Inhibition of macrophage priming by sulfatide from Mycobacterium tuberculosis.


Sulfatide from the outer surface of Mycobacterium tuberculosis blocked priming in cultured human monocytes. Monocytes were primed in vitro with either lipopolysaccharide (LPS) or interferon-gamma. Primed monocytes released increased amounts of superoxide anion (O2-) when stimulated with formyl-methionyl-leucyl-phenylalanine or with phorbol myristate acetate… (More)
