Abstract
- For treatment of type 1 diabetes mellitus, a combination of immune-based interventions and medication to promote beta-cell survival and proliferation has been proposed. Dextromethorphan (DXM) is an N -methyl-D-aspartate receptor antagonist with a good safety profile, and to date, preclinical and clinical evidence for blood glucose-lowering and islet-cell-protective effects of DXM have only been provided for animals and individuals with type 2 diabetes mellitus. Here, we assessed the potential anti-diabetic effects of DXM in the non-obese diabetic mouse model of type 1 diabetes. More specifically, we showed that DXM treatment led to five-fold higher numbers of pancreatic islets and more than two-fold larger alpha- and beta-cell areas compared to untreated mice. Further, DXM treatment improved glucose homeostasis and reduced diabetes incidence by 50%. Our data highlight DXM as a novel candidate for adjunct treatment of preclinical or recent-onset type 1 diabetes.<br />Competing Interests: A.W., T.M., E.M. and E.L. declare the following competing financial interests: these authors are inventors of the US patent 10,464,904 entitled “Dextrorphan-derivatives with suppressed central nervous activity”; and T.M. and E.L. are inventors of the US patent 9,370,511 entitled “Morphinan-derivatives for treating diabetes and related disorders.”<br /> (The Author(s).
