Hello, everyone! Could you tell me what is exactly "humoral immunity"?
Humoral immunity is one of the mechanisms for the realization of the protective properties of the body in a liquid medium. Unlike cellular immunity, humoral immunity protects the extracellular spaces. The division into cellular and humoral immunity is rather arbitrary, since it is an interconnected system.
It is the synthesis of antibodies by B-lymphocytes in the blood plasma in response to the appearance of foreign antigens. Antibodies are able to bind to pathogens or toxins, neutralizing them, assisting in absorption by phagocytes (opsonization) or through the activation of the complementary system, and their distribution in various body fluids, including blood, secreted mucus and intercellular fluid, provides complete protection.
Interestingly, in addition to antibodies, are there other components of humoral immunity, for example, interleukins?
