STING1 and neoplasm: Recently, Zhang et al. [40] constructed mannose-modified stearic acid-grafted chitosan (M-CS-SA) micelles dedicated to the activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon gene (STING) signaling pathway and the maturation of dendritic cells (DCs), giving rise to the roles of chitosan in building the anti-tumor cellular immune response.
