title: Reduction in CD1 positive epidermal Langerhans cell numbers in leprosy lesions following epicutaneous application of 2:4 dinitrochlorobenzene.
abstract: A study was made on Langerhans cells (LC) in the dermal lesions of leprosy after epicutaneous application of 2:4 dinitrochlorobenzene (DNCB) to the lesion. LC were quantitated with OKT6 monoclonal antibody and indirect immunofluorescence. A depletion or reduction in the numbers of CD1+ epidermal LC was observed at both 4 and 24 hours after the application of DNCB in the lesions of both tuberculoid and lepromatous leprosy, compared to untreated lesions.
