  • Title: Localization of porcine trappin-2 (SKALP/elafin) in trachea and large intestine by in situ hybridization and immunohistochemistry.

    Abstract:
    Trappin-2 (SKALP/elafin), an elastase inhibitor, belongs to a unique family of proteinase inhibitors that are covalently anchored at the site of action through their transglutaminase substrate domain and are collectively called trappins. The transglutaminase substrate domain is therefore called "cementoin moiety". Currently, human, porcine, and bovine trappin-2 (SKALP/elafin) have been characterized. Previously, we showed that porcine trappin-2 (SKALP/elafin) occurs mainly in the trachea and large intestine. To determine the localization of trappin-2 (SKALP/elafin) at the cellular level, we carried out in situ hybridization and immunohistochemistry using the porcine trachea and large intestine and found that trappin-2 (SKALP/elafin) is produced in the goblet cells of the tracheal epithelium and of the large intestinal crypts. These locations suggest that trappin-2 (SKALP/elafin) is secreted onto the luminal surface of the trachea and crypts of Lieberkuhn and plays a protective role against destructive bacterial proteinases.
