DNA-mediated immunization of mice with plasmid encoding HBs antigen.
In order to develop an experimental DNA vaccine for the prevention and treatment of hepatitis B virus infection, hepatitis B virus surface antigen (HBsAg) DNA was subcloned into an E. coli-eukaryotic cell shuttle vector and was expressed in the Baculovirus expression system. Intramuscular, intradermal, and intraperitoneal injections of 30 microg of the plasmid DNA expressing HBsAg induced humor...
متن کاملComplement fixing hepatitis B core antigen immune complexes in the liver of patients with HBs antigen positive chronic disease.
One hundred and fifty-two biopsies from serologically HBsAg positive and negative patients with liver disease were studied in immunofluorescence: for the presence of the surface (HBs) and the core (HBc) antigenic determinants foeterminants of the hepatitis B virus, of immunoglobulins and complement (C) deposits, and for the capacity to fix human C. Circumstantial evidence is presented suggestin...
متن کاملHepatitis B Viral DNA Among HBs Antigen Negative Healthy Blood Donors
BACKGROUND Presence of occult hepatitis B infection (OBI) renders HBs antigen (HBsAg) undetectable by ELISA. Therefore it is valuable to evaluate the frequency of OBI among healthy blood donors to improve and perhaps change the strategies of blood screening to reduce the risk of HBV transmission. OBJECTIVES The aim of this study was to determine the presence of HBcAb and HBV DNA among Iranian...
متن کاملHepatitis B virus surface antigen (HBsAg) and antibody (anti-HBs) forming immune complexes in fulminant hepatitis.
This paper reports an unusual pattern of serological HBV markers and the presence of HBsAg/anti-HBs immune complexes in serum samples from two patients with fulminant hepatitis from the Brazilian Western Amazon Basin. The diagnosis was made by both serologic tests and demonstration of antigen/antibody complexes by transmission electron microscopy. Concurrent Delta virus superinfection is also d...
متن کاملLaparoscopical and histological abnormalities of the liver in chronic HBs ag (hepatitis B surface antigen) carriers.
Previously, I have reported the laparoscopical and histological findings of 16 chronic HBs Ag carriers in whom the time of HBV infection could be assumed, HBs Ag in the sera persisted for at least 6 months, and laparoscopy with liver biopsy was performed. In these carriers, no abnormal results of liver function tests were found and early history of hepatitis was unknown. Besides these 16 HBs Ag...
