S, exactly where a period of dysregulated gene expression happens (ten, 12, 32, 35), HCMV-infected monocytes failed to express the well-characterized IE1- and pp65-specific RNAs associated with lytic infection (Fig. 1D, lanes 33 to 40 and 41 to 48). Simply because IE1 (UL123)-specific and pp65 (UL83)-specific transcripts have been shown to be expressed at substantially higher levels in the course of productive infection (36), their absence suggests the establishment of experimental latency throughout the six-day time course of infection. Further analysis of TB40/E-infected monocytes was performed, as recent work has demonstrated HCMV to possess a broader transcriptional profile throughout latency (32). Analysis of TB40/E-infected monocytes through short-term experimental latency identified the expression of RNA2.7 (Fig. 1D, lanes 17 to 24), a extended noncoding RNA identified throughout long-term (18 days) infection of monocytes (32), and also the noncoding transcripts RNA1.2 and RNA4.9 (information not shown). These findings are constant with RNA sequencing data from TB40/E-infected monocytes (V. M. Noriega and D. Tortorella, unpublished data). Interestingly, the RL8A and RL9A transcripts, that are positioned downstream of RNA1.two, were not detected in TB40/E-infected monocytes (Fig. 1D, lanes 49 to 56; also information not shown), supporting the model of selective transcription of viral genes during latency. Strikingly, analysis of some well-characterized viral immune evasion genes (16) revealed that US3 (Fig. 1D, lanes 25 to 32), US2, UL111A (vIL-10), and UL32 (information not shown) have been expressed exclusively by TB40/E-infected monocytes, whilst these latently infected monocytes tested unfavorable for US11 (information not shown). The selective expression of the viral immune evasion genes could play a role in limiting T cell activation.
