MHC class I multimers
T lymphocytes play a key role in the immune response to both foreign and self peptide antigens, which they recognize in combination with MHC molecules. In the past it has been difficult to analyse objectively the specificity, frequency and intensity of T cell responses. The recent application of fluorescent-labelled MHC class I multimers, however, has provided a powerful experimental approach t...
متن کاملHLA Class I and Class II Genes Distribution of the Sistanis in Iran
Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...
متن کاملA contig map of the Mhc class I genomic region in the zebrafish reveals ancient synteny.
In contrast to the human and mouse Mhc, in which the clusters of class I and class II loci reside in close vicinity to one another, in the zebrafish, Danio rerio, they are found in different linkage groups. Chromosome walking using BAC (bacterial artificial chromosome) and PAC (P1 artificial chromosome) clones reveals the zebrafish class I region to occupy a segment of approximately 450 kb and ...
متن کاملHuman Papillomavirus and Cancer - Immunological Consequences of MHC Class I Down-Regulation
Few studies have been conducted on the causative factors associated with the development of cancer. Infection by high risk human papillomaviruses (HPVs) have been implicated as causative agents in a variety of cancers. HPV is capable of evading immune system and establishing persistent infections. Prolonged infection and lesion maintenance are associated with higher risk of neoplastic progressi...
متن کاملThe MHC of the duck (Anas platyrhynchos) contains five differentially expressed class I genes.
MHC class I proteins mediate a variety of functions in antiviral defense. In humans and mice, three MHC class I loci each contribute one or two alleles and each can present a wide variety of peptide Ags. In contrast, many lower vertebrates appear to use a single MHC class I locus. Previously we showed that a single locus was predominantly expressed in the mallard duck (Anas platyrhynchos) and t...
