interleukin (IL)

Interleukins (ILs) are a group of signaling proteins produced mainly by immune cells to facilitate communication and coordinate immune responses. They help regulate the growth, differentiation, and activity of white blood cells, vital for defending the body against infections and managing inflammation. Think of interleukins as messengers that coordinate the immune system’s efforts, ensuring cells work together efficiently to fight off pathogens and heal tissues. Different interleukins have specific roles, influencing processes such as inflammation, immune activation, and cell repair, making them essential for maintaining immune health and response.
