Nonrandom distribution of hepatitis C virus quasispecies in plasma and peripheral blood mononuclear cell subsets.

ABSTRACT: The existence of an extrahepatic reservoir of hepatitis C virus (HCV) is suggested by differences in quasispecies composition between the liver, peripheral blood mononuclear cells, and serum. We studied HCV RNA compartmentalization in the plasma of nine patients, in CD19(+), CD8(+), and CD4(+) positively selected cells, and also in the negatively selected cell fraction (NF). HCV RNA was detected in all plasma samples, in seven of nine CD19(+), three of eight CD8(+), and one of nine CD4(+) cell samples, and in seven of eight NF cells. Cloning and sequencing of HVR1 in two patients showed a sequence grouping: quasispecies from a given compartment (all studied compartments for one patient and CD8(+) and NF for the other) were statistically more genetically like each other than like quasispeci
