B cells are a type of white blood cell that play a crucial role in the immune system. They produce antibodies that recognize and neutralize pathogens, providing long-term protection against future infections.
How do B cells become activated in response to an allergen?
When an allergen enters the body, it binds to B cells that have specific receptors for that allergen. This binding triggers the B cells to produce antibodies and activate other immune cells.
Can B cells become overactive and contribute to autoimmune diseases?
Yes, in some cases, B cells can produce antibodies that attack the body's own tissues and contribute to autoimmune diseases.
How do doctors test for allergies involving B cells?
Skin prick tests and blood tests can detect the presence of allergen-specific antibodies produced by B cells. These tests can help doctors identify which allergens trigger an individual's allergic reactions.
