Cannabidiol and other cannabinoids reduce microglial activation in vitro and in vivo: relevance to Alzheimer’s disease

Microglial activation is an invariant feature of Alzheimer’s disease (AD). It is noteworthy that cannabinoids are neuroprotective by preventing β-amyloid (Aβ)-induced microglial activation both in vitro and in vivo. On…

Cannabidiol Reduces Aβ-Induced Neuroinflammation and Promotes Hippocampal Neurogenesis through PPARγ Involvement

Peroxisome proliferator-activated receptor-c (PPARc) has been reported to be involved in the etiology of pathological features of Alzheimer’s disease (AD). Cannabidiol (CBD), a Cannabis derivative devoid of psychomimetic effects, has…

Cannabinoid CB2 Receptors Regulate Central Sensitization and Pain Responses Associated with Osteoarthritis of the Knee Joint

Osteoarthritis (OA) of the joint is a prevalent disease accompanied by chronic, debilitating pain. Recent clinical evidence has demonstrated that central sensitization contributes to OA pain. An improved understanding of…

Cannabinoids as novel anti-inflammatory drugs

Cannabinoids are a group of compounds that mediate their effects through cannabinoid receptors. The discovery of Δ9 -tetrahydrocannabinol (THC) as the major psychoactive principle in marijuana, as well as the…

Evaluation of Serum Cytokines Levels and the Role of Cannabidiol Treatment in Animal Model of Asthma

Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways. Studies…

Evidence for functional CB1 cannabinoid receptor expressed in the rat thyroid

Objective: Previous reports have shown that the D9 -tetrahydrocannabinol (D9 TCH), the major psychoactive cannabinoid components of marijuana, is unable to inhibit thyroid hormonal activity. The aim of this study…

Hypothalamic POMC neurons promote cannabinoid-induced feeding

Hypothalamic pro-opiomelanocortin (POMC) neurons promote satiety. Cannabinoid receptor 1 (CB1R) is critical for the central regulation of food intake. Here we test whether CB1R-controlled feeding in sated mice is paralleled…

Marijuana, Tetrahydrocannabinol, and Pulmonary Antibacterial Defenses

Although marijuana is now consumed extensively, little is known of its biologic effects on the lung. To study this problem, the intrapulmonary inactivation of an aerosolized challenge of Staphylococcus aureus…

Mechanism for inhibitory effect of cannabidiol on microsomal testosterone oxidation in male rat liver

Effects of four cannabinoids [cannabidiol (CBD), delta 8-tetrahydrocannabinol, delta 9-tetrahydrocannabinol, and cannabinol] on hepatic microsomal oxidation of testosterone (17 beta-hydroxy-androst-4-ene-3-one) were examined in adult male rats. Only CBD (30 microM)…

Uncoupling of the endocannabinoid signalling complex in a mouse model of fragile X syndrome

Fragile X syndrome, the most commonly known genetic cause of autism, is due to loss of the fragile X mental retardation protein, which regulates signal transduction at metabotropic glutamate receptor-5…
