Abu Dhabi Stem Cells Center (ADSCC) has announced a major scientific breakthrough in Huntington’s disease research, identifying a previously unrecognized biological mechanism that could support the development of future targeted therapies for the rare inherited neurological disorder. Using patient-derived stem cell technology and advanced brain models, researchers discovered that astrocytes specialized support cells in the brain play a far greater role in disease progression than previously understood.
The research found that the mutant huntingtin protein disrupts critical molecular pathways responsible for producing Glial Fibrillary Acidic Protein (GFAP), an essential structural component for healthy astrocyte function. By restoring these disrupted pathways with therapeutic compounds, researchers successfully reversed cellular abnormalities and restored normal astrocyte structure and function in laboratory models.
Dr. Fatima Al Kaabi, Consultant Hematologist and Bone Marrow Transplanter, Executive Director of the Abu Dhabi Bone Marrow Transplant Program at ADSCC, and Board Member of ADSCC / Yas Clinic Group, said: “This breakthrough reflects ADSCC’s continued commitment to advancing scientific discovery and translating cutting-edge research into future therapeutic opportunities for patients. Through sustained investment in stem cell research, regenerative medicine, and precision medicine, we continue to strengthen Abu Dhabi’s position as a regional and international center for biomedical innovation.”

Professor Angelo L. Vescovi, Professor of Cell Biology and lead researcher, said: “Through over three decades, Huntington’s disease research has focused primarily on neurons. Our study shows that astrocytes play a far more critical role in disease progression than previously understood. By identifying the molecular mechanisms responsible for their dysfunction, we have uncovered a new biological target that could fundamentally change how future therapies for Huntington’s disease are developed.”

The findings were further validated in genetically engineered fruit fly models, where treated subjects demonstrated significant improvements in motor function compared to untreated models. The study also highlights the potential of patient-derived stem cell platforms to accelerate research into other neurological and genetic disorders, including ALS, Alzheimer’s disease, Parkinson’s disease, leukodystrophies, and sickle cell disease. The findings are expected to be published in a peer-reviewed scientific journal, marking another milestone in translational biomedical research.
