The histone deacetylase HDAC11 regulates the expression of interleukin 10 and immune tolerance

Open access

Abstract

Antigen-presenting cells (APCs) induce T cell activation as well as T cell tolerance. The molecular basis of the regulation of this critical 'decision' is not well understood. Here we show that HDAC11, a member of the HDAC histone deacetylase family with no prior defined physiological function, negatively regulated expression of the gene encoding interleukin 10 (IL-10) in APCs. Overexpression of HDAC11 inhibited IL-10 expression and induced inflammatory APCs that were able to prime naive T cells and restore the responsiveness of tolerant CD4+ T cells. Conversely, disruption of HDAC11 in APCs led to upregulation of expression of the gene encoding IL-10 and impairment of antigen-specific T cell responses. Thus, HDAC11 represents a molecular target that influences immune activation versus immune tolerance, a critical 'decision' with substantial implications in autoimmunity, transplantation and cancer immunotherapy.

Written from the paper’s full text.

TL;DR

HDAC11 is identified as a negative transcriptional regulator of IL-10 in antigen-presenting cells, acting mainly at the distal Il10 promoter and requiring its deacetylase activity. Manipulating HDAC11 changes APC inflammatory status and alters priming versus tolerance of antigen-specific CD4+ T cells.

Key findings

  • Overexpression of HDAC11 inhibited LPS-induced IL-10 mRNA in RAW264.7 macrophages, primary mouse macrophages, human dendritic cells and THP-1 cells, while increasing IL-12 mRNA in several of these APC populations; HDAC11 knockdown or stable HDAC11-deficient RAW264.7 clones showed the opposite IL-10 effect.
  • HDAC11 acted at the distal Il10 promoter: HDAC11 was detected mainly in the distal region (positions −807 to −1653), and adding this distal Il10 segment to the short Il12 promoter (−1 to −756) conferred strong HDAC11-mediated inhibition. HDAC11 was not detected on the Il12 promoter.
  • Intact enzymatic activity was required: wild-type HDAC11 inhibited IL-10 mRNA, whereas an HDAC11 mutant lacking the deacetyltransferase domain failed to inhibit and instead increased IL-10 mRNA, suggesting dominant-negative action.
  • Functionally, HDAC11-overexpressing macrophages expressed more CD86 and CD40, produced less IL-10 and more IL-12, activated naive hemagglutinin-specific CD4+ T cells more strongly, and restored IL-2 and IFN-γ production in tolerant CD4+ T cells; APCs lacking HDAC11 impaired antigen-specific CD4+ T cell responses.

Methods

  • Used mouse RAW264.7 macrophages, primary mouse peritoneal macrophages, human THP-1 monocytic cells and human monocyte-derived dendritic cells; BALB/c mice and influenza hemagglutinin TCR-transgenic mice were used for T cell studies.
  • Overexpressed Flag- and GFP-tagged HDAC4–HDAC11 via adenovirus, knocked down HDAC11 with lentiviral shRNA, and used Il10, Il12 and chimeric Il10-Il12 luciferase reporter assays, ChIP, real-time RT-PCR, immunoblot, ELISA and flow cytometry.
  • mRNA was normalized to GAPDH with the Pfaffl method; assays were done in triplicate and repeated at least three times; T cell cytokine production was expressed as pg/ml per 1 × 10² clonotype-positive CD4+ T cells.

Limitations

  • The paper does not state limitations.
  • Evident from the text: most mechanistic work was done in transformed cell lines and in vitro primary APCs, with human data limited largely to mRNA measurements in dendritic cells and THP-1 cells.
  • Evident from the text: HDAC11 was manipulated in APCs in vitro, while the tolerance model involved in vivo peptide-induced T cell tolerance; the proposed distal-to-proximal chromatin “scaffolding” mechanism is presented as plausible rather than directly demonstrated.

    IL-10 negatively regulates IL-12 expression.

    “Given that IL-10 negatively regulates IL-12 expression, the presence of IL-10 in our experimental system might have masked a potential direct regulatory effect of HDAC11 on Il12 expression.”
  • The paper relies on this without support.

    The in vitro antigen-presentation assays with PEMs and RAW264.7 cells reflect the functional response of antigen-specific CD4+ T cells in vivo.

    “The additional demonstration that genetic manipulation of HDAC11 influenced the inflammatory status of APCs and their ability to determine the functional response of antigen-specific CD4+ T cells indicates that this molecule is a likely target for influencing APC-mediated immune activation versus immune tolerance.”
  • The paper relies on this without support.

    The molecules involved and the sequence of events mediating chromatin modifications of the Il10 promoter are not fully understood.

    “However, the molecules involved and the sequence of events mediating these chromatin modifications are not fully understood.”

    Little is known about the function of HDAC11 in normal and/or transformed cells.

    “Although there is much information about its structure, enzymatic activity and tissue distribution23,30, little is known about the function of this HDAC in normal and/or transformed cells.”

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.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
