Tumor-derived microparticles promote the progression of triple-negative breast cancer via PD-L1-associated immune suppression

Membrane vesicles, including exosomes and microparticles (MPs), serve to package and transfer the cellular cargo during inter/extracellular communication, which is of great interest in cancer development, especially in the dissemination of signal transduction-associated traits from donor cells to recipient cells. Although increasing evidence suggests that microparticles (MPs) contribute to the development of cancer, their unique characteristics...
