Activation of cannabinoid receptor type 2 has been shown to have anti-fibrosis function in skin and heart. However, whether activating cannabinoid receptor type 2 inhibits pulmonary fibrosis remains elusive. Lung fibroblasts and TGF-β1 are key players in the pathogenesis of pulmonary fibrosis. In this research, we aimed to investigate the role of cannabinoid receptor type 2 in pulmonary fibrosi...
BACKGROUND Cannabinoid type 2 (CB2) receptor agonists can protect myocardium against ischemia/reperfusion (I/R) injury although the underlying mechanism remains unclear. Here we report the antiapoptotic effect of CB2 receptor agonist, JWH133, during myocardial ischemia/reperfusion injury and potential underlying mechanisms. METHODS Ischemia was performed by blocking left coronary artery of ra...
BACKGROUND AND PURPOSE The aim of this study was to explore the effects of CB(2) receptor agonist and antagonist in the regulation of anxiety-like behaviours. EXPERIMENTAL APPROACHES Effects of acute and chronic treatment with the CB(2) receptor agonist JWH133 and CB(2) receptor antagonist AM630 were evaluated in the light-dark box (LDB) and elevated plus maze (EPM) tests in Swiss ICR mice. C...
Cannabinoid CB2 receptors (CB2Rs) have been recently reported to modulate brain dopamine (DA)-related behaviors; however, the cellular mechanisms underlying these actions are unclear. Here we report that CB2Rs are expressed in ventral tegmental area (VTA) DA neurons and functionally modulate DA neuronal excitability and DA-related behavior. In situ hybridization and immunohistochemical assays d...
Activation of CB2 has been demonstrated to induce directed immune cell migration. However, the ability of CB2 to act as a chemoattractant receptor in macrophages remains largely unexplored. Using a real-time chemotaxis assay and a panel of chemically diverse and widely used CB2 agonists, we set out to examine whether CB2 modulates primary murine macrophage chemotaxis. We report that of 12 agoni...
Chronic alcohol exposure reduces endocannabinoid activity and disrupts adult neurogenesis in rodents, which results in structural and functional alterations. Cannabinoid receptor agonists promote adult neural progenitor cell (NPC) proliferation. We evaluated the protective effects of the selective CB1 receptor agonist ACEA, the selective CB2 receptor agonist JWH133 and the fatty-acid amide-hydr...
چکیده زمینه و هدف: jwh133 به عنوان آگونیست گیرنده ی کانابینوئیدی-2 شناخته شده است که واجد اثر ضد درد است. سلکوکسیب (یک مهار کننده ی اختصاصی آنزیم سیکلوکسیژناز 2) به عنوان یک داروی ضد درد، کاربرد بالینی دارد و احتمالا در مسیر سیکلوکسیژناز به همراه اثر بی دردی کانابینوئیدها دخالت می نماید. هدف از مطالعه ی حاضر بررسی اثر سلکوکسیب با دوز معمول و ناچیز بر بی دردی حاصل از jwh133 بوده است. روش بررسی: ...
Enhanced intestinal transit due to lipopolysaccharide (LPS) is reversed by cannabinoid (CB)2 receptor agonists in vivo, but the site and mechanism of action are unknown. We have tested the hypothesis that CB2 receptors are expressed in the enteric nervous system and are activated in pathophysiological conditions. Tissues from either saline- or LPS-treated (2 h; 65 microg/kg ip) rats were proces...
Paraquat, a widely used herbicide, is well known to exhibit oxidative stress and lung injury. In the present study, we investigated the possible underlying mechanisms of cannabinoid receptor-2 (CB2) activation to ameliorate the proinflammatory activity induced by PQ in rats. JWH133, a CB2 agonist, was administered by intraperitoneal injection 1 h prior to PQ exposure. After PQ exposure for 4, 8...
Background and Objective: JWH133 is known to have cannabinoid-2 (CB2) receptor agonist properties. Celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is also known to have antinociceptive properties. Endocannabinoids produce analgesia possibly through cyclooxygenase (COX) pathway. The aim of the present work was: to study the effect of celecoxib on JWH133 induced antinociception and to ...
