A previous study showed that EC aerosol increased ACE2 activity and soluble ACE2 levels in EC users’ bronchoalveolar lavage fluid . In the current study, the team also measured ACE2 levels and transmembrane protease, serine 2 protease activity in EpiAirway™ tissues, and the magnitude of SARS-CoV-2 pseudoparticle infection.
Study findings Related StoriesThe authors noted that PG, VG, and nicotine-containing aerosols enhanced the infection of EpiAirway™ tissues by SARS-CoV-2 pseudoparticles in a dose-dependent manner. Notably, benzoic acid provided substantial protection against infection-enhancing effects of PG/VG and nicotine for at least 48 hours after the AL exposure ceased, likely because pH levels returned to normal during this time following vaping.

Frontiers | Mucosal immunity: The missing link in comprehending SARS-CoV-2 infection and transmissionSARS-CoV-2 is primarily an airborne infection of the upper respiratory tract, which on reaching the lungs causes the severe acute respiratory disease, COVID-19. Its first contact with the immune system through the epithelia of the nasal passages and Waldeyer’s ring of tonsils and adenoids induces mucosal immune responses revealed by the production of secretory IgA (SIgA) antibodies in saliva, nasal fluid, tears, and other secretions within 4 days of infection. Evidence is accumulating that these responses might limit the virus to the upper respiratory tract resulting in asymptomatic infection or only mild disease. The injectable systemic vaccines that have been successfully developed to prevent serious disease and its consequences do not induce antibodies in mucosal secretions of naïve subjects, but they may recall SIgA antibody responses in secretions of previously infected subjects, thereby helping to explain enhanced resistance to repeated (breakthrough) infection. While many intranasally administered COVID vaccines have been found to induce potentially protective immune responses in experimental animals such as mice, few have demonstrated similar success in humans. Intranasal vaccines should have advantage over injectable vaccines in inducing SIgA antibodies in upper respiratory and oral secretions that would not only prevent initial acquisition of the virus, but also suppress community spread via aerosols and droplets generated from these secretions.
