Research Interests

​According to the World Health Organization, pneumonia is the leading cause of death in children worldwide, killing an estimated 1.4 million children annually – more than AIDS, malaria and tuberculosis combined.  The neonatal lung environment is highly susceptible to pneumonia during respiratory infections.  My graduate research lab has developed a neonatal model to influenza virus and in this model the immune cells consolidate in the lung interstitium rather than entering the airway [1]. This study mimics autopsy sections taken from children who died from respiratory syncytial and influenza A viral infections [2].  By utilizing human bronchial epithelial cells in an in vitro air-liquid interface culture model to mimic the in vivo human bronchial epithelium of adult and neonatal lungs my lab can evaluate the disparities between adult and neonatal lung cells.  Human airway epithelial cells in the air-liquid interface model form pseudostratified layers with tight junctions, cilia and mucin production [3]. Recent studies suggest that human bronchial epithelial cells are multipotent progenitors capable of differentiating into multiple central and peripheral lung cell types [4]. I propose that the capacity of epithelial cell differentiation is altered between the adult and neonatal lung environments; possibly due to alveolarization taking place until approximately eight years of age. Therefore, immunoregulatory cytokines such as TGFβ and Interleukin 10 are constitutively expressed (unpublished work and [5]); I believe that these cytokines alter the bronchial epithelium to be more permissible to influenza viral infections. This research project will be a novel way to compare the adult and neonatal lung, and will offer expansion into other airway diseases such as asthma, bacterial lung infections and respiratory viruses.  My research students will be able to examine epithelial cell development and differentiation using fluorescent microscopy, altered cell signaling by real time PCR for signaling, single immune cell analysis with flow cytometry and secreted cytokine analysis by ELISA.
