- Identifying key proteins can lead to new therapeutic targets.
- Interdisciplinary approaches enhance neurodegenerative research.
New Delhi, March 2 (NationPress) A team of researchers has achieved a major milestone in unraveling the function of the tau protein in Alzheimer’s disease.
Utilizing human induced pluripotent stem cells (iPSCs), scientists from the University of Cologne in Germany have demonstrated that a particular variant of the tau protein, identified as the 1N4R isoform, plays a crucial role in mediating the harmful impacts of protein aggregates within human brain cells.
This research, featured in the journal Alzheimer’s & Dementia, was directed by Dr. Hans Zempel from the Institute of Human Genetics, who also leads a group in the Career Advancement Program (CAP) at the Center for Molecular Medicine Cologne (CMMC) affiliated with the University of Cologne and University Hospital Cologne.
In individuals affected by Alzheimer’s disease, certain proteins build up in brain cells, forming clumps that hinder normal cellular function or may lead to cell death.
The team, including Dr. Buchholz and Dr. Zempel, employed cutting-edge methodologies such as CRISPR/Cas9 gene editing and live-cell imaging on human iPSCs to reveal that the 1N4R tau isoform is responsible for the detrimental cellular effects. iPSCs are human stem cells that can be derived from other cell types.
For instance, skin cells can be reprogrammed into iPSCs, which can subsequently be transformed into brain cells (neurons).
The researchers evaluated various forms of tau protein by selectively expressing them in neuronal cells.
This method allowed the team to investigate the impact of each protein isoform on cellular health.
Dr. Sarah Buchholz remarked that this research marks a significant leap in our comprehension of Alzheimer’s disease mechanisms.
“Identifying 1N4R tau as a pivotal protein unveils a potential new target for future therapeutic interventions,” Buchholz emphasized.
The interdisciplinary nature of the study not only enhances our understanding of Alzheimer’s disease but also underscores the significance of human cell models in neurodegenerative research.
