| Popis: | SummaryThis is the first demonstration that pepstatin levels following i.p. injection may be reached which are totally inhibitory to cathepsin D contained in the lung. Thus an animal model has been created, which is devoid of cathepsin D as demonstrated by measurement of an extract of the lung. When this model was challenged with the pulmonary Arthus reaction no inhibition of the Arthus reaction was observed. We conclude that cathepsin D is not the primary direct mediator of the pulmonary Arthus reaction.The authors are grateful for the helpful assistance of Drs. P. A. Ward and H.
