Adjuvant-specific innate gene signatures. RNA transcripts were measured from peripheral blood sampling prevaccination and 4 hours, 24 hours, 72 hours, and 14 days just after the initial immunization. (A) Heatmap displaying upregulation and downregulation of innate gene modules by adjuvant at 24 hours. (B) Representative plots displaying the expression amount of the IFN (type 1) module (leading panel) and Ag-presentation module (bottom panel). (C) Association networks depicting the amount of modules regulated in popular between every single adjuvant. Similarities in upregulation (red borders) and downregulation (blue borders) are shown; width of connecting lines indicates the number of modules in common, also shown numerically.

PolyIC:LC and the emulsion-based formulations elicited statistically greater mucosal IgG titers compared with alum alone, using the ANE/TLR4 formulation inducing the highest titer (supplemental Figure 3D). Mucosal IgA responses have been largely undetectable.Effect of adjuvants on Env T-cell responsesWe next assessed T helper cell 1 (TH1) and TH2 T-cell responses by enumerating IFN-g and IL-4 ELISpots, the canonical cytokines for such responses, respectively (supplemental Figure 4A). Animals28 NOVEMBER 2017 x VOLUME 1, NUMBERimmunized with Env alone or Env 1 alum had low to undetectable IFN-g or IL-4 responses. In contrast, alum/TLR7 or pIC:LC had a higher frequency of TH1/IFN-g responses ranging from ;one hundred to ;1000 ELISpots but low to undetectable TH2/IL-4 responses.Serum Albumin/ALB Protein Purity & Documentation Immunization with MF59, ANE formulations with TLR4 or 7, and ISCOMs resulted in mixed TH1/TH2 responses with comparable frequencies of IFN-gand IL-4 roducing cells.Klotho Protein MedChemExpress Analysis of responses by flow cytometry showed that Env-specific CD41 T cells producing IFN-g was highest in animals immunized with pIC:LC (;0.PMID:23892746 4 ) (supplemental Figure 4B).
