Endocannabinoids1.2.1.Endocannabinoids are a big group of ester, ether, and amide derivatives of fatty Endocannabinoids acids, of which the best-known mediators of cellular metabolism are derivatives of fatty Endocannabinoids are a big group of ester, ether, and amide anandamide (AEA) and 2-arachidonoylbest-known mediators of cellular metabolism are anandamide (AEA) acids, of which the glycerol (2-AG) [76,77]. Endocannabinoids are mainly biosynthesized from phospholipids present within the cell membrane. AEA synthesis begins when arachidonic acid is transferred from phosphatidylcholine to phosphatidylethanolamine, so thusformed N-arachidonoyl phosphatidylethanolamine is then hydrolyzed to AEA by phospholipase A2, C, or D [79]. However, the synthesis of 2-AG is catalyzed by diacylglycerol lipase, which hydrolyzes phosphatidylinositol [80]. On account of biological properties similar toInt. J. Mol. Sci. 2021, 22,ten ofand 2-arachidonoyl glycerol (2-AG) [76,77]. Endocannabinoids are primarily biosynthesized from phospholipids present in the cell membrane. AEA synthesis starts when arachidonic acid is transferred from phosphatidylcholine to phosphatidylethanolamine, so thus-formed N-arachidonoyl phosphatidylethanolamine is then hydrolyzed to AEA by phospholipase A2 , C, or D [79]. Nevertheless, the synthesis of 2-AG is catalyzed by diacylglycerol lipase, which hydrolyzes phosphatidylinositol [80]. Because of biological properties related to endocannabinoids (KDM4 Inhibitor Accession activation from the identical receptors), phytocannabinoids had been found, of which cannabidiol and tetrahydrocannabinol will be the best recognized for their effects on cellular metabolism [813]. Apart from other functions that involve regulation of leukocyte metabolism, endocannabinoids fulfill their metabolic part in the body primarily through the activation of G protein-coupled receptors. Amongst them, the most crucial would be the cannabinoid receptors (CB1 and CB2), which have opposing effects relative to every single other [76,77]. Activation of CB1 has pro-oxidative and pro-inflammatory effects, though CB2 activation enhances antioxidant and anti-inflammatory circumstances [76,77]. For the reason that CB2 is abundant in immune cells, endocannabinoids are considered to be the main regulators of inflammation, so the improved activation of cannabinoid receptors in autoimmune ailments is quite generally viewed as a protective mechanism [84]. That is supported by the fact that mutations within the CB2 receptor may possibly lead to greater lymphocyte activity. Different mutations, which includes the nonsense mutations in enzymes that synthesize endocannabinoids, correlate using a larger threat of some autoimmune diseases [85,86]. Furthermore, other receptors like peroxisomeproliferator-activated receptors (PPARs), particularly PPAR- and PPAR-, ar.
