Smoking changes adaptive immunity with persistent effects
Nature
There is significant variability in immune response across the population, some of which is related to age, sex, and genetics, but this study examines other factors that may be related to immune response. Notably, the authors found that smoking affected both innate and adaptive immune response, and that the associations were consistent across number of years smoking and number of cigarettes. The effect on innate immune response was short-term, with immune response returning to levels comparable to non-smokers after quitting. The effect on adaptive immunity, however, was long-term and persisted even after quitting — the result of DNA methylation changes. These findings have clinical implications regarding risk of infection, cancer, and autoimmune disease in persons who smoke.
