Neurological Disease Model: Brain Research Breakthrough

Blood-Brain Barrier‘s Role in Neurological diseases Under Scrutiny

Reutlingen, Germany – Scientists are intensifying their focus on the multifaceted role of the blood-brain barrier (BBB) in the onset and advancement of neurological disorders. This barrier,vital for safeguarding the brain from harmful substances,also presents a significant hurdle in delivering therapeutic drugs.

The Reutlingen University of Applied Sciences is spearheading an innovative project, “3D HIPSC-Brhs,” aimed at creating a realistic model of the human BBB in a lab setting.

Unlocking the Secrets Of The Blood-Brain Barrier

The “3D HIPSC-Brhs” project seeks to replicate the human blood-brain barrier in vitro, offering unprecedented insights into its function and dysfunction. This model is intended to boost research into neurological diseases, offering a platform for testing new therapies.

Dr. Ebru Ercan Herbst, head of the Project and professor of biochemistry and bioanalytics at the Faculty of Life Sciences, emphasized the project’s importance: “A deeper understanding of the blood-brain barrier is essential to declare her role in the development and progression of neurological illnesses and brain tumors. New findings are essential to develop a platform for choosing more effective medication that actually reach the brain.”

New Research Approaches

The project aims to generate various brain cell types and brain vessel cells from human stem cells. This will enable researchers to examine the blood-brain barrier under physiological conditions and observe its behaviour in the brain, which is crucial for evaluating the effectiveness of new therapies.

Specific disease models, such as schizophrenia, will be developed using stem cells from patients and healthy individuals to analyze disease-typical changes in the blood-brain barrier. This approach promises to contribute significantly to developing more effective therapies for neurological diseases and opens new perspectives for medical research and treatment of the brain.

The research work is scheduled for the next 18 months and is supported by the Carl Zeiss Foundation,which promotes new professions when starting application-oriented research at universities for applied sciences.

Did You Know? The Blood-Brain Barrier is so selective that some essential nutrients like glucose and amino acids require specific transport proteins to cross it.

Carl Zeiss Foundation Support

The Blood-Brain Barrier: An Evergreen Outlook

The Blood-Brain Barrier (BBB) continues to be a focal point in neurological research due to its critical function in maintaining brain health. Recent advancements highlight the potential for innovative treatments targeting BBB dysfunction in various neurological conditions.

One promising area involves using nanoparticles to deliver drugs across the BBB more efficiently.These nanoparticles are engineered to bypass the barrier’s selective permeability, allowing for targeted drug delivery to affected brain regions.Furthermore, researchers are exploring methods to temporarily and safely open the BBB to enhance drug penetration, although this approach requires careful monitoring to prevent unintended consequences.

The ongoing studies are also shedding light on the BBB’s role in neurodegenerative diseases like Alzheimer’s and Parkinson’s. Evidence suggests that BBB breakdown can exacerbate these conditions, leading to inflammation and neuronal damage. Understanding these mechanisms coudl pave the way for new therapeutic strategies aimed at preserving BBB integrity and slowing disease progression.
