Exosomal circular RNAs in the tumor immune microenvironment: From regulatory mechanisms to therapeutic opportunities and translational hurdles (Review).
Immune checkpoint inhibitors have changed cancer treatment, although durable benefit remains limited because malignant, immune and stromal cells sustain suppression within the tumor immune microenvironment. Extracellular vesicles (EVs), including small EVs, can transfer circular RNAs (circRNAs) between defined donor an...
