Maladaptive Inflammatory Signaling in Old Mice Impairs Colonic Regeneration by Promoting a Sustained Fetal‐Like Epithelial State

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
This study explores the impact of aging on regeneration of the mouse colonic epithelium. The authors find that old mice exhibit excessive and prolonged inflammation after infection with Citrobacter, resulting in the maintenance of a fetal regenerative state in epithelial cells, insufficient tissue repair, and death of the animal.

High p16INK4A expression in glioblastoma is associated with senescence phenotype and better prognosis

open access: yesNeoplasia: An International Journal for Oncology Research
Glioblastoma, isocitrate dehydrogenase (IDH)-wildtype (GBM), is the most malignant brain tumor in adults, with limited therapeutic intervention. Previous studies have identified a few prognostic markers for GBM, including the methylation status of O6 ...

Decellularized Aged Bruch's Membrane Confers Unique Biochemical Cues to Retinal Pigment Epithelium for In Vitro Modeling of Age‐Related Macular Degeneration

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
A Bruchs membrane (BrM) mimic based on aged decellularized BrM was developed and differentially expressed proteins in aged dECM‐BrM that may provide specific biochemical cues fundamental to model AMD in vitro were identified. RPE culture on aged dECM‐BrM developed certain AMD‐like features including reduced TEER and expression of drusen components ...

Aging‐Driven Immunosuppression: The Role of Tregs in the Ovarian Tumor Microenvironment

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
In the aged ovarian TME, cancer cells exhibit increased succinate production. Elevated extracellular succinate activates the SUCNR1 receptor on Tregs, promoting their recruitment and contributing to an immunosuppressive environment. This leads to diminished anti‐tumor T cell responses and reduced survival.

Multi‐Omics Signatures of Organ Clocks in Biological Aging and Disease: A Conceptual Framework for Organ‐Specific Aging Clocks

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Organ‐specific aging clocks integrating genomics, epigenomics, transcriptomics, proteomics, and metabolomics offer a more accurate assessment of biological aging than single‐omics approaches. This review proposes a multi‐omics framework emphasizing tissue data, longitudinal study designs, and clinically meaningful training outcomes to advance the ...

Global research trends in inflammaging from 2005 to 2024: a bibliometric analysis

open access: yesFrontiers in Aging
BackgroundInflammaging, defined as chronic low-grade inflammation associated with aging, is considered a key factor in many age-related diseases. Despite growing research, comprehensive assessments of trends and focuses on this field over the past 2 ...

Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria‐Mediated Intestinal Aging and Barrier Dysfunction

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Environmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.

Characterization of age-associated inflammasome activation reveals tissue specific differences in transcriptional and post-translational inflammatory responses

open access: yesImmunity & Ageing
Aging is associated with systemic chronic, low-grade inflammation, termed ‘inflammaging’. This pattern of inflammation is multifactorial and is driven by numerous inflammatory pathways, including the inflammasome.

Inflammaging: The Next Challenge—Exploring the Role of Gut Microbiota, Environmental Factors, and Sex Differences

open access: yesBiomedicines
The term ‘inflammaging’ has been coined to describe the chronic state of inflammation derived from ongoing cycles of tissue damage and the subsequent immune responses.

Aged Gut Microbiota Induces Mucosal Transcriptional Dysregulation, Impairing Immune Surveillance

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Aging impaired intestinal mucosal immune homeostasis by altering the epithelial barrier, lamina propria immune cells, follicle‐associated epithelium, and gut microbiota. These changes, particularly the accumulation of pro‐inflammatory bacteria in the gut microbiota, are closely associated with dysregulation of follicle‐associated epithelium gene ...
