Antagonism of epidermal growth factor receptor tyrosine kinase ameliorates the psoriatic phenotype in organ-cultured skin.

Abstract excerpt

Psoriatic plaque skin incubated for eight days in organ culture in the presence of a potent epidermal growth factor (EGF) receptor tyrosine kinase (RTK) antagonist reverted to a more normal histological appearance, while untreated psoriatic plaque skin retained histological features associated with the psoriatic phenotype. In concomitant studies it was shown that the EGF-RTK antagonist had no significant effect...
