Description
The discovery and development of inhibitors of fatty acid amide hydrolase (FAAH)

In the 3Tg-AD transgenic mice model, CB1 mRNA is increased in the prefrontal cortex, dorsal hippocampus, and basolateral amygdala complex, while decreased in ventral hippocampus of animals with 6 and 12 months of age, but not at 2 months of age (Manuel et al., 2014)

On a chemical level, L-carnitine is a -hydroxy--trimethyl-aminobutyric acid
