title: Influence of alcohol and gender on immune response.
abstract: Decades of research have shown that women's and men's immune systems function differently. During the reproductive years, women have a stronger immune response than men. This gender difference is believed to be controlled by differences in the blood levels of gonadal steroid hormones--including the female hormone, estrogen, which stimulates immune responses, and the male hormone, testosterone, which is immunosuppressive. In both males and females, alcohol exposure suppresses immune responses; however, it is unclear whether there are significant gender differences in this suppression. Chronic exposure to alcohol alters the production of this same set of hormones (i.e., estrogen and testosterone), and hence alcohol's effects on immunity could involve an indirect mechanism in which alcohol alters hormone levels and, in turn, the hormones regulate immune responses. This article discusses evidence that these hormonal changes play a role in the regulation of the immune response following alcohol exposure in males and females. In addition, the article considers the possible reasons why it takes less time and lower doses of alcohol exposure to cause liver damage in females than in males.
