IDRI Makes Strides in Vaccine Technology, New Study in Science Translational Medicine Reports





SEATTLE, July 27, 2011 /PRNewswire-USNewswire/ -- The Infectious Disease Research Institute (IDRI), International Centre for Genetic Engineering and Biotechnology (ICGEB) and Imdaptive Inc. announce new research that for the first time shows how to define how vaccine components expand immune responses. The results of these studies are published in Science Translational Medicine today.

The research was performed by scientists at IDRI in collaboration with researchers at ICGEB, New Delhi, and Imdaptive, Inc., Seattle. They demonstrated that increased variable chain sequences are observed in animals treated with a recombinant malaria vaccine formulated with immune response enhancers, TLR-agonists, versus animals receiving control vaccines. This diversity, or "antibody repertoire," may have the most significant impact on the vaccine's efficacy against a target pathogen as well as related variants.

Dr. Chetan Chitnis, Principal Investigator, ICGEB, comments, "TLR-agonists developed by IDRI may help malaria vaccines overcome the problem of diversity of malaria parasite strains."

Furthermore, the implications of these findings may impact vaccine formulations for diseases in addition to malaria, such as influenza and HIV.

Dr. Darrick Carter, Vice President of Adjuvant Technology at IDRI and one of the study's Principal Investigators, explains, "By measuring the entire antibody variable repertoire, we are able to show that antibody diversity is a function of the adjuvants used to initiate and enhance the immune response. This knowledge has the potential to make a significant impact on the future of vaccine design."

Dr Steven Wiley, founder of Imdaptive Inc., adds, "This paper demonstrates the usefulness of state of the art sequencing technologies and bioinformatic analysis in order to better understand the immune response at the molecular level".

About IDRI's Adjuvants

Adjuvants are compounds used to improve the body's immune response to vaccines. Adjuvant technology is proving invaluable in the development of vaccines for serious diseases for which vaccines are not currently available, including malaria and HIV.

Adjuvants are a key research component of IDRI's malaria, tuberculosis, leishmaniasis and leprosy vaccine development programs—supported by the Bill and Melinda Gates Foundation, the National Institutes of Health, and the American Leprosy Missions.
