Humoral immunity is the aspect of immunity that is mediated by macromolecules – including secreted antibodies, complement proteins, and certain antimicrobial peptides – located in extracellular fluids.

Dec 28, 2020 · Humoral immunity or antibody-mediated immunity protects the body from pathogens and foreign substances in two stages: primary and secondary.

Humoral immunity is mediated by antibodies. It shows a quick response against pathogens. It is the major defence mechanism against extracellular microbes trying to invade the host systems. The antibodies produced by the B-cells bind to the antigens and neutralize the microbes.

May 29, 2023 · Humoral immunity is a form of adaptive immunity whereby B-lymphocytes and plasma cells produce antibodies against antigens and stimulate T-lymphocytes to attack them. These antibodies also stimulate the release of chemical mediators (e.g., interferon and complement) that enhance antigen destruction.

Jan 7, 2022 · Humoral immunity and cell-mediated immunity are two forms of adaptive immune responses that allow the human body to protect itself against dangerous agents including bacteria, viruses, and...

Type of Immune response: Humoral immunity produces an antibody-mediated immune response, whereas cellular immunity produces a cell-mediated immune response. Regulation of Immunity: B cell mainly regulates the humoral immunity, whereas T cell regulates cellular immunity.

The extracellular spaces are protected by the humoral immune response, in which antibodies produced by B cells cause the destruction of extracellular microorganisms and prevent the spread of intracellular infections.
