The study titled, Combustible and electronic cigarette exposures increase ace2 activity and SARS-CoV-2 spike binding, tested the hypothesis that the use of combustible tobacco and non-combustible nicotine products, could affect ACE2 activity and subsequent SARS-CoV-2 infection. The research team found that sACE2 activity was significantly higher in bronchoalveolar lavage fluid from both smokers and vapers compared to non-smokers of the same age. Exposure to cigarette smoke led to increased (...)
