Basophils
Basophils are a type of white blood cell that play a crucial role in the immune system. They are responsible for protecting the body against bacterial and parasitic infections, as well as playing a role in allergic reactions. When an allergen enters the body, basophils release histamine, a chemical that causes inflammation and swelling in the affected area. This response is designed to help remove the allergen from the body, but can also cause uncomfortable symptoms such as itching and redness. In addition to their role in allergic reactions, basophils also help to stimulate the immune response by releasing cytokines, which are chemical messengers that help to activate other immune cells. Overall, basophils play an important role in protecting the body against harmful invaders and maintaining a healthy immune system.
