Unraveling Chaperone Dynamics: Molecular Insights into Protein Folding and Neurodegeneration

Protein folding is essential for maintaining physiological functions, and improper folding can lead to the formation of toxic aggregates such as amyloids, implicated in various diseases including neurodegenerative disorders. To counteract these misfolded proteins, cells rely on an elaborate system of molecular chaperones that assist in both protein folding and disaggregation. Despite the critical role of chaperones, the transient and dynamic nature of their interactions with substrates leaves many aspects of their mode of action poorly understood. Recent advances in technologies like cryo-electron microscopy (cryo-EM) offer new opportunities to delve deeper into these interactions, especially for proteins larger than 50 kDa, potentially providing a clearer picture of intermediate chaperone-chaperone complexes.This Research Topic aims to decipher the complex process of chaperone-mediated folding and disaggregation, emphasizing the mechanisms linked to neurodegeneration. While some insight into chaperone interactions has been achieved, a comprehensive understanding remains elusive, particularly concerning the full-size proteins and the transient states important in these processes. Additionally, understanding the kinetics of chaperone interactions with substrates is fundamental to linking their structural configurations to their biological functions, a crucial step in targeting these molecules as therapeutic agents in neurodegenerative diseases.To further illuminate the intricacies of chaperone-substrate interactions, this Research Topic includes a wide range of contributions.
