Programmed death-1 (PD-1), upon engagement by its ligands, programmed death ligand-1 (PD-L1) and programmed death ligand-2 (PD-L2), provides signals that attenuate adaptive immune responses. Here we describe the identification of the Pekin duck PD-L2 (duPD-L2) and its gene structure. The duPD-L2 cDNA encodes a 321 amino acid protein that has an amino acid identity of 76% and 35% with chicken and human PD-L2, respectively. Mapping of the duPD-L2 cDNA with duck genomic sequences revealed an exonic structure similar to that of the human P dcd1lg2 gene...

OBJECTIVES: A small subset of patients treated with immune checkpoint inhibitors manifest atypical patterns of response, the so-called pseudoprogression (PP) and hyperprogression (HP). Their prevalence in urothelial (UC) and renal cancer (RCC) remains, to date, mostly uninvestigated. Therefore, we aimed to provide a summary of the current knowledge about PP and HP during immune checkpoint inhibitor therapy in UC and RCC patients. METHODS AND MATERIALS: A systematic medline/pubmed© literature search was performed...

Solid organ transplantation is the treatment of choice for patients with end-stage organ dysfunction. Despite improvements in short-term outcome, long-term outcome is suboptimal due to the increased morbidity and mortality associated with the toxicity of immunosuppressive regimens and chronic rejection (1-5). As such, the attention of the transplant community has focused on the development of novel therapeutic strategies to achieve allograft tolerance, a state whereby the immune system of the recipient can be re-educated to accept the allograft, averting the need for long-term immunosuppression...

Malignant Rhabdoid Tumor (MRT) is a rare and highly aggressive malignancy primarily affecting infants and young children. The most common anatomic locations are the central nervous system (AT/RT), the kidneys (RTK) and other soft tissues (eMRT). The genetic origin of this disease is linked to mutations in SMARCB1, a gene encoding a core subunit of the SWI/SNF chromatin-remodeling complex. Areas covered: Conventional multimodal treatment may offer a significant survival benefit to certain patients. It remains to be determined, however, which patients will prove resistant to chemotherapy and need novel therapeutic approaches...

BACKGROUND: The cytokine interleukin-18 was originally identified as an interferon-γ-inducing proinflammatory factor; however, there is increasing evidence to suggest that it has non-immunological effects on physiological functions. We previously investigated the potential pathophysiological relationship between interleukin-18 and dyslipidemia, non-alcoholic fatty liver disease, and non-alcoholic steatohepatitis, and suggested interleukin-18 as a possible novel treatment for not only these diseases but also for cancer immunotherapy...

BACKGROUND: Immuno-oncology and cancer immunotherapies are areas of intense research. The numbers and locations of CD8+ tumor-infiltrating lymphocytes (TILs) are important measures of the immune response to cancer with prognostic, pharmacodynamic, and predictive potential. We describe the development, validation, and application of advanced image analysis methods to characterize multiple immunohistochemistry-derived CD8 parameters in clinical and nonclinical tumor tissues. METHODS: Commercial resection tumors from nine cancer types, and paired screening/on-drug biopsies of non-small-cell lung carcinoma (NSCLC) patients enrolled in a phase 1/2 clinical trial investigating the PD-L1 antibody therapy durvalumab (NCT01693562), were immunostained for CD8...

Recently, various immuno-PET tracers based on monoclonal antibodies (mAbs), engineered scaffold proteins and peptides were developed to target either programmed cell death protein 1 (PD-1) or programmed cell death ligand 1 (PD-L1), showing promise in assessment of immune checkpoints. We sought to develop an immunotherapeutic agent-based PET probe that enable real-time assessment of PD-L1 expression and evaluation of antibody drug biodistribution to select eligible candidates for anti-PD-1/PD-L1 immunotherapies...

