Conversely, the increased expression of interferon inducible dyamin MX2 at day 14 and cytokine receptors IL22RA2 and XCR1 at day 42 post infection, and decreased expression of T-cell regulator TNFSF18 at day 14- and TLR5, defensin DEFB5 and V-ATPase subunit gene ATP6V0D2 at day 42- post infection, distinguished M. tuberculosis H37Rv infected from M. bovis AF2122/97 infected animals upon PPD-B stimulation. This evidence concerns the gene TNFSF18 and infection.
