A team of researchers at the Case Western Reserve University School of Medicine has taken a major step toward understanding the mechanisms involved in the formation of large clumps of tau protein, a hallmark of Alzheimer's disease and several other neurodegenerative disorders.

Their findings may help to better understand the pathological process and possibly lead to developing medications to treat such devastating brain diseases.

The study, "Regulatory mechanisms of tau protein fibrillation under the conditions of liquid-liquid phase separation," was published this week in the journal Proceedings of the National Academy of Sciences.

The senior author of the study is Witold Surewicz, a professor of physiology and biophysics at the School of Medicine. Solomiia Boyko, a graduate student, and Krystyna Surewicz, a senior research associate, co-authored the study, which was supported by the National Institute on Aging.
