Our laboratory is focused on pre-clinical and translational collaborative science projects in asthma and pulmonary arterial hypertension (PAH). Program project and institutional core(s) offer various in vivo models of asthma and PAH. The laboratory is equipped to perform Flexivent airway hyperreactivity analysis, right ventricle systolic pressure measurements, in vivo lung electroporation for transgene expression, and MouseOx Pulse measurements including arterial oxygen saturation, heart rate and breath rate in experimental models. We provide comprehensive analysis of lung inflammation, goblet cell metaplasia, angiogenesis and airway fibrosis in asthma models. In addition, we offer quantification of endothelial remodeling, muscularization of pulmonary arterioles, right ventricle hypertrophy and fibrosis in PAH models. Collaborative flow cytometry-centric research aimed at unraveling vascular mechanisms in asthma and myeloid mechanisms in PAH is also a main focus of our laboratory. We also provide scientific oversight over the LRI Flow Cytometry Core.

In other words ...

We provide pre-clinical testing in experimental models of asthma and pulmonary arterial hypertension and perform collaborative research of how abnormal blood vessels and bone marrow stem cells contribute to lung diseases.

Coming soon.
