CD4+ T helper cells

CD4+ T helper cells are a type of immune cell that play a crucial role in the body's defense against infections. They help coordinate the immune response by signaling other immune cells, like B cells and cytotoxic T cells, to attack pathogens such as viruses and bacteria. By recognizing foreign invaders, CD4+ T cells help guide the immune system to effectively eliminate threats. They are also important in the development of immunity after vaccination. A healthy population of CD4+ T helper cells is vital for maintaining a strong and balanced immune system.
