cutaneous immune system
The cutaneous immune system refers to the immune defenses located in the skin, which act as a barrier against harmful pathogens like bacteria, viruses, and fungi. It involves skin cells that recognize invaders, immune cells that respond to threats, and signaling molecules that coordinate defense actions. This system not only protects against infections but also helps repair skin damage and maintain overall skin health. It balances responding to harmful agents while avoiding overreacting to harmless substances, preventing allergies and inflammatory conditions. Essentially, the cutaneous immune system is your body's first line of defense embedded right in your skin.
