To Be {gamma}{delta} or Not to Be {gamma}{delta}? Signaling Pathways in {alpha}β Versus {gamma}{delta} T Cell Maturation

Abstract: Maturation of T cells in the thymus involves input from a number of signaling pathways; their combined input determines whether thymic precursor cells will differentiate into mature {alpha}β or {gamma}{delta} T cells. This Journal Club article highlights recent research showing that the role of Notch signaling in human T cell maturation differs from that in mice. In mice, reducing Notch gene dosage in vivo promotes {gamma}{delta} T cell differentiation. In humans, an increase in Notch activity early in development will trigger {gamma}{delta} T cell development. This research emphasizes how the molecular events controlling T cell development are fundamentally different in humans and mice.
