Project description:Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic and debilitating pain disorder of the bladder and urinary tract with poorly understood etiology. A definitive diagnosis of IC/BPS can be challenging because many symptoms of IC/BPS are shared with other urological disorders. An analysis of urine presents an attractive and non-invasive resource for monitoring and diagnosing IC/BPS. Here, a non-targeted LC-MS and LC-MS/MS-based peptidomics analysis of urine samples collected from IC/BPS patients were compared to urine samples from asymptomatic controls.

Project description:Interstitial cystitis (IC) and bladder pain syndrome are terms used to describe a heterogenous chronic pelvic and bladder pain disorder of unknown etiology. The goal of this pilot study was to determine if gene expression profiling of bladder biopsy tissue from patients experiencing symptoms could be used to separate the patients based on some clinical parameter. Gene expression profiles in bladder biopsy tissue from patients with: (1) low bladder capacity (defined here as <400 ml upon hydordistension), (2) normal capacity (M-bM-^IM-%400 ml), and (3) controls were compared. Gene expression profiles from low bladder capacity tissues differed significantly from normal capacity and control tissue, suggesting gene expression profiling may be a useful tool for better understanding IC disease pathophysiology.

Project description:The pathogenesis of interstitial cystitis/bladder pain syndrome (IC/BPS) remains incompletely understood. Bladder fibrosis is a significant histopathological feature of IC/BPS, particularly in non-Hunner-type IC (NHIC). Transient receptor potential cation channel subfamily C member 3 (TRPC3) is known to play a crucial role in myocardial and renal fibrosis. This study investigates the involvement of TRPC3 in bladder fibrosis associated with IC/BPS. A rat model of IC/BPS was established using cyclophosphamide (CYP, 50 mg/kg, intraperitoneally, every 3 days for 3 doses). Bulk RNA sequencing was used to identify differentially expressed transient receptor potential (TRP) channel genes in CYP-induced cystitis rats, whereas single-cell RNA sequencing was utilized to pinpoint the cell type predominantly expressing transient receptor potential cation channel subfamily C member 3 (TRPC3) . TRPC3 inhibition was achieved through intraperitoneal injection of Pyrazole 3 (Pyr3, 0.1 mg/kg or 1 mg/kg). Suprapubic mechanical allodynia was assessed using up-down method with von Frey filaments and micturition frequency was assessed by cystometry. The expression of TRPC3 and components of the transforming growth factor beta (TGF-β)/Smad signaling pathway (TGF-β, p-Smad2, and p-Smad3) in the bladder was analyzed by Western blot. Bladder fibrosis was assessed through Masson’s staining and detection of fibrosis markers (Vimentin, Collagen I, and Collagen III) using Western blot. The RNA and protein expression of TRPC3 was up-regulated in CYP-induced cystitis rats. TRPC3 inhibition led to significant improvements in suprapubic mechanical allodynia and reduced micturition frequency in CYP-induced cystitis rats. Western blot analyses revealed that markers of bladder fibrosis (Vimentin, Collagen I, and Collagen III) were markedly upregulated in CYP-induced cystitis rats. Masson’s staining showed an increased area of collagen fibers. Additionally, inhibition of TRPC3 resulted in significant downregulation of the TGF-β/Smad signaling pathway (TGF-β, p-Smad2, and p-Smad3) in CYP-induced cystitis rats. TRPC3 activation contributes to bladder fibrosis in IC/BPS. Inhibition of TRPC3 ameliorates suprapubic mechanical allodynia and micturition frequency in CYP-induced cystitis rats by downregulating the TGF-β/Smad pathway. TRPC3 represents a potential therapeutic target for managing bladder fibrosis in IC/BPS.

Project description:Recent evidence suggests that the descending modulatory pathways from the brainstem rostral ventromedial medulla (RVM) are important for bladder inflammatory pain. This study aimed to identify the long-term molecular changes in RVM neurons due to early life cystitis during neuronal development and the effect of reexposure later in adulthood. RVM tissues from two treatment protocols were used: (1) neonatal zymosan exposures with acute adult rechallenge (RC) and (2) only neonatal zymosan exposures (NRC). RNAseq analysis showed upregulation of several genes associated with synaptic plasticity (Grin1, Grip2, Notch1, Arc, and Scn2b) in the cystitis groups compared to controls in both protocols. The RC protocol exhibited a stronger treatment effect with significantly higher fold differences between the groups compared to the NRC protocol (p<0.001, fold differences RC vs NRC). In microarrays, miR-34a-5p showed cystitis-induced downregulation in both protocols. Bioinformatics analysis identified multiple 3’UTRs complementary binding sites for miR-34a-5p on Grin2b, Notch1, Grip2, Scn2b, and Arc genes. The enhanced response in the RC protocol indicates a possible priming effect of early life cystitis on rechallenge in adulthood. These long-term molecular alterations may play a critical role in the development of chronic bladder pain conditions as seen in patients with Interstitial Cystitis/Bladder pain syndrome

