Detection of Herpes Simplex Virus Antibodies Using the Whole Virus and Recombinant gD

Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...

Identification of Aptamer-Binding Sites in Hepatitis C Virus Envelope Glycoprotein E2

Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...

Construction of Recombinant Bacmid DNA Encoding Newcastle Disease Virus (NDV) Fusion Protein Gene

Background and Aims: Newcastle disease virus (NDV) is one of the major pathogen in poultry. Vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. F gene open reading frame (ORF) from NDV is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. The F glycoprotein on the surf...

In silico comparison of Iranian HIV -1 envelop glycoprotein with five nearby countries

HIV-1 envelope (env) glycoprotein mediates an important role in entry of the virus into the susceptible target cells. As env glycoprotein of HIV-1 is highly variable in the different geographical regions, in the present study, different properties of this protein in Iran are compared with five nearby countries. The sequences of HIV-1 env glycoproteins of Iran, Afghanistan, Russia, Turkey, Pakis...
