Does recombinant human neutral endopeptidase ameliorate pancreatic elastase-induced lung injury?
Pancreatic elastase induces lung injury that is worse and prolonged in NEP (-/-) mice. Pretreatment with rhNEP ameliorates this injury. Thus, upregulation of NEP is a potential therapeutic approach for pancreatitis-associated lung injury.
This study extends the degradome of MMP9 and examines components relevant to seminal fluid physiology. PN1 is proposed to be a novel inhibitor of MMP9 activity and a block to collagen cleavage, a frequent antecedent to cancer cell invasion. The interaction of MMP9 with PN1 and other serpins may lead to a better understanding of seminal vesicle function and possible impacts on fertility, as well as provide novel therapeutic targets.
