Regulatory T (Treg) cells enforce T cell homeostasis and maintain peripheral T cell tolerance. Here we report a previously unappreciated phenomenon of acute T cell lymphopenia in secondary lymphoid organs and non-lymphoid tissues triggered by Treg cell depletion that precedes the expansion of self-reactive T cells. Lymphopenia affects both neonates and adults indicating a dominant role of Treg ...
background: regulatory t cells have been suggested to have a protective role against acute rejection in allograft recipients. however, there is little information available about their contribution to chronic rejection process. the role of transforming growth factor-beta 1 (tgf- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. objectives: to eva...
Background: Euphorbia plants are traditionally used in folk medicine for infections, inflammation, and cancer. Objectives: To investigate the effects of the butanolic extracts of Euphorbia micorociadia and Euphorbia osyridea on specific transcription factors and cytokines expression of T cell subsets. Methods: Activated mouse splenocytes were cultured in the presence of non-cytotoxic concentrat...
Regulatory T cells (CD4(+)CD25(hi)CD127(lo)FOXP3(+) T cells [Tregs]) are a population of lymphocytes involved in the maintenance of self-tolerance. Abnormalities in function or number of Tregs are a feature of autoimmune diseases in humans. The ability to expand functional Tregs ex vivo makes them ideal candidates for autologous cell therapy to treat human autoimmune diseases and to induce tole...
