Two Waisman investigators were recently awarded a new professor title track at UW-Madison.

Alexander disease (AxD) is a devastating leukodystrophy caused by gain-of-function mutations in GFAP, and the only available treatments are supportive. Recent advances in antisense oligonucleotide (ASO) therapy have demonstrated that transcript targeting can be a successful strategy for human neurodegenerative diseases amenable to this approach.
Promising treatment for Alexander disease moves from rat model to human clinical trials
Alexander disease is a progressive and rare neurological disorder with no cure or standard course of treatment. But a new study led by researchers at the University of Wisconsin–Madison involving a rat model of the disease offers a potential treatment for the typically fatal condition.

Alexander disease (AxD) is a rare neurodegenerative disorder that is caused by dominant mutations in the gene encoding glial fibrillary acidic protein (GFAP), an intermediate filament that is primarily expressed by astrocytes. In AxD, mutant GFAP in combination with increased GFAP expression result in astrocyte dysfunction and the accumulation of Rosenthal fibers.

Alexander disease results from gain of function mutations in the gene encoding glial fibrillary acidic protein (GFAP). At least eight GFAP isoforms have been described, however, the predominant alpha isoform accounts for approximately 90% of GFAP protein.
Progress made toward treatment for rare, fatal neurological disease
After more than a decade of work, researchers at the University of Wisconsin–Madison’s Waisman Center reported promising results in the lab and in animal models that could set the stage for developing a treatment for Alexander disease, a rare and usually fatal neurological disease with no known cure.
Rare disease yields clues about broader brain pathology
Alexander disease is a devastating brain disease that almost nobody has heard of — unless someone in the family is afflicted with it. Alexander disease strikes young or old, and in children destroys white matter in the front of the brain.
