Th2 cells

Th2 cells are a type of immune cell that plays a key role in protecting the body from certain infections, especially parasites, and in managing allergic responses. They help coordinate the immune system by signaling other cells to produce different chemicals called antibodies, which identify and neutralize invaders. Th2 cells also influence inflammation and help regulate how the immune system responds to allergens. While essential for defense, an overactive Th2 response can contribute to allergies and asthma, making their balance crucial for overall health.
