Cellular senescence and the senescence-associated secretory phenotype (SASP)
Interventions that extend lifespan in animal models could, in principle, decelerate the aging process as a whole. Alternatively, they could act by suppressing one or more individual late-life pathologies that contribute to mortality. Here we …
Bisdemethoxycurcumin (BDMC) is a natural curcuminoid with higher solubility and stability than curcumin, yet its potential role in lifespan and healthspan regulation remains largely unexplored. This study aimed to investigate the effects of BDMC on …
This review examines how lysosomes—cellular recycling centers—actively regulate aging through two newly discovered signaling pathways (lysosomal surveillance response and transgenerational lysosomal signaling) and the protein TFEB. These findings suggest targeting lysosomal activity could be a …
Proliferating cells can enter an irreversible state of cell-cycle arrest known as cellular senescence. The accumulation of senescent cells contributes to organismal ageing and age-related pathologies. Consequently, therapeutic strategies have emerged to selectively eliminate senescent …
Cellular senescence is a major driver of age-related tissue dysfunction, characterized by chronic inflammation, oxidative stress, mitochondrial impairment, and disrupted extracellular matrix homeostasis. While senolytic strategies that eliminate senescent cells have shown therapeutic promise, irreversible …
Manganese (Mn) is an essential trace element, but excessive Mn exposure is associated with neurotoxicity and aging-related dysfunction. Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced …
Idiopathic pulmonary fibrosis (IPF) is characterized by failed alveolar epithelial repair and progressive fibrotic remodeling. Although aberrant reprogramming of alveolar type 2 (AT2) cells and accumulation of transitional AT2 states are increasing recognized as central …
This review synthesizes evidence that natural killer (NK) cells—a type of immune cell—undergo age-related changes that impair their ability to clear damaged cells and regulate inflammation, contributing to aging-related diseases. The authors propose NK cell …
Telomeres are sequences at chromosome ends that distinguish the natural end from a DNA break. Telomeres shorten at each round of cell division because the replisome cannot completely copy both DNA strands to the very …
This review examines how immunosenescence (age-related immune decline) drives lung diseases like COPD, fibrosis, and cancer, and surveys emerging treatments including senolytics, stem cell therapy, and lifestyle interventions. While it synthesizes current knowledge well, it's …
Partial reprogramming with Yamanaka factors effectively reverses cellular aging but poses potential oncogenic risks, limiting clinical translation. To identify safer rejuvenation induction factors (RIFs), we integrated five aging datasets and compared them with single-cell transcriptomics …
Lysosomal dysfunction is a prominent feature of neurodegeneration and aging, yet how primary defects in lysosomal trafficking are converted into progressive cellular decline remains poorly understood. Niemann Pick disease type C (NPC), caused by impaired …
Age is the dominant risk factor for cardiovascular disease, yet individuals of the same chronological age can differ markedly in the organs and biological pathways through which cardiovascular vulnerability emerges. We used deep learning to …
This review examines cellular senescence (aging cells that stop dividing) in muscle regeneration, finding that senescent cells play a dual role: they can briefly help repair muscle after injury, but when they accumulate in aging …
Researchers found that lifelong restriction of valine, a branched-chain amino acid in protein, improved metabolic health and reduced aging markers in both male and female mice, but only extended lifespan in males by 23%. The …
Researchers found that mocetinostat, a drug that inhibits certain histone deacetylases, selectively kills senescent (aged) chondrocytes—cells that accumulate in arthritic joints—while leaving healthy cells intact. This discovery could lead to a new class of "senolytic" …
This review examines 'partial reprogramming'—a technique that temporarily activates rejuvenation factors to reverse aging hallmarks in cells and tissues without turning them into cancer-prone stem cells. Early evidence suggests it can restore tissue function and …
Chemotherapeutic treatment of breast cancer with Doxorubicin (DOX) can induce tumor and stromal cell senescence leading to therapy-resistance. Senescence-associated secretory phenotype (SASP) promotes secretion of pro-inflammatory and tumorigenic factors causing systemic inflammation. Combined, this can …
Objectives: Rheumatoid arthritis (RA) synovitis frequently persists despite cytokine-targeted therapies, suggesting the existence of pathogenic stromal programs that sustain chronic inflammation independently of canonical immune pathways. Although synovial fibroblasts (SF) are increasingly implicated in treatment …
This review examines ginsenosides—compounds from ginseng—and their potential anti-aging effects through mechanisms like reducing cellular stress and supporting mitochondrial health. While promising in laboratory studies, the authors emphasize that moving from bench science to functional …
