1Regarding HIV infection all of the following are true except
- AIt is retrovirus that infects CD4 T cells, dendritic cells and macrophages and binds to gp120
- Bgp 120 changes conformation and binds co-receptors CCR5 and CXCR4
- CReverse transcriptase copies viral ssRNA genomes into ds cDNA
- DReplication of HIV occurs in activated T and B cells
- EA genetic deficiency of the co-receptor CCR5 confers resistance to HIV infection in vivo
2All of the following are seen in a typical course of HIV infection except
- AInfected CD4 cells die as a result of viral replication
- BThere is a latent viral reservoir in the lymphoid tissue
- Cgp 120 expressed on infected cell binds CD4 on uninfected cell and they fuse forming multinucleated giant cells in HIV infected brain
- DOpportunistic infections will begin to arise when CD4 T cell count goes below 400 cell/cubic mm
3You need 2 positive ELISA and a confirmatory positive Western Blot to confirm HIV positive status
- ATrue
- BFalse
4All of the following are true about HIV drugs except?
- ABlock CCR5 - will block fusion
- BBlock Reverse Transcriptase - Blocks integration
- CBlock maturation (gp 160 -> gp41)
- DHAART (Highly Active Anti-retroviral Therapy) = 1 NRTIs + a PI/NNRTI/II
