Abstract
The extent of immune-mediated hepatic damage (such as in viral hepatitis) is characterised by the downregulation of cytochrome P450s (CYPs), a class of drug-metabolising enzymes. However, whether this downregulation aids liver cells in maintaining their homeostasis or whether the damage is aggravated remains largely unexplored. Herein, we evaluated the effects of phosphorylation mediated by the protein kinase C (PKC)/cAMP-response element binding protein (CREB) and nitration mediated by inducible nitric oxide synthase (iNOS) on the downregulation of CYP2E1 during immune-mediated liver injury. Additionally, we investigated the regulatory mechanism mediated by the nuclear factor κB (NF-κB). The rat model of immune-mediated liver injury was replicated by administering a single i.v. injection of Bacillus Calmette-Guerin (BCG, 125 mg/kg) vaccine and three i.p. injections of ammonium pyrrolidine dithiocarbamate (25, 50, 100 mg/kg/d, days 11, 12, and 13); blood was then collected on day 14. Subsequently, the livers were extracted to identify the different pharmacokinetic and biochemical indicators involved in the process. Our study reports new findings on the dependence between PKC-mediated CREB phosphorylation in the anti-inflammatory pathway and nitration emergency induced by iNOS in pro-inflammatory pathways in the NF-κB pathway. The interaction of these two pathways leads to the downregulation and recovery of CYP2E1, thus alleviating inflammation and nitration stress. Our results confirm that BCG-mediated downregulation of CYP2E1 is linked to iNOS-induced nitration and PKC/NF-κB-mediated CREB phosphorylation, and that NF-κB is an important molecular target in this process. These findings suggest that the downregulation of CYP2E1 may be an autonomous process characteristic of liver cells, helping them adapt to environmental changes, alleviate further hypoxia in inflamed tissues, and minimise exposure to toxic and harmful metabolites.

Abstract
Tuberculosis (TB) is the leading cause of human death worldwide due to Mycobacterium tuberculosis (Mtb) infection. Mtb infection can cause macrophage pyroptosis. PERK, as a signaling pathway protein on the endoplasmic reticulum, plays an important role in infectious diseases. It is not clear whether PERK is involved in the regulation of pyroptosis of macrophages during Mtb infection. In this study, Bacillus Calmette-Guerin (BCG) infection resulted in high expression of pro-caspase-1, caspase-1 p20, GSDMD-N, and p-PERK in the THP-1 macrophage, being downregulated with the pre-treatment of GSK2656157, a PERK inhibitor. In addition, GSK2656157 inhibited the secretion of IL-1β and IL-18, cell content release, and cell membrane rupture, as well as the decline in cell viability induced by BCG infection. Similarly, GSK2656157 treatment downregulated the expressions of pro-caspase-1, caspase-1 p20, caspase-11, IL-1β p17, IL-18 p22, GSDMD, GSDMD-N, and p-PERK, as well as reducing fibrous tissue hyperplasia, inflammatory infiltration, and the bacterial load in the lung tissue of C57BL/6J mice infected with BCG. In conclusion, the inhibition of PERK alleviated pyroptosis induced by BCG infection, which has an effect of resisting infection.

Abstract
Upper tract urothelial carcinoma (UTUC) poses unique challenges in diagnosis and treatment. This comprehensive review focuses on prophylactic intravesical therapy for UTUC, summarizing key aspects of intravesical therapy in various clinical scenarios, including concurrent with or following radical nephroureterectomy, kidney-sparing surgery, ureteroscopy-guided biopsy. The incidence of intravesical recurrence in UTUC after surgical treatment is significant, necessitating effective preventive measures. Intravesical therapy plays a vital role in reducing the risk of bladder recurrence following UTUC surgery. Tailoring timing, drug selection, dosage, and frequency is vital in optimizing treatment outcomes and reducing intravesical recurrence risk in UTUC. This review provides a comprehensive summary of the history, clinical trials, guideline recommendations, and clinical applications of intravesical therapy for UTUC. It also discusses the future directions based on current clinical needs and ongoing trials. Future directions entail optimizing dosage, treatment duration, and drug selection, as well as exploring novel agents and combination therapies. Intravesical therapy holds tremendous potential in improving outcomes for UTUC patients and reducing the risk of bladder recurrence. Although advancements have been made in UTUC treatment research, further refinements are necessary to enhance efficacy and safety.

