Rapid Pace of Scientific Progress
The coming together actually underscored the incredible standard of scientific progress on feeding, trunk weight together with metabolism, together with the key role the encephalon plays inwards these processes. This is largely due to remarkable technical breakthroughs existence applied yesteryear people who know how to utilisation them to answer of import questions. Conditional knockout together with transgenic mice, inwards which genes tin last manipulated inwards specific jail cellphone types, travel on to play an of import role inwards neuroscience research. However, the to a greater extent than recent introduction of optogenetic together with DREADD technology has been a quantum leap. Optogenetics (light-activated ion channels) allows researchers to manipulate specific neuron populations using light, which offers exquisite spatial together with temporal control. This is of import because 1) yous tin burn downwardly (or inhibit) neurons inwards a means that roughly approximates how they would burn downwardly naturally, together with 2) fifty-fifty inside tiny sub-nuclei of your brain, at that spot tin last a number of dissimilar jail cellphone types performing dissimilar functions, so having a technique amongst jail cellphone type specificity is useful (in contrast, imagine trying to create upward one's hear the percentage of a nucleus yesteryear lesioning it, which mightiness destroy 10 dissimilar intermingled jail cellphone populations all doing dissimilar things). One early on representative of the application of optogenetics to feeding showed that activating AgRP neurons inwards the arcuate nucleus "evokes voracious feeding inside minutes" (1). AgRP neurons were already known to last an of import neuron population for hunger together with feeding, but this experiment demonstrated it inwards the most convincing vogue to date.
DREADD channels are used to activate or inhibit neuron activity using injections of the synthetic ligand CNO. This is a overnice technique because it's non-invasive (as opposed to optogenetics). DREADD technology has bolstered the finding that activating AgRP neurons drives feeding together with rapid fatty gain (2).
There are a number of other interesting emerging technologies, but those 2 stand upward out.
Palmiter Lab
Richard Palmiter (University of Washington) gave the opening keynote address, describing his inquiry on a feeding circuit from AgRP neurons inwards the arcuate nucleus to the parabrachial nucleus together with and so the key nucleus of the amygdala. This circuit seems to near off nutrient intake inwards response to aversive stimuli (sickness, pain, fear), but may non play much of a role inwards feeding nether normal circumstances.
physician Palmiter likewise presented the remarkable finding that ablating AgRP neurons reverses the obesity together with infertility phenotype of ob/ob (leptin-deficient together with genetically obese) mice.
As the inventor of the transgenic mouse, physician Palmiter has played a major role inwards advancing scientific progress inwards the biological sciences.
Ozcan Lab
Umut Ozcan (Harvard University) presented information from his lab suggesting that leptin resistance inwards the hypothalamus is caused yesteryear endoplasmic reticulum stress (ER stress; a flat of cellular stress that tin last caused yesteryear misfolded proteins). He has applied a chemical compound (SR-01) inwards obese mice that reduces ER stress, restores leptin sensitivity together with causes remarkable fatty loss. This chemical compound has no upshot inwards genetically obese mice that lack leptin receptors, together with it has no upshot on lean mice, both of which back upward his hypothesis that it specifically increases leptin sensitivity inwards diet-induced obese mice. He has been presenting these information at meetings for going on 2 years together with they haven't been published yet, which I regain puzzling. But they surely practice await promising.
Lam Lab
Tony Lam (University of Toronto) presented his information on the role of glucagon inwards blood glucose command via the brain. Glucagon is an of import instrumentalist inwards blood glucose command via the liver, but its effects were by together with large assumed to resultant from straight actions on the liver until physician Lam's findings. He showed that glucagon likewise acts inwards the encephalon to regulate blood glucose, but inwards the opposite direction to its actions inwards the liver (suppresses blood glucose), together with that diet-induced obese animals lose the powerfulness to activate this mechanism, potentially contributing to elevated blood glucose inwards obesity.
Lowell Lab
Brad Lowell gave a remarkable talk. His lab is focused on agreement how AgRP together with POMC neurons are regulated yesteryear other neurons. As stated above, this small-scale population of neurons inwards the arcuate nucleus is the most strong feeding circuit known inwards the brain. POMC neurons are a well-characterized neuron population inwards the arcuate nucleus that suppress feeding. The Lowell lab uses a combination of neuron tracing techniques (tracing the brain's wiring diagrams), optogenetics, together with electrophysiology (measuring the 'electrical' activity of neurons), to non bad effect.
I won't travel through the entire talk, which was incredibly information-dense, but I volition nurture 2 key findings:
Sternson Lab
Scott Sternson (NIH's prestigious Janelia farm campus) is interested inwards the downstream targets of AgRP neurons, together with he likewise makes extensive utilisation of optogenetics, DREADDs together with related approaches. Dr. Sternson argued for a prototype shift inwards agreement feeding-related motivation. Activating AgRP neurons increases motivation for food, in all probability reflecting hunger. But what is hunger, together with how does it shape hereafter nutrient alternative behaviors (via vantage processes)? He presented information suggesting that hunger drives nutrient intake behaviour together with learning through a procedure involving negative reinforcement.
