Inflammaging and Dietary Interventions

• Chronic low-grade inflammation ("inflammaging") is a key driver of age-related pathologies including cardiovascular disease, neurodegeneration, and metabolic syndrome. Diet plays a dual role in modulating this process, acting both as a source of pro-inflammatory molecular patterns and as a delivery system for geroprotective compounds. Pro-inflammatory dietary components (advanced glycation end products, lipid peroxidation products, oxysterols, trans fats, and microbiome-derived metabolites) activate pattern recognition receptors and trigger inflammatory cascades, while anti-inflammatory bioactive compounds (polyphenols, omega-3 fatty acids, carotenoids, vitamins, and essential microelements) demonstrate potent anti-inflammatory properties through multiple mechanisms.

• Polyphenols (quercetin, EGCG, resveratrol, curcumin) inhibit pro-inflammatory signaling and activate sirtuin and Nrf2 pathways; omega-3 fatty acids reduce pro-inflammatory eicosanoids and increase specialized pro-resolving mediators; carotenoids, vitamins, and microelements (selenium, zinc, magnesium) suppress oxidative stress and modulate immune function.

Biological Aging Clocks

• Biological aging clocks track the pace of aging in individuals and their organs, tissues, and cells. These clocks have multiple potential use cases, including identifying people at high risk of disease, serving as a foundation for prevention or early detection, and determining whether lifestyle factors or interventions can modulate the aging process.

Senotherapeutics and Age-Related Diseases

• Targeting cellular senescence has emerged as a therapeutic strategy for age-related diseases. A novel tetrasubstituted cyclohexene-based small molecule (UCM-17017) decreases β-galactosidase activity in senescent human fibroblasts and selectively reduces the viability of senescent human lung adenocarcinoma cells over proliferative cells. This compound exhibits a favorable pharmacokinetic profile in vivo and induces a beneficial effect in a mouse model of pulmonary fibrosis. (source: arribas-lvarez-2026-discovery-of-novel-synthetic-cyclohexene-based-small-molecul.md)
• A senescent metabolism-modulating hierarchical scaffold, comprising an outer 3D-printed β-tricalcium phosphate (β-TCP) hollow tube and an inner freeze-casting MnTCP ceramic rod with the loading of nicotinamide mononucleotide (NMN), restores NAD+ homeostasis and redox balance for aged bone repair. This scaffold promotes new bone formation and maturation in aged rats with femoral condyle defects. (source: jiang-2026-a-senescent-metabolism-modulating-hierarchical-scaffold-restores-nad.md)
• CDK4/6 inhibition induces a senescence-associated secretory phenotype (SASP) via delayed NF-κB activation, which can induce inflammation in neighboring cells. Inhibiting NF-κB suppresses SASP gene expression without reversing stable arrest, suggesting SASP manipulation as a potential therapeutic strategy. (source: yeung-2026-cdk4-6-inhibition-induces-a-senescence-associated-secretory-phenotype.md)

Mitochondrial Dysfunction in Aging and Neurodegeneration

• Mitochondrial double-stranded RNA (mt-dsRNA) accumulation increases after midlife and coincides with reduced expression of mitochondrial RNA processing and translation machinery, along with increased expression of dsRNA antiviral signaling proteins, consistent with cytoplasmic mt-dsRNA-driven inflammation. In Alzheimer's disease brains, mt-dsRNA signatures are further increased and correlate with cognitive impairment, neuropathological severity, and AD risk genotypes. (source: doser-2026-transcriptomic-evidence-of-mitochondrial-double-stranded-rna-accumula.md)

Ovarian Aging

• Ovarian aging is characterized by chronic inflammation and granulosa cell (GC) senescence. A single-cell transcriptomic analysis revealed age-related shifts in ovarian cellular composition, including the enrichment of a pro-inflammatory NLRP3+ macrophage subpopulation and a senescence-associated GC subtype in aged ovaries. Wilms' tumor 1 (WT1) was identified as a candidate transcription factor upregulated in aged GCs and positively associated with p21 expression, suggesting a role in senescence-associated cell cycle arrest.

Osteoarthritis and Endocrine-Metabolic Imbalance

• Osteoarthritis (OA) is increasingly recognized as a whole-joint disorder shaped by the interplay between local tissue damage and systemic endocrine-metabolic imbalance. Endocrine factors (sex hormones, thyroid hormone, melatonin, parathyroid hormone, and vitamin D) and metabolic disturbances (obesity, insulin resistance, dysregulated glucose and lipid metabolism, and gut microbiota imbalances) cooperatively remodel the joint microenvironment, promoting extracellular matrix degradation, persistent synovitis, and uncoupled bone-cartilage remodeling.

