AMBRA1 is involved in T cell receptor-mediated metabolic reprogramming through an ATG7-independent pathway.

Metabolic reprogramming contributes to dynamic alteration of cell functions and characteristics. In T cells, TCR-mediated signaling evokes metabolic reprogramming and autophagy. AMBRA1 is known to serve in the facilitation of autophagy and quality control of mitochondria, but the role of AMBRA1 in T cell metabolic alteration is unknown.
