Abstract

Notch signaling has been identified as an important regulator of leukocyte differentiation and thymic maturation. Less is known about the role of Notch signaling in regulating mature T cells. We examined the role of Notch 1 in regulating peripheral T cell activity in vitro and in vivo. Coligation of Notch 1 together with TCR and CD28 resulted in a dramatic inhibition of T cell activation, proliferation, and cytokine production. This effect was dependent on presenilin activity and induced the expression of HES-1, suggestive of Notch 1 signaling. Biochemical analysis demonstrated an inhibition of AKT and GSK3β phosphorylation following Notch 1 engagement while other biochemical signals such as TCR and ERK phosphorylation remained intact. Similar effects were observed in vivo in an adoptive transfer model. Therefore, Notch 1 signaling may play an important role in regulating naive T cell activation and homeostasis.
