In addition to their well known psychotrophic effects, the cannabinoids also display immunosuppressive and anti inflammatory properties including inhibition of T and B lymphocyte proliferation and inhibition of macrophage microbiocidal acitivity. Two subtypes of cannabinoid receptors, CB1 and CB2 have been described [1,2]. While CB1, the central cannabinoid receptor, is predominantly found in t...

BACKGROUND The endocannabinoid system is involved in the pathogenesis of liver fibrosis. However, most of the findings in this area have come from experimental studies in animal models or clinical trials on chronic hepatitis C. The roles of cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2) in hepatofibrosis in patients with chronic hepatitis B (CHB) have not been studied fully. This...

Cannabinoids, as multi‑target mediators, activate cannabinoid receptors and transient receptor potential vanilloid (TRPV) channels. There is evidence to support a functional interaction of cannabinoid receptors and TRPV channels when they are coexpressed. Human conjunctiva demonstrates widespread cannabinoid receptor type 1 (CB1), CB2 and TRPV channel localization. The aim of the present study ...

BACKGROUND Implantation of a retrogradely-shed endometrium during menstruation requires an adequate blood supply. The endometrium has angiogenic potential, and endometriotic lesions grow in areas with a rich vascularization, suggesting that angiogenesis is a prerequisite for endometriosis development. Targeting vascular endothelial growth factor (VEGF) leads to an inhibition of endometriosis. D...

BACKGROUND Recent reports suggest a role for the endocannabinoid system in the pathology of nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the relationship between liver expression of cannabinoid (CB) receptor subtypes, CB1 and CB2, in morbidly obese (MO) women with different histological stages of NAFLD. METHODS We analysed hepatic CB1 and CB2 mRNA express...

Adenomyosis that is a form of endometriosis is the growth of ectopic endometrial tissue within the muscular wall of the uterus (myometrium), which may cause dysmenorrhea and infertility. Endocannabinoid mediated apoptotic mechanisms of endometriosis and adenomyosis are not known. We hypothesized that the down regulation of endocannabinoid receptors and/or alteration in their regulatory enzymes ...

Cannabinoid receptors (CB1 and CB2) and their endogenous ligands (endocannabinoids) have recently emerged as novel mediators of liver diseases. Endogenous activation of CB1 receptors promotes nonalcoholic fatty liver disease (NAFLD) and progression of liver fibrosis associated with chronic liver injury; in addition, CB1 receptors contribute to the pathogenesis of portal hypertension and cirrhot...

As a consequence of an increasingly aging population, the number of people affected by neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease and Huntington's disease, is rapidly increasing. Although the etiology of these diseases has not been completely defined, common molecular mechanisms including neuroinflammation, excitotoxicity and mitochondrial dysfunction have bee...

Sepsis is a complex condition that results from a dysregulated immune system in response to a systemic infection. Current treatments lack effectiveness in reducing the incidence and mortality associated with this disease. The endocannabinoid system offers great promise in managing sepsis pathogenesis due to its unique characteristics. The present study explored the effect of modulating the CB2 ...

Cannabinoid receptors 1 and 2 (CB1 CB2, respectively) play an important role in maintaining the integrity of blood–brain barrier (BBB). On other hand, BBB dysfunction is a common feature drug-resistant epilepsy. The focus present study was to characterize protein expression levels Gαi/o protein-induced activation by CB1 CB2 microvascular endothelial cells (MECs) isolated from brain patients wit...
