Effect of Mip inhibition on J774A.1 macrophage immune response during Burkholderia pseudomallei infection

Project description:Melioidosis, caused by the Gram-negative bacterium Burkholderia pseudomallei, is a disease endemic to South-East Asia and Northern Australia. Clinical presentation is highly variable, ranging from asymptomatic to fatal septicaemia, and thus the outcome of infection can depend on the host immune responses. The aim of this study was to characterise the macrophage immune response to B. pseudomallei in the presence of novel inhibitors targeting the virulence factor, Macrophage Infectivity Potentiator (Mip) protein. To do this. murine macrophage J774A.1 cells were infected with B. pseudomallei K96243 in the presence and absence of two small-molecule inhibitors designed to target the Mip protein. Global transcriptional profiling of macrophages infected with B. pseudomallei was analysed by RNA-Seq four hours post-infection. In the presence of Mip inhibitors, we found a significant reduction in the expression of pro-inflammatory cytokines highlighting the potential to utilize Mip inhibitors to dampen potentially harmful pro-inflammatory responses resulting from B. pseudomallei infection in macrophages. We then performed gene expression profiling analysis using data obtained from RNA-seq of J774A.1 macrophages infected with Burkholderia pseudomallei in the presence of two Mip inhibitors or vehicle control 4 hours post-infection

Burkholderia pseudomallei transcriptional adaptation in macrophage

Project description:This study reports the expression profile of intracellular B. pseudomallei following infection of human macrophage-like U937 cells. The transcriptome of intracellular B. pseudomallei harvested from macrophage cells over an infection period of 6 hr (1, 2, 4 and 6 hr post-infection) were compared to in vitro grown bacteria to identify genes whose expression is altered in response to intracellular growth. The experimental design of this study involved the total RNA from intracellular B. pseudomallei harvested from infected U937 cells at 4 selected time points with 3 biological replicates each. The microarray data from each time point was compared relative to in vitro grown bacteria in cell culture medium.

Role of ppiB in burkholderia pseudomallei

Project description:Burkholderia pseudomallei is the causative agent of melioidosis a disease endemic in South-East Asia and Northern Australia. The mortality rates in these areas are unacceptably high even with antibiotic treatment, attributed to intrinsic and acquired resistance of B. pseudomallei to antibiotics. With very few options for therapeutics there is an urgent requirement to identify anti-bacterial targets for the development of novel, effective treatments. In this study we examine the role and effect of ppiB on the proteome. Using LFQ analysis we show loss of ppiB has dramatic effect on the Burkholderia pseudomallei proteome.
