Innate Immune Response

The innate immune response is the body's first line of defense against pathogens like bacteria, viruses, and fungi. It acts quickly and non-specifically to recognize common features of invaders, such as their cell walls or genetic material. Cells like macrophages and neutrophils identify, attack, and eliminate these threats to prevent infection from spreading. This response also triggers inflammation and signals other parts of the immune system to get involved. Unlike the adaptive immune system, it doesn't remember specific pathogens but provides immediate, general protection to keep you safe.
