Role of USP16 in Aβ1–42-Induced Alzheimer's Disease: Targeting IFI16 to Alleviate the Inflammatory Response

Open access
Cui, Bo, Ding, Yan, Li, Cunjiang·2025·Discovery Medicine

Abstract

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by β-amyloid (Aβ) accumulation, neuroinflammation, and neuronal loss. Interferon gamma-inducible protein 16 (IFI16) regulates inflammatory processes in AD, while ubiquitin-specific peptidase 16 (USP16) has been shown to ameliorate memory deficits in AD models. This study aimed to elucidate the interplay between USP16 and IFI16 in AD pathogenesis. Methods: Differentially expressed genes associated with AD were identified using dataset GSE129296. Glial cells were exposed to β-amyloid peptide (Aβ)1–42 to establish an in vitro AD model, followed by indirect co-culture with neuronal cells. Neuronal viability and apoptosis were evaluated using the Cell Counting Kit-8 assay and flow cytometry, respectively. Levels of tumor necrosis factor (TNF)-α and interleukin (IL)-1β in model glial cells were quantified by Enzyme-linked immunosorbent assay (ELISA). A potential deubiquitylating enzyme of IFI16 was predicted using Ubibrowser and confirmed by co-immunoprecipitation, while the ubiquitination levels of IFI16 were assessed. The expression of USP16/IFI16 and toll-like receptor 4 (TLR4)/NLR family pyrin domain containing 3 (NLRP3) was determined by reverse transcription-quantitative PCR (RT-PCR) and western blotting. Results: IFI16 was markedly upregulated in AD. Silencing of IFI16 attenuated Aβ1–42-induced proinflammatory responses in glial cells, reduced neuronal apoptosis, and enhanced neuronal viability, accompanied by decreased inflammatory cytokine levels and downregulation of TLR4/NLRP3 expression. USP16, identified as the deubiquitylating enzyme of IFI16, was significantly elevated in Aβ1–42-stimulated glial cells, and its silencing reduced IFI16 expression. Furthermore, IFI16 overexpression reversed the effects of USP16 knockdown on cell survival, apoptosis, and inflammation. Conclusion: USP16 depletion alleviates inflammation and apoptosis in AD cellular models through modulation of IFI16, suggesting that USP16 may serve as a promising therapeutic target for AD.

TL;DR

This study identifies USP16 as a deubiquitylating enzyme of IFI16 and shows that USP16 depletion alleviates Aβ1–42-induced inflammation and neuronal apoptosis in cellular AD models. The effects appear mediated through IFI16 and the TLR4/NLRP3 signaling axis.

Key findings

  • IFI16 was markedly upregulated in AD according to dataset GSE129296; silencing IFI16 attenuated Aβ1–42-induced proinflammatory responses in glial cells, reduced neuronal apoptosis, and enhanced neuronal viability, with decreased TNF-α and IL-1β levels and downregulation of TLR4/NLRP3 (p < 0.05).
  • USP16 was identified as the deubiquitylating enzyme of IFI16, was significantly elevated in Aβ1–42-stimulated glial cells, and its silencing reduced IFI16 expression (p < 0.05).
  • Co-immunoprecipitation and in vitro deubiquitylation assays showed ectopically expressed USP16 interacted with IFI16, and USP16 silencing enhanced IFI16 ubiquitination.
  • IFI16 overexpression reversed the effects of USP16 knockdown on cell survival, apoptosis, and inflammation; USP16 silencing reduced TNF-α/IL-1β and TLR4/NLRP3 and reversed IFI16-induced neuronal damage (p < 0.05).

Methods

  • Differentially expressed genes associated with AD were identified using dataset GSE129296 via GEO2R; Ubibrowser was used to predict deubiquitylating enzymes targeting IFI16.
  • HMC3 glial cells were exposed to Aβ1–42 (5 µM for 24 h) to establish an in vitro AD model, then indirectly co-cultured with SH-SY5Y neuronal cells; HEK-293T cells were used for co-immunoprecipitation and in vitro deubiquitylation assays.
  • Neuronal viability and apoptosis were assessed by CCK-8 and flow cytometry; TNF-α and IL-1β by ELISA; USP16/IFI16 and TLR4/NLRP3 expression by RT-qPCR and western blotting. Statistics used mean ± standard deviation, independent samples t-test or one-way ANOVA with Tukey post-hoc, with p < 0.05 considered significant.

Limitations

  • Stated in the paper: the current study lacks in vivo validation to further validate the findings, which the authors say will be the focus of future investigations.
  • Evident from the text: the experimental evidence is based on in vitro cell models (HMC3, SH-SY5Y, HEK-293T) and bioinformatic prediction, with no in vivo or human tissue validation reported.

    “Based on previous studies [19], treatment with 5 µM Aβ1-42 for 24 h was performed for subsequent experiments.”
  • The paper relies on this without support.

    In vitro findings in cell lines can be extrapolated to AD pathophysiology in vivo.

    “suggesting that USP16 may serve as a promising therapeutic target for AD.”
  • The paper relies on this without support.

    The precise role and mechanisms of IFI16 in AD pathogenesis remain insufficiently elucidated.

    “Nevertheless, the precise role and mechanisms of IFI16 in AD pathogenesis remain insufficiently elucidated.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Dilution is said to increase Aβ1-42 concentration

    Major

    The preparation starts with a 5 μM peptide solution, then says dilution with PBS produces a 400 μM solution. Dilution alone cannot raise the concentration eightyfold.

  • Section heading assigns USP16 the opposite inflammatory role

    Minor

    The heading says USP16 antagonized IFI16-mediated inflammation, but the section reports that knocking down USP16 reduced inflammation and reversed the proinflammatory effects of IFI16 overexpression.

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 2026-11-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-09 (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.
