What is the skin role in immunity?

The skin serves as a crucial barrier in the immune system, protecting the body from pathogens, toxins, and physical injuries. It acts as the first line of defense, preventing the entry of harmful microorganisms. Additionally, skin cells produce antimicrobial peptides and secrete various substances that contribute to immune responses. The skin also houses immune cells, such as Langerhans cells, which help detect and respond to potential threats.