He showed that activating AgRP neurons inwards mice (presumably inducing a hunger-like state) is aversive (unpleasant). Also, experimentally suppressing the activation of AgRP neurons caused yesteryear hunger is reinforcing/rewarding (increases the likelihood of seeking situations/flavors associated amongst the cessation of AgRP neuron activity), basically suggesting that the satiety nation is reinforcing because it relieves the unpleasant nation of hunger. So animals acquire to prefer situations associated amongst the relieving of the aversive 'hunger' state, together with this is percentage of how the vantage organization learns how to guide food-seeking behavior
Zeltser Lab
Lori Zeltser (Columbia University) had a fascinating speak on anorexia that likewise contained a really interesting tibit on insulin together with obesity. I won't acquire into all the details of her talk, but she is researching the intersection betwixt genes, calorie restriction, together with psychological stress inwards promoting anorexia.
The Val66Met allele of the BDNF factor is strongly associated amongst anorexia inwards at to the lowest degree some human studies. BDNF is percentage of the leptin signaling pathway together with hence plays an of import role inwards the command of nutrient intake together with trunk fatness. BDNF Val66Met mice are relatively normal, but when stressed (by social isolation) or temporarily calorie-restricted, mice volition travel through spontaneous periods of aphagia (no eating). I regain it remarkable that it's possible to model anorexia inwards mice, but her information were fairly convincing that this human genetic susceptibility constituent increases the adventure of anorexia nether weather condition of psychological or metabolic stress. We don't know if the same is truthful inwards humans, but it seems plausible based on her data.
She presented some other interesting tidbit that's relevant to the insulin-obesity idea: mice amongst a hypothalamus-specific deletion (Nkx2.1) of the insulin receptor withdraw hold normal trunk weight, trunk fatness, together with leptin levels. The implication is that (complete) insulin resistance inwards the hypothalamus does non Pb to leptin resistance or obesity, which bears on i of the to a greater extent than pop versions of the insulin-obesity hypothesis (e.g., the thought that hyperinsulinemia causes hypothalamic insulin resistance, which causes hypothalamic leptin resistance, which leads to obesity).
Cowley Lab
Michael Cowley (Monash University) gave i of the most fascinating talks, partially because I wasn't aware of this trouble of investigation prior to the conference. In short, he has shown that elevated leptin is largely responsible for obesity-induced hypertension (high blood pressure) inwards rodents, together with the show suggests the same is truthful for humans, who likewise tend to educate hypertension amongst obesity. He (with Stephanie Simonds) lately wrote an first-class review article inwards Trends inwards Neurosciences that covers most of the show (3). The illustrations of the sympathetic (SNS) together with parasympathetic (PNS) nervous systems, together with the encephalon regions involved inwards SNS together with PNS outpouring are actually outstanding inwards that paper. I'll last hanging on to it every bit a reference.
The encephalon controls the SNS together with PNS, which regulates many 'autonomic' (unconscious) functions similar view rate, lipolysis, glucose control, adrenaline release, estrus production, digestion, together with blood pressure. Normally, it does so inwards response to leptin together with other peripheral signals. During the evolution of obesity, the encephalon becomes resistant to many of leptin's actions, such every bit its powerfulness to suppress nutrient intake together with cut trunk fatness. However, it doesn't travel resistant to leptin's powerfulness to stimulate the SNS, so the SNS goes into overdrive inwards obese rodents together with humans. Dr. Cowley's information propose that this is due inwards large percentage to increased leptin acting inwards the dorsomedial hypothalamus.
Insulin likewise activates the SNS, together with obesity is likewise associated amongst elevated insulin. Elevated insulin acting on the encephalon is likewise in all probability a constituent that contributes to hypertension through similar pathways. Interestingly, low-carbohydrate diets oftentimes withdraw hold a dramatic upshot to apace cut blood pressure. Dr. Cowley's results propose that this is in all probability due to a reduction of insulin activity inwards the brain.
Tschop Lab
Matthias Tschop (Institute of Diabetes together with Obesity Research, Munich) was i of the organizers of the conference. He runs a mega-lab inwards Deutschland together with is the manager of a inquiry institute. We withdraw hold collaborated amongst him on agreement the role of hypothalamic inflammatory signaling inwards obesity. The most interesting percentage of his speak was his description of obesity drugs he has created yesteryear fusing gastrointestinal satiety hormones (including glucagon, GLP-1 together with PYY) to i some other inwards a unmarried molecule. He is basically trying to create a drug that mimics the hormonal effects of gastric bypass, so that people tin acquire the same weight loss together with glucose command benefits without surgery. His results inwards rodents are impressive, together with at that spot are some preliminary information suggesting a similar upshot inwards humans.
Schwartz Lab
Mike Schwartz (my electrical flow mentor; University of Washington) gave a non bad closing keynote address. He argued for a novel framework for thinking virtually blood glucose regulation.
