Image: A photmicrograph of medium spiny neurons (yellow) with nuclear inclusions (orange), which occur as part of the Huntington\'s disease process. Several neurons are colored yellow and have a large central core with up to two dozen tendrils branching out of them. The core of the neuron in the foreground contains an orange blob about a quarter of its diameter (Photo courtesy of Wikimedia Commons).

Seeding Assay May Boost Search for Huntington's Disease Drugs

An assay technique that measures seeding of mutant huntingtin aggregates in cerebral spinal fluid may identify individuals with Huntington's disease that have not yet become symptomatic and may be used to evaluate the efficacy of new drug treatments for the disease.  More...
