: Different diseases lead, during their advanced stages, to chronic or acute liver failure, whose unique treatment consists in organ transplantation. The success of intervention is limited by host immune response and graft rejection. Immunosuppressant drugs permitted improving organ transplantation but they cannot completely solve the problem and their management is delicate, especially during the early stages of treatment. Thus, new tools to set an efficient modulation of immune response are required...

Internal radiation strategies hold great promise for glioblastoma (GB) therapy. We previously developed a nanovectorized radiotherapy that consists of lipid nanocapsules loaded with a lipophilic complex of Rhenium-188 (LNC(188)Re-SSS). This approach resulted in an 83 % cure rate in the 9L rat glioma model, showing great promise. The efficacy of LNC(188)Re-SSS treatment was optimized through the induction of a T-cell immune response in this model, as it is highly immunogenic. However, this is not representative of the human situation where T-cell suppression is usually encountered in GB patients...

PURPOSE: Urethral strictures are a common disease of the lower urinary tract in men. At present, the use of buccal mucosa is the method of choice for long or recurrent strictures. However, autologous tissue-engineered grafts are still under investigation for reconstructive urological surgery. The aim of this pilot study was to evaluate the use of human urothelial cells (HUC) seeded on bovine collagen type I-based cell carriers (CCC) in an animal model and to evaluate short-term outcome of the surgical procedure...

BACKGROUND: In recent years, immunomodulatory mechanisms of mesenchymal stem/stromal cells (MSCs) from bone marrow and other "classic" sources have been described. However, the phenotypic and functional properties of tumor MSCs are poorly understood. The aim of this study was to analyze the immunosuppressive capacity of cervical cancer-derived MSCs (CeCa-MSCs) on effector T lymphocytes through the purinergic pathway. METHODS: We determined the expression and functional activity of the membrane-associated ectonucleotidases CD39 and CD73 on CeCa-MSCs and normal cervical tissue-derived MSCs (NCx-MSCs)...

HIV disease has dramatically changed in the last two decades from a progressive, lethal disease to a chronic manageable condition. These changes are due to the availability of potent antiretroviral combination therapy, which also have the potential to contribute significantly to the control of the epidemic. Among persons living with HIV, incidence of immunosuppression-related opportunistic illnesses has clearly decreased, while an increase was observed in the prevalence of age-related noncommunicable comorbidities, including cardiovascular, metabolic, renal, bone and hepatic disease, due to chronic inflammatory state and to an overall aging of the population of persons with HIV...

Mesenchymal stem cells (MSCs) are generally used in regenerative medicine, tissue engineering and therapy for immune disorder diseases. However, due to the immunosuppressive function of MSCs, the application of MSCs in breast cancer therapy remains limited. Sirt1 is the closest mammalian homologue of the yeast enzyme Sir2 which has an established capacity to influence yeast replicative lifespan. In this study, we demonstrated the effect of MSCs with Sirt1 overexpression (MSCs-Sirt1) in mice bearing 4T1 breast cancer and investigated the underlying mechanism...

Non-melanoma skin cancer (NMSC) is the most common malignancy among the Caucasian population. Photodynamic therapy (PDT) is gaining popularity for the treatment of basal cell carcinoma (BCC), Bowen's disease (BD) and actinic keratosis (AK). A topical or systemic exogenous photosensitiser, results in selective uptake by malignant cells. Protoporphyrin IX (PpIX) is produced then activated by the introduction of a light source. Daylight-mediated MAL (methyl aminolaevulinate) PDT for AKs has the advantage of decreased pain and better patient tolerance...

Developments of genome amplification techniques have rapidly expanded the family of human polyomaviruses (PyV). Following infection early in life, PyV persist in their hosts and are generally of no clinical consequence. High-level replication of PyV can occur in patients under immunosuppressive or immunomodulatory therapy and causes severe clinical entities, such as progressive multifocal leukoencephalopathy, polyomavirus-associated nephropathy or Merkel cell carcinoma. The characterization of known and newly-discovered human PyV, their relationship to human health, and the mechanisms underlying pathogenesis remain to be elucidated...

Surgical management of contaminated hand wounds may seem anecdotal, but such injuries actually account for an appreciable amount of the activity in emergency hand centers, and recommendations put forward by scientific societies differ. Dealing effectively with this public health issue calls for clarifying the usefulness of the various available treatments. Our study's objective was to determine the effectiveness of surgical debridement. In this prospective study, 92 patients with contaminated hand wounds underwent surgical debridement...

An analysis of the impact of orphanhood at antiretroviral therapy (ART) initiation on HIV outcomes in Asia included 4300 children; 51% were male. At ART initiation, 1805 (42%) were non-orphans (median age: 3 years), 1437 (33%) were single orphans (6 years) and 1058 (25%) were double orphans (7 years). Ten-year post-ART survival was 93.4-95.2% across orphan categories. Clinic transfers were higher among single and double orphans than non-orphans (41% vs 11%, P<0.001). On multivariate analysis, children ≥3 years at ART initiation (hazard ratio 1...

We previously reported that the CopA3 peptide (LLCIALRKK, D-form) originally isolated from the Korean dung beetle has antimicrobial and immunosuppressive effects. However, the high cost of producing the synthetic peptide, especially the D-form, has limited the development of CopA3 for therapeutic purposes. Here, we investigated whether the CopA3 deletion derivative, CopA5, which is composed of only five amino acids (LLCIA) and has the L-form structure, could inhibit the lipopolysaccharide (LPS)-induced activation of macrophages...

Programmed death-ligand 1 (PD-L1) expression in tumor tissue is under investigation as a candidate biomarker in immuno-oncology dug development. The soluble form of PD-L1 (sPDL1) is suggested to have immunosuppressive activity. In this study, we measured the serum level of sPDL1 and evaluated its prognostic implication in biliary tract cancer (BTC). Blood was collected from 158 advanced BTC patients (68 intrahepatic cholangiocarcinoma, 56 gallbladder cancer, 22 extrahepatic cholangiocarcinoma and 12 ampulla of vater cancer) before initiation of palliative chemotherapy...

Targeting immune cells or factors are effective for patients with solid tumors. Myeloid-derived suppressor cells (MDSCs) are known to have immunosuppressive functions, and the levels of MDSCs in patients with solid tumor are assumed to have prognostic values. This meta-analysis aimed at evaluating the relationship between MDSCs and the prognosis of patients with solid tumors. We searched articles in PUBMED and EMBASE comprehensively, updated to March 2016. Eight studies with 442 patients were included in the meta-analysis...

Porcine reproductive and respiratory syndrome virus (PRRSV) infection was diagnosed in 6 Göttingen minipigs (Sus scrofa domestica) with severe interstitial pneumonia. The virus was defined as a North American (NA) subtype virus, which is common in the commercial pig population and might be derived from a widely used attenuated live-virus vaccine in Europe. The ORF5 sequence of the isolated PRRSV was 98% identical to the vaccine virus. The affected pigs were part of a lung transplantation model and received tacrolimus and steroids as well as irradiation or CD8 antibody for immunosuppression...

Recurrence of hepatitis C virus (HCV)-associated membranoproliferative glomerulonephritis (MPGN) in the kidney transplant may lead to continuous graft deterioration and the need for further renal replacement therapy. The novel direct acting antiviral agents (DAAs) allow a highly effective and interferon-free treatment option for chronic HCV infected patients. Data on the therapeutic safety and efficacy in HCV infected renal transplant patients are sparse, especially for patients with severe renal impairment...
