Mouse macrophage elastase, a metalloproteinase secreted by inflammatory macrophages, catalyzed the limited proteolysis of selected subclasses of mouse immunoglobulins, including monomeric IgG2a, IgG3, and some forms of IgG2b. Mouse IgG1 was resistant to elastase degradation; however, human IgG1 was degraded. IgG3 in immune complexes was cleaved in a manner(More)
Inflammatory mouse peritoneal macrophages secrete a metalloproteinase that is not inhibited by alpha 1-proteinase inhibitor. This proteinase, macrophage elastase, recognizes alpha 1-proteinase inhibitor with macrophage elastase does not involve a stable proteinase-inhibitor complex and results in the proteolytic removal of a peptide of apparent molecular(More)
