Summary of proposed mechanisms of GBM immunosuppression. Immunosuppressive effects are categorized as either systemic (on left) or local (right). Systemic effects are exerted on either the blood and lymphopoietic systems (including the bone marrow) or secondary lymphoid organs, including the spleen. Local effects include effects on both the adaptive and innate immune systems. Specific examples are included in each panel.
