Research in Dr. Henderson's laboratory focuses on
From the 5-lipoxygenase products of arachidonic acid metabolism studies, we are trying to determine the role of specific sPLA2s vs. cPLA2 and cysteinyl leukotrienes in the mediation of airway inflammation and remodeling in a mouse asthma model. Functional genomic studies (i.e., microarray and proteomic analyses) are being performed to determine the molecular mechanisms that mediate allergen-induced airway inflammation and remodeling. Research to identify new molecular targets in pulmonary fibrosis involve studies to determine the effect of novel antifibrotic agents on profibrotic gene expression in the airways in a mouse model of PF. These studies represent a focused effort using chemogenomics to identify, develop, and validate small molecule inhibitors of profibrotic gene expression (microarray and proteomic studies) as novel therapies in PF patients. Stem cells (embryonic and adult bone marrow-derived mouse and human cells) will be isolated and manipulated ex vivo in culture prior to in vivo administration in mice with fibrotic lungs. Important goals are to determine if engrafted cells proliferate and repair/regenerate damaged lung tissue. The effect of small molecule inhibitors of key signaling pathways in the airway fibrotic process will also be examined in these studies that may lead to novel therapies for patients with airway injury and fibrosis.
