- When these memory cells meet their specific antigen again, they rapidly proliferate and differentiate into plasma cells. These plasma cells then respond by producing abundant quantities of antibody to clear the antigen. A subset of these memory cells can also go into the germinal centres for further class switching and affinity maturation.

Jan 17, 2022 · Memory B and T-cells are antigen-specific and, on encountering the antigen again, can mount a more rapid and effective immune response, known as the secondary immune response. This article will discuss memory lymphocytes, active and passive memory, the differences between the two immune responses and finally, clinical correlations.

Nov 29, 2018 · The production of pathogen‐specific B cells and antibodies underlies protective immunity elicited by most vaccines and many infections. Humoral immunity follows a regulated process by which high‐affinity antibody‐secreting plasma cells and memory B cells are generated.

Immunological memory is the ability of the immune system to respond more rapidly and effectively to pathogens that have been encountered previously, and reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes.

Jul 31, 2022 · During the primary immune response, memory cells do not respond to antigens and do not contribute to host defenses. As the infection is cleared and pathogenic stimuli subside, the effectors are no longer needed, and they undergo apoptosis.
Immunological memory is the ability of the immune system to quickly and specifically recognize an antigen that the body has previously encountered and initiate a corresponding immune response. Generally, they are secondary, tertiary and other subsequent immune responses to the same antigen.
Jun 18, 2019 · Immunological memory is defined as the ability of immune cells to specifically ‘remember’ the first encounter with a given antigen and to mount a secondary response that is faster and greater...
Feb 2, 2016 · First, memory immune cells should be long-lived and maintained independently of stimulation or persistence of antigen, either through homeostatic turnover or long-term stable maintenance....
