Trimethylamine‐N‐Oxide Induces Vascular Inflammation by Activating the NLRP3 Inflammasome Through the SIRT3‐SOD2‐mtROS Signaling Pathway
Open accessAbstract
Background: Trimethylamine‐N‐oxide ( TMAO ) has recently been identified as a novel and independent risk factor for promoting atherosclerosis through inducing vascular inflammation. However, the exact mechanism is currently unclear. Studies have established a central role of nucleotide‐binding oligomerization domain–like receptor family pyrin domain–containing 3 ( NLRP 3) inflammasome in the pathogenesis of vascular inflammation. Here, we examined the potential role of the NLRP 3 inflammasome in TMAO ‐induced vascular inflammation in vitro and in vivo and the underlying mechanisms. Methods and Results: Experiments using liquid chromatography‐tandem mass spectrometry, Western blot, and fluorescent probes showed that TMAO ‐induced inflammation in human umbilical vein endothelial cells ( HUVEC s) and aortas from ApoE −/− mice. Moreover, TMAO promoted NLRP 3 and activated caspase‐1 p20 expression and caspase‐1 activity in vitro and in vivo. Notably, a caspase‐1 inhibitor ( YVAD ), an NLRP 3 inhibitor ( MCC 950), as well as NLRP 3 short interfering RNA attenuated TMAO ‐induced activation of the NLRP 3 inflammasome, subsequently leading to suppression of inflammation in HUVEC s. TMAO additionally stimulated reactive oxygen species ( ROS ) generation, in particular, mitochondrial ROS , while inhibiting manganese superoxide dismutase 2 (SOD2) activation and sirtuin 3 ( SIRT 3) expression in HUVEC s and aortas from ApoE −/− mice. TMAO ‐induced endothelial NLRP 3 inflammasome activation was ameliorated by the mitochondrial ROS scavenger Mito‐ TEMPO , or SIRT 3 overexpression in HUVEC s. Conversely, TMAO failed to further inhibit SOD2 and activate the NLRP 3 inflammasome or induce inflammation in SIRT 3 short interfering RNA –treated HUVEC s and aortas from SIRT 3 −/− mice. Conclusions: TMAO promoted vascular inflammation by activating the NLRP 3 inflammasome, and the NLRP 3 inflammasome activation in part was mediated through inhibition of the SIRT 3‐ SOD 2–mitochondrial ROS signaling pathway.

TL;DR
TMAO promotes vascular inflammation by activating the NLRP3 inflammasome, mediated in part through inhibition of the SIRT3-SOD2-mtROS signaling pathway. In HUVECs and mouse aortas, TMAO increased NLRP3/caspase-1 p20 and inflammatory markers, while SIRT3 overexpression or mtROS scavenging attenuated these effects.
Key findings
- TMAO (600 μmol/L for 24 hours) increased IL-1β, ICAM-1, and MMP-9 expression and monocyte adhesion in HUVECs without significantly affecting cell viability; TMAO also promoted NLRP3 and caspase-1 p20 expression and caspase-1 activity in concentration- and time-dependent manners.
- NLRP3 inhibition with MCC950 (10 μmol/L), caspase-1 inhibition with YVAD (10 μmol/L), or NLRP3 siRNA attenuated TMAO-induced NLRP3/caspase-1 p20 and inflammatory protein expression, as well as monocyte adhesion.
- TMAO increased total ROS and mitochondrial ROS (mtROS); the mtROS scavenger Mito-TEMPO (TEMPO, 50 μmol/L) inhibited TMAO-induced NLRP3 inflammasome activation and inflammation. TMAO suppressed SOD2 activity and SIRT3 expression and increased SOD2 acetylation; SIRT3 siRNA mimicked TMAO effects, whereas SIRT3 overexpression diminished them.
- In vivo, 1% choline for 4 months in ApoE−/− mice increased plasma TMAO, atherosclerotic lesion areas in whole aorta and aortic root, and aortic NLRP3, caspase-1 p20, caspase-1 activity, IL-1β, ICAM-1, and MMP-9; SIRT3−/− mice showed similar inflammasome activation even on chow diet.
Methods
- In vitro: HUVECs were treated with TMAO (0, 150, 300, 600, 900 μmol/L) for 24 hours or 600 μmol/L for 0, 4, 12, and 24 hours; interventions included YVAD (10 μmol/L), MCC950 (10 μmol/L), TEMPO (50 μmol/L), NLRP3 siRNA, SIRT3 siRNA, and SIRT3 overexpression plasmid. Assays included Western blot, caspase-1 activity, SOD2 activity, DCFH-DA/MitoSOX ROS detection, and monocyte adhesion.
- In vivo: 8-week-old female 129/SvJ wild-type, ApoE−/−, and SIRT3−/− mice were fed standard chow or 1% choline-supplemented chow for 4 months; n=10 per group. Analyses included plasma TMAO by liquid chromatography-tandem mass spectrometry, aortic Western blot, caspase-1 and SOD2 activity, ultrasound of aortic sinus, and Oil-red O lesion quantification.
- Statistics: data presented as means±SE of 3 experiments; t test and 1-way ANOVA with Tukey-Kramer post hoc test, significance at P<0.05.
Limitations
- Stated by the paper: the 600 μmol/L TMAO concentration used for in vitro time-course and mechanism studies was higher than that in humans; the exact role of NF-κB in TMAO-induced NLRP3 inflammasome activation needs further studies.
- Evident from the text: in vivo experiments used dietary choline as a TMAO precursor rather than direct TMAO administration, and only female mice were studied; no human intervention data are presented.

The Results section calls ROS generation one mechanism of NLRP3 activation and says mitochondrial ROS seems particularly critical. But the Introduction says the mechanisms remain unclear and lists several possibilities; the paper does not establish ROS generation as the most well-characterized mechanism. (LLM, conf=0.84)

The authors state this as an assumption.
Lower concentrations of TMAO would have some impact, although it may be hard to detect experimentally.
“AS is a chronic disease that develops over many years, and one can assume that lower concentrations of TMAO would have some impact, although it may be hard to detect experimentally.”
The paper relies on this without support.
Mitochondria are the major source of cellular ROS.
“Importantly, mitochondria are the major source of cellular ROS.”
The paper relies on this without support.
Blood levels of TMAO are causatively linked to AS risk.
“Given that blood levels of TMAO are causatively linked to AS risk, the next obvious question is the mechanism by which circulating TMAO promotes AS, which is under active investigation.”

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 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
