Prohibitin 2 is a key regulator of T cell proliferation, differentiation, and effector functions in vivo.
Mitochondrial health directly controls T cell function, opening new approaches to boost cancer immunotherapy.
Using conditional T cell-specific knockout models, this Communications Biology study demonstrated that mitochondrial prohibitin 2 is required for proper T cell activation, differentiation into effector subsets, and cytokine secretion, linking mitochondrial protein quality control to adaptive immunity. These findings open avenues for targeting mitochondrial homeostasis to modulate T cell-based cancer immunotherapy or autoimmunity.
