Issued Patent Spotlight: Novel Approach to Protein Aggregation in Neurodegenerative Disease
Congratulations to UAMS inventors Dr. Robert Reis, Dr. Peter Crooks and Dr. Srinivas Ayyadevara on the issuance of a new patent for a promising approach to targeting protein aggregation in neurodegenerative disease. Neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s disease are often linked by one major biological challenge: the buildup of toxic protein aggregates in the brain and central nervous system. While many therapies focus on managing symptoms or addressing downstream effects, there remains a significant need for approaches that target protein aggregation more directly. This newly issued patent covers methods using combretastatin-A4 (CA4) and related analogs to prevent or reduce protein aggregation through compounds that bind glial fibrillary acidic protein (GFAP). The technology represents a new therapeutic direction for aggregation-associated disorders and suggests a potential disease-modifying strategy across multiple neurodegenerative indications. Preclinical studies described in the patent showed encouraging findings across several model systems, including reductions in aggregate burden, decreases in amyloid accumulation, improved disease-related phenotypes, and lifespan extension in nematode models. Together, these results support the potential of a CA4-based platform as a differentiated approach for targeting protein-aggregation pathology in the central nervous system.
