K1 Lateral PBN K1 Hindbrain K1 Energy balance K1 Cold exposure K1 Obesity K1 Thyroid K1 Brown adipose tissue K1 Diet-induced obesity K1 Sex differences K1 PVN AB Chronic low-grade inflammation and increasedserum levels of the cytokine IL-6 accompany obesity.For brain-produced IL-6, the mechanisms by which itcontrols energy balance and its role in obesityremain unclear. Here, we show that brain-producedIL-6 is decreased in obese mice and rats in a neuroanatomically and sex-specific manner. Reduced IL-6mRNA localized to lateral parabrachial nucleus(lPBN) astrocytes, microglia, and neurons, includingparaventricular hypothalamus-innervating lPBN neurons. IL-6 microinjection into lPBN reduced foodintake and increased brown adipose tissue (BAT)thermogenesis in male lean and obese rats byincreasing thyroid and sympathetic outflow to BAT.Parabrachial IL-6 interacted with leptin to reducefeeding. siRNA-mediated reduction of lPBN IL-6leads to increased weight gain and adiposity,reduced BAT thermogenesis, and increased foodintake. Ambient cold exposure partly normalizesthe obesity-induced suppression of lPBN IL-6. Theseresults indicate that lPBN-produced IL-6 regulatesfeeding and metabolism and pinpoints (patho)physiological contexts interacting with lPBN IL-6 PB Cell Press SN 2211-1247 YR 2019 FD 2019 LK http://hdl.handle.net/10347/21799 UL http://hdl.handle.net/10347/21799 LA eng NO Mishra et al.
