Peptidylarginine Deiminases Present in the Airways During Tobacco Smoking and Inflammation can Citrullinate the Host Defense Peptide LL-37 Resulting in Altered Activities.
Bacterial colonization of the lower respiratory tract is frequently seen in COPD and may cause exacerbations leading to deterioration of the disease. An important part of the innate lung immunity is antimicrobial peptides, not least the cathelicidin hCAP-18/LL-37. Peptidylarginine deiminases (PADI) posttranslationally modifies proteins by converting cationic peptidylarginine residues to neutral pe