Hepatitis E virus (HEV) is the most common cause of viral hepatitis worldwide. Genotypes 1 and 2 (GT1 and GT2) are mainly present in developing countries, while GT3 and GT4 are prevalent in developed and high-income countries. In the majority of cases, HEV causes a self-limiting hepatitis. GT3 and GT4 can be responsible for a chronic hepatitis that can lead to cirrhosis in immunocompromized patients, i.e. solid-organ- and stem-cell-transplant-patients, human immunodeficiency virus-infected patients, and patients receiving chemotherapy or immunotherapy...

von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome caused by mutations in the VHL tumor-suppressor gene, leading to the dysregulation of many hypoxia-induced genes. Affected individuals are at increased risk of developing recurrent and bilateral kidney cysts and dysplastic lesions which may progress to clear cell renal cell carcinoma (ccRCC). Following the eponymous VHL gene inactivation, ccRCCs evolve through additional genetic alterations, resulting in both intratumor and intertumor heterogeneity...

BACKGROUND: The successful development of immunosuppressive agents has paradoxically led to an era in which adverse effects of immunosuppression, such as infections and cancer, are now a major concern in solid organ recipients. Nevertheless, the main focus of immune monitoring research remains the identification of rejection. There is currently no clinical tool to assess the net state of immunosuppression or to identify patients at increased risk of infectious complications. METHODS: We report a prospective, longitudinal study in which we conducted detailed phenotyping of over 300 peripheral blood mononuclear cell samples from 45 kidney recipients during the first 24 months posttransplant...

Background: Rabbit antithymocyte globulin (rATG) is the most widely used kidney transplant induction immunotherapy in the United States. It was recently Food and Drug Administration approved for this indication with typical dose recommendations of 1.5 mg/kg for up to 7 days given via a central line. Methods: We theorized that reduced rATG dosing when compared with conventional dosing (6-10.5 mg/kg) is safe and effective, leading to development of a risk-stratified treatment protocol...

Small cell lung cancer (SCLC) is of a highly invasive and metastatic lung cancer subtype and there had not been effective targeted therapies. CD56, a cell surface marker highly expressed on most SCLC, is a promising therapeutic target for treatment of this aggressive cancer. In this study, we generated a novel anti-CD56 antibody named promiximab, characterized by high affinity, internalization and tumor specificity. Then, the promiximab was conjugated with a potent DNA alkylating agent duocarmycin via reduced interchain disulfides to yield the promiximab-Duocarmycin (promiximab-DUBA) conjugates...

Progress in kidney transplant has improved survival while creating challenges. The pool of eligible patients is increasing, but organ supply remains inadequate. Waiting-list issues, adequate pretransplant assessment, judicious use of potent immunotherapy, and management of infections must be considered.

Methicillin resistant Staphylococcus aureus (MRSA) is a representative pathogen that is responsible for a nosocomial infection and considerable yearly mortality rate. Antibiotic resistance provides a great reason for immunotherapy as an alternative strategy to prevent and/or treat the infection. Herein, following the preparation of recombinant penicillin binding protein 2a (r-PBP2a), rabbit polyclonal IgG was purified. Specificity of IgG to r-PBP2a was evaluated by ELISA and western blotting. IgG fraction was prepared by sulfate ammonium precipitation...

EBV-CTL immunotherapy targets EBV antigens expressed by tumor cells in PTLD. Data on outcome of EBV-CTL in pSOT patients are limited. The aim of the study is to describe our experience with allogeneic, third-party EBV-CTL for the treatment of PTLD in pSOT patients in a single tertiary center. Retrospective review was performed of all pSOT patients who received EBV-CTL for PTLD. PTLD was diagnosed using World Health Organization histologic criteria. EBV-CTLs were derived from human leukocyte antigen-typed, EBV-seropositive third-party donors, and cryopreserved and maintained by an accredited national blood transfusion service...

Anticancer drug-induced kidney disease is a problem commonly encountered by nephrologists. The number of medications employed by oncologists causing acute and chronic kidney injury as well as electrolyte and acid-base disturbances has increased significantly over the past several decades. While conventional chemotherapeutic drugs induce a number of kidney lesions, emergence of very effective and well-tolerated targeted therapies and novel immunotherapies has increased the occurrence of drug-induced acute and chronic kidney injury in cancer patients...
