title: Polymorphonuclear leukocytes: possible mechanism of accumulation in psoriasis.
abstract: Extracts of involved and uninvolved skin from nine patients with untreated psoriasis were studied for chemotactic activity. Psoriatic plaque contains increased amounts of a complement-dependent chemotactic factor that is inhibited by diisopropyl fluorophosphate. This factor may be human skin serine proteinase.
