RESUMO

Inoculation of adult mice with Friend virus complex usually induces rapid viremia and erythroleukemia, resulting in death in 1 to 3 months. In certain mouse strains, a single host gene, Rfv3, controls the ability to mount a virus-specific neutralizing antibody response which results in elimination of viremia. In this study, microsatellite markers were used to localize the Rfv3 gene to a 20-centimorgan region of mouse chromosome 15 unlinked to immunoglobulin loci, T-cell receptor loci, or the major histocompatibility complex. Potential candidate genes for Rfv3 are several genes expressed in cells of the immune system and previously mapped to the same region, including a T-cell antigen gene, Ly6, and three cytokine receptor genes, IL2rb, IL3rb1, and IL3rb2.
