View source for B Cell

B cells are [[Lymphocytes|lymphocytes]] that form part of the&nbsp;[[Humoral immunity|humoral immunity]] branch of the [[Adaptive immune system|adaptive immune system]]. They work by producing the neccessary [[Antibody|antibodies]] and&nbsp;presenting antigens to the [[T-cells|T cells]] via [[Immunoglobulin|immunoglobulin]] surface receptors. B cells are produced from the [[Pluripotent precursor cells|pluripotent precursor cells]] found in the [[Bone marrow|bone marrow]].<br>

B cells are a lymphocyte are a specialist lymphocyte that can perfomr two roles in regards to humoral immunity. Typically they are produced in the bone marrow hence the name "B-cell". Some B cells when they mature can specialise as antibody producing plasma cells. these produce antibodies which can bind to antigens prsented on the surface of a pathogen creating holes in the in cell wall of the pathogen causing the cells to die. The other specialsim is memory cells that contain the antigens of previous infection; thus if there is a secondary infection and the pathogen presents the same antigens the memory cells have allowed the body to create and sotre antibodies that are complemetary to the specific antigen therefore the immune response this time is much faster<ref>Immunology 8th edition Weir and Stewart Churchill Lingstone 1997</ref>.
