A multi-omic analysis reveals a regulatory role of CD180 during the response of macrophages to Borrelia burgdorferi [RNA-Seq]

Project description:Macrophages are cells of the innate immune system with the ability to phagocytose and induce a global pattern of responses that depend on several signalling pathways. We have determined the biosignature of murine bone marrow-derived macrophages and human blood monocytes using transcriptomics and proteomics approaches. We identified a common pattern of genes transcriptionally regulated that overall indicate that the response to B. burgdorferi involves the interaction of spirochetal antigens with several inflammatory pathways corresponding to primary (triggered by pattern recognition receptors) and secondary (induced by proinflammatory cytokines) responses. We also show that the Toll-like receptor family member, CD180 is downregulated by the stimulation of macrophages, but not monocytes, with the spirochete. Silencing Cd180 results in increased phagocytosis while tempering the production of the proinflammatory cytokine, TNF. Cd180-silenced cells produced increased levels of Itgam and surface CD11b, suggesting that the regulation of CD180 by the spirochete initiates a cascade that increases the CR3-mediated phagocytosis of the bacterium while repressing the consequent inflammatory response.

Identification of the differences between gene expression in normal human dermal fibroblasts (NHDF cell line) infected with Borrelia burgdorferi sensu lato spirochetes

Project description:The similarity of Lyme borreliosis to other diseases and the complex pathogenesis cause diagnostic and therapeutic difficulties. Changes at the cellular and molecular level after Borrelia sp. infection remain still poorly understood. Therefore, the present study focused on the gene expression in human dermal fibroblasts in differentiation of infection with Borrelia garinii, Borrelia afzelii and Borrelia burgdorferi sensu stricto spirochetes. For microarray analysis 10 samples were used: 3 control samples - K, 2 samples of NHDF cells infected with Borrelia garinii - G, 2 samples of NHDF cells infected with Borrelia afzelii - A and 3 samples of NHDF cells infected with Borrelia burgdorferi sensu stricto - SS.

Borrelia burgdorferi induces a type I interferon response during early stages of disseminated infection in mice

Project description:Background: Lyme borrelia genotypes differ in their capacity to cause disseminated disease. Gene array analysis was employed to profile the host transcriptome induced by Borrelia burgdorferi strains with different capacities for causing disseminated disease in the blood of C3H/HeJ mice during early infection. Results: Borrelia burgdorferi B515, a clinical isolate that causes disseminated infection in mice, differentially regulated 236 transcripts (P<0.05 by ANOVA, with fold change of at least 2). The 216 significantly induced transcripts included IFN-responsive genes and genes involved in immunity and inflammation. In contrast, B. burgdorferi B331, a clinical isolate that causes transient skin infection but does not disseminate in C3H/HeJ mice, stimulated changes in only a few genes (1 induced, 4 repressed). Transcriptional regulation of type I IFN and IFN-related genes was measured by quantitative RT-PCR in mouse skin biopsies collected from the site of infection 24 hours after inoculation with B. burgdorferi. The mean values for transcript of Ifnb, Cxcl10, Gbp1, Ifit1, Ifit3, Irf7, Mx1, and Stat2, were found to be significantly increased in B. burgdorferi strain B515-infected mice relative to the control group. In contrast, transcription of these genes was not significantly changed in response to B. burgdorferi strain B331 or B31-4, a mutant that is unable to disseminate. Conclusions: These results establish a positive association between the disseminating capacity of B. burgdorferi and early type I IFN induction in a murine model of Lyme disease.

Regulation of Borrelia burgdorferi-induced macrophage activity by spirochetal-regulated surface receptors

Project description:Macrophages mediate the elimination of pathogens by phagocytosis resulting in the activation of specific signaling pathways that lead to the production of cytokines, chemokines and other factors. Borrelia burgdorferi, the causative agent of Lyme disease, causes a wide variety of pro-inflammatory symptoms. The proinflammatory capacity of macrophages is intimately related to the internalization of the spirochete. However, most receptors mediating this process are largely unknown. We have applyedapplied a multiomic approach, including the proteomic analysis of B. burgdorferi-containing phagosome-enriched fractions, to identify surface receptors that are involved in the phagocytic capacity of macrophages as well as their inflammatory output. Sucrose gradient protein fractions of human monocyte-derived macrophages exposed to B. burgdorferi contained the phagocytic receptor, CR3/CD14 highlighting the major role played by these proteins in spirochetal phagocytosis. Among others, Other proteins identified proteins include C-type lectins, scavenger receptors or siglecs, and contain uPAR and MARCO. We also identified the Fc gamma receptor pathway as involved both in the phagocytosis of , and TNF induction by B. burgdorferi in the absence of antibodies. The common gamma chain, FcR, mediates the phagocytosis of the spirochete, likely through Fc receptors and C-type lectins, in a process that involves Syk activation. Overall, these findings highlight the complex array of receptors involved in the phagocytic response of macrophages to B. burgdorferi.

Single-cell transcriptome analysis of the early immune response in the lymph nodes of Borrelia burgdorferi-infected mice

Project description:Lyme borreliosis is a disease caused by Borrelia burgdorferi sensu lato bacteria. Borrelia burgdorferi is known to induce prolonged extrafollicular immune responses and abnormal germinal center formation. However, the mechanism behind this is poorly understood. The extrafollicular response is characterized by strong plasmablast induction and by an IgM, IgG3, and IgG2b dominant antibody production. These antibodies do not generate a neutralizing type of immunity, and the bacteria eventually establish a persistent infection. Here, we performed single-cell RNA sequencing to characterize the immune landscape of lymph node lymphocytes in the early Borrelia burgdorferi infection in a murine model.

Epigenomic landscape of Lyme disease spirochetes reveals novel motifs

Project description:Borrelia burgdorferi, the etiological agent of Lyme disease, persists in nature through an enzootic cycle consisting of a vertebrate host and an Ixodes tick vector. The sequence motifs modified by two well-characterized restriction/modification loci of B. burgdorferi type strain B31 were recently described, but the methylation profiles of other Lyme disease Borrelia have not been characterized. Herein, the methylomes of B. burgdorferi type strain B31 and 7 clonal derivatives, along with B. burgdorferi N40, B. burgdorferi 297, B. burgdorferi CA-11, B. afzelii PKo, B. afzelii BO23, and B. garinii PBr, were defined through PacBio SMRT sequencing. This analysis revealed 9 novel sequence motifs methylated by the plasmid-encoded restriction/modification enzymes of these Borrelia strains. Furthermore, while a previous analysis of B. burgdorferi B31 revealed an epigenetic impact of methylation on the global transcriptome, the current data contradict those findings; our analyses of wild-type B. burgdorferi B31 revealed no consistent differences in gene expression among isogenic derivatives lacking one or more restriction/modification enzyme(s).
