IL-2-inducible T cell kinase (ITK) is a key signaling mediator downstream of TCR,
mediating T cell positive selection, as well as innate T cell and CD4(+) Th2/Th17
differentiation. In this article, we show that ITK also negatively tunes
IL-2-induced expansion of conventional Foxp3-expressing regulatory T cells
(Tregs). In vivo, Treg abundance is inversely correlated with ITK expression, and
inducible Treg development is inversely dependent on ITK kinase activity. While
Treg development normally requires both hematopoietic and thymic MHC class 2
(MHC2) expression, the absence of ITK allows Treg development with MHC2
expression in either compartment, with preference for selection by thymic MHC2,
suggesting a gatekeeper role for ITK in ensuring that only Tregs selected by both
thymic and hematopoietic MHC2 survive selection. Although ITK suppresses Treg
development and is not required for maintenance of neuropilin-1-positive natural
Tregs in the periphery, it is indispensable for Treg functional suppression of
naive CD4(+) T cell-induced colitis in Rag(-/-) recipients. ITK thus regulates
the development and function of Tregs.
