DAGLB and anxiety disorder: Of relevance, a recent study investigating gene expression change in response to exposure‐based CBT for anxiety disorders reported that an increase in DALGB gene expression (diacylglycerol lipase beta gene), which is involved in the biosynthesis of 2‐AG (an endogenous endocannabinoid), was associated with greater reductions in severity while a reduction in DALGB expression corresponded with lower reductions in severity [Roberts et al., 2016].