Abstract
Background The epidemiology of infants who exhibited the Koch-like phenomenon after Bacillus Calmette-Guérin vaccination and who subsequently tested positive in interferon-γ release assay (IGRA) was compared to that of those who tested negative. The reports of pediatricians on the phenomenon to the health authorities of Japan were retrieved and analyzed. Methods In 2013-2019, 790 infants with such events were reported with IGRA test results available, of whom 81 (10.3%) tested positive and 709 (89.7%) negative. Results The infants who were IGRA positive did not show an increasing trend (P = 0.06, P = 0.60), whereas those who were IGRA negative showed a significantly increasing trend (P = 0.42, P = 0.0002). The infants who were IGRA positive did not exhibit seasonality, whereas those who were IGRA negative had a higher number of cases in winter than in summer. The rates of infants who were IGRA positive per 10 million live births showed a significant correlation with the tuberculosis (TB) notification rates by prefecture (P = 0.41, P = 0.004), whereas those who were IGRA negative did not (P = 0.04, P = 0.78). Conclusion The IGRA-positive infants were distributed quite differently from those who were IGRA negative and appeared more likely to be infected with TB. Reports of pediatricians on the Koch-like phenomenon should continuously be collected as the reports reflect a risk of TB infection including TB outbreaks among infants in Japan. The reports should include IGRA test results as IGRA is more specific than tuberculin skin testing. Infants with IGRA-positive results should be followed up for 2-3 years to determine their final outcomes.

Abstract
Background: A marker of urothelial damage could be helpful for early detection and monitoring of local toxicity due to intravesical therapy for non-muscle invasive bladder cancer (NMIBC). The aim of the study was to investigate the correlation between fibronectin (FN) gene expression in bladder washings and local toxicity secondary to adjuvant intravesical therapy. Materials and methods: Patients undergoing adjuvant intravesical therapy for NMIBC and age-matched healthy patients were enrolled. Real time polymerase chain reaction was performed to analyze FN expression in bladder washings. Local toxicity was classified as: 0–1 mild (no medical therapy), 2 moderate (medical therapy and/or instillation postponed), 3 severe (discontinuation of therapy). Results: Seventy-two patients and 21 controls entered the study. A useful pellet was obtained in 58 patients and 18 controls. Intravesical Bacillus Calmette–Guerin (BCG), Epirubicin and Mitomycin C was offered to 69%, 13.8% and 17.2% of patients respectively. Compared with healthy controls (FN = 1.0 fold), overall median FN expression before adjuvant intravesical therapy was 1.73 fold [interquartile range (IQR) 0.8–2.3], while during therapy median FN expression increased to 3.41 (IQR: 1.6–6.1) fold. Considering 40 intermediate and high-risk patients undergoing intravesical BCG, median FN expression before adjuvant treatment was 1.92 [(IQR: 1.0–2.7) fold, increasing up to 4.1 (IQR: 1.9–6.6) during therapy. In more detail, FN increased during BCG therapy, showing a median expression of 4.22 (IQR: 2.2–5.5) and 6.16 (IQR: 2.6–8.7) fold in presence of grade 2 and 3 toxicity respectively, while remaining more or less stable in asymptomatic patients. After receiver operating characteristic curve analysis, FN value of 3.6 fold resulted, corresponding to 75% sensitivity and 69% specificity to predict grade 2–3 toxicity events (area under the curve 0.74, 95% confidence interval 0.63–0.85, p = 0.001). Conclusion: Our study validated the correlation between FN expression and urothelial damage. BCG seems to induce a urothelial activation with FN overexpression during adjuvant intravesical therapy. Grade of toxicity was related to FN expression.

