Splenocytes of the indicated subsets were assessed for LP-BM5 retroviral load. In this real-time qRT-PCR assay, expression of the BM5def and BM5eco viruses was normalized to the expression of β-actin (see Materials and Methods). This pattern of results is representative of one additional experiment for comparisons between all of the cell subsets shown here and for four other experiments comparing uninfected cells to α-Ly6G⁺-depleted CD11b⁺-enriched spleen cells obtained from 5-w.p.i. LP-BM5-infected B6 w.t. mice. *, P < 0.05, and **, P < 0.01.
