Pratibha Bhalla, Ph.D. Titles and Appointments Instructor School Medical School Department Immunology Biography Pratibha Bhalla, Ph.D., is an Instructor (since January 2024) in the Department of Immunology at UT Southwestern Medical Center. She is a developmental immunologist whose work focuses on understanding the stromal basis of thymic failure in congenital and acquired conditions, and on developing regenerative strategies to rebuild thymic structure and immune function. Dr. Bhalla integrates stromal biology, single-cell genomics, vascular analysis, and organoid engineering to define how mesenchymal, epithelial, and endothelial niches collectively drive thymus development. Her work demonstrated that neural-crest–derived mesenchymal cells are the causal drivers of thymic hypoplasia in 22q11.2 deletion syndrome and that replacing these defective cells can restore normal thymus size and function. She also identified a Sox9⁺ chondrogenic mesenchymal population that further restricts thymic growth in 22q11.2DS, and showed that pharmacologic modulation can suppress these aberrant mesenchymal programs and enhance thymic expansion. Her research additionally extends to FOXN1-associated immunodeficiencies and human thymic tissues. Dr. Bhalla earned her B.S. (Honors) and M.S. in Microbiology from the University of Calcutta, India, followed by a Ph.D. in Chromatin and Transcription Regulation from the CSIR–Centre for Cellular and Molecular Biology (India). She completed her postdoctoral training in Immunology at UT Southwestern. She has authored many publications, including first-author papers in the Journal of Clinical Investigation (JCI), the Journal of Allergy and Clinical Immunology (JACI), the Journal of Human Immunity (JHI), Scientific Reports, Gene, and Frontiers in Immunology. She serves as an Associate Editor for the Journal of Translational Medicine. Her long-term goal is to engineer stromal-competent, regenerable thymus tissues and develop therapeutic strategies that restore immune function in both primary and secondary immunodeficiencies.
