Gene Expression Profiling in Human Brain Microvascular Endothelial Cells in Response to Treponema pallidum Subspecies pallidum
Abstract Neurosyphilis (NS) is a neurological disorder caused by Treponema pallidum subspecies pallidum (T. pallidum), but how T. pallidum attach to and cross the blood−brain barrier (BBB) and how BBB response to this bacteria remain unclear. To explore how the human brain microvascular endothelial cells (HBMECs) response to T. pallidum, the Agilent SurePrint G3 Human Gene Expression 8×60K microarray was used. The results revealed that 249 genes were differentially expressed in HBMECs infected with T. pallidum. In particular, genes encoding proteins involved in bacterial adhesion, endothelial cell activation and immune response were regulated by T. pallidum. Furthermore, Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed to determine the biological functions of differentially expressed genes. In summary, T. pallidum changes the gene expression profile in HBMECs, and differentially expressed genes are associated with widespread biological and pathophysiological functions. Above all, this is the first paper reporting the effects of T. pallidum on HBMECs. These data develop a new platform for further molecular experiments on the pathogenesis of NS.
