“Excellent Innovation” in Treatment of Alzheimer’s Disease by Prof. Dr. Yusuf Yağcı

Niemann-Pick Type C (NP-C) disease, known as “Childhood Alzheimer’s”, is known as a genetic disorder seen in 1 out of 100,000 people in the EU, according to research. The disease impairs the function of the protein, which regulates cholesterol traffic, ensures its recycling or reuse. This causes cholesterol to accumulate in the brain, liver and spleen. Accumulation of cholesterol causes brain damage and inevitably reduces cognitive skills and mobility. Typically diagnosed in childhood, NP-C is rapidly progressing to life-threatening levels in the second or third decade of life. The scientific world was looking for solutions for the treatment of the disease. At this point, an important contribution to the solution came from the NanoMop project coordinated by Prof. Dr. Yusuf Yağcı from ITU Faculty of Science and Letters, Department of Chemistry and carried out by Dr. Antonino Puglisi under the European Union Horizon 2020 Marie Skłodowska-Curie Program. The project examines the potential of Cyclodestrins (CDs), which are naturally occurring sugars, in the treatment of the disease by drawing attention to their cholesterol removal capabilities. A synthetic method has been developed to create polymeric nanoparticles containing “β-Cyclodextrin” (β-CD) substance to create a remedy for infant or childhood Alzheimer's disease, especially because it creates cholesterol in the brain. ITU scientists have demonstrated that it is possible to solve the problem by embedding CDs in larger macromolecular structures with a published study titled “pH-responsive polymer nanoparticles as potential therapeutic tools for cholesterol-associated diseases”.

NanoMop Enters the Europe’s Innovation Radar

The research on the therapeutic effect of CDs by Prof. Dr. Yusuf Yağcı of ITU Faculty of Science and Letters, Department of Chemistry and Dr. Antonino Puglisi was selected as the “excellent innovation” by the EU Commission. As of 20 July 2020, projects supported by ITU and other institutions were included in the Innovation Radar of the European Research Association.

The discovery, whose biological applications are still being carried out by a group of experts in Oxford, the β-CD substance is separated from the polymer in a slightly acidic environment, it contains cholesterol with its ringed structure and allows it to be expelled. Usually the β-CD substance cannot overcome the brain barrier due to its molecular size and cannot be administered via blood. In the studies carried out at ITU, this substance has been bound to the polymer structure and can be turned into nanoparticles. Due to its small size, it can overcome this barrier and in a very slightly acidic environment, the β-CD can be separated from the nanoparticle and independently removed from the environment by taking cholesterol into its structure.
