From: Autoimmunity and tumor immunology: two facets of a probabilistic immune system
Conceptual scheme of the immune response. Ags are collected from the environment by specific cells (APCs) that belong to the IIS. Following activation of the IIS by danger signals, probabilistic communication between the IIS and AIS occurs via Ag presentation, permitting the AIS to mount an Ag-specific immune response. The overall immune response is the result of innate and adaptive effector mechanisms.
