Abstract

Key Points: Crosspriming of AAV capsid-specific CD8+ T cells requires cooperation between distinct subsets of DCs. Innate immune sensing of the viral DNA genome induces cross-presentation of viral capsid in trans.

  • The AAV vector genome triggers TLR9, a receptor that detects foreign DNA.

    “the genome of the vector activates Toll-like receptor 9 (TLR9), a pattern recognition receptor that senses foreign DNA”
  • pDCs are critical for the early TLR9/MyD88-dependent innate response to AAV and orchestrate anti-capsid CD8+ T cell responses by activating conventional DCs to cross-present capsid antigen.

    “Plasmacytoid dendritic cells (pDCs) are critical for mounting a TLR9/MyD88-dependent early innate immune response to AAV vectors (15) and they subsequently orchestrate anti-capsid CD8+ T cell responses in vivo by activating conventional DCs to cross-present capsid antigen (18).”
  • The TLR9/MyD88 pathway is vital for mounting a CD8+ T-cell response against the AAV capsid and also liver and muscle-directed transgenes.

    “Furthermore, the TLR9/MyD88 pathway is not only vital for mounting a CD8+ T-cell response against the AAV capsid but also liver and muscle-directed transgenes [28, 34, 35, 41].”
  • Adaptive anti-capsid humoral and cytotoxic immune responses have been shown to be restricted in vivo by inhibiting innate immune activation pathways.

    “Adaptive anti-capsid humoral [27] and cytotoxic [28, 29] immune responses have been shown to be restricted in vivo by inhibiting innate immune activation pathways.”
  • Cooperation between plasmacytoid dendritic cells, conventional dendritic cells, and CD4+ T cells results in cross-presentation of AAV particles on MHC I, and subsequently activation of CD8+ T cells.

    “Studies suggest that cooperation between plasmacytoid DCs, conventional DCs, and CD4+ T cells results in cross-presentation of AAV particles on MHC I, and, subsequently, activation of CD8+ T cells [28, 29].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
