WebJul 17, 2024 · B cells have special receptors that bind to one type of antigen. These cells differentiate and mature inside the spleen but are naïve. As with the T lymphocytes, B cells need to be activated. While T cells are activated by antigen-presenting cells and cytokines, B cells use their surface receptors to bind directly to an antigen. WebB cells learn to recognize the different antigens and produce specific antibodies to attack each one. The B cells respond to antigens in two ways: Primary immune response: When an antigen attaches to a receptor, your B cells are stimulated. Some B cells change into memory cells. Other B cells change into plasma cells.

Regulatory T cells suppress the actions of B and T cells to decrease the immune response when a highly active response is no longer warranted.
WebTo understand how vaccines work, it helps to first look at how the body fights illness. When germs, such as bacteria or viruses, invade the body, they attack and multiply. This invasion, called an infection, is what causes disease. The immune system uses your white blood cells to fight infection. These white blood cells consist primarily of ... WebSep 12, 2024 · How do B cells work in the immune system? B cells create antibodies. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection. B cells can also recruit other cells to help destroy an infected ...
