Senolytic drugs, dasatinib and quercetin, attenuate adipose tissue inflammation, and ameliorate metabolic function in old age
Open accessAbstract
Aging results in an elevated burden of senescent cells, senescence‐associated secretory phenotype (SASP), and tissue infiltration of immune cells contributing to chronic low‐grade inflammation and a host of age‐related diseases. Recent evidence suggests that the clearance of senescent cells alleviates chronic inflammation and its associated dysfunction and diseases. However, the effect of this intervention on metabolic function in old age remains poorly understood. Here, we demonstrate that dasatinib and quercetin (D&Q) have senolytic effects, reducing age‐related increase in senescence‐associated β‐galactosidase, expression of p16 and p21 gene and P16 protein in perigonadal white adipose tissue (pgWAT; all p ≤ 0.04). This treatment also suppressed age‐related increase in the expression of a subset of pro‐inflammatory SASP genes ( mcp1, tnf‐α, il‐1α, il‐1β, il‐6, cxcl2, and cxcl10 ), crown‐like structures, abundance of T cells and macrophages in pgWAT (all p ≤ 0.04). In the liver and skeletal muscle, we did not find a robust effect of D&Q on senescence and inflammatory SASP markers. Although we did not observe an age‐related difference in glucose tolerance, D&Q treatment improved fasting blood glucose ( p = 0.001) and glucose tolerance ( p = 0.007) in old mice that was concomitant with lower hepatic gluconeogenesis. Additionally, D&Q improved insulin‐stimulated suppression of plasma NEFAs ( p = 0.01), reduced fed and fasted plasma triglycerides (both p ≤ 0.04), and improved systemic lipid tolerance ( p = 0.006). Collectively, results from this study suggest that D&Q attenuates adipose tissue inflammation and improves systemic metabolic function in old age. These findings have implications for the development of therapeutic agents to combat metabolic dysfunction and diseases in old age.

TL;DR
In old male C57BL/6 mice, intermittent dasatinib plus quercetin (D&Q) reduced senescence and inflammatory markers in perigonadal white adipose tissue and improved systemic glucose and lipid metabolism. Improved glucose tolerance was linked to suppressed hepatic gluconeogenesis and was independent of pancreatic beta-cell function or peripheral insulin sensitivity.
Key findings
- In pgWAT, D&Q reduced age-related SA β-gal+ cells, crown-like structures, p16 and p21 gene expression, and P16 protein (all p ≤ 0.04), and lowered SASP genes mcp1, tnf-α, il-1α, il-1β, il-6, cxcl2, and cxcl10 (all p ≤ 0.03). It also reduced T cells and total, M1, and M2 macrophages in pgWAT (all p ≤ 0.04 or p ≤ 0.01).
- D&Q reduced fasting blood glucose (p = 0.002) and improved glucose tolerance (interaction p ≤ 0.0001; AUC p = 0.0004) in old mice. Pyruvate tolerance improved (interaction p = 0.012; treatment p = 0.004), with lower hepatic gluconeogenic gene expression (pck1, pck2, fbp2, g6pc; all p ≤ 0.04) and lower p-CREB/CREB ratio (p = 0.047).
- D&Q improved insulin-stimulated suppression of plasma NEFAs (p = 0.009), reduced fed and fasted plasma triglycerides (both p ≤ 0.04), and improved lipid tolerance (interaction p = 0.014; treatment p = 0.006; AUC p = 0.006), without altering plasma cholesterol, LDL/VLDL, or HDL (p ≥ 0.62).
- Effects were tissue-specific: liver p16 gene expression was reduced (p ≤ 0.003) but P16 protein was not altered by D&Q (p = 0.83); liver mcp1 was reduced (p = 0.04) but tnf-α and il-1β were not (p ≥ 0.31); gastrocnemius senescence/inflammatory markers were unchanged (p ≥ 0.19). Liver collagen deposition was reduced by D&Q (p = 0.007).
Methods
- Male C57BL/6 mice: young controls and 21-month-old old mice received D&Q (dasatinib 5 mg/kg, quercetin 50 mg/kg) by oral gavage on 3 consecutive days every 2 weeks for 3 months, or vehicle (10% polyethylene glycol 4000). Group sizes were N = 5–8/group for many assays; Table 1 reports N = 8 young control, 15 old control, 17 old D&Q.
- Outcomes included glucose, insulin, pyruvate, and intralipid tolerance tests; glucose-stimulated insulin; insulin-stimulated NEFA suppression; plasma triglycerides and cholesterols; flow cytometry for pgWAT T cells and macrophages; qPCR and western blots for senescence, SASP, gluconeogenic, and insulin-signaling markers; and SA β-gal, H&E, and picrosirius red histology.
- Statistics used one-way or two-way ANOVA, repeated-measures ANOVA, and Student’s t tests, with significance set at p < 0.05.
Limitations
- Stated: young and old control mice did not differ in fasting glucose, glucose tolerance, pyruvate tolerance, or lipid tolerance; the C57BL/6 model may not recapitulate all human metabolic dysfunction; human aging includes diet, lifestyle, and microbiota confounders absent in mice; mouse cholesterol metabolism differs from humans; mechanisms and the relative contribution of senescence in individual tissues/cell types require further investigation.
- Evident: only male mice were studied, so sex differences are not addressed. Several assays used small group sizes (N = 5–8/group), and D&Q effects were not robust in liver or skeletal muscle, limiting conclusions about those tissues.

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.