Abstract
Tumor infiltrating lymphocytes (TIL) therapy was shown to provide durable objective response in patients with metastatic melanoma. As a fundamental first step to bring TIL therapy to clinical use, identification of patients whose tumors yield optimal numbers of reactive TIL is indispensable. We have previously shown that expansion of tumor reactive TIL from primary bladder tumors and lymph node metastases is feasible. Here, we performed TIL harvesting from additional surgical specimens (additional 31 primary tumors and 10 lymph nodes) to generate a heterogenous cohort of 53 patients with bladder cancer (BC) to evaluate the tumor characteristics that lead to tumor-reactive TIL expansion. Among a total of 53 patients, overall TIL growth from tumor samples were 37/53 (69.8%) and overall anti-tumor reactive TIL were 26/35 (74.3%). Mixed urothelial carcinoma is associated with higher anti-tumor reactivity of expanded TIL than pure urothelial carcinoma (89.5% vs. 56.3%, p=0.049). The anti-tumor reactivity of expanded TIL from primary tumors previously treated with BCG immunotherapy were lower (33.3% vs. 82.6%, p=0.027) although T-cell phenotype (CD3+, CD4+, CD8+, and CD56+) was similar regardless prior of BCG therapy. Addition of agonistic 4-1BB antibody in culture media with IL-2 improved the number of expanded TIL from primary tumors previously treated with BCG immunotherapy. There was no significant difference between basal and luminal subtype tumors in terms of viable and reactive TIL growth. Our study demonstrates that TIL expansion is feasible across all BC patients and BC subtypes, and we suggest that TIL therapy can be a reasonable treatment strategy for various manifestations of BC.

Abstract
Purpose: The objective of this study was to investigate the bactericidal effects of high intensity focused ultrasound (HIFU) on Bacillus Calmette-Guerin (BCG, a substitute for Mycobacterium tuberculosis) in vitro and in vivo, and to explore the underlying mechanisms. Materials and methods: HIFU, at a fixed frequency of 1 MHz, was applied to both BCG culture suspensions and subcutaneous BCG abscesses in rats. Results: HIFU irradiation significantly reduced the bacterial survival rate and caused temperature elevations both in vitro and in vivo. Furthermore, BCG suspensions irradiated for 15 s at 3185 and 6369 W/cm2 had increased cell wall damage, which resulted in morphological changes compared to the untreated control group. Additionally, we observed histological changes in the rat subcutaneous abscesses after HIFU ablation at 6369 W/cm2. H&E staining of infected lesions showed coagulative necrosis with central nucleus dissolution and increased infiltration of inflammatory cells, as well as nuclear pyknosis and nuclear fragmentation in the periphery. The volumes of the subcutaneous abscesses in the HIFU-treated group were significantly lower than those in the sham-treated group. Conclusion: HIFU has the therapeutic potential to treat BCG-infected tissues in rats. We theorize that a combination of mechanical, cavitation, and thermal effects most efficiently inactivate BCG bacteria via HIFU. This study is expected to provide a bio-plausible basis for a noninvasive and effective treatment for tuberculosis.

Abstract
Introduction The aim of this study was to explore the effectiveness of BCG vaccination on the severity of clinical symptoms of pulmonary tuberculosis symptoms (PTb) in patients from the northwest and west of Iran. Materials and methods In a cross sectional study of 358 patients with a diagnosis of PTb, 11 clinical symptoms, including cough, chest pain, dyspnea, sputum, fever, hemoptysis, weight loss, loss of appetite, wheezing, weakness, and fatigue were checked and patients with a score of six or more were placed in the severe clinical symptoms group. BCG vaccination scar and clinical symptoms were examined and recorded. Results Of the subjects included in this study, 264 cases (73.7%) had no BCG vaccination scar. Comparison of the severity of clinical symptoms of PTb in patients with BCG vaccine history to those lacking vaccination history revealed lower symptom severity in patients who had been vaccinated (vaccine effectiveness = 95.5%; p < 0.00001) Conclusion The results of this study may imply that Adjusting for age sex and smoking status, BCG vaccination decreases the severity of clinical symptoms in patients with PTb. We suggest performing a retrospective cohort study on a larger population.

