Langerhans Cells

With regard to the role of antigen presentation ocular DC, Langerhans cells (LHC), are considered as a "key"element of the "afferent"immune process. These dendritic cells play a dominant role in processing and presentation of antigens and carry MHC-class-II antigens that are important stimulators of T and B cells. The distribution of LHC is compartmentally localized within specific regions of the ocular surface. The central cornea is normally devoid of LHC that are positive of MHC class II, but a number of stimuli may induce their immigration. However, recently it has been shown in the mouse that even the central cornea contains DC in an immature state and their potential precursors [15] that can be activated by the presence of antigens as in corneal transplantation.
