Summary: Accumulation of β-amyloid in the brain is considered one of the main causes of Alzheimer’s disease. The increase in β-amyloid is accompanied by a reduction in levels of the high affinity nerve growth factor receptor (trkA) and cognitive impairment. The authors looked at levels of the low affinity nerve growth factor receptor (p75) that do not decline. Using a 0.8-μg injection of 192-Cy3 (Cat. #FL-01) into the medial prefrontal cortex of rats the authors assessed the transport of p75 and β-amyloid by microscopy. The results indicate that the primary destinations of both p75 and β-amyloid were the late endosome and lysosome.
