WebThe cell-surface receptors have two functions: they initiate the phagocytosisof the pathogen, and they stimulate a program of geneexpressionin the host cell for stimulating innate immune responses. … WebPlasma B cells produce the same antibody as the parent B cell, but they aren’t membrane bound. Instead, plasma B cells can secrete antibodies. Secreted antibodies work to identify free pathogens that are circulating throughout the body. When the naive B cell divides and differentiates, both plasma cells and memory B cells are made.

WebFeb 16, 2011 · Plasma cells make and release antibodies that connect to the same antigen as the original B-cell receptor. Plasma cells make thousands of antibodies per second, which spread throughout your body, trapping any viruses they see along the way. What do antibodies do? Antibodies trap invading viruses or bacteria in large clumps. WebDestroying the membrane of foreign cells or pathogens weakens their ability to proliferate, and helps to stop the spread of infection. Agglutination: Agglutination uses antibodies to cluster and bind pathogens together, much like a cowboy rounds up his cattle. pops of colour
