Cover Story: The coordination of ICI therapy and the gut microbiota triggers a synergistic anti-tumour immune response. The inflammation induced by ICI promotes the uptake of gut microbiota by the intestinal dendritic cells (DCs), leading to the upregulation of MHC, CD86, and CCR7, which facilitates the transport of microbiota-loaded DCs into the MLNs. Additionally, ICI therapy induces lymphangiogenesis and the dilation of high endothelial venules in the MLNs, enhancing the translocation of bacteria to the TDLNs and the tumour itself. In the TME, the microbiota modifies the intrinsic tumour factors and influences the anti-tumour immune response, resulting in increased leukocyte infiltration and enhanced secretion of Granzyme B and perforin by the effector immune cells, such as CD8 killer T cells and NKT cells, ultimately driving tumour elimination.
