New study suggests e-cigarettes impair immune cell function and increase susceptibility to infection

Our case study, "New Study Suggests E-Cigarettes Impair Immune Cell Function and Increase Susceptibility to Infection" exposes the deleterious effects of e-cigarettes on the immune system. 

A recent study involving C57BL/6N and ICR mice supplied by Envigo showed that exposure to e-cigarette aerosol extract (EAE) can alter innate immune responses and increase susceptibility to infection and/or increase infection severity.

  • In a recent in vitro study, which primarily used human neutrophils, exposure to EAE impaired neutrophils' normal function
  • Mouse studies corroborated the in vitro findings; mice neutrophils exposed to EAE were detrimentally affected
  • Overall, these studies suggest that chronic e-cigarette use can alter innate immune responses, which could increase both infection susceptibility and severity
