IFNγ Helps CBLB-Deficient CD8+ T Cells to Put Up Resistance to Tregs.

In this issue, Han and colleagues demonstrate in preclinical cancer models that genetic deletion of the E3 ubiquitin ligase Cbl proto-oncogene B (CBLB) in adoptively transferred CD8+ T cells induces resistance to regulatory T cells. CBLB deletion induces IFNγ and downmodulates TGFβ/SMAD signaling. This ultimately enforces these cells to be way more effective against various cancers. See related article by Han et al., p. 437 (4).
