Discovery of a new on/off switch affecting cell-to-cell communications

Cellular functions rely on several communications networks that allow cells to respond to signals affecting the organism. A new study published in Molecular Cell has revealed a mechanism that shuts down a major cell-to-cell communications pathway implicated in a number of diseases. INRS professor Nicolas Doucet and his research team contributed to the discovery of this new molecular switch, shedding new light on the role of receptor tyrosine kinases, a well-known protein family whose function is still being explored.
