Subash Sad

Dr. Subash Sad is a Full Professor specializing in Biochemistry, Microbiology, and Immunology. His research focuses on mechanisms of inflammation and immune system regulation, particularly necroptosis—a form of programmed cell death. His laboratory investigates how macrophage necroptosis contributes to chronic inflammatory diseases like sepsis, cystic fibrosis, and gut inflammation. Current projects include evaluating the role of interferon signaling in necroptosis, mechanisms of pulmonary exacerbations in cystic fibrosis, and the transcription factor FoxO3a's impact on intestinal inflammation.

Research methodologies involve cell biological and genomic approaches, including recombinant pathogen engineering, knockout mice models, and in vivo/in vitro functional assays. Key findings include identifying interferon as a critical upstream regulator of necroptosis and linking FoxO3a to glutaminolysis control in T cells. Dr. Sad's work bridges basic immunology with translational applications, targeting therapies for inflammatory diseases.

Recent publications emphasize bacterial pathogenesis (e.g., Salmonella, Pseudomonas), NK cell metabolism, and inflammasome regulation. These studies underscore the interplay between cellular metabolism, immune signaling, and disease progression. Ongoing projects aim to develop novel therapeutic strategies by modulating necroptosis pathways and understanding host-pathogen interactions in chronic infections.

His research has implications for treating sepsis, cystic fibrosis exacerbations, and intestinal inflammation. Collaborative efforts focus on translating mechanistic insights into clinical applications, such as bacteriophage therapy and immune-based interventions.