Abstract
PURPOSE To provide a summary of the Third International Consultation on Bladder Cancer recommendations for the management of non-muscle invasive bladder cancer (NMIBC). METHODS A detailed review of the literature was performed focusing on original articles for the management of NMIBC. An international committee assessed and graded the articles based on the Oxford Centre for Evidence-based Medicine system. The entire spectrum of NMIBC was covered such as prognostic factors of recurrence and progression, risk stratification, staging, management of positive urine cytology with negative white light cystoscopy, indications of bladder and prostatic urethral biopsies, management of Ta low grade (LG) and high risk tumors (Ta high grade [HG], T1, carcinoma in situ [CIS]), impact of BCG strain and host on outcomes, management of complications of intravesical therapy, role of alternative therapies, indications for early cystectomy, surveillance strategies, and new treatments. The working group provides several recommendations on the management of NMIBC. RESULTS Recommendations were summarized with regard to staging; management of primary and recurrent LG Ta and high risk disease, positive urine cytology with negative white light cystoscopy and prostatic urethral involvement; indications for timely cystectomy; and surveillance strategies. CONCLUSION NMIBC remains a common and challenging malignancy to manage. Accurate staging, grading, and risk stratification are critical determinants of the management and outcomes of these patients. Current tools for risk stratification are limited but informative, and should be used in clinical practice when determining diagnosis, surveillance, and treatment of NMIBC.

Abstract
Intravesical Bacillus Calmette–Guerin (BCG) immunotherapy is a proven, effective treatment for intermediate- and high-risk non-muscle-invasive bladder cancer. Minor side effects are common and expected but systemic effects can occur in <5% of treated patients. We present a rare case of a 49-year-old male that presented with fever and chills after 3 weeks of intravesical BCG therapy post transurethral resection of bladder tumor. New renal lesions were present on contrast-enhanced computed tomography scan which was histologically proven to be necrotizing renal granulomatosis.

Abstract
BACKGROUND Although the BCG vaccine remains the only available vaccine, a number of complications from local to systemic adverse reactions can occur. OBJECTIVE The aim of the study was to review the clinical features and treatment of Bacillus Calmette-Guérin (BCG) complications in children. METHODS Children with clinical and laboratory findings compatible with a diagnosis of local complication and disseminated disease at Masih Daneshvari Medical Center were enrolled from March 2013 to September 2015. RESULTS Among 49 children with BCG complications, 35 (71%) had local complications and 14 (29%) had disseminated disease. The mean age at presentation was nine months (range: 1m-13y). The male to female ratio was 1.7:1. Suppurative lymphadenitis was seen in 25 of 35 (71%) cases. Among cases with disseminated disease, primary immunodeficiency (PID) was identified in nine (64%) cases. All cases with non-suppurative lymphadenitis were managed conservatively. Twenty (80%) cases with suppurative lymphadenitis were managed differently with medical treatment or surgery. In disseminated cases, three (43%) were treated with only medical treatment and eight (57%) with both medical and surgical treatment. CONCLUSIONS Most children with BCG complications had a local disease in our study. A higher rate of disseminated disease was also observed. In addition, PID was identified in most children with disseminated disease. Development of more appropriate BCG vaccines and changing the current vaccination programme in cases with suspected PID are required in our country.

