Designer Drugs for Designer Receptors: Unlocking the Translational Potential of Chemogenetics

摘要

Chemogenetic techniques allow selective manipulation of neurons by activating engineered actuator proteins with otherwise inert effector molecules. A recent study (Magnus et al. Science 2019;364: eaav5282) describes the coevolution of highly potent actuator effector pairs based on a clinically approved antismoking drug. These tools allow selective excitation or inhibition of neurons in the living brain with high specificity and no detectable side-effects.
