Lymphocytes and Langerhans cells in the normal human cornea.

The distribution of B- and T-lymphocytes, of OKIa positive cells, and of HLA-ABC antigens in the normal cornea was investigated using monoclonal antibodies. The lymphocytes and Langerhans cells are present mainly in the well-vascularized limbic region but also occur albeit in small number in the center of the cornea. HLA-ABC antigens are strongly expressed on the epithelial cells of the cornea and the limbus.
