Antibodies and CD8+ T cells are complementary and essential for natural resistance to a highly lethal cytopathic virus.

Memory CD8+ T cells specific for a single immunodominant or subdominant determinant induced by peptide-dendritic cell immunization protect from an acute lethal viral disease.

The antigens recognized by individual CD8(+) T cells are small peptides bound to major histocompatibility complex (MHC) class I molecules. The CD8(+) T cell response to a virus is restricted to several peptides, and the magnitudes of the effector as well as memory phases of the response to the individual peptides are generally hierarchical. The peptide eliciting a stronger response is called im...

Direct CD28 costimulation is required for CD8+ T cell-mediated resistance to an acute viral disease in a natural host.

Previous studies have suggested that, differing from model Ags, viruses that replicate extensively in the host still induce normal CD8+ T cell responses in the absence of CD28 costimulation. Because these studies were performed with viruses that do not normally cause acute disease, an important remaining question is whether CD28 costimulation is required for CD8+ T cell-mediated resistance to w...

Buthionine Sulfoximine Inhibits Cytopathic Effects and Apoptosis Induced by Infection with AIK-HDC Strain of Measles Virus

Measles virus (MV) is a highly contagious agent which causes a major health problem in developing countries. We studied the effect of buthionine sulfoximine (BSO) on the replication of an AIK-HDC strain of MV and its induced apoptosis in Vero cell lines. Methods: In this study, toxicity of BSO on Vero cells was investigated first, resulted in determination of sub-lethal or non-toxic concentrati...

The Relative Levels of Neutralizing and Precipitating Antibodies Against Infectious Bursal Disease Virus and Their Correlation with Resistance to a Highly Virulent Challenge Strain

Resistance to and Recovery from Lethal Influenza Virus Infection in B Lymphocyte–deficient Mice

In the adaptive immune response to most viruses, both the cellular and humoral arms of the immune system play complementary roles in eliminating virus and virus-infected cells and in promoting recovery. To evaluate the relative contribution of CD4+ and CD8+ effector T lymphocytes in virus clearance and recovery, we have examined the host response to lethal type A influenza virus infection in B ...
