Emerging infections are a global public health threat. The Morrison laboratory seeks to improve our knowledge of the molecular pathogenesis of emerging virus infections (i.e., what are the critical host-pathogen interactions that contribute to protection or pathology?) by addressing questions at the interface of immunology and virology. In addition, the Morrison laboratory uses cell culture-based and animal infection models to test novel vaccines, anti-virals and immunomodulatory therapeutics against acute and chronic virus infection. As part of the READDI-AC, we are engaged in target site discovery for antivirals against alphaviruses, testing new antivirals for efficacy against alphavirus infection and disease, and elucidating mechanisms of action for antiviral drugs.

The Heaton Laboratory at Duke University is primarily interested in the study of respiratory RNA viruses.  They have published work on viruses of the families: orthomyxoviridae, paramyxoviridae, and coronaviridae.  Research in the lab leverages several complementary approaches such as high-throughput genomic screening and transgenic animal models in order to understand, and develop new ways to combat, respiratory viral disease.  In the context of the READDI-AC program, the Heaton Laboratory is focused on developing fluorescent assays that report on viral enzymatic activities to help prioritize antiviral compounds that inhibit broad families of viruses and work via novel mechanisms of action.

The Dulin lab at the Vrije Universiteit Amsterdam develops high-end force and fluorescence microscope to interrogate the assembly and the enzymatic activity of biomolecular complexes at the single molecule level and with high spatiotemporal resolution. We have a keen interest in the dynamics of polymerase assembly/elongation and of helicase double-stranded nucleic acid unwinding. Specifically, we aim at understanding how the composition of the replication-transcription complex from, e.g. SARS-CoV-2, regulates viral RNA synthesis. Within the READDI-AC consortium, we work closely with the interdisciplinary team in Core C to reveal the mechanism of action of antiviral drugs targeting the viral polymerase and helicase of several RNA viruses of concern using our state-of-the-art single-molecule approaches.

The Kirchdoerfer lab at the University of Wisconsin-Madison uses a combination of biochemistry and structural biology to study viral proteins with a special focus on coronaviruses. Our expertise ranges from protein expression and purification to high-resolution structure determination using single-particle cryo-electron microscopy. We are particularly interested in multi-subunit viral complexes and their interactions with substrates and small molecules as well as expanding structural biology knowledge beyond SARS-CoV-2. As part of the READDI-AC consortium, we are using our lab’s expertise in viral polymerases and working closely with the multidisciplinary team in Core C to establish primary and secondary assays for viral protein function as well as providing single-particle cryoEM structure information for discovered compounds bound to their viral targets.

Alison Axtman, Ph.D., is a principal investigator in medicinal chemistry at SGC-UNC and Research Associate Professor in the Division of Chemical Biology and Medicinal Chemistry Department in the UNC Eshelman School of Pharmacy. Her interests lie at the interface of chemistry and biology, with a focus on using small molecules to explore and impact disease-propagating biological pathways. One active project is aimed at finding pre-clinical small molecule candidates that address the need for new antiviral therapies. She is eager to enable the efforts of other investigators through sharing high-quality small molecule tools to speed the drug discovery process and more quickly help patients in need.

James C. Sacchettini is a molecular biologist and protein crystallographer at Texas A&M University. He serves as Director of the Texas A&M Center for Structural biology.
