WebOct 20, 2024 · Tolerance Tolerance is a state of specific immunological insensitivity to a particular antigen or epitope despite otherwise normal immune function. Antigens present throughout embryonic development are typically regarded as self and do not provoke an immune response; hence, the host maintains tolerance to these antigens. WebAntigens and the Adaptive Immune Response. Adaptive immunity occurs after exposure to an antigen either from a pathogen or a vaccination. The adaptive, or acquired, immune response takes days or even weeks to become established—much longer than the innate response; however, adaptive immunity is more specific to an invading pathogen.
