Virology Research

Center for Biodefense and Emerging Infectious Diseases (CBEID) research on viruses that cause tropical and emerging infectious diseases, as well as those that can be used as biological weapons, can be divided into arthropod-borne (arboviruses) and rodent-borne viruses, and those that rely on other reservoir hosts including humans. All but the latter groups are zoonotic viruses that utilize wild animals as reservoir hosts, and cause disease in humans and domestic animals following “spillover” of zoonotic cycles, or adaptation to use humans or domestic animals as amplification hosts. The approaches used to study these viral diseases include basic research on viral replication and pathogenesis..

Many CBEID members are also engaged in research involving the biology and ecology of arthropod vectors, and the interrelationships between the vectors, hosts, and viral disease agents they transmit. Epidemiology (including molecular epidemiology) and epizootiology are also focus areas of research. Building on discoveries made in their basic research, many investigators are invested in the development of novel antiviral treatments, and new or improved vaccines for viral diseases. Computational and structural biology approaches employing advanced imaging techniques (such as cryoelectron microscopy in BSL3 containment) are also strengths of our virology research program.

Most of the funding for virology research programs comes from federally-funded investigator-initiated grants from the NIH and Department of Defense. The NIAID-sponsored Center of Excellence for Translational Research at UTMBalso funds the development of postexposure vaccines for filoviruses. Vaccine development is fostered on campus by the UTMB Sealy Center for Vaccine Development. Arthropod- and rodent-borne viruses are collected and studied by the World Reference Center for Emerging Viruses and Arboviruses under the direction of Dr. Robert Tesh.

Some of the viruses under study in the CBEID are classified as biosafety level 4 agents that require special containment in the Galveston National Laboratory (GNL) and/or the Robert E. Shope, MD Laboratory in the John Sealy Pavilion for Infectious Diseases Research (also known as the Shope Laboratory). Additional facilities for virology research include the W. M. Keck Center for Virus Imaging located in the Blocker Medical Research Building, and BSL3 facilities in the GNL, Keiller Building, and Mary Moody Northen Pavilion.

Training of many virology graduate students and postdoctoral fellows is supported by the McLaughlin Fellowship Fund and the Sealy Center for Vaccine Development, as well as the NIH T32 predoctoral training grant on biodefense.

Structural, physical, and quantitative biology are supported by the Sealy Center for Structural Biology and Molecular Biophysics.
