Immune cell research focuses on studying the various types of cells that make up the immune system and their functions in protecting the body against pathogens and foreign invaders. This includes understanding how immune cells recognize and respond to threats, regulate immune responses, and maintain immune tolerance. By studying immune cells, researchers aim to develop new treatments and therapies for a wide range of diseases, including cancer, autoimmune disorders, and infectious diseases. Immune cell research also plays a crucial role in understanding the mechanisms of immune system disorders and improving vaccine development strategies.
