CD4+ CD25+ Foxp3+ regulatory T cells (Tregs) are highly sensitive to IL-2, one of the many cytokines produced during immune responses, for their development, survival and functions. Although effects IL-2 administration on Tregs in vivo well characterized, elicited by an response have not been elucidated. Hence, this study, Treg behaviour IL-2–producing responses was explored using vitro murine ...
