Figure Lengend Snippet: Summary of changes in chemokine and cytokine production by PBMC from Leprosy Patients and Household Contacts upon in vitro culture. The levels of chemokines (CXCL8, CCL2, CXCL9, CCL5, CXCL10) and cytokines (IL-6, TNF, IFN-γ, IL-17, IL-4, IL-10 and IL-2) were measured in the supernatant from in vitro cultured PBMC from leprosy patients (L, n=79), household contacts (HHC, n=91) and endemic controls (EC, n=87). Data were obtained in the absence of exogenous stimuli (Unstimulated Culture) and the presence of M. leprae antigen stimuli (M. leprae-stimulated Culture). Cytometric Beads Array (CBA) performed quantitative analysis of chemokines and cytokines according to manufacturer instructions. (A) Major changes observed in soluble mediators amongst groups were summarized considering the fold changes in concentrations detected in PBMC culture supernatants from HHC and L according to EC (Fold Change in concentration = HHC/EC or L/EC). Log10 of Fold Change values (magnitude) was combined with the -Log10 p values (significance) obtained by Dunn’s post-test for multiple comparisons. (B) Differences in chemokines and cytokines signatures were assessed according to EC (Delta in % = %HHC – %EC). Log10 of Delta values (magnitude) was combined with the -Log10 p values (significance) obtained by Chi-square comparisons. (C) Differences in chemokines and cytokines network correlations were assessed according to EC (Delta in correlation numbers = HHC – EC or L – EC). Delta values (magnitude) were combined with the % of correlations from EC (threshold = decrease or increase > 33%). In all cases, significant decrease ( ), increase ( ), or non-significant changes ( ) are highlighted on each chart distribution.
