Yasuo Suzuki
Professor Suzuki graduated from the Shizuoka College of Pharmacy, Graduate School of Pharmacy, acquiring his Ph.D. in 1974. He was appointed as the dean and post graduated dean of the University of Shizuoka, School of Pharmaceutical Sciences on 1996-2002. He served as the vice president of Japanese Society of Carbohydrate Research. He was awarded The Pharmaceutical Society of Japan award 2004 and Chunichi Cultural Award 2004. He occupies a new post as professor in the Life Health Department, specializing in biochemistry, virology and glycobiology with focus on the elucidation of the carbohydrate chain function in viral infections and development of relevant drugs. He is also the Adjunct professor of Griffith University, Australia, and visiting professor of Zhejiang Academy of Medical Science, China. He organized the sialoglycosceince 2006, 5th International conference, Mishima, Japan(Aug.27-30,2006).

Role of Glycans in Microorganism Infection

Regarding diseases of the 21st century, emerging and re-emerging infectious diseases should be noted in addition to metabolic syndrome, cancer, and others. Most pathogenic microbes carry carbohydrate chains on the surface. Many enveloped viruses and some of the non-enveloped viruses express carbohydrate chains. Their carbohydrate chains play important roles in escaping from host immune systems and invading the host. Some microbes and viruses utilize the carbohydrate chains of the host cells for infection. In this case, they are using their carbohydrate-recognizing proteins; lectins or lectin-like molecules which tend to be called by other names, such as hemagglutinins, adhesins and toxins.

Biological recognition systems involving carbohydrate interactions may have contributed significantly to the evolution of the interaction process between viruses/microbes and host animals. This means that study based on the glycomicrobiology is indispensable in the battle against infectious diseases. This site contains comprehensive studies on carbohydrate-related science regarding viruses, bacteria, protozoa, molds, and other microbes. The authors welcome informed reviews and opinions on the research and study of glycomicrobiology.

Threat of Emerging and Reemerging Infectious Diseases in the New Millennium

Many people were convinced that remarkable medical advances would eliminate the various human infectious diseases caused by viruses, bacteria, fungi and protozoa from the world by the end of the 20th century. However, the threats of emerging and reemerging infectious diseases have increased year by year over the past two decades. Researchers have suggested the following reasons for this.

  • Large-scale deforestation in tropical regions has increased the opportunities for human beings to encounter infectious organisms which were previously unknown.
  • Global warming is changing the weather of the temperate zone, and these changes generate infestation by vector insects including mosquitoes and flies.
  • Massive air transportation made possible an ever-increasing movement of people, spreading infectious organisms throughout the world.

The SARS epidemic emerged in 2003 and now the world faces the significant problem of an avian flu pandemic. In the current fight against emerging and reemerging infectious disease, we expect glycomicrobiology to contribute greatly to the research. Clarifying the role of glycans in infectious diseases will provide key information in meeting the difficult challenges that lie ahead.
