Immune response
Any reaction by the immune system.

immune response n a bodily response to an antigen that occurs when lymphocytes identify the antigenic molecule as foreign and induce the formation of antibodies and lymphocytes capable of reacting with it and rendering it harmless called also immune reaction

* * *

the response of the immune system to antigens. There are two types of immune response produced by two populations of lymphocyte. B-lymphocytes (or B-cells) are responsible for humoral immunity, producing free antibodies that circulate in the bloodstream; and T-lymphocytes (or T-cells) are responsible for cell-mediated immunity (see helper T-cell, cytotoxic T-cell, suppressor T-cell).

* * *

any response of the immune system to an antigenic stimulus, including antibody production, cell-mediated immunity, and immunologic tolerance. The responses causing tissue injury are generally classified into the types described by the Gell and Coombs classification (see under classification). See also hypersensitivity reaction, under reaction.
