TR2 is a type of protein that plays a crucial role in the immune system. It is part of the Toll-like receptor family, which helps the body recognize and respond to pathogens like bacteria and viruses. TR2 is involved in signaling pathways that activate immune responses, making it essential for defending against infections. Research on TR2 has implications for understanding various diseases, including autoimmune disorders and cancer. By studying how TR2 functions, scientists hope to develop new therapies that can enhance immune responses or modulate them in cases where the immune system is overactive, potentially leading to better treatment options for patients.
