Innate Lymphoid Cells (ILCs) are a type of immune cell that play a crucial role in the body's defense against infections and maintaining tissue health. Unlike other immune cells, ILCs do not have specific receptors for pathogens, but they respond quickly to signals from the body. They are found in various tissues, including the gut, lungs, and skin, where they help regulate inflammation and support other immune responses. There are three main groups of ILCs, known as ILC1, ILC2, and ILC3, each with distinct functions. For example, ILC1 cells are important for fighting viral infections, while ILC2 cells help combat allergies and ILC3 cells are involved in protecting against bacterial infections. Together
