What is a B cell and what does it do?
A B cell produces antibodies that bind to specific foreign substances in the body, such as bacteria or viruses.
How does a B cell help fight allergies?
B cells produce antibodies that target the allergen and trigger the release of histamine, which causes allergy symptoms.
Can B cells cause allergies?
B cells themselves do not cause allergies, but they play a key role in the immune response that leads to allergic reactions.
What is the difference between a B cell and a T cell?
B cells produce antibodies, while T cells help to destroy infected or cancerous cells.
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.
