Profile AI

Yigael Powrie is a biomedical researcher whose work spans inflammatory disease, redox biology, neuroprotection, and advanced imaging technologies. Research integrates cellular and molecular approaches with in vivo models to elucidate how oxidative stress and immune dysregulation drive tissue-specific pathology. Contributions include studies on rheumatoid arthritis, skeletal muscle cachexia, and accelerated ageing phenotypes across organ systems.

Recent publications highlight innovative strategies such as harnessing microbial effectors for macrophage-mediated drug delivery, alongside investigations into mesenchymal stem cell dysfunction in chronic inflammatory states. Work on PTSD-associated fibroblast alterations expands understanding of peripheral tissue conditioning in mental health disorders, underscoring expertise in cell signaling, immunomodulation, and translational disease modeling.

Additional research explores neuroprotective nutraceuticals, zebrafish behavioral toxicology, and improved three-dimensional fluorescence microscopy using virtual reality for precise colocalization analysis. This interdisciplinary portfolio reflects strengths in redox assessment, regenerative biology, and methodological innovation, contributing to therapeutic development and improved mechanistic insight into chronic inflammatory and neurobiological conditions.
