Murine cytotoxic T lymphocyte recognition of individual influenza virus proteins. High frequency of nonresponder MHC class I alleles

We determined the MHC restriction of CTL responses to five individual influenza virus proteins. Four viral proteins failed to be recognized in conjunction with three of the five class I alleles of the H-2k and H-2d haplotypes, while the fifth was recognized only in conjunction with a single allele. This indicates that there is a significant chance that a given class I allele will be associated ...

Differences in antigen presentation to MHC class I-and class II- restricted influenza virus-specific cytolytic T lymphocyte clones

We have examined requirements for antigen presentation to a panel of MHC class I-and class II-restricted, influenza virus-specific CTL clones by controlling the form of virus presented on the target cell surface. Both H-2K/D- and I region-restricted CTL recognize target cells exposed to infectious virus, but only the I region-restricted clones efficiently lysed histocompatible target cells puls...

Prediction of Cytotoxic T Cell (MHC Class I) epitopes

NLRC5 deficiency selectively impairs MHC class I- dependent lymphocyte killing by cytotoxic T cells.

Nucleotide-binding oligomerization domain-like receptors (NLRs) are intracellular proteins involved in innate-driven inflammatory responses. The function of the family member NLR caspase recruitment domain containing protein 5 (NLRC5) remains a matter of debate, particularly with respect to NF-κB activation, type I IFN, and MHC I expression. To address the role of NLRC5, we generated Nlrc5-defi...

Class I major histocompatibility complex-restricted T lymphocyte recognition of the influenza hemagglutinin. Overlap between class I cytotoxic T lymphocytes and antibody sites

The influenza hemagglutinin is a critical regulator of disease expression during influenza virus infection and serves as a major target for the host immune response to this pathogen. In this report, we have analyzed an immunodominant site on the hemagglutinin (residues 202-221) recognized by murine class I MHC-restricted T lymphocytes. This analysis has revealed evidence for the duplication of ...
