What is a B cell and definition of a B cell

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.
