NEW YORK (Reuters Health) - Lab experiments show that cells that line the mouth become more susceptible to infection with HIV (news - web sites) when they're exposed to alcohol.
To investigate, they exposed cells from the lining or epithelium of the mouth obtained from HIV-negative individuals to various concentrations of alcohol, and then to a strain of HIV modified with green fluorescent protein in order to make the detection of infection easier.
Oral epithelial cells exposed to 4% ethanol for 10 minutes showed three- to six-fold greater susceptibility to infection with HIV strain, Zheng's team reports in the Journal of Acquired Immune Deficiency Syndromes.
