Mutant huntingtin protein pokes holes in cells’ nuclear membrane

Clumps of the mutant huntingtin protein, which are the known cause of Huntington’s disease, poke holes in the membrane that surrounds and protects cells’ DNA-filled nucleus, according to preclinical research. These protein aggregates had tiny, protruding fibers that damaged the membrane, which is called the nuclear envelope. Lab-grown cells…

Healthy habits before symptoms show may slow disease progression

A high level of education, low to moderate alcohol intake, not smoking, and controlling one’s weight may slow Huntington’s disease progression among those who’ve yet to have symptoms, a study shows. “Reducing modifiable risk factors for [Huntington’s] is one way to support the presymptomatic population,” which is made up…

PTC518 lowers mutant HTT, slows disease progression: Interim data

An investigational oral therapy from PTC Therapeutics called PTC518 safely and effectively reduces levels of the mutant huntingtin protein (mHTT) in Huntington’s disease patients, while being linked to trends of slower disease progression. That’s according to one-year interim data from the ongoing Phase 2a PIVOT-HD clinical trial…