Abstract
The irradiated, allogeneic, cellular CSF-470 vaccine plus Bacillus Calmette–Guerin (BCG) and recombinant human granulocyte macrophage-colony stimulating factor (rhGM-CSF) is being tested against medium-dose IFN-α2b in stages IIB–III cutaneous melanoma (CM) patients (pts) after surgery in an open, randomized, Phase II/III study. We present the results of the Phase II part of the ongoing CASVAC-0401 study (ClinicalTrials.gov: NCT01729663). Thirty-one pts were randomized to the CSF-470 vaccine (n = 20) or to the IFN-α2b arm (n = 11). During the 2-year treatment, immunized pts should receive 13 vaccinations. On day 1 of each visit, 1.6 × 107 irradiated CSF-470 cells plus 106 colony-forming units BCG plus 100 µg rhGM-CSF were administered intradermally, followed on days 2–4 by 100 µg rhGM-CSF. IFN-α2b pts should receive 10 million units (MU)/day/5 days a week for 4 weeks; then 5 MU thrice weekly for 23 months. Toxicity and quality of life (QOL) were evaluated at each visit. With a mean and a maximum follow-up of 39.4 and 83 months, respectively, a significant benefit in the distant metastasis-free survival (DMFS) for CSF-470 was observed (p = 0.022). Immune monitoring showed an increase in antitumoral cellular and humoral response in vaccinated pts. CSF-470 was well tolerated; 20/20 pts presented grades 1–2 dermic reactions at the vaccination site; 3/20 pts presented grade 3 allergic reactions. Other adverse events (AEs) were grade 1. Pts in the IFN-α2b arm presented grades 2–3 hematological (7/11), hepatic (2/11), and cardiac (1/11) toxicity; AEs in 9/11 pts forced treatment interruptions. QOL was significantly superior in the vaccine arm (p < 0.0001). Our results suggest that CSF-470 vaccine plus BCG plus GM-CSF can significantly prolong, with lower toxicity, the DMFS of high-risk CM pts with respect to medium-dose IFN-α2b. The continuation of a Phase III part of the CASVAC-0401 study is encouraged.

Abstract
BACKGROUND The new modalities for treating patients with non-muscle invasive bladder cancer (NMIBC) for whom BCG (Bacillus Calmette-Guerin) has failed or is contraindicated are recently increasing due to the development of new drugs. Although agents like mitomycin C and BCG are routinely used, there is a need for more potent and/or less-toxic agents. In this scenario, a new perspective is represented by P-MAPA (Protein Aggregate Magnesium-Ammonium Phospholinoleate-Palmitoleate Anhydride), developed by Farmabrasilis (non-profit research network). This study detailed and characterized the mechanisms of action of P-MAPA based on activation of mediators of Toll-like Receptors (TLRs) 2 and 4 signaling pathways and p53 in regulating angiogenesis and apoptosis in an animal model of NMIBC, as well as, compared these mechanisms with BCG treatment. RESULTS Our results demonstrated the activation of the immune system by BCG (MyD88-dependent pathway) resulted in increased inflammatory cytokines. However, P-MAPA intravesical immunotherapy led to distinct activation of TLRs 2 and 4-mediated innate immune system, resulting in increased interferons signaling pathway (TRIF-dependent pathway), which was more effective in the NMIBC treatment. Interferon signaling pathway activation induced by P-MAPA led to increase of iNOS protein levels, resulting in apoptosis and histopathological recovery. Additionally, P-MAPA immunotherapy increased wild-type p53 protein levels. The increased wild-type p53 protein levels were fundamental to NO-induced apoptosis and the up-regulation of BAX. Furthermore, interferon signaling pathway induction and increased p53 protein levels by P-MAPA led to important antitumor effects, not only suppressing abnormal cell proliferation, but also by preventing continuous expansion of tumor mass through suppression of angiogenesis, which was characterized by decreased VEGF and increased endostatin protein levels. CONCLUSIONS Thus, P-MAPA immunotherapy could be considered an important therapeutic strategy for NMIBC, as well as, opens a new perspective for treatment of patients that are refractory or resistant to BCG intravesical therapy.

