The balancing act of AKT in T cells

Abstract

The serine/threonine-specific protein kinase AKT is gaining recognition as a major crossroad in numerous cellular signaling pathways through its ability to regulate cell differentiation, proliferation, survival and metabolism. This review focuses on the recent advances in AKT signaling and downstream events in T cells, emphasizing its contrasting role in conventional and regulatory (Treg) Tcell populations. Activation of AKT has been known for many years to be critical in the development and function of conventional Tcells. However, it has just recently been uncovered that AKTexerts an inhibitory effect on Treg generation and suppressor function. These studies have placed AKTat the nexus of Treg development and function, thus opening novel avenues for therapeutic manipulation.
