We present a case of diarrhea secondary to biopsy-proven adenovirus (ADV) infection after autologous peripheral hematopoietic stem cell transplant for multiple myeloma. The patient had a negative plasma polymerase chain reaction for ADV and a dramatic clinical response to low-dose cidofovir. To our knowledge, this is the first report in an adult hematopoietic stem cell recipient of the use of l...
Adenovirus (AdV) respiratory infections have usually been associated with species B, C, and E. In this study, we detected 9.4% of AdVs by PCR in 500 nasal swabs from 319 children with influenza-like symptoms. AdV typing by PCR with specific probes showed species C, B, and F as well as coinfection with two species. Coinfection with two AdV species and the presence of species F in respiratory sam...
Nitric oxide (NO) functions principally as a diffusible paracrine effector. The exception is in cardiomyocytes where both NO synthases (NOS) and target proteins coexist, allowing NO to work in an autocrine/intracrine fashion. However, the most abundant myocyte isoform (NOS3) is far more expressed in vascular endothelium; thus, the in vivo contribution of myocyte-NOS3 remains less clear. The pre...
Despite lingering safety concerns [1] and potential restrictions imposed by the host immune response, including the innate immune pattern recognition receptors (PRR), replicationdefective and conditionally replicating human and nonhuman adenovirus (AdV) vectors continue to be a favorite vehicle for short-term (e.g., vaccine) and long-term gene delivery. This is due in part to several desirable ...
Dendritic cells (DCs) are capable of presenting tumor-associated antigens and subsequently play an essential role in T-cell activation. The aim of this study was to develop an efficient method for gene transfer into DCs. These genetically transduced DCs can then be used as potent inducers of specific cell-mediated immune response. When compared with physical methods for gene transfer (lipofecti...
Adenoviral (ADV) gene therapy with the thymidine kinase gene (TK) under control of the Rous sarcoma virus (RSV) promotor followed by the administration of acyclovir leads to replication errors in transcription and to cell death. This concept of ADV-RSV-TK has been established for the treatment of ovarian cancer cells. The purpose of this investigation was to clarify whether cell death after ADV...
Prophylactic antiviral therapy is essential for lymphoma patients with high baseline HBV DNA who undergo cytotoxic chemotherapy. However, there are limited data on the optimal options. The present study was designed to compare the efficacy of prophylactic lamivudine (LAM) with lamivudine plus adefovir dipivoxil (LAM+ADV) in preventing hepatitis B virus (HBV) reactivation in lymphoma with, pre-c...
Replication-defective adenovirus (ADV) vectors represent a promising potential platform for the development of a vaccine for AIDS. Although this vector is typically administered intramuscularly, it would be desirable to induce mucosal immunity by delivery through alternative routes. In this study, the immune response and biodistribution of ADV vectors delivered by different routes were evaluate...
The aim of this study was to search for new antiviral agents from Chinese herbal medicine. Pure flavonoids and aqueous extracts of Caesalpinia pulcherrima Swartz were used in experiments to test their influence on a series of viruses, namely herpesviruses (HSV-1, HSV-2) and adenoviruses (ADV-3, ADV-8, ADV-11). The EC50 was defined as the concentration required to achieve 50% protection against ...
Adenoviruses (AdVs) broadly infect vertebrate hosts, including a variety of nonhuman primates (NHPs). In the present study, we identified AdVs in NHPs living in their natural habitats, and through the combination of phylogenetic analyses and information on the habitats and epidemiological settings, we detected possible horizontal transmission events between NHPs and humans. Wild NHPs were analy...
