CAMP and colitis: A lack of the antimicrobial cathelecidin (mCRAMP in mice or LL-37 in humans), which is upregulated during ileitis or colitis dependent on the level of inflammation (Koon et al, 2011; Kubler et al, 2009; Schauber et al, 2006), leads to more severe symptoms and mucosal disruption in dextran sodium sulphate (DSS) chemically induced mouse colitis (Koon et al, 2011).
