Investigating the role of reduced BDNF in depression and aging.


We have provided evidence of reduced BDNF signaling in postmortem brain of depressed subjects and of aged controls, and confirmed that low BDNF contributes to the molecular and behavioural changes associated with these conditions using mouse genetic models. Current efforts are aimed at characterizing underlying mechanisms and developing small molecules that target these deficits.
