چکیده

Human cytotoxic T cells specific for influenza A virus were tested for recognition of each of the ten influenza A virus proteins expressed in target cells using recombinant vaccinia viruses. They recognized the matrix M1, polymerase PB2, and nucleoproteins of influenza virus in association with MHC class I antigens. These internal viral proteins were seen by CTL in conjunction with one or more of the available dependent HLA gene products. There was no detectable recognition of influenza virus surface glycoproteins in target cells.

Molecular Identification of Pre-Existing Immunityin Human against H9N2 Influenza Viruses Using HLA-A*0201 Binding Peptides

Background and Aims: The contribution genetic and antigenic diversity of H9N2 influenza viruses in evading from immune responses, cytotoxic T lymphocytes (CTL) epitopes in hemagglutinin (HA) protein restricted by HLA binding peptides was identified. Materials and Methods: Phylogenetic analyses were carried out for all of full length HA and deduced amino acid sequences of H9N2 viruses available ...

A broad cytotoxic T lymphocyte response to influenza type B virus presented by multiple HLA molecules.

The HLA restriction and epitope specificity of cytotoxic T lymphocytes (CTL) involved in recovery from influenza type B infection have not been extensively characterized. Here lymphocytes obtained from a healthy individual contained virus-specific CTL restricted by class I HLA molecules, HLA-A1, A2, B7 and B8, and the class II HLA molecules, HLA-DR1 and DR3. Four conserved viral epitopes were p...

Brief Definitive Report Influenza Virus Subtype-specific Cytotoxic T Lymphocytes Lyse Target Cells Coated with a Protein Produced in E. Coli

Virus-specific cytotoxic T cells (CTL) recognize viral antigen in conjunction with products of genes of the major histocompatibility complex (MHC) (1); however, the nature of the viral antigen(s) recognized by specific CTL is not clear, identification of viral determinant(s) recognized by CTL is an important issue; however, it has been difficult to demonstrate CTL recognition of target cells ex...

Influenza virus subtype-specific cytotoxic T lymphocytes lyse target cells coated with a protein produced in E. coli

We have tested the ability of the c13 protein, which is a hybrid protein of the first 81 amino acids of the viral nonstructural protein (NS1) and the HA2 subunit of viral hemagglutination produced in E. coli, to render target cells susceptible to the lytic activity of influenza virus-specific cytotoxic T lymphocytes (CTL). The results showed that P815 cells coated with c13 protein were lysed by...

Contribution of  Virus-specific CD8+ Cytotoxic T Cells to Virus Clearance or Pathologic Manifestations of Influenza Virus Infection in a T Cell Receptor Transgenic Mouse Model

The ability of influenza virus to evade immune surveillance by neutralizing antibodies (Abs) directed against its variable surface antigens provides a challenge to the development of effective vaccines. CD8+ cytotoxic T lymphocytes (CTLs) restricted by class I major histocompatibility complex molecules are important in establishing immunity to influenza virus because they recognize internal vir...
