Brief Biography

Dr. Michael Salter is Chief of Research at The Hospital for Sick Children (SickKids), a Senior Scientist in the Program in Neurosciences & Mental Health, and a Professor of Physiology at the University of Toronto.  

Salter received an MD degree from the University of Western Ontario in 1982 and went on to obtain a Ph.D. in Physiology from McGill in 1987. After post-doctoral training at Toronto Western and at Mt. Sinai hospitals, he joined the Research Institute of SickKids in 1990. From 1999 to 2009 Salter was the founding Director of the University of Toronto Centre for the Study of Pain. Salter’s main research focus is on synaptic physiology, in particular in relation to pain, and he has done groundbreaking work that has led to new paradigms about neuroplasticity and about how synaptic transmission in the central nervous system is regulated by biochemical processes within neurons and by glial-neuronal interactions. His discoveries have broad implications for the control of cell-cell communication throughout the nervous system and his work has regularly appeared in elite journals including Nature, Science, Cell, Nature Medicine and Neuron.  Salter has a broad interest in neuroscience and his work relevant to learning and memory, stroke-induced neuron death, epilepsy and schizophrenia. As a distinct line of research, he and his collaborators reported in Cell in 2006 their discovery of a previously unsuspected role for sensory neurons in the pathogenesis of diabetes and in the control of glucose homeostasis.  

To facilitate the translation of his fundamental studies to the development of new therapies for humans, Salter is a founding scientist and actively involved in two startup biotech companies – NoNO Inc and Afference Therapeutics. Salter currently holds the Northbridge Chair in Paediatric Research.  He has received numerous awards including the E.B. Eastburn Award, the John Charles Polyani Prize in Physiology or Medicine, the Early Career Investigator Award of the Canadian Pain Society, the Distinguished Career Investigator Award of the Canadian Pain Society, and was an International Research Scholar of the Howard Hughes Medical Institute.  He is a Fellow of the Royal Society of Canada.

Research Interests

Work in my laboratory is primarily directed to elucidating fundamental principles of cell-cell signaling in the central nervous system and to understanding how aberrations in signaling underlying nervous system disorders.  We are using the understanding we have developed to devise new approaches to restoring physiological signaling, often through manipulating protein-protein interactions within cells.   

One main area of focus is on transmission, plasticity and signaling at glutamatergic synapses where we are studying biochemical processes that regulate the function and localization of the NMDA receptor subtype of glutamate receptor.  We have identified several physiological regulatory mechanisms and are examining the potential role of alterations in these regulatory processes in disorders ranging from chronic pain, to epilepsy and to schizophrenia. We are now using neurons derived from induced pluripotent stem cells (iPSCs) to study glutamatergic signaling in cells from normal humans and those with neurodevelopmental disorders.

A second main area of focus is on microglia-neuron signaling, which stems from our discoveries on the role of this signaling in persistent pain hypersensitivity.  We are identifying the  mechanisms by which microglia cause neuronal hyperexcitability with the goal of counteracting these mechanisms in order to devise strategies for new types of pain relieving medications.

A third main area of research is on the role of primary sensory neurons in controlling and interacting with the immune system.  This work stems from our discovery that hypofunction of the ion channel TRPV1, also known as the capsacin receptor, in sensory neurons in critical for the pathogenesis of diabetes in the non-obese diabetic (NOD) mouse.   We have recently identified new pathological roles for TRPV1 in models of other autoimmune disorders.
