Abstract
Cantabria Cohort stems from a research and action initiative lead by researchers from Valdecilla Research Institute (IDIVAL), Marqués de Valdecilla University Hospital and University of Cantabria, supported by the regional Goverment. Its aim is to identify and follow up a cohort that would provide information to improve the understanding of the etiology and prognosis of different acute and chronic diseases. The Cantabria Cohort will recruit between 40,000-50,000 residents aged 40-69 years at baseline, representing 10-20% of the target population. Currently, more than 30,000 volunteers have been enrolled. All participants will be invited for a re-assessment every three years, while the overall duration is planned for twenty years. The repeated collection of biomaterials combined with broad information from participant questionnaires, medical examinations, actual health system records and other secondary public data sources is a major strength of its design, which will make it possible to address biological pathways of disease development, identify new factors involved in health and disease, design new strategies for disease prevention, and advance precision medicine. It is conceived to allow access to a large number of researchers worldwide to boost collaboration and medical research.

Abstract
The inhibition of apoptotic cell death in T cells through the dysregulated expression of BCL2 family members has been associated with the protection against the development of different autoimmune diseases. However, multiple mechanisms were proposed to be responsible for such protective effect. The purpose of this study was to explore the effect of the T-cell overexpression of BCL2A1, an anti-apoptotic BCL2 family member without an effect on cell cycle progression, in the development of collagen-induced arthritis. Our results demonstrated an attenuated development of arthritis in these transgenic mice. The protective effect was unrelated to the suppressive activity of regulatory T cells but it was associated with a defective activation of p38 mitogen-activated protein kinase in CD4+ cells after in vitro TCR stimulation. In addition, the in vitro and in vivo TH17 differentiation were impaired in BCL2A1 transgenic mice. Taken together, we demonstrated here a previously unknown role for BCL2A1 controlling the activation of CD4+ cells and their differentiation into pathogenic proinflammatory TH17 cells and identified BCL2A1 as a potential target in the control of autoimmune/inflammatory diseases.

Abstract
OBJECTIVE Despite the importance of Treg cells in the maintenance of immunologic tolerance, the mechanisms that control their generation and activity are unknown. Since the cell cycle inhibitor p27(Kip1) (p27) was involved in T cell anergy, we undertook this study to explore its role in both Treg cell processes. METHODS The development of type II collagen-induced arthritis (CIA) and lupus-like abnormalities was compared between transgenic mice overexpressing human Bcl-2 in T cells (BCL2-TgT mice) and nontransgenic mice that were deficient or not deficient in p27. The contribution of Treg cells to disease evolution was also explored. Finally, the in vitro activity of Treg cells and their differentiation from naive CD4+ cells was compared between these strains of mice. RESULTS BCL2-TgT mice were protected against CIA by a Treg cell-dependent mechanism. In association with this protection, the overexpression of Bcl-2 in T cells enhanced the differentiation and activity of Treg cells. Both Bcl-2 effects were independent of its antiapoptotic activity but dependent on its capacity to induce the expression of p27 that augmented the strength of transforming growth factor β (TGFβ) signaling in T cells. Accordingly, down-modulation of p27 expression in BCL2-TgT mice promoted CIA. In addition, p27 deficiency in aged C57BL/6 mice reduced the number and activity of Treg cells and induced the development of mild lupus-like abnormalities. CONCLUSION Our results point to p27 as a critical regulator of Treg cell differentiation and function through the positive modulation of TGFβ signaling strength in T cells.

Abstract
Genetic abnormalities predisposing to autoimmunity generally act in a cooperative manner affecting one or several mechanisms regulating immunological tolerance. In addition, many of these genetic abnormalities are also involved in the development of lymphoproliferative diseases. In the present study, we have determined the possible cooperation between deficiencies in members of the Cip/Kip family of cell cycle regulators (p21(WAF1/Cip1) or p27(kip1)) and the overexpression of human Bcl-2 in B lymphocytes in the induction of autoimmune and lymphoproliferative diseases in non-autoimmune C57BL/6 (B6) mice. Unlike single mutant mice, B6.p21(-/-) mice transgenic for human Bcl-2 in B cells developed a lethal autoimmune syndrome characterized by the production of autoantibodies, the prominent expansion of memory B and CD4(+) T cells and the development of severe glomerular lesions resembling IgA nephropathy. Furthermore, these mice presented a high incidence of B-cell lymphoproliferative disorders. Such genetic cooperation in the induction of autoimmunity was not observed in B6.p27(-/-) mice transgenic for human Bcl-2 in B cells. Altogether, what we have demonstrated here is the existence of preferential interactions among particular regulators of the G(1)/S transition of the cell cycle and B-cell survival in the induction of systemic autoimmune and lymphoproliferative diseases.

