Key hub and bottleneck genes differentiate the macrophage response to virulent and attenuated Mycobacterium bovis

Project description:Mycobacterium bovis is an intracellular pathogen that causes tuberculosis in cattle. Following infection, the pathogen resides and persists inside host macrophages by subverting host immune responses via a diverse range of mechanisms. Here, a high-density bovine microarray platform was used to examine the bovine monocyte-derived macrophage transcriptome response to M. bovis infection relative to infection with the attenuated vaccine strain, M. bovis Bacille CalmetteM-bM-^@M-^SGuM-CM-)rin. Differentially expressed genes were identified (adjusted P-value M-bM-^IM-$ 0.01) and interaction networks generated across an infection time course of 2, 6 and 24 h. The largest number of biological interactions was observed in the 24 h network, which exhibited small-worldscale-free network properties. The 24 h network featured a small number of key hub and bottleneck gene nodes, including IKBKE, MYC, NFKB1 and EGR1 that differentiated the macrophage response to virulent and attenuated M. bovis strains, possibly via the modulation of host cell death mechanisms. These hub and bottleneck genes represent possible targets for immunomodulation of host macrophages by virulent mycobacterial species that enable their survival within a hostile environment. Affymetrix GeneChipM-BM-. Bovine Genome Arrays were used to examine gene expression from a paired comparison of bovine monocyte-derived macrophages (MDM) after in vitro challenge with Mycobacterium bovis versus M. bovis BCG across a time series of 2 hr, 6 hr and 24 hr post-challenge.

Transcriptional response of bovine moncocyte-derived macrophages to infection with strains of Mycobacterium bovis and Mycobacterium avium subspecies paratuberculosis

Project description:Mycobacterium bovis (M. bovis) and Mycobacterium avium subspecies paratuberculosis (MAP) are important pathogens of cattle, causing bovine tuberculosis and Johne’s disease respectively. M. bovis and MAP infect residential macrophages in the lung and intestines respectively and subvert the macrophage biology to create a survival niche. To investigate this interaction we simultaneously studied the transcriptional response of bovine monocyte-derived macrophages to infection with two strains of M. bovis (AF2122/97 and G18) and two strains of MAP (C & L1).

Following infection, the pathogen resides and persists inside host macrophages by subverting host immune responses via a diverse range of mechanisms. Here, a high-density bovine microarray platform was used to examine the bovine monocyte-derived macrophage transcriptome response to M. bovis infection relative to infection with the attenuated vaccine strain, M. bovis Bacille Calmette–Guérin. Differentially expressed genes were identified (adjusted P-value ≤ 0.01) and interaction networks generated across an infection time course of 2, 6 and 24 h. The largest number of biological interactions was observed in the 24 h network, which exhibited small-worldscale-free network properties.

Early response of bovine alveolar macrophages to infection with live and heat-killed Mycobacterium bovis

Project description:Bovine tuberculosis, caused by Mycobacterium bovis, is a disease of considerable economic importance yet comparatively little is known about the bovine immune response to the disease. Alveolar macrophages are one of the first cells to encounter mycobacteria following infection. In this experiment we investigated the early transcriptional response of bovine alveolar macrophages following infection with M. bovis. The transcriptional response to heat-killed M. bovis was also investigated to look for genes that are only differentially transcribed in response to the live organism.
