About the Speakers
Dayton Petibone, PhD
Division of Genetic and Molecular Toxicology
National Center for Toxicological Research
U. S. Food and Drug Administration
Dayton Petibone, PhD, is a Research Biologist in the Division of Genetic and Molecular Toxicology at FDA’s National Center for Toxicological Research (NCTR). Dr. Petibone, in collaboration Scientists from the FDA’s Center for Biologics Evaluation and Review, is currently developing in vitro models of ZIKV infection and transmission. Dr. Petibone received his PhD in Applied Bioscience from the University of Arkansas at Little Rock.
Qiang Shi, PhD
Division of Systems Biology
National Center for Toxicological Research
U.S. Food and Drug Administration
Dr. Qiang Shi obtained a PhD in pharmacology from Zhejiang University in China. He completed his postdoctoral training in drug induced liver injury (DILI) at FDA’s National Center for Toxicological Research (NCTR) between 2007 and 2010, when he was then converted to a visiting scientist. Dr. Shi’s main research focus is mechanisms, biomarkers, and models for DILI.
About the Presentation
The Zika virus (ZIKV) may be sexually transmitted and can result in birth defects or fetal loss. The presentation is an evaluation of testicular organoids for use as an in vitro model of ZIKV infection. Once developed, this model might be useful for evaluating potential vaccines or treatments for ZIKV infection in the male reproductive system.
Liver microphysiological systems (MPS) are novel cell culture approaches aimed at maintaining in vitro the main physiological characteristics that these cells present in the liver of live laboratory animals or humans. During this presentation, major commercial liver MPS will be introduced, focusing on how they work and the pros and cons of each platform. The challenges in using liver MPS to help reduce or refine animal tests will also be discussed.
Learning Objectives
- Describe the ways Zika virus is transmitted among the human population and the negative outcomes associated with Zika virus infection.
- Discuss how in vitro testicular organoid models can be used as a model of Zika virus infection.
- Explain the definition of liver microphysiological systems.
- Describe how the major commercial liver microphysiological systems work.
- Discuss the hopes and challenges of using liver microphysiological systems to aid drug discovery and development.