Digital Technologies for Healthy Longevity

• Digital technologies can extend preventive and personalised care, foster independence, and enhance participation across the life course. Policies must ensure that technologies respect human rights, protect autonomy, and strengthen social relationships and professional care. Investment in interoperable infrastructure, participatory design, and ethical and legal safeguards is essential to realize the potential of digital health for healthy longevity. (source: braune-2026-digital-technologies-for-healthy-longevity-a-policy-agenda.md)
• Digital light processing (DLP) bioprinting offers superior spatial resolution, rapid printing speed, and gentle cell handling compared to extrusion- and inkjet-based methods. Recent advances in bioink development (including methacrylated natural polymers, decellularized extracellular matrix (dECM)-derived hydrogels, hybrid nanocomposites, and cell-laden formulations) have significantly expanded the biofabrication landscape. These materials enable the creation of constructs that closely mimic native tissues such as corneas, cartilage, liver, and skeletal muscle in terms of structural and biochemical complexity.

Anti-Aging Pharmacology

• Anti-aging pharmacology has transitioned to a hallmark-informed, multi-level framework integrating mechanistic, preclinical, and translational evidence. The field converges on three intervention axes: senotherapeutics targeting cellular senescence and SASP signaling, nutrient-sensing and metabolic gerotherapeutics modulating mTOR, AMPK, autophagy, and mitochondrial adaptation, and homeostasis-restoring agents reinforcing redox, inflammatory, and circadian resilience.

Microglial Repopulation and Neurological Disorders

• Microglial repopulation after depletion via colony-stimulating factor 1 receptor (CSF1R) inhibition primarily involves proliferation of surviving microglia but can recruit nonmicroglial progenitors when depletion is exhaustive. These insights guide therapeutic strategies for microglial replacement treatment in neurological disorders. (source: wang-2026-surviving-microglia-and-nonmicroglial-progenitors-contribute-to-microg.md)

Mitochondrial ROS and Plasma Cell Longevity

• The cytokine receptor TACI is essential for long-lived plasma cell (LLPC) survival by inhibiting mitochondrial reactive oxygen species (ROS) accumulation. Pharmacologic antioxidant treatment with N-acetylcysteine mitigates ROS accumulation, rescues LLPC numbers, and enhances influenza vaccine efficacy in vivo.

Stress Responses in Pancreatic β-Cells

• IFNα exposure and DNA damage elicit distinct stress responses in human donor islets and induced pluripotent stem cell-derived islet cells (SC-islet cells). While IFNα induces a classical IFN response involving HLA Class I genes and ER stress genes, bleomycin-induced DNA damage leads to signatures of senescence without affecting IFN genes. (source: akbari-2026-ifn-and-bleomycin-induced-dna-damage-activate-distinct-stress.md)

Obesity and Longevity in Captive Great Apes

• Great apes in zoos exhibit high rates of overweight and obesity, with females showing higher prevalence than males. This is attributed to diets low in fiber and high in easily digestible carbohydrates, such as cultivated fruit and pelleted feeds. Obesity prevention is crucial for optimizing health span in these long-living species. (source: meireles-2026-global-data-from-great-ape-zoo-populations-confirm.md)

Extracellular Vesicles in Chronic Lung Diseases

• Extracellular vesicles (EVs) released by senescent cells play a critical role in chronic lung diseases by promoting inflammation, fibrosis, tissue remodeling, and cellular senescence. Specific microRNAs and proteins within EVs, such as miR-21 and miR-34a, are key factors in disease progression. EVs also hold therapeutic potential for targeted drug delivery and immune modulation.

Dietary Patterns and Gut Microbiota

• A dietary index for gut microbiota (DI-GM) is inversely associated with all-cause and cardiovascular disease mortality. A corresponding metabolic signature explains over 50% of the association between DI-GM and mortality risk, highlighting the importance of dietary patterns that support gut microbiota health for longevity.

Epigenetic Aging in Type 2 Diabetes

• Distinct epigenetic aging patterns are observed in type 2 diabetes subgroups, with severe insulin-resistant diabetes showing accelerated aging and increased renal vulnerability. Hypomethylation at TXNIP is associated with faster aging and kidney function decline, suggesting potential targets for geroscience-guided interventions. (source: gurung-2026-distinct-epigenetic-ageing-patterns-are-associated-with-heterogeneit.md)

Thymic Aging and Immune Function

• Age-associated thymic involution leads to reduced T-cell production, contributing to immunosenescence and increased vulnerability to cancer, infections, and autoimmune disorders. Activation of GPR40 by the agonist GW9508 restores thymic function in aged mice by elevating intracellular calcium ion levels, activating the AMPK signaling pathway, and inhibiting the hyperactivation of the ERK1/2-MAPK pathway in senescent thymic epithelial cells. (source: li-2026-gw9508-induced-activation-of-gpr40-in-thymic-epithelial-cells.md)

Skin Aging and Inflammation

• GRWD1 is identified as a novel signature in skin aging, suppressing IRF3-mediated IFN pathway activation and alleviating inflammatory responses. Overexpression of GRWD1 decreases IFN pathway gene expression and reduces age-related markers such as p16, IL-6, and IL-8, suggesting its potential as a therapeutic target.
