Endothelial CB1 receptors heighten arterial inflammation and lipid uptake in atherosclerosis. Removing endothelial CB1 or using antagonists reduces these effects. PMID:42414306, Nat Commun 2026, @NatureComms https://doi.org/10.1038/s41467-026-75214-2 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Endothelial cannabinoid CB1 receptor deficiency reduces shear stress-induced arterial inflammation and lipid uptake | Nature Communications
Peripheral cannabinoid CB1 receptor antagonists that lack central nervous system effects are emerging as promising therapies for metabolic disease, yet the role of endothelial CB1 signaling in atherosclerosis remains unclear. Here, we show that endothelial CB1 is expressed in human atherosclerotic plaques, is induced by oscillatory shear stress in atheroprone flow regions, and promotes vascular inflammation, permeability and lipid uptake. Endothelial-specific Cnr1 deletion or peripheral CB1 antagonism in mice attenuates atherosclerosis, reduces endothelial caveolae–dependent low-density lipoprotein uptake by downregulating caveolin-1 and ALK1 expression, and improves metabolic parameters in brown and white adipose tissue and the liver. The anti-atherogenic and metabolic effects are more pronounced in females, which is possibly linked to estrogen signaling. These findings identify endothelial CB1 as a proatherogenic, sex-biased regulator of vascular lipid transport and plaque developmen

I hope doctors finally learn, that if the endothelial layer of your blood vessels are utterly destroyed you can’t improve vasoconstriction through EXERCISE. You can’t “retrain vascular dysfunction.” This is very 1990.

🌙✨📚📚📚🎩📖 right, so

Endothelial Dysfunction: viral fragments or the immune system damage this layer, it triggers endothelial dysfunction, causing the vessel walls to lose their normal function, become "leaky," promote abnormal clotting.
Yeah it’s a bummer. You should have let people heal before work

4) For endothelial activation they measure Von Willebrand factor (VWF, helps platelets stick) and thrombomodulin (sheds when the endothelium is damaged).

Measures of platelet activation included P-selectin and sCD40L.
