Differentiation and maintenance of long-lived plasma cells
Webcells and memory B cells. Immediate protection against re-infection is mediated by long-lived plasma cells that are present in the bone marrow and secrete antibodies in an antigen-in-dependent fashion. Recall responses are mediated by memory B cells that rapidly proliferate and differentiate in response to antigenic stimulation (1, 2). WebActivated B cells proliferate and differentiate into antibody-producing cells, long-lived plasma cells, and memory B cells after immunization or infection. Repeated encounter of the same antigen triggers the rapid re-activation of pre-existing specific memory B cells, which then potentially enter new germinal center reactions and differentiate into short … trimming beard after 3 weeks
