“Investigating the protective effects of M. bovis BCG therapy against dementia in a mouse model of Tauopathy”

 

Somnath Shee, PhD
Postdoctoral Fellow
Laboratory of Dr. William Bishai
Center for Tuberculosis Research
Johns Hopkins University, School of Medicine

I earned my PhD (2022) in “Molecular pathogenesis of Mycobacterium tuberculosis” from Dr. Amit Singh’s laboratory, Indian Institute of Science, Bangalore, India. During my graduate program, (1) I utilized high-throughput technologies (transposon mutagenesis, FACS, and Illumina sequencing) combined with a redox-biosensor tool to identify the complete genomic requirement of Mycobacterium tuberculosis (Mtb) for maintaining basal redox homeostasis. Disrupting this homeostasis increased bacterial susceptibility to antibiotics and host stress (PMID: 37642294); (2) I described a novel Mtb response to moxifloxacin (a key drug for MDR-TB). Unlike non-pathogenic E. coli, Mtb reduced respiration when challenged with moxifloxacin. Notably, N-acetyl cysteine (NAC) restored respiration, enhanced ROS production, increased drug lethality, and limited resistance emergence in mice (PMID: 35975988). This work highlights NAC’s potential to enhance fluoroquinolone efficacy.

My postdoctoral research (2022-present) in Prof. Bishai’s laboratory is to discover molecular mechanisms that unify major determinants of Tuberculosis (TB) disease (malnutrition, smoking, aging, among others). We identified a signature of senescent myeloid cells in the lung from TB-susceptible mouse models that form human-like necrotic granulomas. Currently, we are working to repurpose senolytics as host-directed therapy to target TB.

In addition to this project, I am actively involved in developing mycobacteria-based preventive therapy for Alzheimer’s disease (AD). I’ll discuss the major findings of this research in this TRAC seminar.

“The biology and ontogeny of alveolar macrophages across the age spectrum”

Larry Schlesinger, MD
Professor, President and CEO
Texas Biomedical Research Institute
Principal Investigator, Interdisciplinary NexGen TB Research Advancement Center (IN-TRAC)

Larry S. Schlesinger, MD became Professor, President and CEO of Texas Biomedical Research Institute in San Antonio, TX in 2017 and is leading a transformational process focused on scientific growth and cultural change, a new campus master plan and new research and education programs. He is a leading physician scientist whose research program focuses on how the lung environment shapes alveolar macrophage biology in the context of the pathogenesis of tuberculosis and diseases caused by other intracellular pathogens that subvert lung immune mechanisms. He translates these discoveries into new platforms and assays for host-directed therapies for infectious diseases. He has authored 260 peer-reviewed articles and reviews, served as editor of 2 books and has written several chapters in leading textbooks. He has been continually funded by the NIH and other federal agencies as well as private foundations such as the BMGF for more than 35 years. He has trained ~ 180 individuals and led NIH-funded training programs, including the Ohio State University MSTP 2011-2017. He is a past NIH NIAID Council member and Fellow of the AAAS, IDSA, AAP and AAM.
