Research interests :

We study the role of opioid receptors in pain control, addictive behaviors and emotional responses. We explore the genetic basis of neuroadaptations to drugs of abuse. We also study the role of N/OFQ neuropeptide in cognitive and emotional processes.
Our laboratory combines in vitro and in vivo mutagenesis with pharmacological approches, cellular imaging and behavior.

Highlight :

We recently have created knockin mice expressing functional fluorescent opioid receptors instead of native receptors: the receptor is directly visible in vivo. The movie shows real-time receptor internalization in live neurons, under opioid stimulation. (Movie)
