Mitochondria-Endoplasmic Reticulum Contact Sites Function as Immunometabolic Hubs that Orchestrate the Rapid Recall Response of Memory CD8+ T Cells

How glucose metabolism enables rapid acquisition of effector function in memory CD8+ T cells remains poorly understood. Bantug et al. demonstrate that mitochondria-endoplasmic reticulum contact sites are signaling hubs that enable the metabolic reprogramming required for rapid CD8+ T cell recall responses.
