Cytokine arrays reveal differences in cytokine/chemokine expression patterns of MDM infected with <i>M. tuberculosis</i> W06 or M24 strains.

<p>Human MDM were infected with <i>M. tuberculosis</i> W06 or M24 Beijing strains for 72 h, after which the cell culture supernatants were collected and analyzed for cytokine/chemokine content using a RayBio human cytokine antibody array C series 1000 (a and b). The detection signals were captured with X-ray films (A). The signals on the membranes were quantified by densitometry (B). +, positive control spots; -, negative control spots; 1, GM-CSF; 2, IL-10; 3, IL-1β; 4, IL-6; 5, NAP-2; 6, Rantes; 7, TNF-α; 8, GRO-α; 9, IL-8.
