Laboratory of Malaria and Vector Research

José M.C. Ribeiro, M.D., Ph.D.

Chief, Vector Biology Section

Dr. Ribeiro received his M.D. from the State University of Rio de Janeiro, and a Ph.D. degree from the Biophysics Institute of the Federal University of Rio de Janeiro. He was an Assistant and Associate Professor at the Harvard School of Public Health and Professor at the Department of Entomology in the University of Arizona before joining the NIAID in 1996. His work focuses on the role of vector saliva in blood feeding by arthropods, where a great diversity of pharmacologically active compounds and new targets for vaccination against vector borne diseases have been uncovered. Dr. Ribeiro has served for many years in the Tropical Diseases Research Program of the WHO (TDR/WHO) and as editor and reviewer for several journals.

Description of Research Program

Research in the Vector Biology Section explores the biochemical and pharmacological diversity found in the salivary glands of blood feeding insects and ticks. Molecular, biochemical and pharmacological approaches are used in our research. Recently we have used vector salivary gland transcriptome analysis to discover new and interesting compounds, and for that reason have developed tools for bioinformatic analysis.

Major areas of investigation include:

  • Discovery of novel anti-clotting, anti-platelet, immunomodulatory and vasodilatory agents
  • Determination of the mode of action of such compounds
  • Expression of novel proteins and peptides with known and unknown function
  • Development of tools for transcriptome annotation

In each of these areas we seek discoveries that improve our basic knowledge of the evolution of the blood feeding behavior, at the same time generating novel compounds that can be of pharmacological use or developed as vaccine targets. Inquiries about predoctoral and postdoctoral fellowships as well as Ph.D. studentships in the NIH Graduate Partnership Program are welcome.
