Overall areas of interest

  • Host defense, infection, macrophage biology, mechanosensation, lung injury, repair and fibrosis

Tools and expertise of the lab

  • Bacterial lung infection models (Scheraga et al, JI. 2020)
  • Extracellular matrix-macrophage interaction model systems (Scheraga et al, JI. 2016 and 2020)
  • Define mechanosensitive host defense cells/molecules
  • Human macrophages from infected and lung injury patients (Scheraga et al, JI. 2020)

Examples of collaborators

  • Mitchell Olman – Extracellular matrix-cell interactions, TRPV4
  • Xiaoxia Li – TLR4/IRAK pathways
  • Vidula Vachharajani – sepsis/infectious pathways
  • Christine McDonald – NOD2 and pulmonary infection
  • William Janssen – lung macrophage subset biology

Lab discoveries

  • Identifying the role of TRPV4 in macrophage activation functions (Scheraga et al, JI. 2016 and 2020)
  • Discovered the role of TRPV4 in bacterial clearance and cytokine secretion in P. aeruginosa pneumonia associated lung injury (Scheraga et al, JI. 2020)

How could these discoveries help patients?

  • New therapies for lung injury
  • Better understanding of innate immune cell-extracellular matrix interactions
  • New therapies to change macrophage polarization to repair lung injury

New NIH Grant Awarded to Study Macrophage Signaling in Lung Injury

Dr. Scheraga will use the support to investigate novel signaling mechanisms that control macrophage function and protect the lung during trauma.
