Human keratinocytes are able to synthesize and express cell surface moieties characteristic of effector and/or accessory cells of the immune system (CD16, CD36, HLA-DR, intercellular adhesion molecule-1). In the present study, skin biopsies from healthy volunteers, from patients with psoriasis vulgaris (PV), mycosis fungoides (MF), purpura pigmentosa chronica (PPC), acute urticaria (AU) and from positive tuberculin skin tests were investigated with regard to the reactivity with the monoclonal antibodies to complement receptors CR1 CR2 and CR3 by means of a multistep immunoperoxidase method. In the clinically involved skin of all patients with PV, MF or PPC, and in biopsies obtained from positive tuberculin tests, specific epidermal intercellular staining with OKB7 and Leu anti-CR2 was seen on subcorneal keratinocytes. This finding suggests a differentiation-linked expression of CR2 on human keratinocytes in cytokine-mediated skin diseases whereas CR1 and CR3 are apparently not expressed.
