Researchers have developed a new mouse model that affects nerve cells in the eye that could help in studying disease mechanisms and treatment approaches in Parkinson’s disease. A hallmark of Parkinson’s disease is the formation of Lewy bodies, abnormal and insoluble protein deposits that build up in nerve cells and cause them to degenerate. VPS35 mutations also have been linked to Alzheimer’s disease, so the scientists are planning studies that would use the new mouse model to investigate that neurodegenerative condition. By that time, large protein clumps similar to Lewy bodies could be observed in the eye. The study, -Mutant mice with rod-specific VPS35 deletion exhibit retinal α-synuclein pathology-associated degeneration,” was published in Nature Communications. Microglia, the brain-resident immune cells that help engulf and remove waste products like alpha-synuclein became abnormally activated and moved into the retinal region. One protein, VPS35, helps distribute various molecules to where they’re needed, including sending abnormal proteins off for degradation.
