These genes included key immune modulators, such as Cxcl9 and Cxcl10, responsible for recruiting CD8+ T cells (48–50), and H2-K1 and H2-D1, encoding MHC class I (MHC-I) genes crucial for antigen presentation and thus tumor recognition by CD8+ T cells (51). The gene discussed is CXCL9; the disease is neoplasm.
