The major histocompatibility complex (MHC) class I molecules expressed at the cell surface are associated with a large number of different peptides so that the density of a given MHC-peptide complex is relatively low. Here we describe the properties of MHC class I molecules genetically attached to a single antigenic peptide. Cells expressing these fusion(More)
Chronic infection with hepatitis C virus (HCV) is a major public health problem, with nearly 170 million infected individuals worldwide. Current treatment for chronic infection is a combination of pegylated IFN-α2 and ribavirin (RBV); however, this treatment is effective in fewer than 50% of patients infected with HCV genotype 1 or 4. Recent studies(More)
Light satellite DNA components present in species belonging to the genus Mus and to related murids were studied using the Southern blot technique. The results show species variations in both the amount and periodic structure of the repeating units, which suggests that families of related higher-order repeats developed in a common ancestor and were then(More)
Chronic infection perturbs immune homeostasis. While prior studies have reported dysregulation of effector and memory cells, little is known about the effects on naïve T cell populations. We performed a cross-sectional study of chronic hepatitis C (cHCV) patients using tetramer-associated magnetic enrichment to study antigen-specific inexperienced CD8(+) T(More)
Biochemical experiments, animal models, and observational studies in humans all support a role of dipeptidyl peptidase 4 (DPP4) in the N-terminal truncation of CXCL10, which results in the generation of an antagonist form of the chemokine that limits T-cell and NK cell migration. Motivated by the ability to regulate lymphocyte trafficking in vivo, we(More)
