The Langerhans Unit

The Langerhans unit refers to a specialized structure in the skin and mucous membranes, primarily composed of Langerhans cells, which are a type of immune cell. These cells play a crucial role in the body’s defense system by recognizing and capturing foreign invaders, like pathogens. They help activate other immune cells to mount a response. Essentially, Langerhans units function as part of the body’s surveillance system, ensuring that threats are detected and dealt with effectively, thus maintaining our overall health and protection against infections.
