摘 要:Background:Tuberculosis is a leading cause of death *** is an effective vaccine,but not widely used in many parts of the world due to a variety of *** vaccae(***)is another vaccine used in human subjects to prevent *** the current study,we investigated the potential mechanisms of *** vaccination by determining differentially expressed genes in mice infected with *** before and after *** ***:Three days after exposure to *** H37 Rv strain(5×10~5 CFU),adult BALB/c mice randomly received either *** vaccine(22.5μg)or vehicle via intramuscular injection(n=8).Booster immunization was conducted 14 and 28 days after the primary *** expressed genes were identified by microarray followed by standard bioinformatics ***:*** vaccination provided protection against *** infection(most prominent in the lungs).We identified 2,326 upregulated and 2,221 downregulated genes in vaccinated *** changes could be mapped to a total of 123 signaling pathways(68 upregulated and 55 downregulated).Further analysis pinpointed to the MyD88-dependent TLR signaling pathway and PI3 K-Akt signaling pathway as most likely to be ***:*** vaccine provided good protection in mice against *** infection,via a highly complex set of molecular *** findings may provide clue to guide development of more effective vaccine against tuberculosis.
