Speakers

  • Washington University School of Medicine Brian DeBosch

    Biography

    Brian DeBosch is an Associate Professor of Cell Biology & Physiology and Pediatrics at Washington University, Director of the Washington University Nutrition & Obesity Center Enrichment Program, and Director of the Washington University School Digestive Diseases Research Core Center (DDRCC) Section on Metabolic Homeostasis, Nutrient Transport, and Enterohepatic Signaling.

    Research

    During post-doctoral and early junior faculty epochs, he identified a novel, tractable therapeutic target (hepatic Glucose Transporter 8 (GLUT8)), against non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) pathogenesis. He then defined the mechanism of action of the disaccharide trehalose as a novel glucose transporter inhibitor that recapitulates the effects of GLUT8 deletion in protecting against NAFLD and T2DM by inducing hepatocyte fasting-like responses. He and his team now seek to (i) translate our provocative initial basic discovery to advance human health and longevity; and (ii) define new pathways downstream of glucose transporter signaling so that we can also target these pathways to improve human health.

  • McMaster University Department of Chemical Engineering Carlos D. M. Filipe

    Biography

    Carlos Filipe joined McMaster University as an Assistant Professor in 2002. Currently is Professor and Chair of the Department of Chemical Engineering.

    Research

    His research focuses on creating solutions that produce lasting, beneficial effects on society. One example is the work on thermal stabilization of vaccines, which is the focus of his presentation for this event. Another example is the development of "Sentinel Wraps". These wraps are printable DNAzyme-based systems that make typical Saran™ films capable of detecting and reporting the presence of pathogenic bacteria in packaged food, enhancing food safety and security. Carlos has been recognized by McMaster University with an Innovator of Distinction award for his strong track record of transferring technology to the industry. Carlos is also an award-winning instructor. He is a recipient of the President\'s Award for Outstanding Contributions to Teaching and Learning (2011) from McMaster University, which is the highest recognition given at McMaster for teaching and learning.

Symposium Report

Participants 231 (in-person and online)


The 24th Trehalose Symposium, the first hybrid symposium for in-person and online participants, was met successfully. The numbers of participants are as follows:
Onsite participants: 59, Online participants: 172


During the discussion session, followed by the presentations, Japanese experts shared their viewpoints on why and how most organisms utilize trehalose over other carbohydrates. At the end of the session, the speakers addressed their prospects and expectations for future research and development while indicating the importance of basic research.

Closing Remarks

Toshiyuki Nishio

(Department of Chemistry and Life Science, College of Bioresource Sciences, Nihon University, Professor / The Japanese Society of Applied Glycoscience, Chairman)

Toshiyuki Nishio (Department of Chemistry and Life Science, College of Bioresource Sciences, Nihon University, Professor / The Japanese Society of Applied Glycoscience, Chairman)First, I would like to thank the six researchers for sharing their findings and Dr. Kikawada for chairing this symposium. I would also like to thank all on-site and online attendees for being part of the Trehalose Symposium. As a carbohydrate researcher, I was intrigued to discover that a single oligosaccharide features diverse functionalities in various applications elaborately presented by the speakers. I recall that trehalose was initially evaluated as a carbohydrate-based ingredient in the food industry, but currently, it is also studied as a material inducing bioactivities. R & D work on beneficial applications of trehalose will progress unlimited to specific fields or industries.
However, research on trehalose-inducing bioactivities should go further than identifying applications or usefulness. In other words, I suggest reevaluating basic research, which identifies the mechanisms behind such applicability and utility at the molecular level. Basic research unveils the true nature of a particular substance and what it does, promoting applied research followed by active implementations in various fields. I cannot stress enough the importance of basic research to discover mechanisms behind physiological effects. 

Last week in Tokyo, some distinguished researchers, represented by Dr. Keiji Kainuma, led the seminars at the 70th-anniversary meeting of the Japanese Society of Applied Glycoscience, of which I serve as the chairman.  Dr. Kainuma’s presentation featured a group photo with acclaimed researchers, including the late Dr. Hidemasa Hidaka, known for fructooligosaccharide research. I noticed the sign "The First Trehalose Symposium” hanging above the celebrated scientists. A sense of pride and appreciation filled my heart through the visual evidence that well-respected researchers were actively engaged with the Trehalose Symposium. Many researchers made presentations from the very first session in 1997 to the latest 24th session. Some discoveries were implemented while others were not. Considering its valuable history, I believe the continuation of the Trehalose Symposium is critical. Although many unknowns are yet to be explored in trehalose research, I encourage all of you to stand on top of the accumulated knowledge from the past 24 sessions while revisiting the valuable ideas and clues from the discussion session one at a time. I sincerely hope the Trehalose Symposium nourishes your future research.

Lastly, I would like to conclude my speech by wishing you all continued success and prosperity. Thank you.
