Cellular senescence and the senescence-associated secretory phenotype (SASP)
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 …
Age-related cognitive decline is a major public health concern, with few effective interventions available. Intermittent fasting (IF) has emerged as a promising metabolic intervention, potentially enhancing neuroprotection through increased β-hydroxybutyrate (BHB) production. This study aimed …
Astrocyte senescence (astrosenescence) has emerged as a potential mechanism through which ageing may progressively impair glial homeostatic neuronal support and render the brain more vulnerable to neurodegenerative diseases such as Parkinsons disease (PD). Yet human …
Researchers treated female mice with fatty liver disease (MASLD) using senolytic drugs—compounds that eliminate senescent (aged) cells—and found pregnancy rates improved, particularly through reduced aging and inflammation in the ovaries. However, the treatment had limited …
Transfer RNA (tRNA) halves (tRHs) are generated via the cleavage of tRNAs, but their roles in aging and longevity remain poorly understood. Here, we demonstrate a direct role of tRHs in aging in metazoans. Through …
Aging is increasingly recognized as a dynamic and potentially modifiable biological process, yet translation of mechanistic discoveries into clinically validated interventions that extend human healthspan remains limited. Because dermatologists can directly observe, sample, and quantify …
Clove (Syzygium aromaticum) extracts promote longevity in several model systems, yet the underlying molecular mechanisms responsible for the pro-longevity remain poorly defined. This study utilized a Saccharomyces cerevisiae model to investigate how clove extracts modulate …
Although lifespan has long been the focus of ageing research, preventing functional decline late in life is a more pressing societal need. Here, we investigate the basis of senescence and declining fitness during replicative ageing …
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 …
Pericytes are critical for maintaining blood-brain barrier (BBB) integrity and have emerged as key contributors to Alzheimer's disease (AD) pathogenesis. Although the apolipoprotein E2 (APOE2) allele is associated with reduced AD risk and increased longevity, …
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 …
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 …
Time-restricted feeding (TRF) is a promising dietary strategy for delaying metabolic aging, yet its efficacy in cardioprotection across metabolic stages remains poorly understood. This study demonstrates that a 10-h TRF window significantly mitigates cardiac aging …
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 …
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 …
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 …
Cancer progression and treatment failure are driven not only by genetic alterations but also by the remarkable capacity of tumor cells to adapt to metabolic stress, immune surveillance, and therapeutic pressure. Epigenetic plasticity provides a …
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 …
