Using Mouse Models to Study the Pathogenesis and Immune Response to Zika Virus: Michael Diamond, MD, PhD

Microbiology-Immunology Seminar Series

 

Although Zika virus (ZIKV) was isolated approximately 70 years ago, few experimental studies had been published prior to 2016. Concomitant with its recent spread to countries in the Western Hemisphere, which was associated with reports of microcephaly, congenital malformations and Guillain-Barré syndrome, the pace of discovery of ZIKV biology has accelerated greatly. Within a short time period, we and others have established useful mouse and non-human primate disease models, and pre-clinical evaluation of therapeutics and vaccines has begun. Unexpectedly, ZIKV exhibits a broad tropism and persistence in body tissues and fluids, which contributes to the clinical manifestations and epidemiology that have been observed during the current epidemic. In this talk, I will focus on studies from my laboratory that generated mouse models of ZIKV infection and pathogenesis during pregnancy as well as in the male reproductive tract. I will cover the effects of gestational age on ZIKV pathogenesis in utero, analysis of tropism, and discuss novel approaches for counter-measures including therapeutic antibodies and vaccines.

Mechanisms and Inhibition of HIV-1 Integration: Alan N. Engelman, PhD

Microbiology-Immunology Seminar Series

AIDS is incurable due to the stable integration of HIV DNA into cellular chromatin. Integrase, the responsible enzyme, is a high value antiviral target. Dr. Engelman`s research has helped uncover the structural basis of HIV DNA integration, as well as the mechanism of action of the clinical integrase inhibitors. He has additionally characterized a new class of integrase inhibitor that unexpectedly inhibits HIV particle maturation.

The Good and the Bad: Two Faces of Microbiota in the Eye: Rachel R. Caspi, PhD

Microbiology-Immunology Seminar Series


The commensal microbiome affects affects immunity and immune mediated disease locally as well as in distal sites. Microbiota can play very different roles in inflammatory disease affecting the eye, depending on the context and the location. Our data suggest that intestinal microbiota can serve as a source of crossreactive antigenic material that activates retina-specific T cells that happen to migrate through the gut, and endow them with the ability to cross the blood-retinal barrier and fuel autoimmune disease in the eye. On the other hand, microbiota on the surface of the eye may play a positive role in local host defense, by tuning immune function in the ocular surface mucosa.

Molecular Mechanisms of Varicella-zoster Virus Pathogenesis: Ann M. Arvin, MD

Patricia A. Spear Colloquium

Microbiology-Immunology Seminar Series

 Varicella-zoster virus (VZV) is an alphaherpesvirus that causes varicella and establishes latency in sensory ganglion neurons; VZV reactivation results in herpes zoster. The formation of polykaryocytes, induced by cell-cell fusion between fully differentiated host cells within the tissue microenvironment, is a hallmark of VZV pathogenesis in skin and ganglia. Analyzing the molecular mechanisms of VZV pathogenesis in the severe combined immunodeficiency mouse (SCID) model reveals the critical role of the glycoproteins gB and gH/gL in this process. VZV pathogenesis also depends on its tropism for T cells to support viral transport to skin, which is promoted by its capacity to trigger the phenotypic remodeling of both naïve and memory T cells.
