CB1 receptors are expressed all over the brain: in the prefrontal cortex, the seat of judgment and executive function; in the amygdala, which mediates the reward system; in the hippocampus, where memories are made; and even in the cerebellum.
But they are not limited to the brain. Cells in other organs, including the liver, skeletal muscle, pancreas, GI tract, and adipose tissue, upregulate their expression of CB1 in response to a high-fat diet. CB2 receptors are found primarily in immune cells. CB1 receptor stimulation returns a hyperactive cell to its normal state. If excessive amounts of a neurotransmitter are released from a neuron--either an excitatory neurotransmitter like glutamate or an inhibitory neurotransmitter like GABA—the postsynaptic cell makes endocannabinoids and sends them back across the synaptic cleft.
The ultimate result is membrane hyperpolarization and a reduction of neurotransmitter release. Hydrolases at both the presynaptic and postsynaptic sites are on hand to cleave the endocannabinoids to ensure that their effects are fleeting. Signaling through CB1 receptors. The most straightforward way to clinically interfere with the endocannabinoid system is through selective agonists or antagonists of CB1 or CB2.
Both positive and negative allosteric modulators of the receptors have also been developed. And of course there are plenty of proteins associated with CB1 and CB2 that may have regulatory functions. All of these may be appropriate targets to harness the beneficial actions of the endocannabinoid system—treatment of pain, anxiety, depression, and metabolic disorders—without eliciting the psychoactive side effects of THC.

But first, they had to show that blocking these peripheral receptors could affect appetite and addiction, behaviors that are mediated by the CNS. To do this, his lab employed a peripherally restricted CB1 inverse agonist, JD Surprisingly, they found that it reduced food intake, body weight, and insulin resistance in mice fed a high-fat diet; moreover, it did so to the same extent as its parent compound, a CB1 inverse agonist that is brain penetrant.
Both compounds also dropped the highly elevated leptin levels in these obese mice back down to normal. Leptin is made peripherally in adipose cells but acts centrally. It could thus be the very link the Kunos lab set out to find connecting peripheral CB1 receptors with CNS pathways controlling appetite. Similar results emerged from studies of a mouse model for alcoholism. This is meant to be a model for binge drinking.
In both cases, treatment with JD reduced drinking just as much as the globally acting CB1 inverse agonist. Interplay between the endocannabinoid system and the brainstem neurocircuit comprising vagovagal reflexes As with their studies with obese mice, the Kunos lab wanted to find the link between peripheral CB1 receptors and the addictive behavior mediated by the CNS.
They found it in ghrelin signaling through receptors located on vagal afferent terminals. Ghrelin is made in the stomach mucosa, which also expresses CB1 receptors and high levels of endocannabinoids. Alcohol induces endocannabinoid expression is specifically induced by alcohol in these stomach cells but not in brain or plasma cells. Ghrelin is known to promote drinking alcohol. CB1 blockade reduces alcohol consumption by preventing the acylation of ghrelin into its active form.
Paradoxically, there is evidence that THC—the original CB1 agonist, the one that makes people hungry—can reduce obesity. Kunos suggested that perhaps heavy THC use desensitizes CB1 receptors so that endocannabinoids can no longer signal through them, making THC act almost like these inverse agonists rather than a standard one.
Nichol explained that phytocannabinoids differ from endocannabinoids in several clinically significant ways. Whereas only five endocannabinoids have been isolated to date, about different chemicals have been found in Cannabis sativa. Their chemical structures are different; endocannabinoids are polyunsaturated fatty acids with a polar head group, while phytocannabinoids are terpenophenolic compounds derived from geranyl pyrophosphate.
Endocannabinoids act and are degraded locally; phytocannabinoids are metabolized in the liver, and their site of action depends on how they are ingested. Both may reduce neuronal hyperexcitability. Yet research findings on endocannabinoids are often presented out of context, especially online, and presumed to apply to cannabis as well.
Phytocannabinoids have varying binding affinities and directions of action for CB1 and CB2. THC is a partial agonist of both; CBD is an inverse agonist, albeit a weak one, of both; and others have agonistic and antagonistic effects of varying levels. They can also bind to and exert their varying effects on other receptors, like TRP channels. This diversity makes drug discovery extraordinarily challenging.
Varying effects of various phytocannabinoids. Nichol provided a few real-world examples of this challenge. Greenwich has thus proactively sponsored independent medical education to keep physicians updated on research into the endocannabinoid system, cannabis, and FDA regulations regarding cannabis use.

Or share on social media: Targeting the Endogenous Cannabinoid System to Treat Pain Many cancer patients undergoing chemotherapy have to contend with chemotherapy-induced peripheral neuropathy: numbness, tingling, and pain in their fingers and toes. It can be so severe that it limits the doses of chemotherapy they can handle, and can last for years after treatment. There are currently no effective treatments for it, but a number of preclinical studies in rodent models have suggested that drugs targeting the endocannabinoid system can reduce peripheral neuropathy induced by paclitaxel, a drug given to people with breast, lung, and ovarian cancers.
Overview of the endogenous cannabinoid system. It is expressed widely throughout the brain and periphery, in presynaptic neurons, astrocytes, microglia, and macrophages. Inhibiting MAGL increases 2-AG, decreases arachidonic acid a breakdown product of 2-AG that has proinflammatory metabolites of its own levels, and has antinociceptive and anti-inflammatory effects in many animal models of pain.
