7.1 Transgenic overexpression of CREM alpha in murine T cells results in an anergic phenotype with enhanced IL17 production
Results As expected, overall T cell proliferation in naive T cells as response to different stimuli like anti-CD3 or an allogenic MLR was diminished in CREMa transgenic mice compared to wildtype mice, however-unexpectedly – disease activity in a contact dermatitis model was more severe in transgenic mice. Moreover, when T cells purified from the lymphnodes of the challenged ears were used for p...
متن کاملCREM Alpha Enhances IL-21 Production in T Cells In Vivo and In Vitro
The cAMP-responsive element modulator alpha (CREMα) plays a role in autoimmunity and, in particular, in systemic lupus erythematosus. CREMα negatively regulates IL-2 transcription and activates IL-17 expression by direct transcriptional mechanisms. To understand the role of CREM in autoimmunity, we recently generated a mouse with a transgenic overexpression of CREMα selectively in T cells. This...
متن کاملAnergic T cells are metabolically anergic.
Full T cell activation requires TCR engagement (signal 1) in the context of costimulation (signal 2). Costimulation is required for maximal expression of effector cytokines and prevention of T cell anergy. It has become increasingly clear that another major function of costimulation is to up-regulate the metabolic machinery necessary for T cell function. In this report we demonstrate that anerg...
متن کاملOverexpression of Endometrial Estrogen Receptor-Alpha in The Window of Implantation in Women with Unexplained Infertility
Objective Background: Failure in the endometrial receptivity may account for a significant number of infertility cases including unexplained infertility in women. Reduction in the endometrial estrogen receptor-alpha (ER-α) expression during window of implantation may be a critical event that coincides with expression of specific genes and providing a receptive endometrium. The aim of present st...
متن کاملFingerprints of anergic T cells
Peripheral T cell tolerance may result from activation-induced cell death [1], anergy [1], and/or immune response modulation by regulatory T cells [2]. In mice that express a transgenic receptor specific for peptide 111-119 of influenza hemagglutinin presented by E(d) class II MHC molecules as well as hemagglutinin under control of the immunoglobulin-kappa promoter, we have found that anergic T...
