title: Protective effect of chlorpromazine on TNF-mediated hapten-induced irritant reaction.
abstract: Picryl chloride-induced irritant reaction (IR) was shown to be mediated by tumor necrosis factor (TNF). Anti-TNF monoclonal antibodies, but not interleukin 1 receptor antagonist (IL-1 Ra), had a protective effect. Chlorpromazine (CPZ), an inhibitor of TNF synthesis, protected against IR and inhibited the IR-associated TNF induction in ear homogenates. Investigation of the role of polymorphonuclear leukocyte (PMN) in neutropenic mice showed that neutropenia did not prevent the development of the IR.