Project description:Hunner-type interstitial cystitis (HIC) is a rare, enigmatic inflammatory disease of the urinary bladder with no curative treatments. In this study, we aimed to characterize the unique cellular and immunological factors specifically involved in HIC by comparing with cystitis induced by Mycobacterium bovis bacillus Calmette–Guérin, which presents similar clinicopathological features to HIC. Here, we show that T helper 1/17 polarized immune responses accompanied by prominent overexpression of interferon (IFN)-γ, enhanced cGAS-STING cytosolic DNA sensing pathway, and increased plasma cell infiltration are the characteristic inflammatory features in HIC bladder. Further, we developed a novel mouse anti-IFN-γ DNA aptamer and observed that intravesical instillation of the aptamer significantly ameliorated bladder inflammation, pelvic pain and voiding dysfunction in a recently developed novel murine HIC mouse model with little migration into the blood. Our study provides the plausible basis for clinical translation of the anti-IFN-γ DNA aptamer in the treatment of human HIC.

Project description:Objectives: Much of the information to date in terms of subtypes and function of bladder urothelial cells were derived from anatomical location or by the expression of a small number of marker genes. To have a comprehensive map of the cellular anatomy of bladder urothelial cells, we performed single-cell RNA-sequencing to thoroughly characterize mouse bladder urothelium. Materials and methods: A total of 18,917 single cells from mouse bladder urothelium was analyzed by unbiased single-cell RNA sequencing. The expression of the novel cell marker was confirmed by immunofluorescence using urinary tract infections models. Results: Unsupervised clustering analysis identified 8 transcriptionally distinct cell subpopulations from mouse bladder urothelial cells. We discovered a novel type of bladder urothelial cells marked by Plxna4 that may be involved with host response and wound healing. We also found a group of basal-like cells labeled by ASPM that could be the progenitor cells of adult bladder urothelium. ASPM+ urothelial cells are significantly increased after injury by UPEC. In addition, specific transcription factors were found to be associated with urothelial cell differentiation. At the last, a number of interstitial cystitis/bladder pain syndrome-regulating genes were found differentially expressed among different urothelial cell subpopulations. Conclusions: Our study provides a comprehensive characterization of bladder urothelial cells, which is fundamental to understanding the biology of bladder urothelium and associated bladder disease.

Project description:Acute cystitis is rapidly becoming a therapeutic enigma, as antibiotic resistance is reducing the options to a minimum. Fortunately, new insights are now making it possible to explore immune response modifiers as alternatives to antibiotics. In patients with acute cystitis, infection triggers a rapid and potent inflammatory response in the bladder mucosa and clinical symptoms include pain, urgency and frequency of urination. The molecular basis of these symptoms is not well understood, but bacterial interactions with the bladder epithelium have been shown to create inflammatory cascades. This study examined how innate immune response genes influence the outcome of bladder infection and the pathogenesis of acute cystitis with a particular focus on IL-1β. C57BL/6 mice were intravesically infected with relevant uropathogenic Escherichia coli strain, CFT073. Acute cystitis in infected bladders was defined by macroscopic inspection of edema, hyperemia and purulent discharge followed by histology and immunohistochemistry, after 24 hours and seven days. Genetic determinants of transient bladder inflammation versus severe disease were subsequently identified using C57BL/6 mice with specific inflammasome gene deletions (Il1b-/-, Casp1-/-, Asc-/- and Nlrp3-/-). Using genome-wide transcriptomic analysis to characterize genes regulated by infection in the bladders of these mice, we identified acute cystitis as an IL-1β-driven, hyper-inflammatory disease. Consistent with such a role, Il1b-/- mice were protected from infection and pathology. In contrast Asc-/- and Nlrp3-/- mice developed progressive IL-1β-driven bladder inflammation and severe pathology, caused by a new, non-canonical IL-1β processing mechanism, involving the metalloproteinase MMP-7. Using IL-1β and MMP-7 as targets for immunotherapy, we succeeded in protecting susceptible Asc-/- mice against acute cystitis, confirming the potential of immunotherapy for this indication. The results reproduce important aspects of human cystitis in the murine urinary tract infection (UTI) model and provide a comprehensive molecular framework for the pathogenesis and immunotherapy of acute cystitis, one of the most common bacterial infections in man.
