摘要
Folding and unfolding are crucial ways of modulating biological activity and targeting proteins to different cellular locations. In the living system, protein folding occurs in a very crowded environment, often assisted with helper proteins. In some cases this pathway can go off beam and the protein can either misfold or aggregate or form structures of elongated-unbranched morphology known as amyloid fibrils. Protein folding is not just an academic matter. Recombinant biotechnology and pharmaceutical industries are some of the fields where both theoretical and practical knowledge of protein folding is required. Misfolded protein and amyloid fibrils that escape the cellular quality control check are the basic reason of a number of increasingly widespread neurodegenerative diseases such as Alzheimer's and variant Creutzfeldt-jakob etc. Thus, protein folding study also emerges as an interesting area in the field of biomedical research. This review deals with basic concepts related to protein folding and misfolding forming toxic aggregates and amyloid fibrils as well as disease associated with them. A more practical approach will be revealed to the early diagnosis of aggregation-prone diseases and amyloid states and their balanced therapeutics.
