New York, Feb 16 (NationPress) A groundbreaking platform for antibody discovery has been developed, allowing researchers to explore the intricate mechanisms associated with Alzheimer's and Parkinson’s diseases.
In conditions such as Parkinson's and Alzheimer's, certain proteins misfold and aggregate, leading to the formation of toxic clusters that harm brain cells.
This phenomenon, known as protein aggregation, has prompted researchers to create innovative strategies for generating antibodies that specifically target these aggregates, serving as probes or modulators of the aggregation process.
This novel approach addresses significant obstacles in characterizing these complex and frequently transient protein structures.
Antibodies are renowned for their precise binding capabilities, making them a valuable asset for studying these structures. However, the generation of antibodies against such fleeting targets has previously posed a considerable challenge.
This new platform merges computational design with directed evolution to create antibodies that are subsequently screened for their capacity to bind to target aggregates or impede the aggregation process.
“We can dramatically accelerate the discovery and production process, conserving both time and resources,” stated Francesco Aprile, PhD, Associate Professor in Biological Chemistry at Imperial College London, who spearheaded the study.
Utilizing this platform, Aprile and his team successfully produced single-domain antibodies (nanobodies) aimed at intrinsically disordered proteins—proteins that lack a definitive three-dimensional structure and are in a constant state of flux.
“These intrinsically disordered proteins self-assemble, forming oligomers and aggregates like amyloid fibrils, which are characteristic of Alzheimer’s,” Aprile emphasized.
The nanobodies created by the researchers can target various assemblies of amyloid-beta and alpha-synuclein, proteins linked to Alzheimer's and Parkinson's diseases, respectively.
These nanobodies hold the potential to yield critical insights into the factors that lead these proteins to form harmful oligomers.
“Our platform signifies a major leap forward in our ability to investigate protein self-assembly,” Aprile remarked. “By efficiently producing nanobodies against these challenging targets, we can now explore the mechanisms behind these processes and their implications in disease.”
Crucially, the research has pinpointed specific regions within amyloid-beta and alpha-synuclein that could serve as promising therapeutic targets. This finding paves the way for new drug development avenues aimed at tackling Alzheimer’s and Parkinson’s.
By focusing on these key protein assemblies, we may have the opportunity to slow or even halt disease progression, Aprile concluded.
The Biophysical Society has been founded to spearhead the development and sharing of knowledge in biophysics.
