As discussed above, no satisfying therapeutic options exist for treatment of locally advanced and metastatic pancreatic cancer. The prognosis is dismal with a six-month progression-free survival of approximately 50% and a median survival of about 11 months [5].. The first open, non-randomized clinical trial with ParvOryx, referred to as ParvOryx01, evaluated safety and tolerability as well as antitumor activity and clinical efficacy in patients with progressive primary or recurrent glioblastoma multiforme (GBM). ParvOryx01 was completed in May 2015 [18]. The investigated doses ranged between 1E06 and 5E09 pfu. They were administered as combination of either multiple intravenous infusions or a single intratumoral injection and multifocal intracerebral injections at the end of tumor resection surgery. As in the current trial, the intravenous dose was divided into equal fractions which were given on consecutive days. The interval between the first administration and surgery with subsequent ...

Our model are DNA-based viruses, mostly papillomaviruses. Papillomaviruses (PVs) are part and parcel of the skin microbiota in all mammals, and ancestral PVs already infected the ancestral bony vertebrates. The vast majority of PV infections in humans as well as in other animals are asymptomatic and virtually all individuals get infected very early in life. Yet, some PVs can trigger benign proliferations and cause warts in humans and in many other animals, transmitted by simple contact or by sexual route. Further, a handful of closely related PVs are responsible for ca. 5% of all human cancers, essentially in anogenital and oropharyngeal sites. Despite intense research, many questions remain open regarding the evolutionary connection between PV infections and cancer.. ...
X-linked severe combined immunodeficiency (XSCID) is caused by a genetic mutation within the common gamma chain (γc), an essential component of the cytokine receptors for interleukin (IL)-2, IL-4, IL-7, IL-9, IL-15, and IL-21. XSCID patients are most commonly treated with bone marrow transplants (BMT) to restore systemic immune function. However, BMT-XSCID humans and dogs remain at an increased risk for development of cutaneous papillomavirus (PV) infections and their associated neoplasms, most typically cutaneous papillomas. Since basal keratinocytes are the target cell for the initial PV infection, we wanted to determine if canine XSCID keratinocytes have a diminished antiviral cytokine response to poly(dA:dT) and canine papillomavirus-2 (CPV-2) upon initial infection. We performed quantitative RT-PCR for antiviral cytokines and downstream interferon stimulated genes (ISG) on poly(dA:dT) stimulated and CPV-2 infected monolayer keratinocyte cultures derived from XSCID and normal control dogs. We found
p53 and the Retinoblastoma protein (pRb) are two oncosuppressive proteins whose loss of function is linked to the development of many cancers. Both of them play a central role in the regulation of both cell cycle and apoptosis. Different observations have led to a paradigm in which p53 and pRb can regulate each other, pRb playing an important role in the outcome-growth arrest versus apoptosis-of p53 activation.

Researchers analyzed genetic differences between mouse and human immune systems in order to understand why certain experiments work in mice but not humans and vice versa.
The human immune system consists of tissues, organs and different cell types all dispersed throughout the body. Immune cells provide protection against invading organisms, but under normal circumstances they know not to attack the bodys own healthy cells. Lymphocytic leukemia is a cancer affecting the T-lymphocytes or T-cells, and myelogenous leukemia in an abnormal proliferation of the granulocytes--neutrophils, basophils and eosinophils.

