N2 - The innate immune system encompasses natural killer (NK) cells, macrophages and granulocytes, the complement system and antimicrobial peptides. Recognition pathways of the innate immune system include microbial non-self recognition, missing-self recognition and induced- self recognition. The central nervous system (CNS) participates in responses of the innate immune system. However, immune inhibitory and anti-inflammatory mechanisms physiologically outbalance and counteract immune activity and thereby limit immune-mediated tissue damage in the brain. Human gliomas appear to take advantage of this immunosuppressive milieu. Moreover, glioma cells themselves interfere with anti-tumor immune responses by expressing immune inhibitory cell surface molecules, such as HLA-G, or by releasing soluble immunosuppressants such as transforming growth factor (TGF)-beta. Yet, although glioma cells exhibit all cellular features of malignancy, these tumors very rarely metastasize outside the brain, raising the possibility of immune-mediated control of these cells outside, but not inside, the brain. Accordingly, activating the innate immune system by forcing glioma cells to express danger signals such as NKG2D ligands is a promising strategy of immunotherapy for these tumors.
