A role of a lymphocyte tryptase, granzyme A, in experimental ulcerative colitis

Biosci Biotechnol Biochem. 2007 Jan;71(1):234-7. doi: 10.1271/bbb.60354. Epub 2007 Jan 7.

Abstract

In the large-intestinal mucosae of rats orally administered dextran sulfate sodium, which induces an enteritis resembling ulcerative colitis (UC), the activity for granzyme A, a lymphocyte tryptase, increased at an earlier stage than that at which UC markers (growth-regulated gene product/cytokine-induced neutrophil chemoattractant-1 and caspase-3) increased. This suggests involvement of the enzyme in the exacerbation and perpetuation of enteritis.
