ICRS 2018: Report from Leiden (Part 2)

During the first week of July 2018, five-hundred-and-thirty-five delegates from five continents met at the University of Leiden in the Netherlands for the 28th annual symposium of the International Cannabinoid Research Society (ICRS). The four-day conference showcased recent scientific discoveries about cannabis components and various ways of targeting the endocannabinoid system to improve health outcomes.

Fatty acid binding proteins

During his Young Investigator Award Presentation, Stony Brook University scientist Martin Kaczocha discussed the role of fatty acid binding proteins (FABPs) as critical components of the endocannabinoid system. This is an emerging area of medical science with exciting prospects for pharmaceutical development. Kaczocha’s talk focused on preclinical investigations that underscored the potential of targeting specific FABPs to treat pain, inflammation and prostate cancer.

Why are fatty acid binding proteins important? Because fats and water don’t mix well, and that means endocannabinoids (eCBs) and other endogenous lipids must rely on FABPs to get to where they need to go.

FABPs are transport molecules – think of them as a fleet of teleporting canoes – that shuttle eCBs through the cell membrane into the aqueous cytoplasmic interior. Within the cell, eCBs act upon nuclear receptors, which regulate gene expression and mitochondria, before they translocate to enzymes that metabolize eCBs into breakdown components as part of the natural life cycle of these pivotal neurotransmitters.

In 2009, Stony Brook scientists, led by Dale Deutsch, identified several FABPs as “intracellular carriers” for the endocannabinoid anandamide. Six years later Deutsch and Koczocha scored another breakthrough when they reported that the same FABP transport molecules also serve as intracellular carriers for CBD and THC.

What happens when plant cannabinoids like CBD and THC compete with endogenous cannabinoids for seats on the same FABP canoe? CBD and THC reduce eCB access to FABP transport
