This disparity, paired with the increasingly aged populations of Western nations, poses a palpable predicament to public health and the economy. Deterioration of the skeletal muscle system is a key contributor to illness, loss of independence, and diminishing healthspan. Muscle quality correlates to longevity due to its significant role in metabolic homeostasis and autonomous mobility, reducing instances of adverse events such as falls and fractures. The age-related loss of muscle mass and function is termed sarcopenia, affecting older adults ubiquitously without intervention through regular resistance training. Although clinical manifestations of sarcopenia are well characterized, the molecular mechanisms underlying its pathogenesis remain incompletely understood, limiting the development of targeted, mechanism-based interventions. To identify interventions beyond exercise that delay sarcopenia, it is necessary to identify early onset physiological alterations defining this process. Genetically modified mouse models of accelerated or delayed aging offer valuable insight into the cellular mechanisms that drive or mitigate sarcopenia. The latter is often achieved by disrupting the somatotropic axis, as multiple models exist that either lack growth hormone (GH) production or a functional GH receptor (GHR) paired with a secondary deficiency in insulin like growth factor-1 (IGF-1), which reliably extends lifespan across various species. This review evaluates GH’s paradoxical role in muscular maintenance and contrasts the skeletal muscle health of various murine models of aging in effort to better outline the molecular underpinnings of sarcopenia.</div></div>","PeriodicalId":55545,"journal":{"name":"Ageing Research Reviews","volume":"113 ","pages":"Article 102946"},"PeriodicalIF":12.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145558626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatic autophagy dysfunction can increase free fatty acids, which attack the blood-brain barrier and lead to neurodegenerative diseases.

A neurodegenerative condition called Alzheimer's disease is marked by cognitive deterioration. It is increasingly recognized as being influenced by impaired mitochondrial function and mitophagy, the selective degradation of damaged mitochondria. Serotonin, a neurotransmitter traditionally known for its role in mood regulation, has emerged as a critical modulator of mitochondrial dynamics and quality control through its interaction with key pathways such as the PINK1-Parkin and cAMP/PKA signaling pathways. In AD, alterations in serotonin levels and receptor function are associated with disruptions in mitophagy, leading to the accumulation of dysfunctional mitochondria, increased oxidative stress, and subsequent neuronal damage. This review synthesizes current evidence that links serotonin dysregulation to mitochondrial pathology in AD, exploring how impaired serotonin signaling exacerbates mitochondrial dysfunction and contributes to amyloid-beta (Aβ), phosphorylation of Tau (p-Tau) accumulations, and increased neuroinflammation. Additionally, we assessed the therapeutic potential of serotonin-targeting agents, particularly selective serotonin reuptake inhibitors (SSRIs), in restoring mitophagy, enhancing mitochondrial integrity, and attenuating neurodegeneration. By highlighting existing knowledge gaps and key controversies, this review underscores the promise of serotonin-mitochondria pathways as novel therapeutic targets and advocates for focused investigation into receptor-specific, mitophagy-centered interventions for AD.</div></div>","PeriodicalId":55545,"journal":{"name":"Ageing Research Reviews","volume":"114 ","pages":"Article 102957"},"PeriodicalIF":12.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145643601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This progressive process needs adaptable drivers to push it forward. The redox-sensitive high mobility group box 1 (HMGB1) protein is a perfect example of this kind of oxidative stress- and aging-related multifunctional protein. The HMGB1 protein is an important non-histone DNA chaperone which maintains chromatin integrity and contributes to gene expression and DNA repair. Diverse intrinsic and exogenous insults induce the translocation of the nuclear HMGB1 protein into cytoplasm and subsequently into the extracellular space. Interestingly, cellular senescence is associated with a robust release of HMGB1 from chromatin and subsequently it is secreted with other SASP factors. The extracellular HMGB1 is a pleiotropic immune regulator since it can organize both proinflammatory and immunosuppressive responses in a context-dependent manner. For instance, HMGB1 stimulates proinflammatory responses via TLR and RAGE signaling as well as by activating NLRP3 inflammasomes and cooperating with the complement system. HMGB1 can also delay the resolution of acute inflammation and thus elicit chronic inflammation. An increase in chemotaxis of myeloid cells by HMGB1 stimulates the recruitment of immunosuppressive cells, such as MDSCs and Tregs. HMGB1 also promotes the polarization of M1 macrophages toward the immunosuppressive M2 phenotype and enhances the function of inhibitory immune checkpoints. Given that the redox-sensitive HMGB1 protein is a driver of cellular senescence and a multifunctional regulator of the immune network, it seems that HMGB1 has a crucial role in the inflammaging process.</div></div>","PeriodicalId":55545,"journal":{"name":"Ageing Research Reviews","volume":"113 ","pages":"Article 102926"},"PeriodicalIF":12.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145364814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
