  1. Human peripheral blood mononuclear cells (PBMC) were cultured for 24 hr in absence or presence of cadmium acetate or mercuric chloride and stimulated either by monoclonal antibodies (mAb: anti-CD3/anti-CD28/anti-CD40) or heat-killed Salmonella enterica serovar Enteritidis (hkSE). Cytokine values were evaluated in cell supernatants using ELISA; r represents Spearman correlation values estimated for each sample. The last raw represents the Spearman correlation between the mean values of IFN-γ and IL-12p70 of all investigated donors.
