Circulating mycobacterial-reactive CD4+ T cells with an immunosuppressive phenotype are higher in active tuberculosis than latent tuberculosis infection.


BACKGROUND Previous studies suggest that control of Mycobacterium tuberculosis infection is compromised by the activity of regulatory T cells, including those that express CD39, an ectonucleotidase with immunosuppressive properties. Here, we examine the role of CD39 on CD4+ T cells reacting to M. tuberculosis antigens. METHODS Cryopreserved PBMC from… (More)
