Summary
Affected and unaffected skin from patients with vulgar psoriasis and normal skin from a control group were investigated for the presence of fibronectin with an indirect immunofluorescence technique. In the control group, fibronectin is missing in the epidermis, but is found in the basement membrane zone of the dermo-epidermal junction area, in the papillary and the reticular dermis, and in the vascular and neural systems of the skin. The same distribution is also found in unaffected psoriatic skin, whereas in affected skin a change in the distribution of fibronectin is found in the dermis and in the basement membranes, together with the presence of fibronectin in the epidermis, mainly in the cornified layers.
Zusammenfassung
Gesunde und kranke Haut von Psoriasispatienten und normale Haut von gesunden Kontrollpersonen wurden mit indirekter Immunfluorescenztechnik auf Fibronectin untersucht. In der gesunden Kontrollgruppe wurde Fibronectin in dermalen Strukturen nachgewiesen, wie in der Basalmembranzone, der papillären und retikulären Dermis, und in den vasculären und neuralen Systemen der Haut. In der Epidermis war kein Fibronectin vorhanden. Das gleiche Bild wurde auch in der nicht-erkrankten Psoriatikerhaut festgestellt. In der kranken Psoriatikerhaut liegt eine Änderung der Verteilung des Fibronectins in der Dermis vor zusammen mit dem Nachweis von Fibronectin in der Epidermis, hauptsächlich in der stratum corneum.
