Global gene networks in canine peripheral blood mononuclear cells infected with Mycobacterium avium subsp.hominissuis

ABSTRACT: An opportunistic intracellular pathogen Mycobacterium avium subsp. hominissuis, a member of the nontuberculous mycobacteria (NTM) cluster, causes respiratory disease in immunosuppressed hosts. In particular, infected companion dogs are a potential role to transmit the agent to children or immunosuppressed people. The purpose of this study is to investigate a host-M. avium hominissuis interactome in canine PBMCs during the infection.

Global gene networks of canine monocyte-derived macrophages infected with Mycobacterium intracellulare

Project description:An opportunistic intracellular pathogen Mycobacterium intracellulare, a member of the nontuberculous mycobacteria (NTM) cluster, causes respiratory disease in immunosuppressed hosts, including companion dogs. The purpose of this study is to investigate a host-M.intracellulare interactome in canine monocyte-derived macrophages during the infection.

Monocyte responses associate with MAC lung disease

Project description:To understand nontuberculous mycobacterial (NTM) pathogenesis, we evaluated immune responses to Mycobacterium avium (Mav) in asymptomatic individuals with a previous history of M. avium complex lung disease (MACDZ). We analyzed global gene expression in paired Mav-infected and uninfected peripheral blood monocytes from 17 MACDZ and 17 healthy controls.

Comparative genomic hybridizations of Mycobacterium avium isolates obtained from multiple host species

Project description:A comparative genomic approach was used to identify large sequence polymorphisms among Mycobacterium avium isolates obtained from a variety of host species. DNA microarrays were used as a platform for comparing mycobacteria field isolates with the sequenced bovine isolate Mycobacterium avium subsp. paratuberculosis (Map) K10. ORFs were classified as present or divergent based on the relative fluorescent intensities of the experimental samples compared to Map K10 DNA. Map isolates cultured from cattle, bison, sheep, goat, avian, and human sources were hybridized to the Map microarray. Three large deletions were observed in the genomes of four Map isolates obtained from sheep and four clusters of ORFs homologous to sequences in the Mycobacterium avium subsp. avium (Maa) 104 genome were identified as being present in these isolates. One of these clusters encodes glycopeptidolipid biosynthesis enzymes. One of the Map sheep isolates had a genome profile similar to a group of Mycobacterium avium subsp. silvaticum (Mas) isolates which included four independent laboratory stocks of the organism traditionally identified as Maa strain 18. Genome diversity in Map appears to be mostly restricted to large sequence polymorphisms that are often associated with mobile genetic elements. Keywords: Comparative genomic hybridization

Intracellular Iron Accumulation Facilitates Mycobacterial Infection in Old Mouse Macrophages

Project description:Aging has a significant impact on the immune system, leading to a gradual decline in immune function and changes in the body's ability to respond to bacterial infections. Non-tuberculous mycobacteria (NTM), also known as atypical mycobacteria or environmental mycobacteria, are commonly found in soil, water, and various environmental sources. While many NTM species are considered opportunistic pathogens, some can cause significant infections, particularly in individuals with compromised immune systems, such as the elderly. When mycobacteria enter the body, macrophages are among the first immune cells to encounter them, and attempt to engulf mycobacteria through a process called phagocytosis. Some NTM species, including Mycobacterium avium (M.avium) can survive and replicate within macrophages. However, little is known about the interaction between NTM and macrophages in the elderly. In this study, we investigated the mouse bone marrow-derived macrophage (BMMs) response to M. avium serotype 4, one of the main NTM species in patients with pulmonary NTM diseases. Our results demonstrated that old mouse BMMs have an increased level of intracellular iron and are more susceptible to M. avium serotype 4 infection compared to young mouse BMMs. The whole-cell proteomic analysis indicated a dysregulated expression of iron homeostasis-associated proteins in old mouse BMMs regardless of mycobacterial infection. Deferoxamine, an iron chelator, significantly rescued mycobacterial killing and phagolysosome maturation in old mouse BMMs. Therefore, our data indicate that an intracellular iron overload improves NTM survival within macrophages, and suggest a potential application of iron chelating drugs as a host-directed therapy for pulmonary NTM infection in the elderly

Data-dependent acquisition based proteomic analysis of Mycobacterium avium subsp. paratuberculosis ATCC 19698

Project description:Detection of species-specific proteotypic peptides for accurate and easy characterization of infectious non-tuberculous mycobacteria such as Mycobacterium avium subsp. paratuberculosis is essential. Therefore, we conducted an in-depth global proteomic experiment using M. avium subsp. paratuberculosis ATCC 19698 (Map) strain followed by proteome database search and spectral library generation. The lysate was subjected to in-solution proteomic sample preparation and fractionated using an offline C18 StageTip. Each fraction was acquired in technical triplicates using a 180 min data-dependent acquisition (DDA) method in Orbitrap Fusion Tribrid (Thermo Scientific) mass spectrometer. The resulting raw DDA data were searched against the M. avium subsp. paratuberculosis proteome database using Proteome Discoverer and FragPipe. The resulting peptide spectrum matches were converted into a spectral library using BiblioSpec.

Reanalysis of Data-dependent acquisition based proteomic datasets of Mycobacterium avium subsp. paratuberculosis, Mycobacterium marinum and Mycobacterium vaccae

Project description:Detection of species-specific proteotypic peptides for accurate and easy characterization of infectious non-tuberculous mycobacteria such as Mycobacterium avium subsp. paratuberculosis, Mycobacterium marinum and Mycobacterium vaccae is essential. Therefore, we carried out reanalysis of publicly available M. avium subsp. paratuberculosis, M. marinum and M. vaccae proteomic dataset PXD027444, PXD003766 and PASS00954 by proteome database search and followed by spectral library generation. The raw DDA data were searched against their respective reference proteome databases using Proteome Discoverer and FragPipe. The resulting peptide spectrum matches were converted into a spectral library using BiblioSpec.

Specificity of the innate immune responses to different classes of non-tuberculous mycobacteria

Project description:Mycobacterium avium is the most common nontuberculous mycobacterium (NTM) species causing infectious disease. Here, we characterized a M. avium infection model in zebrafish larvae, and compared it to M. marinum infection, a model of tuberculosis. Using RNAseq analysis, we found a distinct transcriptome response in cytokine-cytokine receptor interaction for M. avium and M. marinum infection. In addition, we found substantial differences in gene expression in metabolic pathways, phagosome formation, matrix remodeling, and apoptosis in response to these mycobacterial infections.

Global host transcriptional profiles following Mycobacterium avium subsp. paratuberculosis infection in mice

Project description:We focused on how Mycobacterium avium subsp. paratuberculosis influences the subsequent host response to investigate the host immunopathology accompanying the host anti-mycobacterial immune response during Mycobacterium avium subsp. paratuberculosis infection in spleen of mice. We analyzed altered transcription in the spleen of mice at 3, 6, and 12 weeks following Mycobacterium avium subsp. paratuberculosis infection.
