However, tumours may as well elicit a partial immunodeficiency to avoid the development of a complete and active immune response.

Main objective of this study is to outline the basic features of the immune response inside the Central Nervous System, the strategies employed by astrocytic tumours to evade body defences, and to provide an extended literature review on research on immunotherapy, especially concerning its patho-physiology and the clinical results achieved till date.
