Senolytics and exercise: Dual modalities for rejuvenating muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

ACE‐inhibitory peptide Leu‐Tyr‐Ala in skeletal muscle actin exhibits anti‐aging effects through the inhibition of acn‐1 in Caenorhabditis elegans

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7002-7014, September 2026.
Abstract BACKGROUND Inhibitors of angiotensin‐converting enzyme (ACE) are used in pharmaceuticals and functional foods. Captopril, a well‐known ACE inhibitor, extends the lifespan of the nematode Caenorhabditis elegans. Bioactive peptides derived from food sources are considered safe ACE inhibitors.

JAPANESE QUAIL (COTURNIX JAPONICA) AS A MODEL OF ACCELERATED AGING OF HUMAN RETINAL PROCESSES. REPORT 1. ASSESSMENT OF THE AGE RPE LIPOFUSCIN ACCUMULATION DEPENDING ON THE RETINAL AMOUNT OF OXYCAROTENOIDS

open access: yesОфтальмохирургия, 2015
Purpose. Using the eyes of quails C. japonic as a model system to evaluate age-related accumulation of lipofuscin granules in the cells of the retinal pigment epithelium depending on the level of oxycarotenoids content in the retina and in the retinal ...

Regional astrocyte dysregulation and altered glymphatic‐related markers in Alzheimer's disease frontal cortex

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Astrocyte dysfunction is central to Alzheimer's disease (AD), yet expression patterns of astrocytic markers remain poorly defined. We measured Aquaporin‐4 (AQP4) and glial fibrillary acidic protein (GFAP) in post‐mortem frontal cortex of AD patients and controls across BrainNet Europe (BNE) stages.

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

open access: yesGlia, 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

open access: yesJournal 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.

Lighting Up the Retina: Fundus Autofluorescence Imaging in Retinal and Choroidal Diseases

open access: yesTNOA Journal of Ophthalmic Science and Research
Fundus autofluorescence (FAF) is a non-invasive imaging method that maps normal and abnormal retinal fluorophores, mainly lipofuscin. Although researched for decades, its major clinical use expanded significantly only in recent years. It has emerged as a
