For example, mifamuratide (muramyl tripeptide phosphatidylethanolamine, a synthetic NOD-2 activating molecule) is an MDP-based orphan drug that induces insulin sensitization in HFD-induced obesity in mice and exploring its GLP-1 associated mechanism is critical to deal with obesity and other metabolic disorders along with its long term immunomodulatory effects [111]. The gene discussed is INS; the disease is Obesity.
