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.

2020年12月28日 · Humoral immunity or antibody-mediated immunity protects the body from pathogens and foreign substances in two stages: primary and secondary.

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.

2022年1月7日 · 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...

2023年5月29日 · 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.

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.

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.

2024年4月10日 · Humoral immunity, also known as the humoral immune response, refers to the branch of the immune system that produces antibodies in response to extracellular pathogens and foreign substances, primarily mediated by B-lymphocytes and plasma cells in the body’s extracellular fluids.

2024年11月23日 · The humoral immune response fights pathogens that are free in the bodily fluids, or “humours”. It relies on antigens (which are also often free in the humours) to detect these pathogens. An antigen is a biomolecule, such as a protein or …

Humoral immune responses are crucial for protection against invading pathogens and are the underlying mechanism of protection for most successful vaccines. Our understanding of how humoral immunity develops is largely based upon animal models utilizing experimental immunization systems.
