Abstract:
:The action of trehalose-6, 6'-dimycolate (cord factor) of Mycobacterium tuberculosis to induce site II-specific inhibition of mitochondrial oxidative phosphorylation and to stimulate adenosine triphosphatase activity was neutralized by its specific antibody. The activity was restored after dissociation of cord factor from the immune complex.
