Abstract
Immunofluorescence (IF) studies by the direct and indirect methods demonstrate immunoglobulins and complement bound in vivo in psoriatic scales. The IF pattern is comparable to that of stratum corneum antibodies (SCAb) bound in vitro on specific substrate, as visualized by the indirect IF method. Formation of immune complexes can be responsible for the “squirting papilla” phenomenon, and conversion of the stratum corneum — which is normally an inaccessible antigen — into its reactive form seems to be brought about by proteases of polymorphonuclear leukocytes. Stimulation of protease production by polymorphonuclears appears to be an important factor in the pathogenesis of psoriasis. The stratum corneum of the epidermis is probably the target, and becomes an antigen for SCAb present in the circulation. Untersuchungen der psoriatischen Hautveränderungen mittels der direkten und indirekten Immunofluorescenzmethode zeigen in der Hornschicht Immunoglobulin- und Komplementablagerungen auf. Das IF-Muster ist dasselbe wie bei der Bindung der im normalen Serum auftretenden anti-Stratum corneum-Antikörper an dem spezifischen Substrat, d.h. normaler Hornschicht. Die Bildung von Immunkomplexen zusammengesetzt von anti-Stratum corneum-Antikörpern scheint das Phänomen der «Squirting papilla» zu verursachen, wobei das normalerweise nicht zugängliche Stratum corneum unter der Einwirkung von Traumen oder Leukocyten-Proteinasen antigenisch wird. Die Proteinase-Produktion durch angeregte polymorphonukleare Leukocyten ist vermutlich ein wichtiger pathogenetischer Faktor in Psoriasis, wobei das Stratum corneum das Target ihrer Einwirkung ist und reaktiv (antigenisch) wird, was die in vivo-Fixation der Stratum corneum-Antikörper ermöglicht.Keywords
