Project description:Data defines for the first time a whole bladder transcriptome of UPEC cystitis in female CBA mice using genome-wide expression profiling to map early host response pathways stemming from UPEC colonization We used microarrays to detail the global programme of gene expression in UPEC UTI in mice Whole mouse bladder collected at 2h following transurethral infection for RNA extraction and hybridization on Affymetrix microarrays. Non-pooled samples were used, with one array per mouse to expand power of expression profiles. Control mice received only PBS as a mock infection. Group sizes were five mice per group, and therefore five arrays were used per group.

Project description:Antimicrobial peptides (AMPs) serve key proposed roles in defending the urinary tract against invading uropathogens, but individual AMPs bearing greatest responsibility for these functions remain largely unknown. We identified RegIIIγ as the most transcriptionally upregulated AMP in bladder transcriptomes following uropathogenic Escherichia coli (UPEC) infection. We confirmed induction of RegIIIγ mRNA during cystitis and pyelonephritis by quantitative RT-PCR. Immunoblotting demonstrates increased bladder and urinary RegIIIγ protein levels following UPEC infection. Immunostaining localizes RegIIIγ protein to urothelial cells of infected bladders and kidneys. Human patients with cystitis and pyelonephritis exhibit increased urine levels of the orthologous HIP/PAP protein. Recombinant RegIIIγ protein does not demonstrate bactericidal activity toward UPEC in vitro, but does kill Staphylococcus saprophyticus in a dose-dependent manner. RegIIIγ knockout and control urinary tracts contain comparable bacterial burden following experimental inoculation of UPEC as well as Gram-positive uropathogens. Thus, while RegIIIγ and HIP/PAP expression occurs in human and murine UTI, their specific functions in the urinary tract remain uncertain.

Project description:Urinary tract infections (UTI) are common and recurrent. Both host genetics and UTI history impact susceptibility to recurrent UTI (rUTI) in women and in animal models. To identify shared patterns of host response that correlate with susceptibility, we investigated bladder inflammatory and transcriptional kinetics in acute and rUTI models. We found that TNFɑ signaling kinetics differed with mouse strain and infection history. Mice resistant to severe UTI/rUTI displayed a robust TNFɑ-dependent inflammation during the first 6 hours of acute cystitis, which waned by 24 hours; mice that are susceptible varied in their early responses but were prone to severe inflammation at 24 hours post-infection. Depletion of TNFɑ in an rUTI model revealed that early TNFɑ signaling promoted colonization resistance via exfoliation of infected bladder cells, but prolonged TNFɑ signaling exacerbated inflammation, thereby worsening infection. Host genetics and disease history impacts susceptibility by regulating the kinetics of a common TNFɑ pathway.

Project description:We compared the chnages in urinary bladder and iliac lymph nodes microRNAs in the control and experimental autoimmune cystitis in mice. A set of urinary bladder microRNAs (miRNAs) shows profound upregulation or downregulation in the expression profiles of the experimental IC as compared to control.

Project description:Uropathogenic Escherichia coli (UPEC) are the most common cause of urinary tract infection (UTI). UPEC normally reside in the intestine, and during establishment of UTI, it undergoes metabolic adaptations, first to urine and then upon tissue invasion to the bladder cell interior. In order to understand these adaptations, we used quantitative proteomic profiling to characterize protein expression of UPEC strain UTI89 growing in human urine and when inside J82 bladder cells. In order to facilitate detection of UPEC proteins over the excess amount of eukaryotic proteins in bladder cells, we developed a method where proteins from UTI89 grown in MOPS and urine was spiked-in to enhance detection of bacterial proteins. More than 2000 E. coli proteins were detected. During growth in urine, proteins associated with iron acquisition and several amino acid uptake and biosynthesis systems, in particular arginine metabolism, were significantly upregulated. During growth in J82 cells, proteins related to iron uptake and arginine metabolisms were upregulated together with proteins involved in sulphur compound turnover. Results suggested that UPEC experience a richer environment in bladder cells compared to urine. There was no direct correlation between upregulated proteins and proteins reported to be essential for infections, showing that upregulation during growth does not signify that the proteins are essential for growth under a condition.

Project description:To gain further information of the correlation and pathogenisis of UPEC and APEC, the in vivo expression of 152 specific genes in both murine urinary tract infection (UTI) model and chicken challenge model were compared to that of UPEC U17 and APEC E058 grown statically to exponential phase in rich medium, respectively.
