Web7 apr. 2024 · Primary immune thrombocytopenia (ITP) is characterized for the skewed Th differentiation towards Th1 and Th17 cells as well as the impaired number and function of regulatory T cells (Tregs). Tregs are capable of co-expressing effector Th markers in different inflammatory milieu, which probably indicates Treg dysfunction and … WebWith bead-based activation, IL-2 levels peaked at 24 hours and then declined over subsequent timepoints, whereas with tetramer-based activation, IL-2 levels increased markedly between the 24- and 48-hour timepoints, appearing to plateau somewhat at the 72-hour timepoint. WebInterestingly, loss of RIPK1 kinase activity impaired CD25 expression of activated T cells. Supplementation with recombinant IL-2 restored normal CD25 expression and survival of activated T cells. Our results show that RIPK1 regulates lymphocyte survival and homeostasis of T cells at different developmental stages through distinct mechanisms. the hole watch
