Alzheimer’s disease (AD) arises from molecular events that scientists are piecing together to discern an overall story, parts of which are well known, others less so. Some of the lesser-known epigenetic events in the Alzheimer’s story have just been filled in by scientists based at the Van Andel Research Institute (VARI). What’s more, these epigenetic events, which occur early in Alzheimer’s, appear to fit well with what we know about the disease’s progression to its most devastating biological features.
