Modification of photocarcinogenesis by two immunosuppressive agents.

abstract：:Autophagy plays a critical role in intracellular metabolism and maintaining cellular homeostasis. Certain tumor cells present a higher basal autophagy rate and autophagy inhibition can lead to impaired metabolic dysfunction in autophagy-dependent tumor cells. Autophagy status in immune cells dictates their fate and re...
