Disruption of the vif gene of human immunodeficiency virus (HIV) type 1 affects virus infectivity to various degrees, depending on the T-cell line used. We have concentrated our studies on true phenotypic Vif- mutant particles produced from CEMx174 o

The mechanisms of CD4 depletion and hyporesponsiveness during human immunodeficiency virus (HIV) infection are still unknown. Given the ability of superantigens to stimulate a higher number of lymphocytes than conventional antigens, they may play a m

The cytopathic effect of HIV-1 and HIV-2 in CD4+ lymphocytes has been shown to be associated with apoptosis or programmed cell death. Using different experimental conditions, we demonstrate here that apoptosis is triggered by cell membrane expression

One of the difficulties in understanding the complex pathology of human immunodeficiency virus (HIV) infection is to explain the progressive depletion of the CD4 helper T cell population and consequently the destruction of the immune system. Although

An in vitro system for production of hepatitis B virus (HBV) was established by infection of human hepatoma (HepG2) cells. HBV particles obtained from the serum of a chronic hepatitis B surface antigen (subtype ad) carrier were used to inoculate HepG

The expression of the preS1 antigen of hepatitis B virus in sera from chronic HBsAg carriers was studied using a specific monoclonal antibody F35.25 in an original, double-immunoradiometric assay. The antibody F35.25 recognized an epitope located bet

The relation between preS1 antigen/antibody system and different phases of hepatitis B virus infection were studied in 425 serum samples from 50 hepatitis B patients before, during and after antiviral therapy using interferon alone or in combination

The 8E5 clonal cell line, derived from HIV-1-infected CEM cells, carries a single, reverse transcriptase (RT)-defective copy of an integrated HIV genome. The absence of RT production is a consequence of a frame shift in the pol gene, due to the addit
