Figure 5From: Protein aggregation containing beta-amyloid, alpha-synuclein and hyperphosphorylated tau in cultured cells of hippocampus, substantia nigra and locus coeruleus after rotenone exposureIncreased hyperphosphorylation of tau after rotenone exposure. Photomicrographs illustrating the immunoreactivity of hyperphosphorylated tau in cultured cells of hipoccampus exposed to DMSO (A) or 0.5 nM of rotenone (B) for 48 hours. Arrows indicate sites of hyperphosphorylated tau, possibly aggregated, distributed throughout cytoplasm and neurites. Scale bar = 50 μm.Back to article page
