Research Interests

  • Disease of the retina
  • Determine the molecular and activity-dependent mechanisms that regulate synaptic connectivity between retinal neurons during development and circuit assembly
  • Determine the structural and functional impact of retinal disease on synaptic connectivity between outer and inner retinal neurons
  • Correlate synaptic plasticity mechanisms during retinal development and during disease conditions
  • Determine genetic and/or pharmacological strategies that can recover synaptic organization and function in retinal disease conditions

Research Highlights

One recent international collaborative project from the Hoon Lab was together with Drs. Ann Marie Craig and Tabrez Siddiqui at the University of British Columbia and University of Manitoba, respectively. This project elucidated a novel role for a synapse organizing protein, Leucine-rich repeat transmembrane neuronal proteins (LRRTM4), in the function of the sensory retinal circuit critical for dim-light vision. LRRTM4 was thought to only be essential for the function of excitatory synapses, but this project found that LRRTM4 also organizes inhibitory synapses. The work could have far-reaching implications since it is known that mutations in LRRTM4 are associated with visual defects.
