Understanding the molecular events which cause Batten Disease

Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) or Batten Disease is a lethal progressive neurodegenerative disease in children, caused by mutations in the CLN3 protein. The function of CLN3 is unknown and previous research suggests it may be involved in lipid metabolism, galactosylceramide transport, vesicular trafficking, and endocytosis. Unpublished data from the Davidson lab has shown that brain microvasculature endothelial cells derived from CLN3 KO mice, have a reduction in fluid phase endocytosis (FPE). When CLN3 was restored to endogenous levels in these cells using lentiviral gene transfer, the defect in FPE was alleviated. My thesis project is centered on investigating the molecular defects causing the FPE cellular phenotype.
