Figure Legend Snippet: A. Representative whole cell current clamps traces from a glucose inhibited (GI) neuron in the ventrolateral ventromedial hypothalamus (vlVMH) in response to a glucose decrease from 2.5 to 0.1 mM glucose in the presence and absence of 1 nM bone morphogenetic protein (BMP) 8B. Top trace: This neuron depolarized and increased resistance in 0.1 mM glucose but returned to baseline before glucose was returned to 2.5 mM indicating that it belongs to the subcategory of adapting (Ad) GI neurons. Bottom trace: This depolarization and increased resistance was blocked in the presence of BMP8B. B. Representative voltage responses to a constant -20 pA hyperpolarizing current pulse in 2.5- and 0.1-mM glucose in the absence (top) and presence (bottom) of BMP8B. In the absence of BMP8B the voltage response increased in 0.1 mM glucose; however, BMP8B blocked this response. C. Bar graph of the percentage change in resistance as glucose was lowered from 2.5 to 0.1 mM glucose in the absence (con) and presence (BMP) of BMP8B. BMP8B significantly decreased the percentage change in resistance. Paired t-test. *p = 0.01. White square: AdGI neurons; black dot: sustained (s) GI neurons. D. Bar graph of the percentage of nNOS expressing cells that also express the BMP receptor BMPR1a in males and females. E. Immunohistochemical images of the VMH from males (left) and females (right) showing colocalization of neuronal nitric oxide synthase (nNOS, green) and BMPR1a (red). Dapi nuclear stain in blue. White arrows indicate cells expressing both nNOS and BMPR1a. F. Hypothetical model for the effect of BMP8B on VMH GI neurons. Glucose inhibits VMH nNOS-GI neurons by inhibiting AMPK. BMP8B also exerts it's metabolic effects by inhibiting VMH AMPK. Thus, BMP8B may regulate blood glucose in females due to increased expression of BMPR1a on nNOS expressing VMH GI neurons compared to males. * p<0.01, independent students t-test.
