ABSTRACT
Circular RNAs (circRNAs) play a vital role in the regulation of Mycobacterium tuberculosis (M.tb) by macrophages. In this project, the potential role of hsa_circ_0001204 in M.tb-infected macrophages is explored. Hsa_circ_0001204 was determined in the patients with tuberculosis (TB) and M.tb-infected macrophages. Its effect on the survival of M.tb and the apoptosis and inflammation of M.tb-infected macrophages was evaluated. Toll-like receptor 4/nuclear factor-κB (TLR4/NF-κB) signalling was detected by western blotting and immunofluorescence. TB patients and M.tb-infected THP-1 cells showed the significant downregulation of hsa_circ_0001204. Upregulating hsa_circ_0001204 reduced M.tb survival and suppressed the apoptosis and inflammatory response of THP-1 cells. The TLR4/NF-κB signalling pathway could be inhibited by hsa_circ_0001204 overexpression, which was activated by M.tb-infection. Hsa_circ_0001204 confers protective effects in M.tb-infected THP-1 cells, at least partly via the inhibition of TLR4/NF-κB signalling pathway.
