In addition, because of its nanoscale size, MSN facilitates the internalization of CDG by endocytosis, thus promoting the intracellular delivery of loaded CDG and the secretion of a series of pro-inflammatory cytokines by inducing the activation of the STING pathway and the maturation and activation of antigen-presenting cells, further increasing the intensity of T-cell anti-tumor immune response. Here, STING1 is linked to neoplasm.
