Inducing Phase Transition in Viral Condensates. A Novel Antiviral Strategy
Dr. Ralf Altmeyer, CEO of Medusa Therapeutics Limited, graduated from University of Tubingen in Germany and did his PhD and postdoctoral training at Institut Pasteur Paris. His scientific career focuses on pathogen-host interactions and development of innovative drugs. He directed the Hong Kong University – Pasteur Research Centre (2003-2006), CombinatoRx-Singapore (2006-2009), Institut Pasteur Shanghai – Chinese Academy of Sciences (2010-2014) and the Helmholtz International Lab at Shandong University (2015-2019). Using approved drug repurposing his team identified suramin as an entry inhibitor of EV-A71 (Ren, 2014, EMI; Ren, 2017 SciRep), the causative agent of Hand Foot Mouth Disease in children. Suramin is currently in clinical development in China. More recently his team worked on RSV, the leading cause of pneumonia in children. His team identified the transcription factor M2-1 as a target for therapeutic intervention (Bailly, 2016, SciRep) leading to the recent discovery that RSV inclusion bodies are LLPS biomolecular condensates which can be hardened by small molecules resulting in reduction of virus in the lungs of infected animals (Risso-Ballester, 2021, Nature). This study provided proof of concept that viral condensates can be targeted by drug-like small molecules for the development of fast-acting therapeutics against acute viral infections.

Explore Viral Infection to Probe Roles of Protein Deamidation
Pinghui Feng is currently a Professor and the Chair of the Section of Infection and Immunity, Herman Ostrow School of Dentistry, Norris Comprehensive Cancer Center of University of Southern California. Pinghui obtained his BS from Hunan Normal University, MS from Wuhan Institute of Virology, and PhD from University of Missouri-Kansas City. Before joining University of Southern California, he received postdoctoral training from Dr. Jae Jung’s laboratory at Harvard Medical School and established his independent research group at UT Southwestern Medical Center as the Virginia Murchison Linthicum scholar in Medical Research. Pinghui is a recipient of Sustaining Outstanding Achievement in Research award (R35) from NIH.
Pinghui’s group has outstanding interest in viral immune evasion strategy, particularly those of human herpesviruses. His lab has discovered that herpesviruses deploy protein deamidation to inactivate innate immune defense. This discovery led to the endeavor to probe the general roles of protein deamidation in fundamental biological processes, such as protein nuclear transport, transcriptional regulation and metabolic reprogramming, in addition to immune defense. Protein deamidation is catalyzed by cellular metabolic enzymes known as glutamine amidotransferases, thus forging potential link between cellular metabolism and other key biological processes. Research in the Feng laboratory was supported by generous startup funds from University of Southern California and grants from private foundations and federal agencies. Pinghui is an Associate Editor for PLoS Pathogens and an editorial member for Journal of Virology. He is a standing member of the advisory committee of International Herpesvirus Workshop and International Workshop on KSHV and Related Agents.

The COVID-19 Pandemic: A View from the Bench
Dr. J. Victor Garcia-Martinez, University of North Carolina, Chapel Hill, uses humanized mouse models, including recently developed humanized-lung mice, to study the pathogenesis of human-specific viruses and therapeutic interventions. Dr. Garcia is using these models to study an array of human respiratory pathogens including RSV, CMV, influenza, MERS, SARS, SARS-CoV-2 and tuberculosis. He has trained over 13 PhD students 40 postdoctoral fellows (past and present). His trainees hold positions in industry, government and academic institutions. Dr. Garcia is a Fellow of the American Academy of Microbiology and his contributions to Inclusion and Diversity have been recognized by the American Academy of Microbiology and the American Society for Cell Biology. Dr. Garcia is also the Director of the International Center for the Advancement of Translational Science.Throughout evolution, humans have been challenged by viral pathogens new to the species. The immune system mounts an adequate response that protects us from the fatal consequences of infection. However, in some instances viruses can circumvent the immune system and cause fatal diseases such as cancer (EBV, KSHV, HCV), hemorrhagic fever (Ebola virus), AIDS (HIV) and pandemics (Influenza, SARS, MERS, SARS-CoV-2). Understanding the host pathogen relationship at a cellular level provides rational approaches to therapy and vaccine development. It also provides a better understanding of human biology and immunology. Dr. Garcia is interested in how human viruses cause human cancer, how HIV causes AIDS and why the immune system is not able to control viral infections and how coronaviruses cause disease in humans. His working hypothesis is that specific viral genes are the key determinants of viral pathogenesis and are responsible for disease progression. To evaluate the role of these genes in disease progression, he has developed in vivo models that recapitulate specific aspects of viral infection. His emphasis has been placed on precision animal models where human specific pathogens can be studied and where novel therapeutic interventions can be evaluated.

Out of the Box: 20 Years of Targeting Virus Infections Unconventionally
Marco Vignuzzi’s lab at the Institut Pasteur, founded in 2008, has carved its own niche between the fields of virology and evolutionary sciences. They have since become a mix of experimental evolution lab and computational group. They focus their attention on medically relevant RNA viruses. Their study models include several picornaviruses (EVA71, EVD68, polio, Coxsackievirus, rhinovirus); the alphaviruses (chikungunya, O’nyong’nyong, Sindbis, Mayaro); the flaviviruses (Zika, dengue, West Nile, yellow fever, Usutu); influenza A virus and Coronavirus-SARS-2. They study the population dynamics and evolution of these viruses in animal models (mostly lab mice and wild mosquitoes, but also Zebrafish and Drosophila). They have partnerships with labs in every tropical region of the world with whom they tackle projects in field settings. The lab develops new tools in data visualization and multi-dimensional scaling to study virus infection in lab and clinical settings. Finally, they combine experimental evolution and computation to generate new antiviral approaches that are of interest to both public health and industry.
