TRPM2 is a non-selective cation channel which is permeable to calcium. Although expression is highest in the brain, the physiological role for TRPM2 in neurons was unknown. Furthermore, our understanding of the pathways regulating TRPM2 channel function required further investigation. In this thesis, we identified that TRPM2 is required for NMDAR-dependent long-term depression (LTD). No change in NMDAR expression or function was observed following genetic deletion of TRPM2. Instead, the loss of NMDAR-LTD in TRPM2 knockout mice results from diminished GSK-3β activation. We next examined whether age in vitro could facilitate TRPM2 currents. We demonstrate that diminished glutathione with age …
