Targeting Autophagy to Overcome Chemoresistance and Immune Resistance in Triple-Negative Breast Cancer

Triple-negative breast cancer (TNBC) remains one of the most challenging subtypes of breast cancer to treat, defined by its molecular heterogeneity, absence of hormone receptors, and poor clinical outcomes. While this difficulty with cancer cells persists even in the presence of chemotherapy and immune checkpoint inhibitors (ICIs), one critical factor linked to both chemoresistance and immune escape is autophagy. Autophagy is a cellular process with lysosomal recycling function. In TNBC, autopha
