Optogenetics: using light to fight chronic pain

Research by Dr. Philippe Séguéla and his team, in collaboration with many members of the pain research network, shows that a treatment with light can alleviate pain in genetically modified mice by specifically turning off the activity of neurons expressing pain receptors called Nav1.8 + nociceptors. This optogenetic approache, using light to control gene expression, has multiple advantages, since it depends on a non-invasive treatment, light, that can be applied in a controlled and precise manner, thereby controlling the activity of specific neurons.

Read a recent profile of Manon Choinière, professor of anesthesiology at the Université de Montréal, in which she discusses the biological, psychological and social consequences of pain.  She highlights the fact that chronic pain affects more that 20% of Canadians, and costs more to Canada than cardiovascular disease, diabetes and cancer.   The article presents an overview of Dr. Choinière's recent research projects and collaborations.