Lichtman hypothesized that MAGL inhibition might alleviate paclitaxel-induced peripheral neuropathy in mice, and he was right—it did. It required both CB1 and CB2 receptors to achieve its effects. Thankfully, the inhibitor did not induce cancer cell growth or interfere with paclitaxel when assessed in a human lung cancer cell line.
Chronic pain is different from chemotherapy-induced pain, and cannabinoids have already undergone clinical trials to treat chronic pain. But Nabiximols are not FDA-approved because they lacked efficacy in three Phase 3 clinical trials when the primary endpoint was a decrease in the numeric pain scale.
They were, however, effective on some secondary measures, like improving sleep and patient satisfaction. This could be because the Americans had visceral or bone-based cancer pain, and those in the rest of the world had more neuropathic cancer pain; or because, surprisingly, patients in the rest of the world got more opiates than the US patients. Aron H. He noted that while we tend to focus on CB1 and CB2 receptors and their ligands 2-AG and anandamide, and perhaps expand slightly outward to include the enzymes that degrade them, the lipid signaling system is much broader than that and encompasses a whole host of associated molecules.
He focuses on GPR, a nutrient-sensing G protein-coupled receptor expressed in pancreatic islets and gut enteroendocrine cells K and L cells in intestinal villi. This is true even for chronic cannabis users. So CB1 antagonists were pursued as a potential treatment for obesity, and they increased resting energy expenditure.
CB1 blockade induced weight loss and improved measures of metabolism in over 25, subjects. And yet, chronic cannabis users have lower BMIs, smaller waist circumferences a proxy for visceral fat , and are at a decreased risk of Metabolic Syndrome, insulin resistance, and Type II Diabetes than the general population—even though they consume more calories.
Chronic cannabis use may therefore have paradoxically beneficial metabolic effects. Parent Review 1y ago. Ps 19 Asher Levy. My child is in NEST program, and we are very happy with the progress. Even though his teachers are not good at communicating with parents, but I can see a positive transforming in my child. It's a small school, and seems warm and welcome. My child loves the science teacher, and I wish there were more science classes than just once a week.
The staff are not so well organized with relaxed attitude, which sometimes it's frustrating to interact with them. But once I see how my child is happy to be at the program, I have to take a step back! Parent Review 4y ago. Ps 20 Anna Silver. Absolutely revolting The principal only cares about the money she gets and steals from parents that think they are paying for their child's education.
Leave this school to save yourself from getting lied about the quality of the school. The administration doesn't care. This school USED to be amazing. Now it's sickening. Ps 34 Franklin D Roosevelt. I created lifetime friends from this school. The life lessons learned you take forever. It was located right across the street from where I live, so it was great walking to school. The school wasn't perfect but the teachers in the school did make a difference.
The only thing that was not good about this school was the substitutes, who didn't care about the students or being there to help. The classes were crowded I hope it's not like that any more. The teachers who have been there the longest are the ones who cares about the students the most. Academy - PS My daughter has attended this school for 5 years, and I couldn't be happier with my choice in elementary school. The teachers are amazing, and very dedicated to the students.
They do not teach for state tests instead they prepare the students for critical thinking. There are no text books, which I like since they create their own curriculum and are not limited to teach according to one textbook.
In Math and ELA, students are broken out in groups based on their ability across the grades, but have specific focus to help them grow and develop. The classes have two teachers and then one or two assistant teachers. They are available to answer questions.
And ClassDojo a facebook for schools is a great tool for teachers, parents, and staff to stay connected. Teachers post videos with new math concepts to help parents understand!!!! The staff is amazingly supportive. Cameron p and Ms. Friedman vp' are always there to greet parents and guide students through the day.
Alice the parent coordinator is heart of the school! It is a small school, but builds a great community and support for parents, students, teachers and staff.
Parent Review 3y ago. Ps 64 Robert Simon. It is a grade school. It has after school program that help me a lot as working parent. Parent Review 5y ago. Ps Florence Nightingale. Will not be returning next year. My son's class has 30 kids and this school overall feels incredibly overcrowded. Ps Henrietta Szold. The teachers my daughter has had at this school were great. I couldn't ask for better teachers. And the principal does an excellent job.
My experience has been a positive one at this school. My daughter has been here since kindergarten. She's now going to 4th grade. Ps Nathan Straus. PS is amazing! They truly want children to learn and will take the time to teach the kids that aren't able to learn as quick as the others.
Their staff is courteous, sympathetic and have great technics to teach children. If they had additional funding they would definitely put it to good use. My eldest graduated from this school and my little one is still there and he loves the teachers and so did my eldest. They take the time to not only teach them education; they also teach them social skills and responsibility. When asked from other parents about PS I can only think of positive things to say.
From the moment you walk in the building you are greeted and willing to help you or steer you in the direction you need. I'm happy my kids went and still go to PS My son now in High School is pleased to pick up his brother at PS as it gives him a chance to see his previous teachers and catch up with the staff.
He said he would never forget them. Parent Review 8y ago. Ps Amalia Castro. His teachers were very attentive and notified us of any issues on a daily basis. East Side Community School. It has been amazing. My child loves going to school everyday. Parent Review 2y ago. Neighborhood School.
