18. What Have We Learned from Δ32/Δ32 stem cell transplantation? -HIV infection is critically dependent on CCR5 -HIV persistence is critically dependent on CCR5 -The role of tissues not derived from bone marrow in persistence and infection is in question But… n=1!

19. What Have We Learned from the Elite Controllers? -Defined by the ability to spontaneously suppress plasma viremia -Occurs in less than 1% of HIV-infected individuals -Elevated CD4 cell counts, stable CD4 trajectories, and more favorable clinical outcomes -Overrepresentation of protective HLA alleles -Other mechanisms under active study -Immune Control of HIV infection is possible!

23. HIV Latency in CD4 + T cells - CD4 + T cell latency is established at the transcriptional level predominantly in central memory T cells -CD4 + T cell latency is rare (1/10 5 -10 6 resting CD4 T cells) -Sequence of latent proviruses does not evolve, suggesting no or low ongoing viral replication. -Patients successfully treated with HAART for longer than 10 years exhibit no appreciable decrease in the size of the latent reservoir.