Press Release issued Feb 7, 2017: The field of oncolytic viruses was quite dormant in the first decade of the 2000s, characterized by slow clinical progress due to hypercautiousness and low, albeit steady, investments. The takeover of BioVex by Amgen in late 2011, worth up to US$ 1 bln, has woken up the field and became a game changer together with the 2015 approval of the first oncolytic virus Imlygic developed by BioVex in regulated markets. In addition, it was increasingly recognized that oncolytic viruses not only were able to directly lyse cancer cells, but they also freed tumor specific neoantigens, indirectly acting as a cancer vaccine.
According to data from a phase I study, the oncolytic virus Delta-24-RGD can infect, replicate, and kill glioma cells in patients.
La Jolla Institute scientists provide new insights into how so-called CD4 cytotoxic T cells arise in humans and thus could facilitate improved vaccine design.
Papillomas or warts are easily recognized skin or mucous membrane tumors. They are common in wild species and are particularly well known in deer (Cosgrove and Fay 1981; Sundberg and Nielson 1981). Most of these tumors are caused by papillomaviruses (PVs). Tumors can become quite large and numerous and persist for prolonged periods, but they usually regress, providing the individual with long-term immunity to future infections. Occasionally, the tumors will progress to squamous cell carcinoma, adenosquamous carcinoma, or sebaceous carcinoma that will eventually kill the host if not treated. Specific mucosotropic PV types and those infecting immunodeficient individuals are prone to induce malignancies. Virtually all mammalian species are hosts for one of more PV. This chapter provides an overview of PV infections in mammals ...

We have presented several lines of evidence that the papillomavirus minor capsid protein mediates the endosomal escape of the viral genome. A C-terminal 23-amino-acid peptide from the L2 protein was identified that is essential for transit of the viral DNA across the endosomal membrane during papillomavirus infection. This peptide is also highly cytotoxic to bacteria, fungi, and mammalian cells after exogenous application due to membrane depolarization and permeabilization and induces the integration of GFP fusion proteins and full-length L2 protein into cellular membranes when expressed in mammalian cells, eventually resulting in cell death. Since the full-length L2 protein but not C-terminally mutated L2 nor L1 protein integrated into cellular membranes, an artificial effect of the observations with peptides and fusion proteins can be excluded. These critical functions render this peptide sequence indispensable for PV infection. The activity of this peptide is highest at modestly acidic pH, ...

Proteomic analysis revealed the identity of proteins that were significantly modulated by the treatment with wild-type TP53 and the cytotoxic chemotherapy SN38. In particular, galectin-1 was found to be negatively regulated by transfection with TP53 and further down-regulated by SN38. Expression level changes were confirmed by Western blot. Subsequent analysis of several high-grade glioma cell lines demonstrated very high levels of galectin-1, regardless if the cell lines contained mutant or wild-type TP53. High ...

Blood, donated by asymptomatic donors, may contain and transmit parvovirus B19. To investigate the dynamics of parvovirus viraemia in asymptomatic blood donors, we studied the amounts of parvovirus DNA in pools of donor plasma, the prevalence of parvovirus antibodies among blood donors in relation to age, and the seasonal and year-to-year variation of the incidence of parvovirus infection in The Netherlands. The incidence of parvovirus infection follows a seasonal cycle and a cycle of several years. Among Dutch blood donors the incidence was estimated to be 0·56% per year. Forty seven out of 100 pools of 5000 plasma donations tested positive for parvovirus DNA. We inferred that the course of viraemia in asymptomatic donors shows a short peak (,109 copies parvovirus DNA/ml), followed by viraemia below 106 copies/ml for about 2 weeks.. ...
Picornaviruses (PV) include human rhinovirus (HRV), the primary cause of the common cold, and the enteroviruses (EV), which cause serious diseases such as poliomyelitis, meningoencephalitis, and systemic neonatal disease. Although no compounds for PV infections have been approved in the United States, pirodavir was one of the most promising capsid-binding compounds to show efficacy in human clinical trials for chemoprophylaxis of the common cold. Susceptibility to hydrolysis precluded its use as an oral agent. We have developed orally bioavailable pyridazinyl oxime ethers that are as potent as pirodavir. Compounds BTA39 and BTA188 inhibited a total of 56 HRV laboratory strains and three clinical isolates as determined by neutral red uptake assay. At concentrations of |100|nM, BTA39 inhibited 69% of the HRV serotypes and isolates evaluated, BTA188 inhibited 75%, and pirodavir inhibited 59% of the serotypes and isolates. The 50% inhibitory concentrations (IC50s) for the two compounds ranged from 0.5 nM
