Abstract
Current HIV vaccines designed to stimulate CD8+ T cells have failed to induce immunologic control upon infection. Functions of vaccine-induced HIV-specific CD8+ T cells were investigated here in detail. HIV-specific CD8+ T-cell cytotoxic capacity was extremely low and was not a consequence of low frequency nor lack of accumulation of functional perforin (PRF) or granzyme B (GrB). Low cytotoxic capacity was attributable to impaired degranulation in response to the low levels of antigen present on HIV-infected CD4+ T cells. The T cell receptor (TCR) repertoire induced by these vaccines was polyclonal and transduction of these TCRs conferred the same reduced functions. These results define a mechanism accounting for the poor antiviral activity induced by these vaccines and suggest that an effective CD8+ T-cell response may require more intensive antigenic stimulation.

Description of the data and file structure
HIV-specific CD8+ T cell responses in HIV vaccine recipients are compared with those of chronically infected long-term nonprogressors / elite controllers (LTNP/EC) and progressors specifically as they relate to the response to HIV-infected autologous primary CD4+ T cell targets. LTNP/ECs represent a rare population of people living with HIV who maintain durable control over HIV replication without antiretroviral therapy. A variety of experimental assays employing subject derived peripheral blood mononuclear cells (PBMCs) were used in these investigations. Relative to chronically infected patients, we found that the CD8+ T cells induced by HIV vaccines exhibited lower cytotoxic capacity due to impaired degranulation and perforin polarization to the immunologic synapse. This was associated with reduced functional avidity and a polyclonal T-cell receptor (TCR) repertoire. Vaccinee-derived TCRs transduced into primary PBMCs had the same reduced functions, localizing the cause of low avidity to the antigen receptor.

File: EC_Sequences_VB_Summary.fas.txt
Description: "EC Sequences VB Summary" contains the full TCR beta and alpha chain, Variable region DNA sequences derived from the sorted immunodominant HLA class I/HIV Gag tetramer+ CD8+ T cells of seven LTNP/EC. The HIV tetramers used in these experiments include: A02-SLYNTVATL (A2-SL9), A0301-RLRPGGKKK (A3-RK9), B0801-EIYKRWII (B8-EI8), B2705-KRWIILGLNK (B27-KK10), B5701-KAFSPEVIPMF (B57-KF11), and B5701-QASQEVKNW (B57-QW9). Identifiers preceding nucleotide sequences include LTNP/EC subject number (e.g., EC01 refers to sequences derived from LTNP/EC subject 1), abbreviated peptide name corresponding to the epitope specificity recognized by the TCR (e.g., KK10 refers to the B27-KK10 specificity), clonotype number, and BV or AV to distinguish beta from alpha chain sequences, respectively.
File: Fig1AB_FigS4AB.csv
Description: "Fig1AB_FigS4AB" contains CD8+ T cell responses pre-HIV infection (Pre, n=34) and post-HIV infection (Post, n=14) in Adenovirus serotype 5 (Ad5) HIV vaccinees from the Step study compared with LTNP/EC (LTNP) and progressors (Prog). The 14 vaccinees, from whom postinfection PBMC samples were available, were divided into two subgroups based on either low (Low VL, <10,000 copies/ml, n=6) or high (High VL, >10,000 copies/ml, n=8) set point HIV-1 RNA levels (Log Viral Load or VL). A confocal microscopy bioimaging platform, called BD Pathway, was used to measure the ability of multi-day restimulated CD8+ T cells to eliminate HIV-infected CD4+ T cell targets (infected CD4 elimination, ICE) after a 40-minute incubation. Frequencies of CD107a+ and/or IFN-gamma+ CD8+ T cells were also quantified with cells from the same subjects by flow cytometry, expressed as percentages of “CD107 and/or IFN” positive cells. Background responses to uninfected CD4+ T cell targets were subtracted. Post-infection set point HIV-1 RNA levels and experimental results for the 14 “high VL” and “low VL” vaccinees are summarized in columns J-O. Results were compared among the groups by the Wilcoxon two-sample test.

