Detailed explanation-1: -Humoral immunity relies on the induction of antigen-specific B cells and resulting production and secretion of antibodies specific for the antigen.
Detailed explanation-2: -Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin, or antibody. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.
Detailed explanation-3: -Plasma cells (PC) represent an essential arm in humoral immunity as the main line of defense against infection and re-infection. As the primary producers of circulating immunoglobulin (Ig), these cells provide vital durable and protective immunity against a multitude of pathogens.
Detailed explanation-4: -Humoral immunity B cell lymphocytes, a type of immune cell that makes antibodies after detecting a specific antigen, are principally responsible for this method. Lymphocytes known as naive B cells circulate throughout the body via the lymphatic system.
