Dementia, a traumatic and widespread neurodegenerative disorder, exerts its grip on countless people across the globe. As the disease advances, people grappling with dementia encounter considerable challenges in communication, decision-making, and problem-solving skills.
After appealing cellular results, PREP inhibitor treatment was likewise checked in a mouse model of frontotemporal dementia.
In a newly released paper, Professor Timo Myöhänens group from the Universities of Helsinki and Eastern Finland revealed that a PREP inhibitor reduces Tau build-up and toxicity likewise in the cellular models, including patient-derived nerve cells from frontotemporal dementia patients.
After appealing cellular outcomes, PREP inhibitor treatment was likewise tested in a mouse design of frontotemporal dementia. To follow the scientific circumstance, one-month treatment with the PREP inhibitor was started by the time of memory impairment. After treatment, mice that got the control treatment were performing inadequately in a memory test, but mice treated with the PREP inhibitor had typical cognitive abilities.
” Our essential discovery was that the PREP inhibitor treatment had reduced Tau accumulation in the brain locations associated with cognition and memory, also resulting in reduced oxidative tension markers that are typical in neurodegenerative diseases,” says Professor Timo Myöhänen.
” The arise from the memory tests after PREP inhibitor treatment were remarkably excellent, as treatments in comparable research studies are normally started before the symptoms, not after symptom onset. This supports the additional development of PREP-targeting drugs, and we are presently searching for financiers or partners for this”, Professor Myöhänen states.

The research was mainly carried out in Professor Myöhänens research study groups at the Universities of Helsinki and Eastern Finland, and groups from Harvard University, USA, and the University of Heidelberg, Germany, likewise took part in the study.
Dementia, a prevalent and distressing neurodegenerative disorder, exerts its grip on many people across the world. This condition manifests through a progressive decrease in cognitive functions, consisting of memory problems and the failure to perform routine activities. As the illness advances, people coming to grips with dementia encounter significant challenges in communication, decision-making, and analytical skills.
Researchers from the University of Helsinki have successfully shown that a compound understood as a PREP inhibitor can avoid the accumulation of a hazardous protein responsible for memory conditions, to name a few things.
This damaging protein buildup, similar to that seen in Parkinsons disease, is also observed in Alzheimers disease and other types of dementia. This procedure includes the formation of b-amyloid plaques and Tau protein aggregates within brain cells, which are known as neurofibrillary tangles. The dominating theory recommends that the production of Tau aggregates ultimately causes the death of neurons.
The quantity of Tau present aligns carefully with the severity of medical symptoms. Tau plays a crucial function, especially in a group of dementias known as Tauopathies, which include conditions like frontotemporal dementia.
