Abstract Sleep regulates immune functions. In this sense, we asked whether shift workers (morning, afternoon or night) vaccinated against hepatitis A would have some humoral and cellular response impairment. Men (18 to 55 years) will be recruited through different forms of media (electronic, newspapers, radio and magazines). The shift workers sleep pattern will be recorded polysomnographically. Subsequently, the volunteers will be underwent vaccination against hepatitis A (2 doses). After the first administration, blood samples will be collected at 30, 60 and 90 days to assess the humoral response in the experimental groups. The hormones prolactina, growth hormone, cortisol, adrenaline and noradrenaline will also be evaluated. Indeed, stimulations in vitro will be conducted to assess the cellular response profile against the vaccination through the production assessment of IL-4, IFNgama, IL-2 and TNFalfa. (AU) | |
