„Endocannabinoids (ECs) are synthesized from membrane lipid precursors. Initiation of biosynthesis is triggered by specific signals, e.g. a rise in intracellular Ca2+ or the activation of metabotropic glutamate receptors. Thus, EC synthesis is “on-demand”, but synthesis may also occur at basal conditions. In order to evaluate the activity status of the EC system (ECS) in physiological and pathophysiological conditions, the determination of the EC levels is fundamentally important. In the Research Unit FOR926, the hypothesis has been put forward that the ECS is involved in the maintenance of the body‘s homeostasis, and that in pathological states, the ECS activity shifts to a new stable state, which may be called allostasis. To validate such a hypothesis, the detailed knowledge on the activity status of the ECS is mandatory. For the determination of EC levels, EC precursors and EC metabolites a highly sensitive LC-MS/ MS technology is required. Using this method, accurate tissue concentrations of these lipids will be obtained, with the confidence of the correct identity of the lipid under investigation. The Central Project CP1 of FOR926 provides a technology platform, which is essential for all the projects of FOR926, but also for performing internationally competitive cannabinoid research.“
