CCR6 and tuberculosis: DNA methylation levels over both −1194 (61.7 ± 15.4 versus 68.5 ± 11.3%, p = 0.036, Figure 4c) and −1188 (49.9 ± 13.3 versus 57.1 ± 9.9%, p = 0.03) CpG sites of the RASGRP4 gene as well as over +744 CpG site (72.1 ± 13.3 versus 77.8 ± 8.8%, p = 0.035, Figure 4d) of the CCR6 gene were reduced after 6-month anti-TB treatment versus that at diagnosis.
