Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

iMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Coronal and Root Caries in Older Adults: Associated Factors, Quality of Life Impact, and Treatment—A Scoping Review

Gerodontology, EarlyView.
ABSTRACT Background Dental caries remains one of the most common chronic diseases affecting older adults worldwide. As edentulism decreases and more natural teeth are retained into old age, the number of susceptible tooth surfaces increases. Age‐related factors such as polypharmacy, cognitive decline, and reduced oral hygiene skills, together with ...

Centenarians, semi and supercentenarians, COVID-19 and Spanish flu: a serological assessment to gain insight into the resilience of older centenarians to COVID-19

Immunity & Ageing
Background Although it is well known that the older people have been the most susceptible to COVID-19, there are conflicting data on the susceptibility of centenarians.

Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.

Alzheimer's Protection by PLCγ2 Compacts Plaques, Redistributes Microglia, and Protects Synapses in AppNL‐G‐F Mice

Glia, Volume 74, Issue 8, August 2026.
The Alzheimer's disease protective PLCG2 P522R variant protects against amyloid‐induced synapse loss independently of amyloid load, promotes increased plaque compaction, and is associated with enhanced microglial engagement with diffuse amyloid. ABSTRACT The Alzheimer's disease protective P522R PLCG2 coding variant (rs72824905) is downstream of TREM2 ...

The Impact of Ageing on Skeletal Muscle: Roles of Mitochondrial Dysregulation, Systemic Communication, and Exercise

Journal of Cellular Physiology, Volume 241, Issue 8, August 2026.
ABSTRACT Ageing is a major risk factor for degenerative diseases, including sarcopenia, which is characterized by a progressive loss of skeletal muscle mass and function, frailty, and is associated with increased mortality. Skeletal muscle regeneration relies on muscle stem cells and efficient communication with cellular microenvironment.

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

VIEW, 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 ...

Neuropathology in a diverse cohort of oldest‐old: The LifeAfter90 study

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Studies of the oldest‐old show great neuropathologic heterogeneity; little is known in diverse populations after age 90. METHODS LifeAfter90 is a lifecourse cohort study of individuals aged ≥ 90 years evaluated every 6 months with optional brain donation; this study presents initial neuropathological findings.
