B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies.
There's a lot we don't currently know about lymphoid (ED3) Macrophages but it's relatively safe to assume that they do not have any major role in secreting antibodies. Macrophages tend to engulf and enzymatically destroy foreign objects in the body, this is their major purpose, if that object is coated in antibodies they're better at destroying it but they do not produce those antibodies themselves. The only real way that macrophages affect antibody production is that after destruction of intruder they'll present elements of the intruder to another variety of immune cell which will then go on to produce antibodies, it's also possible that they will produce interleukins or other compounds to upregulate antibody production but again: macrophages are not known to produce antibodies.
produce antibodies Plasma cells are antibody-manufacturing cells derived from B lymphocytes, following their activation by an antigen. They are responsible for humoral immunity - immunity conferred by antibodies present in the blood plasma. Plasma cells are capable of synthesising and secreting antibodies at a rate of 2000 molecules per second. Each cell will only synthesise and secrete one type of antibody. This antibody will bind specifically to the antigen that initially activated the precursor B lymphocyte. Plasma cells will synthesise and secrete antibody molecules over their short life span of 4 to 5 days. The secreted antibodies circulate in the blood or lymph and bind to their complementary antigen, thus marking them for destruction by other mechanisms.
Yes, white blood cells, specifically B cells, produce antibodies in response to antigens present on injected microorganisms. When these antigens are recognized, B cells are activated and differentiate into plasma cells that secrete specific antibodies designed to neutralize or mark the microorganisms for destruction. This immune response is a crucial part of the body's defense against infections.
Secrete means to produce, to give off. Clams secrete calcium to make their shells.
B cells, plasma cells, and antibodies are all part of the immune system. B cells are a type of white blood cell that produce antibodies when activated by antigens. Plasma cells are a mature form of B cells that secrete large amounts of antibodies. Antibodies are proteins produced by B cells that help to neutralize pathogens and foreign substances in the body.
