Visinin–like protein–1 as a CSF Biomarker in Alzheimer disease

CSF levels of tau and Aβ42 are well known markers of Alzheimer disease.  Recently, Visinin–like protein–1, which is a highly expressed neuronal calcium–sensor protein, has been shown to not only be a marker of neuronal injury, but also a potential marker of annual cognitive decline.  Visinin–like protein–1, also known as VILIP–1, has been detected in close association with amyloid plaques, but does not appear to be a component of neurofibrillary tangles.  In the study cohort featured in this week’s issue, VILIP–1 predicted future cognitive decline in early Alzheimer disease over the follow–up period at least as well as tau and Aβ42, supporting the potential utility of CSF VILIP–1 as a biomarker for neurodegeneration in AD.
