#WeekendRead! #SmartTumor #EveryCellIsAnImmuneCell! Levy & (many) friends show @cp-cell.bsky.social that melanoma tumors release large extracellular vesicles #melanosomes decorated with MHC-I & high affinity tumor associated antigens which subvert cytotoxic T cells! www.cell.com/cell/fulltex...
HLA export by melanoma cells decoys cytotoxic T cells to promote immune evasion
Melanoma cells escape immune surveillance by releasing MHC-antigen-loaded large EVs, known as melanosomes, that directly engage and impair CD8+ T cell receptors.
