NOD2 Agonist - Synthetic muramyl tripeptide

M-TriLYS (MurNAc-Ala-D-isoGln-Lys) is a muropeptide released by Lactobacillus salivarus, after digestion of its peptidoglycan (PGN).

Chemically synthesized M-TriLYS is sensed by NOD2 and induces the activation of NF-κB [1].

However, M-TriLYS has been shown to produce the anti-inflammatory cytokine IL-10 and protect mice from colitis, unlike M-TriLYSD-ASN [1].

The opposite effect of both muropeptides may be linked to a differential transport.
