IL-17-producing CD4 T cells (Th17 cells) are understood to be a distinct lineage of CD4 T helper (Th) cells, which play an important role in the host defense, tissue inflammation and autoimmunity. The identification of Th17 cells collapsed the concept of the previously held Th1/Th2 paradigm in infection and autoimmunity. Recent studies have provided new information on the role of Th17 cells in ...
The transcription factor Early Growth Response 3 (Egr3) has been shown to play an important role in negatively regulating T cell activation and promoting T cell anergy in Th1 cells. However, its role in regulating other T helper subsets has yet to be described. We sought to determine the role of Egr3 in a Th17 response using transgenic mice that overexpress Egr3 in T cells (Egr3 TG). Splenocyte...
The immunological pathogenesis of diffuse large B cell lymphoma (DLBCL) remains elusive. Searching for new prognostic markers of DLBCL is a crucial focal point for clinical scientists. The aim of the present study was to examine the prognostic value of interferon regulatory factor 8 (IRF8) expression and its effect on the development of Th17 cells in the tumor microenvironment of DLBCL patients...
Traditionally, Crohn's disease has been associated with a Th1 cytokine profile, while Th2 cytokines are modulators of ulcerative colitis. This concept has been challenged by the description of tolerising regulatory T cells (Treg) and by proinflammatory Th17 cells, a novel T cell population characterised by the master transcription factor RORgammat, the surface markers IL23R and CCR6, and by pro...
We propose that deregulated T-helper-cell (Th) signaling underlies evolving Th17 cytokine expression seen during progression of cutaneous T-cell lymphoma (CTCL). Accordingly, we developed a lymphoma progression model comprising cell lines established at indolent (MAC-1) and aggressive (MAC-2A) CTCL stages. We discovered activating JAK3 (V722I) mutations present at indolent disease, reinforced i...
1589 Single-cell RNA sequencing analysis of human psoriatic skin with SLE treated with IL23 blockade
Systemic lupus erythematosus (SLE) and psoriasis are both chronic immune-mediated diseases. SLE is caused by T-helper 1 (Th1), Th2, Th17, B cell axis activation, while primarily driven Th17 activation. Coexistent has been reported. A phase II trial of patients with active demonstrated that ustekinumab (interleukin (IL)12 23 blockade) resulted in significant Responder Index improvement when adde...
Activation of serum complement triggers Th17 cell-dependent spontaneous autoimmune disease in an animal model. In genetically autoimmune-prone SKG mice, administration of mannan or beta-glucan, both of which activate serum complement, evoked Th17 cell-mediated chronic autoimmune arthritis. C5a, a chief component of complement activation produced via all three complement pathways (i.e., lectin, ...
Myelin-specific T helper 17 cells promote adult hippocampal neurogenesis through indirect mechanisms
CD4 + T cells provide a neuro-immunological link in the regulation of adult hippocampal neurogenesis, but the exact mechanisms underlying enhanced neural precursor cell proliferation and the relative contribution of different T helper (Th) cell subsets have remained unclear. Here, we explored the pro-proliferative potential of interleukin 17-producing T helper (Th17) cells, a developmentally an...
Retinoic-acid-orphan-receptor-C (RORC) is a master regulator of Th17 cells, which are pathogenic in several autoimmune diseases. Genetic Rorc deficiency in mice, while preventing autoimmunity, causes early lethality due to metastatic thymic T cell lymphomas. We sought to determine whether pharmacological RORC inhibition could be an effective and safe therapy for autoimmune diseases by evaluatin...
Activation of CD4+ T cells results in rapid proliferation and differentiation into effector and regulatory subsets. CD4+ effector T cell (Teff) (Th1 and Th17) and Treg subsets are metabolically distinct, yet the specific metabolic differences that modify T cell populations are uncertain. Here, we evaluated CD4+ T cell populations in murine models and determined that inflammatory Teffs maintain ...
