noun
A biological response involving the natural production of antibodies, macrophages, etc. as in reaction to the presence in the body of bacteria, a poison, or a transplanted organ.
noun
An integrated bodily response to an antigen, in vertebrate animals including the immediate, nonspecific response of the innate immune system followed by the specific response of the adaptive immune system, which involves recognition of antigens by specific antibodies or previously sensitized lymphocytes.
noun
A protective response of the body's immune system to an antigen, especially a microorganism or virus that causes disease. The immune response involves the action of lymphocytes that deactivate antigens either by stimulating the production of antibodies (humoral immune response) or by a direct attack on foreign cells (cell-mediated immune response.) An inability to produce a normal immune response results in immunodeficiency diseases such as AIDS.
