LY-2183240 enhances reward-seeking behavior with inducing neuronal excitation and early apoptosis in mouse.

Cannabinoids interact with cannabinoid receptors, influencing diverse central nervous system (CNS) and peripheral functions, including anxiety, depression, and cognition. CB1 and CB2 receptors modulate signaling cascades via G-protein coupling, with anandamide acting as an endogenous ligand for CB1 receptors. LY-2183240, a putative endocannabinoid transport blocker, elevates brain anandamide levels, showing therapeutic potential in pain management and alcohol-related behaviors.

The compartment-specific manipulation of the NAD/NADH ratio affects the metabolome and the function of glioblastoma.

Glioblastoma multiforme (GBM) is the most aggressive type of cancer in the brain and has an inferior prognosis because of the lack of suitable medicine, largely due to its tremendous invasion. GBM has selfish metabolic pathways to promote migration, invasion, and proliferation compared to normal cells. Among various metabolic pathways, NAD (nicotinamide adenine dinucleotide) is essential in generating ATP and is used as a resource for cancer cells.

Serum neurofilament light chain levels are correlated with the infarct volume in patients with acute ischemic stroke.
