Genetically-targeted photorelease of endocannabinoids enables optical control of GPR55 in pancreatic β-cells

Janelle M Tobias, Gabriela Rajic, Alexander E G Viray, David Icka-Araki, James A Frank. Chem Sci. 2021 Sep 15;12(40):13506-13512.

Laboratory studyOther animals

Design
Laboratory study
Subjects
Pancreatic beta-cells in culture
Dose used in the study
Photocaged palmitoylethanolamide (OCT-PEA) released by light at genetically targeted membranes; concentration not stated in the abstract
Duration
Not stated in the abstract
What was measured
Calcium activity in beta-cells after light-triggered release of PEA at the plasma membrane.

What the authors reported

The OCT-ligand method allowed PEA to be released at defined cell membranes. Released PEA showed that plasma membrane GPR55 stimulates beta-cell calcium activity through phospholipase C.

Limits of this study

A chemical tool development study in cultured cells; it cannot show effect in people or animals treated in practice. There are no conflicts to declare.
