Humoral Immunity
combats pathogens via antibodies
Humoral immunity is a type of immunity mediated by antibodies that are secreted by B cells. These antibodies can bind to antigens present on the surface of pathogens in the extracellular fluid or on the surface of infected cells. The primary function of humoral immunity is to neutralize or eliminate pathogens before they have a chance to invade host cells and cause damage.
The process of humoral immunity begins with the activation of B cells by binding to specific antigens. Once activated, B cells differentiate into plasma cells, which are specialized cells that produce large quantities of antibodies that are specific to the antigen. These antibodies bind to antigens on the surface of the pathogen, marking it for destruction by other immune cells.
In addition to producing antibodies, B cells also develop into memory cells. These cells are capable of “remembering” specific pathogen antigens and quickly responding to future infections by producing a rapid and potent antibody response.
Humoral immunity is essential for protecting against bacterial infections, viral infections, and toxins. Vaccines work by stimulating the production of antibodies against specific pathogens, allowing the immune system to quickly recognize and eliminate any potential future infections.
Overall, humoral immunity is an essential component of the immune system that helps to prevent infections and maintain overall health.
