Es obtained with the LTR-specific primers represent a sum of transcripts originating from the host promoter and of viral transcripts, which also contain LTR sequence at their 3' ends. Therefore, the measured ratio corresponds to the equation a+b/b, where `a' is the number of host-viral chimeric transcripts and `b' the number of viral transcripts (see Supplemental text 2). First, we determined this
Vels of viral particles, we speculate that average levels of host-viral chimeric transcripts in these cells exceed those in the two J-Lat cell lines. These results thus suggest that TI plays a key role in primary CD4+ T cells. In J-Lat 9.2 and 15.4 cells, the host-viral chimeric transcripts terminated at the pA site in the 5'LTR, but transcripts initiating at the host promoter and terminating at t

Ns dormant. In contrast, we demonstrated that TI could be counteracted by specific inhibition of the upstream transcription or by cooperative activation of transcription initiation and elongation from the 5'LTR by the viral and host TFs. In the latter scenario, we envision that RNAPII initiating from the viral promoter competes successfully with the RNAPII that is elongating through the 5'LTR. Bec

Ranscription units (Han et al., 2004; Lewinski et al., 2005). In the present work, we extended this knowledge by a detailed analysis of how TI impacts viral transcription in latent cells. Although TI occurs regardless of the orientation of the two promoters, we studied TI phenomenon in two J-Lat cell lines with the same orientation of the host and viral promoters, which allowed us to detect and an
