Smoking has long-term effects on the immune system
Like other factors such as age, sex and genetics, smoking has a major impact on immune responses. This is the finding recently made by a team of scientists at the Institut Pasteur using the Milieu Intérieur cohort of 1,000 healthy volunteers, established to understand variability in immune responses. In addition to its short-term impact on immunity, smoking also has long-term consequences. For many years after they have quit the habit, smokers are left with effects on some of their bodies' defense mechanisms acquired while smoking. These findings, which for the first time reveal a long-term memory of the effects of smoking on immunity, were published in the journal Nature.
