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
Ormed using NorthernMax kit (Ambion) according to the manufacturer's instructions. The probes were amplified from cDNA synthesized with MMLV reverse transcriptase (Invitrogen). PCR products were labeled with BioNick Labelling System (Invitrogen). Stimulation of J-Lat cells and detection of activated cells by flow cytometry Tat protein was expressed from pCDNA3 vector using electroporation of 107 J
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
T the level of gene expression act cooperatively to establish and maintain HIV latency. In conclusion, our study reveals that TI represents a key mechanism that antagonizes proviral gene expression to promote the latency of HIV. Furthermore, it demonstrates several means that could be used to counteract TI for reactivating latent HIV. Future mechanistic studies linking TI and other transcriptional
Ction conferred by Hepatitis A immune globulin, we tested the efficacy of a single injection (20mg/kg) of four anti-HIV-1 neutralizing monoclonal antibodies (MAbs) (VRC01, VRC01-LS, 3BNC117, and 10-10749-12) in blocking repeated weekly low dose virus challenges of the clade B SHIVAD8. Compared to control animals, which required 2 to 6 challenges (median=3 weeks) for infection, a single bNAb infusi
