HTLV-1 is the causative agent for a neurologic disease named HTLV-I- associated myelopathy/tropical spastic paraparesis (HAM/TSP). Paraparesis of the lower limbs which appears gradually is the most common clinical feature of this disease. It has been shown that the indirect involvement of the nervous system by lymphocytes is more probable than the direct attack of the virus to the neurons. HTLV...
Regulatory T cells (T(regs)) are a subset of T cells that are responsible for maintaining peripheral immune tolerance and homeostasis. The hallmark of T(regs) is the expression of the forkhead box P3 (FoxP3) transcription factor. Natural regulatory T cells (nT(regs)) are a distinct population of T cells that express CD4 and FoxP3. nTregs develop in the thymus and function in maintaining periphe...
Protein kinase B (PKB)/Akt signals control T cell proliferation and differentiation but their effect on the generation and function of regulatory T cells (Treg) and Th17 cells is not well understood. In this study, we show that elevated PKB signals antagonize the immunosuppressive effect of TGF-beta1 on cell size, CD25 and CD98 expression, and proliferation of CD3-stimulated naive CD4(+) T cell...
Objective(s): Multiple sclerosis (MS) is considered as a chronic type of an inflammatory disease characterized by loss of myelin of CNS.Recent evidence indicates that Interleukin 17 (IL-17)-producing T helper cells (Th17 cells) population are increased and regulatory T cells (Treg cells) are decreased in MS. Despite extensive research in understanding the mechanism of Th17 and Treg differentiat...
T cell Ig domain and mucin domain (TIM)-3 has previously been established as a central regulator of Th1 responses and immune tolerance. In this study, we examined its functions in allograft rejection in a murine model of vascularized cardiac transplantation. TIM-3 was constitutively expressed on dendritic cells and natural regulatory T cells (Tregs) but only detected on CD4(+)FoxP3(-) and CD8(+...
