Innate lymphoid cells

Innate lymphoid cells (ILCs) are a type of immune cell that act quickly to protect the body from infections and tissue damage. Unlike other immune cells that need prior exposure to a pathogen, ILCs respond rapidly by releasing chemical signals to alert and coordinate the immune system. They are mainly found in tissues like the gut, lung, and skin, where they help maintain barrier integrity and support tissue repair. ILCs play a crucial role in early immune responses, inflammation, and maintaining overall immune balance without targeting specific pathogens directly.