Abstract
OBJECTIVES The contribution of humoral immune response in allograft and xenograft rejection has been clearly demonstrated in recent years. For this reason, inhibition of alloantibody production has become essential in managing transplanted patients. Here, we assessed the effects of the leflunomide derivative FK778 (FK778) in the control of antibody production resulting from semiallogeneic cognate T-B-cell interactions. MATERIALS AND METHODS BALB/c mice were tolerized at birth with semiallogeneic spleen cells from (BALB/c X C57BL/6) F1 mice, with or without overexpression of human bcl-2 transgene in B cells. These tolerized mice were treated with different dosages of FK778, either from birth, or from the third week of age, when autoantibody production was detected. The production of autoantibodies, used as markers of semiallogeneic cognate T-B - cell interactions, was evaluated at different time points during drug administration or after the interruption of treatment. RESULTS FK778 treatment started at birth inhibited the production of semiallogeneic-driven antibodies in a dose-dependent manner. In addition, FK778 also reduced the levels of preformed circulating autoantibodies in adult mice, although the dosage required was 4 times higher than that used in neonates. However, the levels of IgG antibodies in these tolerized mice increased after FK778 withdrawal, indicating that FK778 failed to induce tolerance to semiallogeneic host CD4+ Th2 and/or donor B cells. CONCLUSIONS Our results demonstrate the efficacy of FK778 in the control of antibody production resulting from semiallogeneic cognate T-B - cell interactions.

Abstract
Regulation of lymphocyte survival is essential for the maintenance of lymphoid homeostasis preventing the development of autoimmune diseases. Recently, we described a systemic lupus erythematosus associated with an IgA nephropathy in autoimmune-prone (NZW x C57BL/6)F(1) overexpressing human Bcl-2 (hBcl-2) in B cells (transgenic (Tg) 1). In the present study, we analyze in detail a second line of hBcl-2 Tg mice overexpressing the transgene in all B cells and in a fraction of CD4(+) and CD8(+) T cells (Tg2). We demonstrate here that the overexpression of hBcl-2 in T cells observed in Tg2 mice is associated with a resistance to the development of lupus disease and collagen type II-induced arthritis in both (NZW x C57BL/6)F(1) and (DBA/1 x C57BL/6)F(1) Tg2 mice, respectively. The disease-protective effect observed in autoimmune-prone Tg2 mice is accompanied by an increase of peripheral CD4(+)CD25(+) hBcl-2(+) regulatory T cells (T(regs)), expressing glucocorticoid-induced TNFR, CTLA-4, and FoxP3. Furthermore, the in vivo depletion of CD4(+)CD25(+) T(regs) in (DBA/1 x C57BL/6)F(1) Tg2 mice promotes the development of a severe collagen type II-induced arthritis. Taken together, our results indicate that the overexpression of hBcl-2 in CD4(+) T cells alters the homeostatic mechanisms controlling the number of CD4(+)CD25(+) T(regs) resulting in the inhibition of autoimmune diseases.

Abstract
Escherichia coli heat-labile enterotoxin (LT) exhibits a broad range of immunomodulatory activities, including the induction of lymphocyte-programmed cell death. However, the nature of the lymphoid populations sensitive to LT-induced apoptosis and the mechanisms used by this toxin to promote such activity are still unclear. In this study, we demonstrate that LT induces in mice a rapid increase in the levels of circulating corticosterone, resulting in a dramatic induction of cell death of immature CD4+CD8+, B220+IgM- and IgM+IgD- T and B cell progenitors, respectively. Apoptosis of these cell populations is similar to that reported after experimental treatment with corticosteroids, it is inhibited by mifepristone, a glucocorticoid receptor antagonist, and does not occur in adrenalectomized animals. These results clearly indicate that endogenous glucocorticoids are the mediators of the LT-induced cell death, which involves Bcl-2-dependent apoptotic pathways. The LT-mediated programmed cell death requires systemic exposure and the enzymatic activity of LT, since a mutant devoid of any enzymatic activity have no pro-apoptotic effect at any dose tested.
