Autophagy in tumour immunity and therapy

Autophagy is induced by stress signals in cancer cells as well as immune cells in the tumour microenvironment. This Review discusses how autophagy modulates antitumour immunity in cancer cell autonomous and non-autonomous ways, and potential approaches for targeting autophagy to enhance the antitumour immune response. Autophagy is a regulated mechanism that removes unnecessary or dysfunctional cellular components and recycles metabolic substrates. In response to stress signals in the tumour microenvironment, the autophagy pathway is altered in tumour cells and immune cells - thereby differentially affecting tumour progression, immunity and therapy. In this Review, we summarize our current understanding of the immunologically associated roles and modes of action of the autophagy pathway in cancer progression and therapy, and discuss potential approaches targeting autophagy to enhance antitumour immunity and improve the efficacy of current cancer therapy.

Automated summary

Autophagy plays a crucial role in cancer by influencing tumor progression, immune responses, and therapy outcomes. Modulating the autophagy pathway can enhance antitumor immune responses and improve treatment efficacy.
