Study highlights crucial role of immune-system molecule in Huntington's disease

More than a decade before people with Huntington's disease show symptoms, they can exhibit abnormally high levels of an immune-system molecule called interleukin-6 (IL-6), which has led many researchers to suspect IL-6 of promoting the eventual neurological devastation associated with the genetic condition.
