Carotid stenosis is also a common comorbidity in older individuals and often predicts subsequent AIS. However, no age-specific therapy is currently available to protect the aging brain from aggravated ischemic injury. Here, we investigated whether a senolytic approach could improve cerebrovascular status and reduce ischemic brain injury in a comorbid aging model of AIS. Unilateral common carotid artery occlusion was induced in young and aged rats and served as a diagnostic trigger for chronic senolytic therapy with dasatinib plus quercetin (D+Q). Two weeks later, the distal middle cerebral artery was occluded for 60 min. Compared with vehicle-treated animals, infarct size was measured, spreading depolarizations (SDs) were recorded electrophysiologically, cerebral blood flow (CBF) dynamics were monitored by laser speckle contrast imaging, and cerebrovascular senescent cell burden was assessed by immunocytochemistry. Cerebral angiogenesis, central and systemic inflammatory markers, and metabolic status were evaluated using protein arrays and blood glucose measurements. Aged rats developed larger infarcts than young controls, and this age-related increase was attenuated by D+Q treatment. D+Q reduced the higher frequency of SDs observed in the aged ischemic brain. Increased cerebrovascular senescence in aged animals was diminished by D+Q, accompanied by enhanced angiogenesis, although CBF responses to SDs and reperfusion were unchanged. In addition, D+Q modulated central and systemic inflammatory profiles and counteracted age-related metabolic impairment. Senolytic D+Q therapy administered after carotid artery occlusion confers multifaceted protection against subsequent AIS in the aged brain. By targeting fundamental aging mechanisms that exacerbate brain vulnerability to AIS, D+Q enhanced the resilience of the aging neurovascular niche.

These predictions converge on a formal revision in which sex is not a confounder to be controlled for, but a core biological moderator that may moderate modality-specific neuroprotection.

This review examines whether that framework holds when the host is old. Rather than surveying cancer immunology and aging comprehensively, it focuses on one question: whether the four host capacities the standard account of immunoediting and checkpoint blockade assumes still hold in the aged host. These are a naive T-cell repertoire wide enough to generate tumor-specific clones, a stromal environment that does not suppress priming, functional natural killer [NK] cell surveillance, and an immune baseline free of chronic inflammation. Aging alters all four, but not uniformly. Thymic involution and NK cell decline result in the immune system operating at reduced capacity, representing a shift in severity rather than a fundamental change in mechanism. The NK cell axis is disproportionately significant, as no approved therapies currently restore its function. In contrast, aged stromal senescence and inflammaging represent qualitative changes: the tissue environment becomes suppressive prior to tumor development, rather than as a consequence of tumor presence. The clinical evidence neither confirms nor refutes this interpretation. Older and younger patients gain similar benefit from checkpoint blockade, which is easily read as age being immunologically irrelevant. We argue instead that chronological age bundles aging changes acting on response in opposite directions. What predicts response is more accurately captured by immunological age than by chronological age. This reframing has a clear translational consequence. Therapeutic approaches should not only target the release of suppressed immune responses but also address the correction of the aged microenvironment. This hypothesis is currently being evaluated by senolytic strategies, which have been tested in an initial clinical trial and are supported by converging preclinical evidence.</p>","PeriodicalId":7434,"journal":{"name":"Aging and Disease","volume":" ","pages":""},"PeriodicalIF":9.6,"publicationDate":"2026-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148711038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both endocrine and immune responses are compromised during aging, along with impaired tissue regeneration, weakened pathogen detection, and decreased immune surveillance, and these events increase the susceptibility to infection, autoimmunity, cancers, and chronic disorders.

Increasing evidence indicates that chronic low-grade inflammation plays an important contributory role in its pathogenesis. The inflammatory microenvironment contributes to sarcopenia through complex interactions involving cellular senescence, mitochondrial dysfunction, and sustained inflammatory signaling, forming a self-reinforcing pathological cycle within skeletal muscle. This review synthesizes current evidence on the molecular mechanisms underlying inflammation-driven sarcopenia, with particular emphasis on how inflammatory signaling disrupts protein turnover and satellite cell metabolism. In addition, exercise is examined as a precision \"hormone-like\" intervention tailored to different sarcopenia phenotypes, highlighting the distinct mechanisms through which resistance training, aerobic exercise, and combined training modulate the senescence-associated phenotype and inflammatory responses. The review further evaluates anti-inflammatory therapeutic strategies, including nutritional interventions, pharmacotherapy, and acupuncture. These approaches improve muscle health by restoring immune balance, enhancing mitochondrial function, modulating the gut-muscle axis, reducing oxidative stress, and promoting the clearance of senescent cells. Finally, emerging precision medicine frameworks and multi-omics strategies that may support individualized sarcopenia management are discussed.
