Airway Protein Modifications caused by New and Emerging Tobacco Products as Markers of Exposure and Potential Health Risks

Principal Investigators: Boris Reidel

Funding Mechanism: NIH Grant

Institution: University of North Carolina - Chapel Hill

The use of new and emerging tobacco products (NETPs) such as hookah and e-cigarettes is increasing, particularly by the younger population in the US. The goal of this study is to examine airway protein modifications that result from NETP use. Study aims are: (1) to identify NETP-induced protein modifications in vitro of smoke/vapor-exposed human bronchial epithelial cell (HBEC) surfaces (airway epithelial cells for analysis are routinely received and subsequently maintained by the institution); and (2) to establish protein modifications as markers of NETP use and effects in vivo by conducting mass spectrometry analysis of tobacco product user sputum samples (previously collected from healthy cigarette, e-cigarette and hookah users ages 18-50). Findings will provide new information about the airway toxicity effects of tobacco product use.