Abstract
BACKGROUND Intravesical Bacillus Calmette-Guerin (BCG) has been the standard of care for the prevention of nonmuscle invasive bladder cancer (NMIBC) recurrence following resection. Attempts to improve on the result by combining it with other agents have largely failed. This study addresses the result of BCG therapy in our patient population and compares the result with our combination BCG and interferon therapy published earlier. MATERIALS AND METHODS The medical records of patients diagnosed with NMIBC and treated with transurethral resection and intravesical BCG were reviewed. Univariate analysis was performed on most known prognostic factors. Results were compared to published data on the use of BCG and interferon from the same institution. RESULTS Thirty-one patients were identified. Median age was 66 (range 33-109), 80.6% were males. Fourteen patients (45%) had ≤ 3 tumors and 18 (58.1%) had T1 lesions. Four patients (12.9%) had Grade 3 tumors and 25 (80.6%) had Grade 2 tumors. One patient (3.2) had concurrent carcinoma in situ and 11 (35.5%) were treated upon initial diagnosis. At 5 years, the relapse-free survival was 61.3% (95% confidence interval (CI) 44.2-78.4%), progression-free survival was 85.6% (95% CI 73.3-97.9%), and overall survival was 93% (95% CI 84.1-100%). Comparison with the BCG and interferon data showed no significant difference. CONCLUSION The result of BCG therapy in our patient population is similar to western reported data. Efficacy of BCG alone is equal to BCG and interferon within our institution.

Abstract
Without a doubt, the synchronization of public health intervention on health issues along the international border will enhance the control of epidemic-prone disease and other health-related behavior. However, the lack of holistic planning and the involvement of the members of border communities could result in undesired health related events. This report advanced reasons that could have resulted in a child receiving two separate doses of Bacillus Calmette–Guerin vaccine within the first 4 days of life in two different health facilities. Finally, this report highlighted the need for proactive community participation and the need for consensus by experts on guidelines on how to deal with such cases particularly in the unfortunate event of adverse reactions.

Abstract
Intravesical Bacillus Calmette-Guerin (BCG) vaccine is the preferred first line treatment for non-muscle invasive bladder carcinoma (NMIBC) in order to prevent recurrence and progression of cancer. There is ongoing need for the rational selection of i) BCG dose, ii) frequency of BCG administration along with iii) synergistic adjuvant therapy and iv) a reliable set of biochemical markers relevant to tumor response. In this review we evaluate cellular and molecular markers pertinent to the immunological response triggered by the BCG instillation and respective mathematical models of the treatment. Specific examples of markers include diverse immune cells, genetic polymorphisms, miRNAs, epigenetics, immunohistochemistry and molecular biology 'beacons' as exemplified by cell surface proteins, cytokines, signaling proteins and enzymes. We identified tumor associated macrophages (TAMs), human leukocyte antigen (HLA) class I, a combination of Ki-67/CK20, IL-2, IL-8 and IL-6/IL-10 ratio as the most promising markers for both pre-BCG and post-BCG treatment suitable for the simulation studies. The intricate and patient-specific nature of these data warrants the use of powerful multi-parametral mathematical methods in combination with molecular/cellular biology insight and clinical input.

