Global analysis of miRNA expression profile during Mycobacterium tuberculosis infection of human primary dendritic cells


ABSTRACT: Mycobacterium tuberculosis (Mtb) is one of the most successful pathogens in human history and remains the second leading cause of death from an infectious agent worldwide. The major reason of Mtb success principally relies on its ability to perfectly adapt to the host, by establishing latent infection and evading from the control driven by immune system. Accordingly, both innate and adaptive immune responses are required to control TB progression and pathogenesis and in particular dendritic cells (DC), as professional antigen presenting cells, are one of the major cellular effectors of the anti-mycobacterial response. In this context, we performed a microarray analysis to characterize the de-regulation of cellular miRNAs during Mtb infection of human DC. Human DC were prepared from human peripheral blood mononuclear cells of anonymous healthy blood donors and infected with Mtb for 3, 8 and 24 hours. This data set contains the global miRNA expression profiling in uninfected and Mtb-infected DC cultures to identify altered signature of miRNAs potentially implicated in Mtb-mediated immune evasion strategies.
