The clone 43 cells were treated with various concentrations (25, 75, and 150 mM) of ethanol, acetaldehyde, and acetate for 16 h, washed in PBS, and stimulated with LPS (1 μg/ml) for 16 h. Cytokine determinations were performed simultaneously with the culture supernatants and cell lysates by direct-binding enzyme-linked immunosorbent assay.
Data represent means ± standard errors from three separate experiments.
