ABSTRACT: Spermatogenesis, the process of spermatozoa production, is regulated by several endocrine factors, including testosterone, follicle stimulating hormone, luteinizing hormone and estradiol 17β. For spermatogenesis to reach completion, developing germ cells must traverse the seminiferous epithelium while remaining transiently attached to Sertoli cells. If germ cell ... Continue Reading

STUDY: In vitro metabolism and metabolic effects of ajulemic acid, a synthetic cannabinoid agonist
ABSTRACT: Ajulemic acid is a synthetic analog of Δ8-THC-11-oic acid, the terminal metabolite of Δ8-THC. Unlike Δ9-THC, the psychoactive principle of Cannabis, it shows potent anti-inflammatory action and has minimal CNS cannabimimetic activity. Its in vitro metabolism by hepatocytes from rats, dogs, cynomolgus monkeys and humans was studied and the results are reported here. ... Continue Reading
STUDY: Multiple Sclerosis – Systematic Review of Pharmacological Properties of the Oligodendrocyte Lineage
ABSTRACT: Oligodendrogenesis and oligodendrocyte precursor maturation are essential processes during the course of central nervous system development, and lead to the myelination of axons. Cells of the oligodendrocyte lineage are generated in the germinal zone from migratory bipolar oligodendrocyte precursor cells (OPCs), and acquire cell surface markers as they mature and ...

STUDY: Endocannabinoids and the Heart
ABSTRACT: Endocannabinoids, such as anandamide and 2-arachidonoylglycerol, are synthesized from membrane phospholipids in the heart and other cardiovascular tissues. They activate cannabinoid CB1 and CB2 receptors, TRPV1, peroxisome proliferator-activated receptors and perhaps a novel vascular G-protein-coupled receptor. Inactivation is by cellular uptake and fatty acid ... Continue Reading
STUDY: Atypical Responsiveness of the Orphan Receptor GPR55 to Cannabinoid Ligands
ABSTRACT: The cannabinoid receptor 1 (CB1) and CB2 cannabinoid receptors, associated with drugs of abuse, may provide a means to treat pain, mood, and addiction disorders affecting widespread segments of society. Whether the orphan G-protein coupled receptor GPR55 is also a cannabinoid receptor remains unclear as a result of conflicting pharmacological studies. GPR55 has ... Continue Reading
