While leptin is a well-known regulator of body fat mass, it remains unclear how circulating leptin is sensed centrally to maintain energy homeostasis. Here we show that genetic and pharmacological ablation of adult NG2-glia (also known as oligodendrocyte precursors), but not microglia, leads to primary leptin resistance and obesity in mice. We reveal that NG2-glia contact the dendritic processes of...
NG2‐glia are known to proliferate in the adult brain, however the extent of their mitotic and regenerative capacity and particularly their adult origin is uncertain. By employing a paradigm of mitotic blockade in conjunction with genetic fate tracing we demonstrate that intracerebroventricular mitotic blocker infusion leads to wide‐spread and complete ablation of NG2‐glial cells in the hypothalamus...
