Definitions
- the present invention relates to a Langerhans cell migration inhibitor, and more specifically, to a Langerhans cell migration inhibitor containing activated biminmin D as an active ingredient.
- Langerhans cells take in foreign antigens into the skin, migrate to the lymphatic vessels, become bale cells, partially degrade the antigens inside the cells, and then migrate to nearby lymphoid organs to give the T cells this antigen. , The T cells are differentiated into cells that cause contact dermatitis. It is known that Langerhans cells infiltrate into the cornea from the limbus to the central part to produce various cytokines and cause immunoreactive inflammation.