Researchers withdraw hold long known that at that spot are apparently 2 ways that blood glucose is regulated next a meal: 1) insulin increases tissue glucose uptake together with reduces glucose production yesteryear the liver, together with 2) some other unknown machinery of glucose disposal that does non rely on insulin. The latter is referred to every bit 'glucose effectiveness' together with accounts for 50% of the body's powerfulness to regulate blood glucose next a meal! Originally, glucose effectiveness was thought to last a passive, unregulated process.
One of the most interesting recent discoveries inwards diabetes inquiry is that nether sure conditions, the encephalon tin completely regulate blood glucose without whatever aid from insulin. This has been shown multiple times inwards type 1 diabetic rats that completely lack insulin. Infusing leptin into the encephalon of these animals almost completely normalizes their blood glucose control, both yesteryear reducing liver glucose production together with increasing tissue glucose uptake. My colleague Greg Morton has done a lot of the piece of job on this. This suggests that the encephalon tin withdraw hold a major influence on blood glucose control, together with that this organization is in all probability partially redundant amongst the insulin organization of blood glucose rule (which is evidently really of import nether normal circumstances).
physician Schwartz presented information suggesting that glucose effectiveness may inwards fact last a regulated (not passive) procedure that results at to the lowest degree inwards percentage from gastrointestinal signals acting on the brain, together with that it is impaired inwards obesity. This has huge implications for diabetes treatment, because if nosotros tin figure out how this procedure works, it may pave the means for diabetes treatments that don't rely on insulin at all! Most electrical flow drug treatments rely on insulin, insulin sensitizers, and/or insulin secretogogues. Insulin therapy tin withdraw hold serious unwanted side effects such every bit hypoglycemia.
My Poster
I presented a poster on our finding that when rats are fed a fattening diet, they sense a rapid increment of activated caspase-3 inwards astrocytes of the arcuate nucleus together with other encephalon regions (within iii days). Although rats gained fatty apace on this diet, fatty gain did non seem to explicate the effect. Caspase-3 is unremarkably associated amongst a type of jail cellphone expiry called apoptosis, notwithstanding inwards this instance at that spot was no apoptosis to last found. We recall that caspase-3 is percentage of the rapid cellular injury response to this diet that nosotros reported previously (4). This suggests a novel non-apoptotic role for caspase-3 inwards the brain's response to injury, together with suggests that astrocytes may last trying to comprise impairment to of import feeding centers early on during exposure to a fattening diet. The poster was good received. These information were accepted for publication inwards the journal Brain Research 2 weeks ago.
Conclusion
The conference was first-class together with left my hear extremely full. There were many informative talks together with posters that I left out of this summary. The standard of scientific regain correct similar a shot is mind-boggling; it would last a full-time task simply to maintain upward amongst electrical flow findings inwards my plain alone. I'm confident that this novel inquiry volition pay dividends inwards agreement together with improving human health, together with specially preventing together with treating obesity together with diabetes. In the meantime, nosotros already know how to preclude (and to a lesser extent, treat) most obesity together with diabetes using diet together with lifestyle.

Tips Today Neuronal Command Of Appetite, Metabolism As Well As Weight
Last week, I attended a Keystone conference, "Neuronal Control of Appetite, Metabolism together with Weight", inwards Banff. Keystone conferences are small, focused meetings that tend to attract high character science. This special conference centered or so my ain professional person inquiry interests, together with it was incredibly informative. This postal service is a summary of some of the most salient points.Rapid Pace of Scientific Progress

I won't travel through the entire talk, which was incredibly information-dense, but I volition nurture 2 key findings:
- What neurons activate AgRP neurons together with crusade hunger together with feeding? PACAP together with TRH eurons inwards the paraventricular nucleus ship excitatory projections to AgRP neurons, together with stimulating these neurons greatly increases feeding. The DMH likewise sends excitatory projections to AgRP neurons, but these are weaker.
- The arcuate nucleus mediates a large percentage of leptin activity on appetite together with trunk weight, yet deleting leptin receptors from arcuate neurons doesn't crusade much obesity, implying that they are receiving leptin-responsive signals from upstream neurons. What are these neurons? Dr. Lowell showed that leptin receptor expressing neurons inwards the dorsomedial hypothalamus ship dense inhibitory projections to AgRP neurons. Activating these DMH neurons potently suppresses feeding.
Sternson Lab
Scott Sternson (NIH's prestigious Janelia farm campus) is interested inwards the downstream targets of AgRP neurons, together with he likewise makes extensive utilisation of optogenetics, DREADDs together with related approaches. Dr. Sternson argued for a prototype shift inwards agreement feeding-related motivation. Activating AgRP neurons increases motivation for food, in all probability reflecting hunger.

Also, experimentally suppressing the activation of AgRP neurons caused yesteryear hunger is reinforcing/rewarding (increases the likelihood of seeking situations/flavors associated amongst the cessation of AgRP neuron activity), basically suggesting that the satiety nation is reinforcing because it relieves the unpleasant nation of hunger. So animals acquire to prefer situations associated amongst the relieving of the aversive 'hunger' state, together with this is percentage of how the vantage organization learns how to guide food-seeking behavior
