MAPK3 and tuberculosis: In our previous work, we have shown the effect of MTB antigen stimulation on the activation of MAPKs-ERK1/2 and P-38 in TB patients and healthy controls, and we found decreased phosphorylation of ERK1/2 and p38 after MTB antigen treatment in TB patients, while only ERK1/2 phosphorylation was inhibited in healthy individuals.
