1 Rapporteur Report – Track A Basic and Translational Sciences
Mathias Lichterfeld, M. D., Ph. D. Associate Professor of Medicine Brigham and Women’s Hospital Harvard Medical School no relevant conflicts of interest or other disclosures

2 The number of identical HIV-DNA sequence expansions increases over time in peripheral blood
Lee/Palmer et al, Abstract MOAA0105

3 Defective proviruses can encode for HIV-1 protein
Imamichi/Lane et al, Abstract MOPDA0102

4 HIV-specific CD8+ T cells in early treated subjects are more functionally competent
Untreated IFN-gamma CD8 Tetramer Nkosi/Ndhlovu et al, Abstract TUAA0101

5 hetIL-15 Treatment Increases SIV-specific T Cells
Within the Lymph Nodes CD8 CM9 Tetramer+ Untreated hetIL-15 0.3 2.5 CD3+ T lymphocytes in LN Tetramer+ Granzyme B Ki67 Expansion Cytotoxic Potential Valentin/Pavlakis et al, Abstract TUPDA0103

6 hetIL-15 Treatment Increases SIV-specific T Cells
Within the Lymph Nodes germinal center Pre-ALT803 Post-ALT803 Webb/Sacha et al, Abstract TUPDA0104

7 Plasma viremia in SIV-infected NHP
after treatment with ART and a4/b7 antibodies or control Fauci et al, Presentation MOSS0102

8 Viral control following a4b7 antibody infusion is
Likely mediated by cellular immune responses Fauci et al, Presentation MOSS0102

9 Prolonged HIV-1 control after perinatal infection “The South African Baby”
HIV-1 DNA detectable at 32 days of life Initiated AZT/3TC/LPV/r at 8.5 weeks of life Interrupted ART after 40 weeks 3-monthly f/u Undetectable VL after 8.75 years off ART on stored and current specimens No protective HLA class I alleles Weak HIV-specific T/B cell responses 5 HIV DNA copies/ million CD4 T cells VOA negative x2 Violari/Tiemessen et al, Abstract TUPDB0106LB

10 Delayed viral rebound after treatment during hyperacute
HIV-1 infection Participant A: Underwent ATI after 34 months of ART Latent reservoir size ≈200 cells prior to ATI ≈1% of individuals with a similar HIV burden may achieve lifelong ART-free remission Henrich/Deeks et al, Abstract TUPDB0103

11 Effects of therapeutic vaccination in ART-treated
HIV patients on viral rebound kinetics Fauci et al, Presentation MOSS0102

12 Therapeutic vaccination has no effect on viral rebound
kinetics or viral reservoir markers Fauci et al, Presentation MOSS0102

13 Viral reservoir biomarkers represent predictors of
viral rebound kinetics Fauci et al, Presentation MOSS0102

14 Many thanks! Nancie Archin, PhD Univ of North Carolina, Chapel Hill
