Interview With a Scientist—Elhanan Borenstein: Metagenomics Systems Biology

Cataloging the human microbiome—the complete collection of bacteria, fungi, archaea, protists, and viruses that live in and on our bodies—is an enormous task. Most estimates put the number of organisms who call us home on par with the number of our own cells. Imagine trying to figure out how the billions of critters influence each other and, ultimately, impact our health. Elhanan Borenstein, a computer scientist-cum-genomicist at the University of Washington, and his team are not only tackling this difficult challenge, they are also trying to obtain a systems-level understanding of the collective effect of all of the genes, proteins, and metabolites produced by the numerous species within the microbiome.

Interview With a Scientist: Andrew Goodman, Separating Causation and Correlation in the Microbiome

You’ve likely heard some variation of the statistic that there are at least as many microbial cells in our body as human cells. You may have also heard that the microscopic bugs that live in our guts, on our skins, and every crevice they can find, collectively referred to as the human microbiome, are implicated in human health. But do these bacteria, fungi, archaea, protists, and viruses cause disease, or are the specific populations of microbes inside us a result of our state of health? That’s the question that drives the research in the lab of Andrew Goodman, associate professor of microbial pathogenesis at Yale University.

Interview with a Scientist: Michael Summers, Using Nuclear Magnetic Resonance to Study HIV

by

For more than 30 years, NIGMS has supported the structural characterization of human immunodeficiency virus (HIV) enzymes and viral proteins. This support has been instrumental in the development of crucial drugs for antiretroviral therapy such as protease inhibitors. NIGMS continues to support further characterization of viral proteins as well as cellular and viral complexes. These complexes represent the fundamental interactions between the virus and its host target cell and, as such, represent potential new targets for therapeutic development.

In this third in a series of three video interviews with NIGMS-funded researchers probing the structure of HIV, Michael Summers, professor of biochemistry at the University of Maryland, Baltimore County, discusses his use of nuclear magnetic resonance (NMR) technology to study HIV. Of recent interest to Summers has been using NMR to investigate how HIV’s RNA enables the virus to reproduce. His goals for this line of research are to develop treatments against HIV as well as learning how to best engineer viruses to deliver helpful therapies to individuals with a variety of diseases.

In this second in a series of three video interviews with NIGMS-funded researchers probing the structure of HIV, Wes Sundquist, professor of biochemistry at the University of Utah, discusses his lab’s studies of how HIV uses factors in host cells to replicate itself. In particular, Sundquist focuses on the ESCORT pathway that enables HIV to leave infected cells and spread infection elsewhere.
