Protein aggregation is a process in which proteins misfold or unfold, causing them to form aggregates or clumps. These aggregates can disrupt normal cellular processes and lead to diseases such as Alzheimer's, Parkinson's, and Huntington's. Research in this area aims to understand the mechanisms behind protein aggregation, develop strategies to prevent or reverse it, and discover potential therapeutic targets for treating protein aggregation-related diseases. Techniques such as bioinformatics, structural biology, and cell biology are commonly used in this field of study.
