Increased neurogenesis in canon imageclass mf227dw feeding centers of the murine hypothalamus is associated with weight loss in diet-induced obese rodents (Kokoeva et al., 2005 and Matrisciano et al., 2010), but this relationship has not been examined in other species.

Postmortem hippocampal neurogenesis rates and premortem metabolic parameters were statistically analyzed in 8 chow-fed colony-reared adult bonnet macaques.Dentate gyrus neurogenesis, reflected by the immature neuronal marker, doublecortin whole wheat phyllo dough (DCX), and expression of the antiapoptotic gene factor, B-cell lymphoma 2 (BCL-2), but not the precursor proliferation mitotic marker, Ki67, was inversely correlated with body weight and crown-rump length.DCX and BCL-2 each correlated positively with blood glucose level and lipid ratio (total cholesterol/high-density lipoprotein).

This study demonstrates that markers of dentate gyrus neuroplasticity correlate with metabolic parameters in primates.
