Abstract

Background

The 30-kDa antigen (Ag) of Mycobacterium tuberculosis (M. tuberculosis) is a strong inducer of innate and adaptive immune responses in human tuberculosis. The generation of reactive oxygen species (ROS) plays an important role in inflammatory signaling as well as antimicrobial defense.

Materials and Methods

In this study, we investigated the role of ROS in the activation of mitogen-activated protein kinases (MAPKs) and secretion of the CXC chemokine ligand 8 (CXCL8) and CC chemokine ligand 2 (CCL2) by human monocytes stimulated with the 30-kDa Ag of M. tuberculosis H37Rv.

Results

Treatment of human monocytes with the 30-kDa Ag activated rapid superoxide generation. In addition, the 30-kDa Ag activated mRNA and protein expression of CXCL8 and CCL2 in human primary monocytes through nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-dependent ROS generation. Analysis of MAPK activation (extracellular signal-regulated kinase (ERK) 1/2 and p38) showed rapid phosphorylation of both subfamilies in response to the 30-kDa Ag. In addition, 30-kDa-induced MAPK activation was inhibited in a dose-dependent manner by pretreatment with ROS scavengers. Toll-like receptor (TLR) 2 was required for ROS generation, chemokine production, and MAPK activation following stimulation with the 30-kDa Ag. Using highly specific signaling pathway inhibitors, we found that both p38 and ERK1/2 activation are essential for 30-kDa Ag-induced CCL2 but not CXCL8 production in human monocytes.

Conclusion

These results indicate that TLR2–ROS signaling plays a crucial role in the 30-kDa Ag-mediated expression of CXCL8 and CCL2 in human monocytes. In addition, both p38 and ERK1/2 activation are essential for 30-kDa Ag-stimulated CCL2 production by monocytes.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
