Megjegyzések:	Little is known of the involvement of endocannabinoids and cannabinoid receptors in skeletal muscle cell differentiation. We report that, due to changes in the expression of genes involved in its metabolism, the levels of the endocannabinoid 2-arachidonoylglycerol (2-AG) are decreased both during myotube formation in vitro from murine C2C12 myoblasts and during mouse muscle growth in vivo. The endocannabinoid, as well as the CB1 agonist arachidonoyl-2-chloroethylamide, prevent myotube formation in a manner antagonized by CB1 knockdown and by CB1 antagonists, which, per se, instead stimulate differentiation. Importantly, 2-AG also inhibits differentiation of primary human satellite cells. Muscle fascicles from CB1 knockout embryos contain more muscle fibers, and postnatal mice show muscle fibers of an increased diameter relative to wild-type littermates. Inhibition of Kv7.4 channel activity, which plays a permissive role in myogenesis and depends on phosphatidylinositol 4,5-bisphosphate (PIP2), underlies the effects of 2-AG. We find that CB1 stimulation reduces both total and Kv7.4-bound PIP2 levels in C2C12 cells and inhibits Kv7.4 currents in transfected CHO cells. We suggest that 2-AG is an endogenous repressor of myoblast differentiation via CB1-mediated inhibition of Kv7.4 channels.

Cím:	Endocannabinoid signaling at the periphery : 50 years after THC / Mauro Maccarrone, Itai Bab, Tamás Bíró, Guy A. Cabral, Sudhansu K. Dey, Vincenzo Di Marzo, Justin C. Konje, George Kunos, Raphael Mechoulam, Pal Pacher, Keith A. Sharkey, Andreas Zimmer

Megjegyzések:	In 1964, the psychoactive ingredient of Cannabis sativa,D9-tetrahydrocannabinol (THC), was isolated. Nearly30 years later the endogenous counterparts of THC, col-lectively termed endocannabinoids (eCBs), were discov-ered: N-arachidonoylethanolamine (anandamide) (AEA)in 1992 and 2-arachidonoylglycerol (2-AG) in 1995. Sincethen, considerable research has shed light on the impactof eCBs on human health and disease, identifying anensemble of proteins that bind, synthesize, and degradethem and that together form the eCB system (ECS). eCBscontrol basic biological processes including cell choicebetween survival and death and progenitor/stem cellproliferation and differentiation. Unsurprisingly, in thepast two decades eCBs have been recognized as keymediators of several aspects of human pathophysiologyand thus have emerged to be among the most widespreadand versatile signaling molecules ever discovered. Heresome of the pioneers of this research field review the stateof the art of critical eCB functions in peripheral organs. Ourcommunity effort is aimed at establishing consensusviews on the relevance of the peripheral ECS for humanhealth and disease pathogenesis, as well as highlightingemerging challenges and therapeutic hopes.

Megjegyzések:	We have previously shown that i) endocannabinoids (eCB; e.g. anandamide [AEA]) are involved in the maintenance of homeostatic sebaceous lipid production (SLP) in human sebaceous glands (SG); and ii) eCB treatment dramatically increases SLP. Here, we aimed to investigate the expression of the major eCB synthesizing and degrading enzymes, and to study the effects of eCB uptake inhibitors on human SZ95 sebocytes, thus exploring the role of the putative eCB membrane transporter (EMT), which has been hypothesized to facilitate the cellular uptake and subsequent degradation of eCBs.We found that the major eCB synthesizing (NAPE-PLD, DAGL? and -?) and degrading (FAAH, MAGL) enzymes are expressed in SZ95 sebocytes, and also in SGs (except for DAGL?, whose staining was dubious in histological preparations). Interestingly, eCB uptake-inhibition with VDM11 induced a moderate increase in SLP, and also elevated the levels of various eCBs and related acylethanolamides. Finally, we found that VDM11 was able to interfere with the pro-inflammatory action of the Toll-like receptor 4 activator lipopolysaccharide.Collectively, our data suggest that inhibition of eCB uptake exerts anti-inflammatory actions and elevates both SLP and eCB levels; thus, these inhibitors might be beneficial in cutaneous inflammatory conditions accompanied by dry skin.