Abstract
It is nearly 40 years since Bacillus Calmette-Guérin (BCG) was first used as an immunotherapy to treat superficial bladder cancer. Despite its limitations, to date it has not been surpassed by any other treatment. As a better understanding of its mechanism of action and the clinical response to it have evolved, some of the questions around optimal dosing and treatment protocols have been answered. However, its potential for toxicity and failure to produce the desired clinical effect in a significant cohort of patients presents an ongoing challenge to clinicians and researchers alike. This review summarizes the evidence behind the established mechanism of action of BCG in bladder cancer, highlighting the extensive array of immune molecules that have been implicated in its action. The clinical aspects of BCG are discussed, including its role in reducing recurrence and progression, the optimal treatment regime, toxicity and, in light of new evidence, whether or not there is a superior BCG strain. The problems of toxicity and non-responders to BCG have led to development of new techniques aimed at addressing these pitfalls. The progress made in the laboratory has led to the identification of novel targets for the development of new immunotherapies. This includes the potential augmentation of BCG with various immune factors through to techniques avoiding the use of BCG altogether; for example, using interferon-activated mononuclear cells, BCG cell wall, or BCG cell wall skeleton. The potential role of gene, virus, or photodynamic therapy as an alternative to BCG is also reviewed. Recent interest in the immune check point system has led to the development of monoclonal antibodies against proteins involved in this pathway. Early findings suggest benefit in metastatic disease, although the role in superficial bladder cancer remains unclear.

Abstract
The aim of the study is to evaluate mRNA/protein expression of zinc finger protein 165 (ZNF165) in transitional cell carcinomas (TCCs) of urinary bladder and correlate its expression with the clinicopathological characteristics of patients. In this study, the methods of quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) were utilized to evaluate mRNA/protein expression of ZNF165 in TCC. Independent Student's t test, ANOVA and Chi-square (χ(2)) were used to analyze the data statistically. We observed overexpression of ZNF165 mRNA in testis and majority (59.2%) of TCC patients. ZNF165 mRNA expression was also detected in adjacent noncancerous tissues (ANCTs) and some other normal tissues. Relative mean fold expression of ZNF165 mRNA was found to be significantly (p<0.01) higher in muscle-invasive bladder cancer (MIBC) as compared to non-muscle-invasive bladder cancer (NMIBC) patients. (12.11±9.57 vs. 5.72±2.61, p=0.009). ZNF165 protein expression was demonstrated on archival formalin-fixed, paraffin-embedded (FFPE) bladder tissues using IHC and nuclear staining pattern was detected. No significant difference was observed in protein expression of ZNF165 between the two groups (NMIBC and MIBC patients) (61.1% vs. 55.2%, p=0.629). No significant protein expression of ZNF165 was observed among ANCTs and benign prostatic hyperplasia (BPH) used as control. Our study results suggest that ZNF165 mRNA/protein expression was observed in TCC of human urinary bladder and might be used as a novel diagnostic biomarker and as well a vaccine target in development of urinary bladder cancer specific immunotherapy.

Abstract
Prostaglandins (PGs) and nitric oxide (NO) may be involved in the pathophysiology of depression. Since NSAIDs decrease PGs and NO production, they may have an antidepressant effect. The aim of the present work was to explore a possible antidepressant action of ibuprofen in the new model of Bacillus Calmette-Guerin (BCG) induced depression. Mice injected with BCG (10(7) CFU/mouse intraperitoneally) showed an increase in the total immobility time during the forced swim test (FST) and the tail suspension test (TST) and an increase in cerebral PGE2 and NO levels. Fluoxetine administered in drinking water at a dose of 80 mg/l, 5 days before BCG and for 2 more weeks resulted in significant decrease in total immobility time during FST and TST and in cerebral PGE2 and NO levels. Both ibuprofen (200 mg/l) and L-NAME (1 g/l) administered in drinking water 24 h before BCG and for 2 more weeks resulted in decrease in the total immobility time during FST and TST and in cerebral PGE2 and NO levels, which was comparable to fluoxetine's effect. On the other hand, l-arginine administered at a dose of 6 g/l in drinking water together with ibuprofen or fluoxetine reversed their effect on FST, TST and cerebral PGE2 and NO levels. Immunohistochemistry showed a decrease in COX-1 and i-NOS immunoreactivity in the CA1 and CA3 areas of the hippocampus following ibuprofen treatment. These results suggest that ibuprofen may have an antidepressant effect through inhibition of PGE2 and NO production, especially in depression secondary to chronic inflammation.
