In this study we evaluated the effects of the CB1/CB2 cannabinoid receptor agonist CP55, 940 (CP) on antigen-induced asthma-like reaction in sensitized guinea pigs and we tested the ability of the specific CB2 receptor antagonist SR144528 (SR) and CB1 receptor antagonist AM251 (AM) to interfere with the effects of CP. Ovalbumin-sensitized guinea pigs placed in a respiratory chamber were challen...
Arachidonylethanolamide (AEA), the putative endogenous ligand of the cannabinoid receptor, has been shown to be a substrate for lipoxygenase enzymes in vitro. One goal of this study was to determine whether lipoxygenase-rich cells metabolize AEA. [14C]AEA was converted by human polymorphonuclear leukocytes (PMNs) to two major metabolites that comigrated with synthetic 12(S)- and 15(S)-hydroxy-a...
Cerebral malaria is a severe and often fatal complication of Plasmodium falciparum infection. It is characterized by parasite sequestration, a breakdown of the blood-brain barrier, and a strong inflammation in the brain. We investigated the role of the cannabinoid receptor 2 (CB2), an important modulator of neuroinflammatory responses, in experimental cerebral malaria (ECM). Strikingly, mice wi...
OBJECTIVE This is the first study to analyze the impact of the rs35761398 variant of the CNR2 gene leading to the substitution of GLN (Q) of codon 63 of the cannabinoid receptor 2 (CB2) with ARG (R) on the clinical presentation of chronic hepatitis in HIV/HCV coinfected patients. METHODS Enrolled in this study were 166 consecutive HIV/HCV coinfected patients, naïve for HCV treatment. A pathol...
Cannabinoids have been reported to be involved in affecting various biological functions through binding with cannabinoid receptors type 1 (CB1) and 2 (CB2). The present study was designed to investigate whether swallowing, an essential component of feeding behavior, is modulated after the administration of cannabinoid. The swallowing reflex evoked by the repetitive electrical stimulation of th...
Cannabinoid modulation of immune responses is a pathological consequence of marijuana abuse and a potential outcome of therapeutic application of the drug. Moreover, endogenous cannabinoids are physiological immune regulators. In the present report, we describe alterations in gene transcription that occur after cannabinoid exposure in a mast cell line, RBL2H3. Cannabinoid exposure causes marked...
Cannabinoids, the active components of Cannabis sativa Linnaeus (marijuana) and their derivatives have received renewed interest in recent years due to their diverse pharmacologic activities such as cell growth inhibition, anti-inflammatory effects and tumor regression. Here we show that expression levels of both cannabinoid receptors, CB1 and CB2, are significantly higher in CA-human papilloma...
گیرنده های کانابینوئیدی (cb1 و cb2 )، اندوکانابینوئید ها و لیگاندهای درون زاد شامل آناندماید (آراشیدونیل اتانول آمین ) و 2ag (2- آراشیدونیل گلیسرول) می باشند و مکانیسم های در ارتباط با متابولیسم و سنتز آنها، سیستم اندوکانابینوئید را تشکیل می دهد. گیرنده های cb1 و اندوکانابینوئیدها در ساختارهای مغزی کنترل کننده تعادل انرژی و سلولهای محیطی (هپاتوسیت ها، آدیپوسیت ها، سلول های جزایر لانگرهانس) تنظی...
Cannabinoids are promising therapies to support neurogenesis and decelerate disease progression in neuroinflammatory and degenerative disorders. Whether neuroprotective effects of cannabinoids are sustainable during persistent viral infection of the CNS is not known. Using a rodent model of chronic viral encephalitis based on Borna Disease (BD) virus, in which 1 week treatment with the general ...
All products derived from the Cannabis sativa plant are referred to as cannabis, including two highly active cannabinoids, cannabidiol (CBD) and tetrahydrocannabinol (THC). Unlike THC, CBD is not psychoactive, which makes an appealing option for those seeking pain relief without THC's “high” or potential abuse dependence. Despite lack of FDA approval, oil gaining popularity a remedy chronic pai...
