to microorganisms depends upon the regulated death of clonally expanded effector cells and the survival of a cohort of cells that become memory cells. After activation of naive T cells, CD44, a widely expressed receptor for extracellular matrix components, is upregulated. High expression of CD44 remains on memory cells and despite its wide usage as a "memory marker," its function is unknown. Here we report that CD44 was essential for the generation of memory T helper 1 (Th1) cells by promoting effector cell survival. This dependency was not found in Th2, Th17, or CD8(+) T cells despite similar expression of CD44 and the absence of splice variants in all subsets. CD44 limited Fas-mediated death in Th1 cells and its ligation engaged the phosphoinositide 3-kinase-Akt kinase signaling pathway that regulates cell survival. The difference in CD44-regulated apoptosis resistance in T cell subpopulations has important implications in a broad spectrum of diseases.

Abstract
Type 1 diabetes (T1D) results from autoimmune destruction of insulin-producing pancreatic islet β cells. Previous studies established that the Th1 subset of CD4+ T effector/memory cells plays a central role in the induction of the aoutimmune attack against islet β cells. Using the nonobese diabetes (NOD) mouse model, our recent studies suggested that the Th17 subset CD4+ T effector cells may also play a role in T1D. In an effort to profile the kinetics of effector/memory CD4+ T cell development, we found significant percentages of CD4+ T cells that express effector/memory phenotype (CD44hi CD62L-) in peripheral lymph nodes and spleens of young female NOD mice (2 weeks old). Importantly, we were able to identify islet infiltrating CD4+ T cells in 2-week-old NOD mice, a time point when insulitis cannot be readily detected by histology. Furthermore, intracellular cytokine staining shows that significant proportions of these early infiltrating CD4+ T cells express either IFNγ or IL-17, signature cytokines of Th1 and Th17 subsets of effector/memory cells, respectively. On going efforts are being directed to elucidating how this early effector/memory population of CD4+ T cells develop and to testing the pathogenic potentials of these cells in the NOD model of T1D.

Abstract
Type 1 diabetes is a CD4 cell-dependent disease that results from destruction of insulin-producing beta cells in pancreatic islets. An ideal therapy would reverse diabetes shortly after onset when islet function in not yet fully ablated, and also prevent re-emergence of disease through the generation of memory cells that control the autoimmune response. In this study, we show that adaptive/induced polyclonal regulatory (TR) cells, which contain islet-reactive cells, fulfill these criteria in the NOD mouse model. CD4 cells induced to express FoxP3, IL-10, and TGF-beta1 in response to TCR signaling and TGF-beta1 can reverse diabetes with clinical restoration of prediabetic serum levels of IL-10. Unlike naturally occurring TR cells, these adaptive TR cells persist indefinitely (>1 year) as FoxP3(+), CD25(-) memory cells that self-renew. Establishment of memory is accompanied by narrowing of the T cell repertoire to usage of a single TCR beta-chain, Vbeta11, implying selection by Ag. With islet-specific adaptive TR cells, we show that memory is functionally stable and transferable. Therefore, adaptive TR cells, which can be readily generated from normal CD4 populations and become focused by Ag with induction of memory, may provide a treatment and a vaccine for the long-term cure of diabetes making them attractive as immunotherapeutic agents.

Abstract
Adaptive regulatory T cells that develop from naive CD4 cells in response to exposure to Ag can act as immunotherapeutic agents to control immune responses. We show that effectors generated from murine islet-specific CD4 cells by TCR stimulation with IL-2 and TGF-beta1 have potent suppressive activity. They prevent spontaneous development of type 1 diabetes in NOD mice and inhibit development of pancreatic infiltrates and disease onset orchestrated by Th1 effectors. These regulatory T cells do not require innate CD25+ regulatory cells for generation or function, nor do they share some characteristics typically associated with them, including expression of CD25. However, the adaptive population does acquire the X-linked forkhead/winged helix transcription factor, FoxP3, which is associated with regulatory T cell function and maintains expression in vivo. One mechanism by which they may inhibit Th1 cells is via FasL-dependent cytotoxicity, which occurs in vitro. In vivo, they eliminate Th1 cells in lymphoid tissues, where Fas/FasL interactions potentially play a role because Th1 cells persist when this pathway is blocked. The results suggest that adaptive regulatory CD4 cells may control diabetes in part by impairing the survival of islet-specific Th1 cells, and thereby inhibiting the localization and response of autoaggressive T cells in the pancreatic islets.