- PI+ Tinf: percentages of PI+ live, infected CD4+ T cell targets
- GrB ELISA Diff: GrB extracellular concentration measured by ELISA
- GrB AUC: GrB substrate concentration measured by a microplate reader as the net area under the curve (AUC) changes in fluorescence of a fluorogenic GrB substrate in cell free supernatants
File: Fig2CF.csv
Description: "Fig2CF" contains ELISA measurements of PRF and GrB extracellular concentrations in response to uninfected (Tun) or infected (Tinf) CD4+ T cell targets and the differences of Tinf-Tun for LTNP/EC (LTNP), Prog, and HVTN 071 vaccinees (071). Rows 29-42 show PRF and GrB extracellular activities in the same groups, measured by flow cytometry as percentages and MFI of propidium iodide+ live CD4+ T cell targets (PI+ Tinf) or by a microplate reader as the net area under the curve (AUC) changes in fluorescence of a fluorogenic GrB substrate in cell free supernatants, respectively. Results were compared among the groups by the Wilcoxon two-sample test. For cells with N/A, these reflect conditions with cells from two LTNP/ECs where results for GrB ELISA with infected targets were uninterpretable (and could not be repeated) and thus the difference between the GrB measured with uninfected targets compared to infected targets could not be calculated.

Description: "Fig3AC" contains data for each subject on HLA class I A and B genotype (columns B and C), HLA class I/HIV tetramers used to stain expanded CD8+ T cells (column D), the numbers of tetramers used (column E), the expression of various markers on the HIV tetramer+ CD8+ T cells after stimulation with HIV-infected autologous CD4+ T cell targets (columns F through M), and cytotoxic responses expressed as infected CD4 elimination (ICE) when sufficient PBMCs were available from LTNP/EC, Progressors, and vaccinees in the HVTN 071, VRC_006, VRC_008 and HVTN 087 trials. VRC_006 refers to healthy subjects who received one dose of the VRC-replication-defective Ad5/HIV vaccine administered as a single intramuscular injection whereas VRC_008 refers to a boost after priming with three multi-antigen DNA vaccinations. Vaccinees in HVTN 087 were primed with three multiantigen DNA vaccinations (ProfectusVax) plus high-dose (1500 μg) Interleukin-12 before boosting with a live, attenuated vesicular stomatitis virus expressing HIV-1 Gag (VSV-Gag) Details of abbreviated names of the HIV tetramers (column D) are included in table S4. Responses to uninfected CD4+ T cell targets after 6-hour restimulation are subtracted from responses to infected CD4+ T cell targets (net results in columns H and I). Tetramer+ GrB delta (column L) is calculated by subtracting GrB MFI of tetramer+ cells in response to uninfected CD4+ T cell targets (column J) from GrB MFI of tetramer+ cells in response to infected CD4+ T cell targets (column K). Percent tetramer+ GrB delta MFI (column M) is derived from dividing tetramer+ GrB delta MFI (column L) by GrB MFI of tetramer+ cells in response to uninfected CD4+ T cell targets (column J). Group comparisons were determined by the Wilcoxon two-sample test and correlations were measured by the Spearman rank method. N/A data in the LTNP/EC and progressor groups indicates subjects where certain markers were not measured. N/A among the vaccinees reflects samples where low small cell numbers precluded measurement of ICE.

File: Fig4AC_FigS11B.csv
Description: contains functional avidity data on CD107a expression measured by flow cytometry of virus tetramer/multimer-labelled (column B) CD8+ T cells of LTNP/EC, progressors, Ad5/HIV vaccinees and individuals with “other specificities”, including controlled cytomegalovirus (CMV) infection, convalesced influenza virus (Flu) or respiratory syncytial virus (RSV) infections and SARS-CoV-2 mRNA vaccine recipients (SARS-CoV-2 Vx) in response to 10-fold serial dilutions of viral peptide (column B), ranging from 10e-9 M (-9) to 10e-5 M (-5) (columns D through H). Details of abbreviated names of the viral multimers (column B) are included in table S4. Cells from some patients were used in experiments in which CD8+ T cell responses to HIV-infected CD4+ T cell targets (Inf T, column I) were plotted on the peptide-response curves (derived from the same CD8 effectors) to interpolate the peptide concentration that would yield the same degranulation response from stimulation with infected targets. Individuals where this was not done have N/A. Half-maximal effective concentrations (EC50) inducing CD107a expression in HIV tetramer+ CD8+ T cells from LTNP/EC, progressors and Ad5/HIV vaccinees were estimated by a non-linear fit model (column J). One LTNP/EC had measurements done with two HIV viral multimers and thus the half-maximal concentration was only reported for one multimer (and the other shows N/A). The half-maximal concentration was not calculated for non-HIV specificities and instead curve analysis was performed (corresponding cells show N/A). Responses were compared across all dilutions by the GEE method and pairwise comparisons were analyzed by the Wilcoxon two-sample test.

