The stimulatory roles of EVs in lung cancer immunity. (a) Heat stressed, (b) Rab27a overexpressed, and (c) CD40L overexpressed lung cancer cell–derived exosomes (TEXs) can activate DC maturation and arouse specific antitumor immunity. (d) Activated dendritic cell–derived exosomes (DEXs) can present antigens to T-cells directly or by transferring pMHC to other immature dendritic cells and amplifing this antigen-presentation effect. TCR, T-cell receptor. Figure created with BioRender.com.
