Humoral immunity


Humoral immunity refers to antibody production, and all the accessory processes that accompany it: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.

Humoral immunity is mediated by secreted antibodies, produced in cells of the B lymphocyte lineage (B cell). Secreted antibodies bind to antigens on the surfaces of invading microbes, which flags them for destruction.

Antibody-mediated (humoral immunity)
Antibody-mediated (humoral) immunity is regulated by B cells and the antibodies they produce. Cell-mediated immunity is controlled by T cells.

Many scientists are examining strategies for generating cellular and humoral immunity; for example, live non-pathogenic bacteria or viruses can be engineered to express HIV antigens.

responsible for antigen-specific humoral immunity as part of the adaptive immunity. Their antigen receptors are surface immunoglobulins (antibodies). They recognize peptides directly and secrete antibodies by differentiating into plasma cells.

antibody-mediated immunity. Antibodies, dissolved in blood, lymph, and other body fluids bind the antigen and trigger a response to it. (This form of immunity is also called humoral immunity.)
