Genome-wide microRNAs analysis of peripheral blood mononuclear cells reveals elevated miR-142-3p expression as a potential biomarker for secondary syphilis

Project description:Treponema pallidum subspecies pallidum (T. pallidum) infection induces significant immune responses, resulting in tissue damage. Gene expression plays an essential role in regulating the progression of syphilis infection. However, little is known about the regulatory role of miRNAs in the immune response to T. pallidum infection. Here, we analyze the differential expression of miRNAs in peripheral blood mononuclear cells (PBMCs) between secondary syphilis (SS) patients and healthy controls and study the correlation between miRNAs expression and clinical features with bioinformatics.

MicroRNA expression profiling of peripheral blood mononuclear cells associated with syphilis

Project description:Treponema pallidum (Tp) infection evokes vigorous immune responses, resulting in tissue damage. The immune mechanism after Treponema pallidum infection is still not clear. MicroRNAs (miRNAs) have been shown, however, to influence immune cell function and consequently the generation of antibody responses during other microbe infections, but these values are unknown for Tp. In this study, we performed a comprehensive analysis of differentially expressed miRNAs in healthy persons, untreated patients with syphilis, patients in the serofast state, and serologically cured patients. MiRNAs were profiled from patient peripheral blood obtained at the time of serological diagnosis. There were 89 differentially regulated miRNA identified in total. Then both the target sequence analysis on these different miRNAs and pathway analysis were performed to identify important immune and cell signaling pathways. Following RT-qPCR confirmation, three miRNAs (hsa-miR-195-5p, hsa-miR-223-3p, hsa-miR-589-3p) showed significant difference among serofast state, and serological cure (P<0.05). Two miRNAs (hsa-miR-195-5p, hsa-miR-1204) showed significant differences among untreated patients and healthy individuals. This is the first study of miRNA expression difference in PBMC in different stages of T. pallium infection. Our study suggests that the combination of three miRNAs has great potential to serve as non-invasive biomarkers of Treponema pallidum infections, which will facilitate better diagnosis and treat of T. pallium infections.

miRNA expression of exosomes from Treponema pallidum-stimulated macrophages

Project description:We performed a comprehensive miRNA profiling analysis of exosomes by Treponema pallidum-stimulated microarrays. A total of 2×106 macrophages were obtained by THP-1 differentiation and grown in RPMI-1640 containing 10% exosome-free FBS. Exosomes were acquired from macrophage culture supernatants with (n = 7) or without (n = 3) T. pallidum. Briefly, macrophages were washed in PBS twice and further grown in fresh medium for 12 h (n = 2), 24 h (n = 2) and 48 h (n = 3) to collect exosomes. Exosomal miRNA microarray assays were carried out with Agilent Human miRNA (8*60K) array.

Lysinoalanine crosslinking is a conserved post-translational modification in the spirochete flagellar hookLysinoalanine crosslinking is a conserved post-translational modification in the spirochete flagellar hook

Project description:In this project, we investigated whether diverse spirochete species contain lysinoalanine cross-linkages between conserved residues in their flagellar hook proteins (FlgE). We examined the following species: Treponema denticola¸ Borreliella burgdorferi, Treponema phagedenis, Treponema pallidum, Brachyspira hyodysenteriae, Leptospira interrogans. For each bacterial species, we examined a variety of different sample types, including recombinantly produced FlgE, polyhooks purified from flik knock-out strains, and wild-type periplasmic filaments. Overall, our data suggests that lysinoalanine crosslinking in a conserved FlgE post-translational modification in spirochetes and is required for the unique motility of these organisms.
