Mean pg/ml ± SD of cytokines in culture supernatants of 48 hr <i>M.leprae</i> stimulated PBMC from 10 each of tuberculoid (BT) and lepromatous leprosy (LL) patients investigated for gene expression studies.

Leprosy patients were typed as per Ridley Jopling classification [1]. p<0.01, p<0.001, p<0.0001 by two tailed Mann Whitney test. P<0.05 was considered significant. Figures in parenthesis ( ) indicate number of patients, [ ] range in pg/ml. [0] below detectable level. # IFN-γ levels reflecting culture supernatants of patients investigated for both qPCR and Flow cytometry analysis is given in Figure S1.
