Scientists discover tiny gut particles that may drive aging and chronic disease

A new study suggests microscopic particles from the gut may actively drive inflammation and chronic diseases associated with aging. Remarkably, gut particles from young animals appeared to counter some aging-related damage in older animals, hinting at new possibilities for future treatments.

Human Mind in a Theistic World

What happens to the human mind if God exists? Louis Caruana argues that mind, soul, and body are not separate entities but dimensions of a single human individual — challenging both strong dualism and reductive materialism while reframing what could survive death.

Fisetin Attenuates D-Gal-Induced Ovarian Aging by Modulating Mitophagy via the AMPK/mTOR Pathway

This study aimed to explore the alleviating effects of fisetin, a polyphenolic flavonoid, on ovarian dysfunction in a D-galactose (D-gal)-induced aging mouse model, as well as the underlying mechanisms, using both in vivo and in vitro experiments. Mice were subcutaneously injected with D-gal (100 mg/kg/day) for 60 days to establish the ovarian aging model; during the final 30 days, fisetin (10, 20, 30 mg/kg/day) was given orally. In addition, a senescent model of granulosa cell (GC) was established using D-gal and treated with fisetin. Fisetin supplementation improved ovarian endocrine function and reproductive capacity in aging mice, as reflected by regularized estrous cycles, elevated estradiol levels, and increased embryo numbers.

This study aimed to explore the alleviating effects of fisetin, a polyphenolic flavonoid, on ovarian dysfunction in a D-galactose (D-gal)-induced aging mouse model, as well as the underlying mechanisms, using both in vivo and in vitro experiments. Mice were subcutaneously injected with D-gal (100 mg/kg/day) for 60 days to establish the ovarian aging model; during the final 30 days, fisetin (10, 20, 30 mg/kg/day) was given orally. In addition, a senescent model of granulosa cell (GC) was established using D-gal and treated with fisetin. Fisetin supplementation improved ovarian endocrine function and reproductive capacity in aging mice, as reflected by regularized estrous cycles, elevated estradiol levels, and increased embryo numbers. Furthermore, fisetin reduced the number of atretic follicles and the extent of ovarian fibrosis and senescence, while simultaneously restoring the proliferation-apoptosis balance in follicular GCs, as well as alleviating oxidative stress. RNA-sequencing revealed that AMP-activated protein kinase (AMPK)/mechanistic target of rapamycin (mTOR) signaling and mitophagy were involved in the protective effects of fisetin against ovarian aging. Consistently, fisetin treatment promoted mitophagy, accompanied by AMPK/mTOR activation in ovarian tissues and GCs following D-gal exposure. Inhibition of AMPK attenuated the effect of fisetin on mitophagy. Additionally, blockage of mitophagy also reversed the beneficial effects of fisetin on mitochondrial injury, oxidative stress, cell cycle arrest, and cellular senescence in D-gal-induced senescent GCs. These findings indicate that fisetin prevents ovarian aging by suppressing follicular GC oxidative damage and ameliorating cell cycle arrest via activation of AMPK/mTOR-mediated mitophagy, thereby preserving female fertility.

Sleep Duration Linked to Accelerated Aging

The relationship between sleep and disease suggests that there exists a connection between the brain and the body that extends beyond merely influencing the brain itself.

Among brain-related disorders, short sleep was significantly associated with depressive episodes and anxiety disorders, as seen in other studies of sleep and mental health. Short sleep was also associated with obesity, type 2 diabetes, hypertension, ischemic heart disease, and heart arrhythmias.

Short and long sleep were associated with chronic obstructive pulmonary disease, asthma, and a cluster of digestive disorders, including gastritis and gastroesophageal reflux disease.

Enhancing Non-small Cell Lung Cancer Susceptibility to Anti-PD-1/PD-L1 Therapy through PD-L1 Ligand–Ir(III) Complex Conjugates

Immunotherapy targeting programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) has transformed the management of several types of cancers, including non-oncogene-addicted non-small cell lung cancer (NSCLC) [1], although its efficacy remains limited by resistance mechanisms and constraints inherent to monoclonal antibodies [1]. To overcome these drawbacks, small-molecule PD-L1 inhibitors have been developed, and we previously contributed by identifying the nanomolar triazine-based ligand Tr-10 [2]. In parallel, combinatorial strategies aimed at improving the efficacy of anti-PD-1/PD-L1 immunotherapy have gained increasing attention. Notably, platinum-based chemotherapy combined with immune checkpoint inhibitors is recommended as a first-line treatment for advanced NSCLC with PD-L1 expression <50% [3]. Here, we investigated a novel combination involving our anti-PD-L1, Tr-10 [2], and a bis(phenyl-pyridine)iridium(III) complex, Ir-2 (Fig. 1A) [4]. Iridium (Ir) complexes, unlike platinum drugs, are chemically inert and induce endoplasmic reticulum (ER) stress and overproduction of reactive oxygen species (ROS) [5,6], both culminating in damage-associated molecular pattern (DAMP) release and immunogenic cell death (ICD). Moreover, their photophysical properties enable PD-L1-targeted bioimaging when coupled with PD-L1 ligands (Fig. S1) [7].

Immunosenescence and Inflammaging as Drivers of Neurodegeneration: Cellular Mechanisms, Neuroimmune Crosstalk, and Therapeutic Implications

Aging is accompanied by profound alterations in immune function, termed immunosenescence, and by a chronic, low-grade inflammatory state known as inflammaging. These processes are increasingly recognized as central drivers of age-related neurodegenerative diseases, including Alzheimer’s Disease, Parkinson’s Disease, Amyotrophic Lateral Sclerosis and Multiple Sclerosis. In the central nervous system, senescent microglia and astrocytes lose their homeostatic and neuroprotective functions, while systemic immune aging and blood–brain barrier dysfunction further amplify neuroinflammation and impair protein aggregate clearance. This sustained pro-inflammatory environment promotes synaptic dysfunction, neuronal loss and cognitive decline.
