[The chemotactic effect of blister roof, blister fluid and blister floor on polymorphonuclear leucocytes in dermatitis herpetiformis Duhring (author's transl)].

The chemotactic response of polymorphonuclear leucocytes to the blister roof, the blister fluid and the floor of the bulla, the underlying papillary dermis with the basement membrnae, were studied by a modified Boyden-assay in four patients with dermatitis herpetiformis. In the same way experimental suction blisters of the peri-lesional skin were investigated. The blister roofs showed no chemotactic activity contrary to the blister fluid and especially the underlying papillary dermis which attracted polymorphonuclear leucocytes in a high degree.
