Vaccines and Other Preventative Strategies

In an effort to advance strategies to prevent infectious diseases, faculty members within the Department of Pediatrics are actively engaged in the development and implementation of a variety of prevention strategies. Their research focuses on developing new vaccines, creating effective topical microbicides (products that can be used topically to prevent the transmission of sexually transmitted infections), and fostering attitudes and developing systems that promote the timely delivery and use of these methods.

Researchers

Bao_Xiayoug
Xiayong Bao PhD| Associate Professor | Department of Pediatrics


Dr. Bao's research interests focus on biological roles of small non-coding RNAs (sncRNAs), especially the newly discovered sncRNA derived from tRNA, in response to viral infection and environmental stimuli. Biological function studies of sncRNAs are a burgeoning field of interdisciplinary research that crosses the path from chemistry, molecular biology, bioinformatics and computer sciences. The ultimate goal of her sncRNA research is to control viral replication or stress-induced cellular responses by regulating the expression of sncRNAs. Her other research interests include identifying the mechanisms associated with immune evasion of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV), the two leading causes of lower respiratory tract infection in children, and developing therapeutic molecules and attenuated vaccine candidates to combat or prevent these two viral infections.

Nigel_Bourne Nigel Bourne PhD| Professor and Senor Scientist | Department of Pediatrics

Dr. Bourne is a Professor in the Department of Pediatrics and a Senior Scientist with the Sealy Center for Vaccine Development. He received his PhD from the University of Wales (Cardiff) Institute of Science and Technology. His research focus for over twenty years has been the development and evaluation of novel vaccines and therapeutics against viral infections with an emphasis on in vivo studies in appropriate small animal models. One of the principal areas of interest has been the development, refinement, and use of mouse and guinea pig models of genital herpes disease to explore the impact of novel vaccines, antiviral agents and topical microbicides. In addition, for the past ten years, he has worked extensively with small animal models of flavivirus diseases, in particular West Nile encephalitis, Japanese encephalitis and Dengue.

 

Richard Pyles Richard Pyles PhD | Professor and Senor Scientist | Department of Pediatrics

Dr. Pyles in a Professor in the Department of Pediatrics and Microbiology & Immunology and co-Director of the UTMB Assay Development Services Division in the Galveston National Lab. He received his B.A. in Biology and Chemistry from Hanover College, Indiana. He received his PhD in Molecular Genetics and Biochemistry & Microbiology from the University of Cincinnati College of Medicine. He completed his postdoctoral fellowship in the Department of Cell Biology, Neurobiology and Anatomy at the University of Cincinnati.  He joined UTMB in 2000 as part of the establishment of the Sealy Center for Vaccine Development.

Dr. Pyles’ research interests focus on the interaction of host mucosae with bacterial communities (microbiome) and pathogens that dramatically impact human health.  His career has been primarily focused on improving women’s health including the study of sexually-transmitted infections. He is currently involved in preclinical and clinical studies of devices and interventions that increase ease of use and efficacy of next generation therapies.  Recent work has led to the establishment of novel systems to study both vaginal and nasal human mucosae after colonization by transplanted microbiome communities.
