MAPT and early-onset autosomal dominant Alzheimer disease: For example, soluble tau protein, a key pathogenic factor in Alzheimer's disease, undergoes a phase transition from liquid droplets to gel‐like condensates during maturation, ultimately assembling into large‐sized tau aggregates.[6] This underscores the importance of understanding how the size and physicochemical environments of condensates influence crucial biomolecular processes, particularly in crowded intracellular settings.
