About the Scientist

Patel researches next generation solutions for emerging infectious diseases, including DNA vaccines and DNA-encoded monoclonal antibodies.

Patel holds a B.Sc. in microbiology & immunology from McGill University, Canada, an M.Sc. in Medical Microbiology from London School of Hygiene & Tropical Medicine, University of London, U.K., and a Ph.D. in medical microbiology from the University of Manitoba, Canada.  She received postdoctoral training at the San Raffaele Telethon Institute for Gene Therapy, Milan, Italy and at the University of Pennsylvania/The Wistar Institute. She was promoted to research assistant professor at The Wistar Institute Vaccine & Immunotherapy Center and was named Caspar Wistar Fellow in 2020.

The Patel Laboratory

The Patel laboratory focuses on vaccine and immunotherapy development against emerging infectious diseases, including study of immune mechanisms that contribute to protection from pathogens. Research in the lab employs non-viral DNA vectors for vaccine and antibody delivery. Patel’s most recent studies include DNA vaccine development against Ebola virus, Middle East respiratory syndrome coronavirus (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and multiple studies in the rapidly advancing field of DNA-encoded monoclonal antibodies (DMAbs). Her preclinical animal studies have led to the successful clinical translation of anti-Ebola virus GP DNA vaccine and anti-Zika virus DMAb candidates (NCT03831503). Patel is part of a team at the Wistar Vaccine & Immunotherapy Center leading preclinical immunological studies of a SARS-CoV-2/COVID-19 DNA vaccine candidate. This vaccine candidate entered the clinic in about 10 weeks from vaccine design to FDA approval and trial initiation (NCT04336410 and NCT04447781).

Research

DNA VACCINE DEVELOPMENT AGAINST EMERGING INFECTIOUS DISEASES

Patel’s most recent studies include DNA vaccine development against Ebola virus, Middle East respiratory syndrome coronavirus (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease. Emerging respiratory pathogens including influenza A/B viruses and seasonal coronaviruses, as well as antimicrobial-resistant bacteria are also of interest. In addition to vaccine development, the lab studies potential correlates of protection (antibodies and T cells) in non-human primate samples to improve vaccine development and efficacy and bridge results from animal studies with human clinical data.

DNA-ENCODED MONOCLONAL ANTIBODY (DMAB) DELIVERY AGAINST INFECTIOUS DISEASES

Nucleic acid gene-encoded antibodies are a rapidly advancing field. Patel’s preclinical animal studies have led to the successful clinical translation of an anti-Zika virus DMAb candidate (NCT03831503). The lab’s research interests include approaches to improve DMAb protective efficacy through sequence engineering and strategies for effector function/immune cell recruitment. This includes understanding ways to modulate the early innate immune responses against DNA vectors to improve long-term duration in vivo. These studies could have interesting implications for both infectious diseases antibody delivery as well as different gene therapy approaches.
