Bruce Pfeffer PhD
SUNY Buffalo, Cell Biology
Current Position: Senior Postdoctoral Scientist
Keywords Research Areas: retinal pigment epithelium; oxysterols; oxidative stress; autophagy; cell-based assays
Research Focus:
  • Retinal Diseases
  • Retinal Neuroscience
Clinical Relevance:
  • Age-Related Macular Degeneration
  • Retinitis Pigmentosa/Retinal Degenerations
Synopsis Of Research:

Cultured retinal cells are exposed to oxysterols as a model of retinal degeneration associated specifically with Smith-Lemli-Opitz syndrome--a metabolic gene defect leading to accumulation of 7-dehydrocholesterol, the precursor of cholesterol--and as a general in vitro model for studying the response of these cells to oxidative stress and also intrinsic mechanisms of cell protection and death.
