Witryna14 kwi 2024 · Sigma 1 receptor (S1R) is a unique drug-binding site that is commonly expressed in malignant breast epithelial cells and breast cancer cells [ 247 ]. Of interest, inhibition of S1R promotes autophagic flux, resulting in reduced levels of cell surface PD-L1, which succumbs to autophagic degradation [ 248 ].
