Characterization of tumor cell lines derived from murine gammaherpesvirus-68-infected mice.

摘要

Cell lines were derived from mice with murine gammaherpesvirus-68 (MHV-68)-associated lymphoproliferative disease. Four were of an ambiguous phenotype and were MHV-68 negative. One, S11, was a B lymphocyte that contained MHV-68 genomes in both linear and episomal forms and released virus. The line was clonable and grew into tumors in nude mice. This is the first naturally occurring MHV-68-positive B-cell line to be generated, and it will be an invaluable tool for the study of MHV-68 latency.
