Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, Volume 7, Issue 4, August 2026.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Recent Advances in the Molecular Mechanisms of Bacterial Anti‐Phage Defence Systems

open access: yesMicrobial Biotechnology, Volume 19, Issue 8, August 2026.
Panoptes as an example for an antiphage system consists of OptS producing a cyclic dinucleotide that prevents activation of OptE, a transmembrane protein. Phage T4 infection introduces the sponge protein Acb2 that adsorbs the cyclic dinucleotide thus activating OptE which disrupts the cell membrane aborting phage infection.

The Divergent Effects of Nicotinamide Riboside and High‐Intensity Exercise Training on Skeletal Muscle Epigenetic Aging

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
This study investigated the effects of nicotinamide riboside supplementation and high‐intensity interval training on skeletal muscle epigenetic aging. Our findings reveal that both interventions may modify epigenetic aging, with the muscle‐specific MEAT and DunedinPACE clocks showing the most responsiveness and links to mitochondrial abundance ...

Ammonia Metabolism in the Aging Liver: Emerging Mechanistic Insights

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Liver aging may weaken ammonia‐detoxification reserve by disrupting mitochondrial ureagenesis, GS‐mediated scavenging, glutamine metabolism, and metabolic zonation. This emerging framework links impaired nitrogen handling to potential hepatic stress amplification and systemic crosstalk, while highlighting the need for direct validation in physiological

Unveiling the AcSirt2‐FOXO‐Mitophagy Axis: Insights Into Mitochondrial Quality Control and Delayed Aging in Apis cerana

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Age‐related downregulation of AcSirt2 impairs mitochondrial homeostasis in old bees. AcSirt2‐mediated deacetylation of FOXO enhances transcriptional activity, upregulating antioxidant enzymes (SOD, CAT) and promoting PINK1/Parkin‐mediated mitophagy. This pathway facilitates autophagosome formation and clearance of damaged mitochondria, reducing ROS ...
