Oncolytic viral therapy, which makes use of replication-competent lytic viruses, has emerged as a promising modality to treat malignancies. It has shown meaningful outcomes in both solid tumor and hematologic malignancies. Advancements during the last decade, mainly genetic engineering of oncolytic viruses have resulted in improved specificity and efficacy of oncolytic viruses in cancer therape...
background: herpes simplex viruses (hsv) are human pathogens that establish lytic and latent infections. reactivation from latency occurs intermittently, which represents a life-long source for recurrent infection. the role of immune factors in the control of recurrent symptomatic hsv lesions is complex and the exact role of cytokines remains unclear. objective: to assess the levels of tumor ne...
Introduction: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS). It is an Auto immune disease whose cause is still unknown though some factors can be named as its cause such as genetics, geographic element and viral agents. HSV is among the infection agents that may be involved in pathogenesis of MS. The aim of this study was to use a new technique called lo...
Background and Objectives: Viral infections are a major problem for transplant recipients. Reactivation of viruses is associated with the use of strong immunosuppressive drugs. Herpes simplex virus infections in renal transplant patients may become severe without treatment. Although the prevalence and role of herpes simplex viruses 1 and 2 in bone marrow and lung recipients are well known; howe...
Herpes simplex virus (HSV) and varicella-zoster virus (VZV) are both human alpha-herpes viruses. They are capable of establishing latent infections in neural tissues and to reactive from these sites, determining the clinical features of the disease (primary infection versus recurrences). Infections with these viruses are common; an increased number of elderly and immunocompromised individuals w...
Several complications attributed with Herpes virus related infections and the emergence of drug resistant viruses prompt scientists to search for new drugs. Several terpenoids and coumarins have shown anti HSV effects while no sesquiterpene coumarin have been previously tested for HSV treatment. Three sesquiterpene coumarins [badrakemin acetate (1), kellerin (2) and samarcandin diasteromer (3) ...
The sensitization of herpes simplex virus by immunoglobulin G (IgG) antibodies was studied. Although herpes simplex virus sensitized by IgG could not be neutralized by IgA antibodies known to neutralize a similar number of unsensitized viruses, this protection could be overcome by larger amounts of IgA antibodies. This suggests that the effective neutralization of herpes simplex virus in ocular...
Normal bone marrow cells from a donor positive for herpes simplex virus were transformed with Epstein-Barr virus. The resulting lymphoblastoid cell line has secreted immunoglobulin G1 of the kappa type continuously for 2 years. This immunoglobulin, detected both on the cell surface and in the cytoplasm, reacts with cells infected with herpes simplex virus. It defines an antigen that comigrates ...
Ribonuclease is a highly active inhibitor of vaccinia virus multiplication in vitro in the chorioallantoic membrane removed from embryonated chicken eggs. It is also a highly active inhibitor of pock formation by vaccinia and herpes simplex viruses on the chorioallantoic membrane in vivo. Marked inhibitory effects were obtained with 12.5 microg. of RNase. However, complete inhibition was not ob...
