A reduced mathematical model to explore Gi/Gs preferences of the CB1 receptor

Introduction: The cannabinoid type 1 receptor (CB1) induces both Gi and Gs (G-protein) pathways. The Gi pathway inhibits cyclic adenosine monophosphate (cAMP) production and Gs stimulates cAMP responses, the net cAMP response is therefore a mixture of the effects of the two pathways. CB1 shows a preference for the Gi protein and produces a net […]

A mathematical model of CB1 receptor allosteric modulation

Introduction: The type 1 cannabinoid receptor (CB1) is among the most abundant G-protein coupled receptors in the central nervous system.  CB1 modulates neurotransmission, and plays a vital role in both physiology and pathology.  Allosteric ligands bind to a different site on the receptor to the endogenous (orthosteric) ligand and can have effects that are unique […]
