Lymphocytes That Transform Into Plasma Cells And Secrete Antibodies, Plasma cells often leave the secondary lymphoid organs, where the Activated B cells differentiate into plasma cells, which secrete the immunoglobulins (antibodies) that drive acquired humoral immunity and serve to destroy extracellular pathogens and Plasma cells represent the terminally differentiated stage of B lymphocytes, serving as the body's dedicated factories for antibody production. Plasma cells often leave the secondary lymphoid organs, where the response is generated, and migrate back to After B cells are activated by their binding to antigen, they differentiate into plasma cells. These cells are most recognizable for their Eventually, the plasma cells secrete antibodies with antigenic specificity identical to those that were on the surfaces of the selected B cells. The remaining clones serve as a memory The ability to clonally proliferate or differentiate into plasma cells and secrete antibodies strain the metaphor even further, as most field officers are terminally differentiated and do not secrete B cells, also known as B lymphocytes, are a type of lymphocyte. Once a B cell is activated, it undergoes clonal proliferation and daughter cells differentiate into plasma cells. Notice in the figure that B cells are the leukocytes or white blood cells that transform into plasma cells that function to synthesize specialized antibodies that bind to the antigens or foreign invaders of the body. These are usually Eventually, the plasma cells secrete antibodies with antigenic specificity identical to those that were on the surfaces of the selected B cells. [1] They function in the humoral immunity component of the adaptive immune system. Notice in the figure that The terminal differentiation of B cells generates short-lived plasmablasts and long-lived plasma cells, both of which secrete antibodies. Some clonal One study of affinity maturation in antibody-secreting versus memory cells suggests that expression of high-affinity antibody may favor plasma cell rather than memory cell development 34. After B cells are activated by their binding to antigen, they differentiate into plasma cells. 4 The Adaptive Immune Response: B Lymphocytes and Antibodies Learning Objectives By the end of this section, you will be able to: Explain how B cells mature and Plasma cells contribute to neuroinflammation by producing antibodies that target central nervous system (CNS) components, leading to immune-mediated Eventually, the plasma cells secrete antibodies with antigenic specificity identical to those that were on the surfaces of the selected B cells. Plasma Cell: A type of B cell that produces most of the antibodies Clonal selection of a B cell Activated by the binding of an antigen to a specific matching receptor on its surface, a B cell proliferates into a clone. Plasma cells often leave the secondary lymphoid organs, where the response is generated, and migrate back to Once a B cell is activated, it undergoes clonal proliferation and daughter cells differentiate into plasma cells.
