Daniel J. Prantner

Daniel J. Prantner serves as an Assistant Professor in the Department of Microbiology and Immunology at the School of Medicine, University of Maryland, where his research centers on innate immune mechanisms in macrophages and sepsis pathogenesis. His work bridges immunology and cellular metabolism to uncover novel regulatory pathways in inflammatory diseases.

His academic foundation includes:

• B.S. in Biology from the University of Wisconsin-Madison
• Ph.D. in Microbiology and Immunology from the University of Arkansas for Medical Sciences under Dr. Uma Nagarajan and Dr. Roger Rank

Dr. Prantner's research program investigates how metabolites like methylglyoxal modulate Toll-like receptor signaling and interferon responses in macrophages, with particular emphasis on sepsis models. His laboratory explores the crosstalk between mitochondrial metabolism and innate immune activation, revealing how metabolic pathways such as HIF-1α and AMPK regulate inflammatory outcomes. This immunometabolism-focused work has significant implications for developing targeted therapies against dysregulated immune responses.

Analysis of his publication record reveals a consistent trajectory toward understanding metabolic control of inflammation, with recent work highlighting methylglyoxal as a key mediator in TLR4/RAGE-independent proinflammatory pathways and AMPK-STING axis in antiviral defense. His research demonstrates increasing sophistication in connecting cellular biochemistry to immune phenotypes.

Key recognitions include:

• F32 Postdoctoral Fellowship for research on host mitochondrial metabolism in immune signaling

Dr. Prantner has secured competitive grant funding including an R21 award characterizing methylglyoxal in murine sepsis models, demonstrating NIH confidence in his innovative approach to immunometabolism. His mentorship occurs within Dr. Stefanie Vogel's research group at the University of Maryland School of Medicine, where he transitioned from postdoctoral fellow (since August 2010) to independent faculty. Ongoing projects continue to dissect metabolic checkpoints in macrophage activation with translational applications for septic shock.

He operates within the Department of Microbiology and Immunology's research ecosystem, collaborating on innate immunity projects that integrate biochemical, genetic, and physiological approaches to model systems.
