Natural killer cell-derived extracellular vesicles in cancer: mediators of intercellular communication and tumor immune signaling
Natural killer (NK) cells are essential components of innate immunity and play a pivotal role in tumor surveillance through direct cytotoxicity and immune regulation. In recent years, NK-cell-derived extracellular vesicles (NK-EVs) have emerged as a promising cell-free therapeutic modality that preserves key antitumor...
