    GlossaryInnate Immune Cells

    cells that provide immediate, non-specific defense against pathogens

    Innate immune cells are a type of immune cell that form the body's first line of defense against infections. These cells, which include macrophages, neutrophils, and natural killer (NK) cells, respond quickly to pathogens in a non-specific manner, meaning they attack any foreign invader without needing prior exposure. They are crucial for immediate defense and also help to activate the adaptive immune system for a more targeted response.
