Abstract
Modifying T cell metabolism and activating conserved stress pathways can enhance T cell efficacy in adoptive cell therapy for cancer treatment. Here, we present a protocol to activate the General Control Non-depressible 2 (GCN2)-mediated branch of the integrated stress response (ISR) in murine T cells using the drug halofuginone. We outline the process of isolating CD8+ T cells from T cell receptor transgenic mice, activating them with bone-marrow-derived dendritic cells, and subsequently activating GCN2 and the ISR with halofuginone. For complete details on the use and execution of this protocol, please refer to St. Paul et al.1.
