Professor Yoshiharu Deguchi and Professor Hiroki Otani exhibited at Biojapan 2025Itabashi Campus

Professor Yoshiharu Deguchi of the Faculty Faculty of Pharmaceutical Sciences at Teikyo University and Professor Hiroki Otani of the Department of Department of Radiological Technology Faculty of Medical Technology exhibited their research at Biojapan 2025, which was held at Pacifico Yokohama (Yokohama, Kanagawa Prefecture) from Wednesday, October 8th to Friday, October 10th, 2025.
This exhibition was a large-scale matching event that promoted collaborative research and commercialization among domestic and international companies and universities involved in the bioindustry, including drug discovery, healthcare, and energy. Approximately 1,600 companies exhibited over the three days, and 22,167 people visited the event.

At this exhibition, Exit Professor presented on transporter proteins that facilitate the development of therapeutic drugs for central nervous system diseases. Focusing on drug delivery across the blood-brain barrier, which blocks substances such as therapeutic drugs, the newly developed PICK method was used to elucidate some of the proteins related to transporters that play previously unknown roles in drug transport. This will greatly contribute to drug delivery to the brain. The results of this research are expected to facilitate the development of drugs and drug delivery systems for the treatment of central disorders such as Alzheimer's disease and Parkinson's disease.
Otani Professor presented on topical care products useful for radiation protection. Concerns and awareness about radiation exposure have continued after the nuclear accident. In particular, radiation-related issues are seen not only among the general public but also among forestry and agricultural workers, medical personnel, and nuclear power plant workers, all of whom require protection appropriate to their radiation levels. We presented our skin protection business, which includes creams, powders, and sheets containing barium sulfate, which has radiation shielding effects, and which was conceived while conducting research on public exposure by patients after nuclear medicine treatment and on the effects of exposure and protection for radiation medical workers from the perspective of radiation treatment.

We hope that our participation in this exhibition will lead to the development of research and the social implementation of seeds. Our university will continue to actively develop the intellectual property we possess and give back to society.
