Advances in signal regulation and detection strategies for autophagy in fungal cells

Autophagy is a widespread and unique degradation process in eukaryotic cells. When cells are under various stress conditions such as nutritional deficiencies, growth factor deficiencies or hypoxia, autophagy will be initiated to maintain the stability of the internal environment and ensure normal proliferation and differentiation. At present, research on autophagy-related targets is mostly focused on tumor cells. In contrast, research on fungal autophagy targets is still limited. Autophagy plays an important role in growth, development and morphological changes of fungal cells, suggesting that research on fungal autophagy as a drug target should be useful. This article reviews the signal regulation and detection strategies for autophagy in fungal cells, and provides a research basis for the screening of antifungal drugs targeting autophagy-related proteins.
