A Western blot showed that TB could activate the toll-like receptor (TLR)2/4-mediated myeloid differentiation factor 88 (MyD88)-dependent mitogen activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) signaling pathway and the TLR2-mediated phosphoinositide 3-kinase (PI3K)–AKT signaling pathway, enhancing the immune functions of RAW264.7 macrophages. This evidence concerns the gene AKT1 and tuberculosis.
