The simultaneous presence of Langerhans cell and interdigitating cell antigenic markers on inflammatory dendritic cells.

摘要

Immunohistological studies have been performed on tissues from various dermatological conditions using two monoclonal antibodies, RFD1 and NA1/34. These reagents were used to determine whether antigen expression restricted to interdigitating cells (RFD1+) and Langerhans' cells (NA1/34+) in normal tissues might occur together on dendritic cells involved in cutaneous inflammatory reactions. The results presented demonstrate that in psoriasis, allergic contact dermatitis and atopic dermatitis a proportion of the inflammatory dendritic cells express both antigens.
