What Is the Langerhans Cell?
A Langerhans cell is a specific kind of white blood cell. Found largely in the epidermis, the outer layer of the skin, as well as in lymph nodes, Langerhans cells are an important element of the immune system. They are classified as dendritic cells because they grow projections called dendrites as they develop. Langerhans cells work to prevent infections, and they help trigger immune reactions by interacting with T-cells. The Langerhans cell, like other forms of white blood cells, is produced in the bone marrow.
