Tuberous Sclerosis 1 Promotes Invariant NKT Cell Anergy and Inhibits Invariant NKT Cell–Mediated Antitumor Immunity

Development of effective immune therapies for cancer patients requires better understanding of hurdles that prevent the generation of effective antitumor immune responses. Administration of α-galactosylceramide (α-GalCer) in animals enhances antitumor immunity via activation of the invariant NKT (iNKT) cells. However, repeated injections of α-GalCer result in long-term unresponsiveness or anergy of iNKT cells, severely limiting its efficacy in...
