PR-39, a porcine host defence peptide, is prominent in mucosa and lymphatic tissue of the respiratory tract in healthy pigs and pigs infected with actinobacillus pleuropneumoniae

Abstract

These immunohistochemical findings indicate that, in addition to polymorphonuclear neutrophils, other cells are involved in the expression, storage, or uptake of PR-39. The presence of PR-39 in healthy lung tissue showed that this antibacterial peptide might be important for the maintenance of health.
