HLA-C and neoplasm: DCs circulate in the body; when they capture the foreign antigens, they will be activated and present the antigens to the lymphocytes, such as T cells and B cells, to activate them.[58] In addition, DCs participate in both innate immune response and adaptive immune response and become a bridge connecting the innate immune response and adaptive immune response.[59] When a tumor occurs in the body, DCs infiltrate solid tumors and capture and process these antigens to a complex with major histocompatibility complex (MHC) molecules.
