PYGBacking on glycogen metabolism to fuel early memory T cell recall responses

Mol Cell. 2022 Aug 18;82(16):2918-2921. doi: 10.1016/j.molcel.2022.07.016.

Abstract

Zhang et al. (2022) show that TCR signaling promotes the phosphorylation and activation of glycogen phosphorylase B (PYGB) in CD8+ memory T (Tmem) cells. PYGB-dependent glycogen mobilization provides a carbon source to support glycolysis and early Tmem cell recall responses.
