Figure 4. High HO-1 expression in the later stage of HIV-1 infection favors TB infection.

Figure 4

A. The relative expression of the HO-1 gene was normalized using GAPDH levels in all study groups. All data are expressed as mean±SEM values. Significant differences are represented as the p value <0.05 (*). B. Represents scatter plot depicting significant positive correlation between HO-1 and FoxP3 gene expression in HIV-1 infected individuals. C. Scatter plot showing no significant correlation between HO-1 and FoxP3 variant 1 & 2 expression in PBMCs of healthy controls. The solid lines represent linear regression of points. Rho and p values are from the Spearman rank correlation test.
