Pathogenesis of viral encephalitis: Demonstration of viral antigen(s) in the brain endothelium
Acta Neuropathologica, 1983One of the enigmas in the pathogenesis of inflammation is why the white cells adhere to the endothelium. In trying to define the pathogenic mechanism, we carried out experiments on ferrets infected with an SSPE strain of measles virus. Using immunoperoxidase labeling techniques, viral antigens were demonstrated on the luminal surface and in the ...

Viral diagnosis by antigen detection techniques
Clinical and Diagnostic Virology, 1996Diagnosis of viral infections can be obtained in the early stages of a disease by detection of viral antigens directly in the clinical specimen. This has become an important tool for rapid virus diagnosis.Antigens produced during virus infections can be detected either in cells collected from the site of infection by immunohistological investigation or

Australia Antigen and Viral Hepatitis in Drug Abusers
Archives of Internal Medicine, 1971Much evidence supports the hypothesis that Australia antigen (Au[1]) causes viral hepatitis. We found Au(1) in 30 of 43 drug abusers with hepatitis (69.8%), a similar frequency to posttransfusion hepatitis (56.3%), but different from infectious hepatitis (30.1%). There were no distinctive histologic features in liver biopsies from drug abusers.

Antigenic Modulation: A Mechanism of Viral Persistence
1983Publisher Summary This chapter discusses experiments conducted to investigate the ability of antibody to measles virus to alter the expression of viral antigens on and within infected cells. The monoclonal antibody directed against the measles virus hemagglutinin (HA) used in these experiments bound to the surfaces of infected HeLa cells. As a result,

Detection of Viral Antigens and Antibodies
1989Serological techniques have been the most widely used means of diagnosing viral diseases for years, but several of their shortcomings have shifted the emphasis toward the direct detection of antigens. Nevertheless, serological testing is still useful if it is impractical or impossible to demonstrate the presence of a viral antigen, e.g., measles virus,

Detection of viral antigen in the endolymphatic sac
Oto-Rhino-Laryngology, 1996A study was devised to determine whether or not any immune defense mechanism is present when a virus invades the human endolymphatic sac (ES). The ES was removed from 14 fresh autopsy cases having no known pre-mortem diseases in the middle and inner ears. Specimens were then examined for viral antigens including herpes simplex (HSV) type 1 and 2, mumps
