Mechanisms that may underlie the antiobesity effects of Leptin

Posted on July 13, 2011 by weightcontrol

Scientists have known for some time that the hormone leptin acts in the brain to prevent obesity, but the specific underlying neurocircuitry has remained a mystery. Now, new research published by Cell Press in the July 14 issue of the … Continue reading →

Posted in Leptin | Tagged " concludes Dr. Lowell. "As POMC neurons prevent obesity, " explains senior study author Dr. Bradford B. Lowell from Beth Israel Deaconess Medical Center and Harvard Medical School. "However, " says Dr. Linh Vong, a first author on the study. Importantly, a reduction in leptin levels, at least in part, but the specific underlying neurocircuitry has remained a mystery. Now, despite intensive investigation, direct action of leptin on POMC neurons has not been shown to play a large role in controlling body weight. This suggests that there are likely to be other leptin-responsive neurons that are critical , Dr. Lowell and colleagues took a new approach for identifying these "unidentified" body weight-regulating neurons and investigated whether leptin's effects are mediated primarily by excitatory (glutam, in part due to incomplete knowledge regarding leptin-responsive neurons." Previous studies by Dr. Lowell's group and others pinpointed a region of the brain called the arcuate nucleus as the site of k, in response to leptin, increases the activity of these GABA neurons. Taken together, indirect regulation of POMC neurons by leptin reconciles the known important role of POMC neurons in regulating body weight with the relatively unimportant role played by direct action of leptin on PO, Leptin, leptin's antiobesity effects. Further, new research published by Cell Press in the July 14 issue of the journal Neuron reveals neurobiological mechanisms that may underlie the antiobesity effects of leptin. "Leptin is a hormone that is sec, pro-opiomelanocortin (POMC) neurons, reside in this region. Although many POMC neurons express receptors for leptin, Scientists have known for some time that the hormone leptin acts in the brain to prevent obesity, such as occurs with fasting, the findings suggest that modulation of GABA output is a key aspect of leptin action. "Leptin working directly on GABA neurons reduces inhibitory tone to POMC neurons, the GABA neurons are "upstream" of the POMC neurons and, the GABA neurons are less active. Conversely, the underlying mechanisms responsible for this are poorly understood, their disinhibition by leptin action on upstream GABA neurons likely mediates, we found that leptin's antiobesity effects are mediated predominantly by GABA neurons and that glutamate neurons play only a small role, which have been shown to play a key role in appetite suppression | Leave a comment
