ncomms10955-f5Gyorgy had a pioneering role in identifying the role of MICU1 in regulating mitochondrial Ca2+ uptake, see:

MICU1 regulation of mitochondrial Ca(2+) uptake dictates survival and tissue regeneration.

MICU1 controls both the threshold and cooperative activation of the mitochondrial Ca²⁺ uniporter.

His previous ‘Greatest Hits’ listed in the Scientist

  • Visualized mitochondrial energy production and ion metabolism in single live cells.
  • Characterized the behavior of IP3 receptors in cells and described how they produce calcium spikes.
  • Demonstrated that calcium spikes stimulate ATP production in mitochondria, and identified the molecular mechanism by which this occurs.
  • Discovered a physical tether between mitochondria and the endoplasmic reticulum and described its role in signaling.
  • Determined how mitochondrial movements are controlled inside a cell.
  • Used real-time, live-cell imaging to observe transient mitochondrial fusion events—aka “kiss and run.”
