B memory cells are a B cell sub-type that are formed within germinal centers following primary infection.
B cells are important in immune responses against intra-cellular bacterial and viral infections.
Explanation:
B memory cells are formed from B lymphocytes. They are generated in germinal centers.
B cells remain relatively stable for at least 50 years in our body.
B cells have long lifespan, other features also include high sensitivity to low antigen doses, proliferation is fast and strong. B memory cells differentiates fastly into plasma cells. High affinity antibodies are produced from these plasma cells during its secondary response.
B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.
