Significantly lower levels of RANTES were measured in the active TB group unstimulated (p = 0.00 and p = 0.00), SufR stimulated (p = 0.00 and p = 0.00) or BCG stimulated (p = 0.00 and p = 0.00) when compared to QFN pos and QFN neg groups, respectively. This evidence concerns the gene CCL5 and tuberculosis.
