Abstract
BACKGROUND Obesity with its multiple comorbidities has become a global pandemia. We here report on the pathophysiological aspects of obesity-associated urinary bladder dysfunctions. MATERIAL AND METHODS Our results are based on multiple in vitro and in vivo studies including a high fat diet (HFD) rat animal model of which the details are given in the cited publications. RESULTS In cultured human detrusor muscle cells, obesity-related pathophysiological mechanisms were directly induced by the saturated free fatty acid palmitate. In HFD animals, we found serious fibrosis of the bladder wall and downregulation of the muscarinic M3-receptor leading to diminished contractility of the urinary bladder. Bariatric surgical intervention (sleeve gastrectomy) reversed the fibrosis. CONCLUSION Our results support the relevance of obesity for urological bladder dysfunction. The epidemic dimension of obesity with its steadily growing number of cases requires a re-evaluation of this pathological condition in the urological context.

Abstract
BACKGROUND Interleukin-6 (IL-6) is a pleiotropic cytokine which shows elevated plasma and urine levels in cancer and inflammatory diseases of the urinary tract. The aim of the study is to define IL-6 target gene regulation in cultivated human detrusor smooth muscle cells. PATIENTS AND METHODS The expression of IL-6 and IL-6R (gp80, gp130) was studied by confocal immunofluorescence, rtPCR and Western blotting. Lipopolysaccharide (LPS) stimulation experiments were conducted in smooth muscle cell cultures derived from bladder biopsies of four male tumor patients. RESULTS IL-6 and IL-6R expression was found in urothelium, lamina propria and detrusor cells. LPS stimulation evoked a time-dependent synthesis and/or release of IL-6, IL-6R and STAT3. CONCLUSIONS Our results favor the notion that IL-6 can stimulate various cells of the human urinary bladder. Both detrusor cells and urothelium can serve as a source of elevated IL-6 levels. Finding genes regulated by IL-6 could be of great value for new therapeutical approaches in cancer and chronic inflammation of the lower urinary tract.

Abstract
BACKGROUND Myofibroblasts play a pivotal role in numerous pathological alterations. Clarification of the structure and function and of the cellular plasticity of this cell type in the bladder may lead to new insights into the pathogenesis of lower urinary tract disorders. PATIENTS AND METHODS Bladder biopsies from patients with bladder carcinoma and interstitial cystitis were used to analyse the morphology and receptor expression using confocal immunofluorescence and electron microscopy. Cytokine effects and coupling behavior were tested in cultured myofibroblasts and detrusor smooth muscle cells. RESULTS Myofibroblasts are in close contact with the suburothelial capillary network. They express Cx43 and form functional syncytia. The expression of muscarinic and purinergic receptors is highly variable. Dye coupling experiments showed differences to detrusor myocytes. CONCLUSIONS Upregulation of smooth muscle cell alpha-actin and/or transdifferentiation into smooth muscle cells may contribute to the etiology of urge incontinence. A multi-step model is presented as a working hypothesis.

Abstract
BACKGROUND M3-specific inhibitors are currently preferred for anticholinergic therapy of OAB. However, not all of the patients profit from this regimen. This might reflect a heterogeneity of the patient group. The aim of this work is to define subgroups of patients with specific alterations of receptor expression and to profile the receptor expression individually. These receptor profiles might be used for the development of evidence-based "tailored" therapies. PATIENTS AND METHODS Detrusor probes from bladder carcinoma patients (BCa, n=9 F, n=7 male) and interstitial cystitis patients (IC, n=9 female) were examined using confocal immunofluorescence and PCR. RESULTS M2, M3, P2X1-3, and H1-3 mRNAs were demonstrated in detrusor tissue. As revealed by immunofluorescence, the M2 receptor expression was significantly higher in female compared to male BCa tissues. In addition, the M2 receptor was further upregulated in IC vs BCa in female detrusor. CONCLUSIONS IC patients showed specific alterations of their receptor profile. Individual receptor profiles might be used to optimize medicinal therapies.
