Newswise — CHAPEL HILL, NC – In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease, including COVID-19.
The findings, published in the American Journal of Respiratory Cell and Molecular Biology, show that vaping changes the expression of genes and production of proteins in respiratory cells, as well as altering virus-specific antibody production.
“In many of the study participants, we observed more changes to the immune response in e-cigarette users than we did in smokers,” said first author Meghan Rebuli, PhD, assistant professor in the UNC Department of Pediatrics and member of the UNC Center for Environmental Medicine, Asthma, and Lung Biology. “All of these factors have the potential to adversely affect response to a virus…