File: FigS7CD.csv
Description: "FigS7CD" contains data, related to the results presented in “FigS7A” and "FigS7B", and includes frequencies of CD8+ T cell-derived signaling phosphoproteins (p-IkBa, p-MEK1-2, p-NFkB p65, p-STAT1, p-STAT3, and p-STAT5; rows 2 through 7) measured from the IsoCode Signaling Chips and the frequencies of individual cells expressing PRF, alone or in combination with up to 31 other immune-related proteins, out of the total sample, which were detected from the IsoCode Secretome Chips (“Secreted PRF”, row 9) or the IsoCode Signaling Chips (“Secreted and Intracellular PRF”, row 10). Comparisons were made using the Wilcoxon two-sample test.
File: FigS9.csv
Description: "FigS9" contains data on CD8+ T cell cytotoxic responses to HIV-infected autologous CD4+ T cell targets, expressed as infected CD4 elimination (ICE), that was measured by flow cytometry for LTNP/EC, progressors, and vaccinees with sufficient numbers of PBMCs from HVTN 071 (071), VRC_006/008, and HVTN 087 (087). Comparisons were made using the Wilcoxon two-sample test.
Variables
- LTNP/EC: long-term nonprogressor
- Progressors: progressor
- 071: 12 Ad5/HIV vaccinees who had undergone leukaphereses as part of HVTN 071
- VRC_006/008: VRC_006 refers to healthy subjects who received one dose of the VRC-replication-defective Ad5/HIV vaccine administered as a single intramuscular injection whereas VRC_008 refers to a boost after priming with three multi-antigen DNA vaccinations
- 087: Vaccinees in HVTN 087 were primed with three multiantigen DNA vaccinations (ProfectusVax) plus high-dose (1500 μg) Interleukin-12 before boosting with a live, attenuated vesicular stomatitis virus expressing HIV-1 Gag (VSV-Gag)
File: FigS7B.csv
Description: "FigS7B", which is related to “FigS7A”, contains thresholded (signal intensity normalized relative to that of cell-free microchambers), log transformed secretome data for the same patients shown in FigS7A that was then converted into percent frequencies of multifunctional CD8+ T cell subsets, i.e., the percentages of cells significantly secreting a specific profile of immune-based proteins, for the Granzyme B (column E), MIP-1B (column F), Perforin (column G) and RANTES (column H) immune protein profiles shown on the heatmap in fig. S7B. IsoSpeak software was used to analyze and compare single cell functional phenotypes.
Variables
- Donor Group: Sample categorized as either LTNP/EC or Ad5/HIV vaccinees
- External Donor: Identifies the specific sample used under each donor group LTNP/EC (LTNP/EC 1, LTNP/EC 3) and vaccinees (HVTN 071-70 and Step 9734)
- Cell Subset: secretome analysis only performed on proteins secreted from CD8+ T cells
- Granzyme B: granzyme B
- MIP-1b: macrophage inflammatory protein-1beta

File: FigS12.csv
Description: "FigS12" contains mass spectrometry analysis of PBMC targets pulsed with 10-fold serial dilutions, ranging from 1 nanomolar to 10 micromolar, of the EIYKRWII (B8-EI8) or the FLKEKGGL (B8-FL8) “light”/“endogenous” peptides and then spiked with the corresponding “heavy” peptides, which contained one isotope-labeled amino acid. Area-under-the-curve results are provided. Two technical replicates were performed for each condition.
Variables
- Peptide: short chain of amino acids used to pulsed peripheral blood mononuclear cells at various concentrations
- TYPE: either light/endogenous or heavy. The heavy peptides contained one isotope-labeled amino acid
- 1nM: one nano molar peptide concentration
- 10nM: ten nanomolar peptide concentration
- 100nM: one hundred nano molar peptide concentration
- 1uM: one micro molar peptide concentration
- 10uM: ten micromolar peptide concentration
File: FigS14A.csv
Description: "FigS14A" contains flow cytometry-measured expression of the activation/costimulatory receptors CD2, CD11a, CD18, and CD8b on Gag peptide-expanded total CD4+ T cells (columns C through F), total CD8+ T cells (columns G through J), and HIV tetramer+ CD8+ T cells (columns K through N) of LTNP/EC (rows 3 through 10) and Ad5/HIV vaccinees (rows 13 through 21). The four HLA class I/HIV tetramers used in these experiments (column B) were: B2705-KRWIILGLNK (B27-KK10), B5701-KAFSPEVIPMF (B57-KF11), A0301-RLRPGGKKK (A3-RK9), and B0801-EIYKRWII (B8-EI8). Data was not available in cells marked with an “X” due to very low HIV tetramer+ CD8+ T cell frequencies. Comparisons were made using the Wilcoxon two-sample test.
Variables
- CD4: Gag peptide-expanded total CD4+ T cells
- CD8: Gag peptide-expanded total CD8+ T cells
- CD8-HIV Tetramer: Gag peptide-expanded HIV-tetramer CD8+ T cells
