ABSTRACT
Objective To study the effects of TNF -?and sTNFRⅠon IL -8production and proliferatio n of psoriatic keratinocytes.Methods In vitro cultured keratinocytes were treated with TNF -?,sTNFRⅠand an-ti -TNFRⅠ.IL -8levels in supernatants were me asured by enzyme-linked immunosobent assay.Expression of IL -8mRNA in keratinocytes was observed by semiquantitive RT -PCR and Southern blotting.Proliferation index wa s measured by MTT colorimetry.Results IL -8levels,mRNA expression and pro liferation index were significantl y higher in psoriatic patients than th ose in control group(P
