IGSF10 is a RET antagonist regulating Ewing sarcoma growth and GnRH neuron migration

8 months ago
RET is a receptor tyrosine kinase that plays important roles in development, cancers, and Parkinson's disease. Here, we identify immunoglobulin superfamily member 10 (IGSF10) as a RET antagonist. We show that Ewing sarcoma depends on IGSF10 and that IGSF10 prevents RET-mediated activation of cdc42, a Rho family G protein and a key regulator of Ewing sarcoma growth as well as cell migration. We demonstrate that IGSF10 binds RET and GAS1, a cell surface RET inhibitor, and assembles an inhibitory...

The evolution of Alzheimer's disease: From mitochondria to microglia

8 months ago
Alzheimer's disease (AD) represents the most prevalent neurodegenerative disorder worldwide. Recent studies highlights that mitochondrial dysfunction drives alterations in microglial function, serving as a pivotal mechanism in the pathogenesis and progression of AD. Increasingly, there is evidence that mitochondrial dysfunction encompasses energy metabolism deficits, heightened oxidative stress, impaired mitochondrial dynamics, disrupted autophagy, and calcium homeostasis imbalances. These...

Micro/nanoplastic-driven cardiovascular senescence and multi-target intervention by traditional Chinese medicine

8 months ago
Micro/nanoplastics (MNPs), pervasive environmental pollutants, accumulate in cardiovascular tissues and drive premature aging through multiscale pathophysiological cascades. This review synthesizes evidence establishing environmental phenotypic aging as a novel mechanistic link between MNP exposure and cardiovascular senescence. MNPs induce mitochondrial damage involving cristae disruption and mtDNA leakage activating cGAS-STING, epigenetic reprogramming encompassing METTL3-mediated m6A...

Choroid plexus-mediated CSF secretion remains stable in aging rats via high and age-resistant metabolic activity

8 months ago
Our brain is bathed in cerebrospinal fluid (CSF) that is produced by the choroid plexus. CSF serves as a dispersion route for hormones and nutrients, and a conduit for waste clearance. Age-dependent reduction in the CSF secretion rate could influence cerebral waste clearance and thereby promote cognitive deficits in the elderly. Here, we resolve age-dependent modulation of CSF dynamics and choroid plexus function by complementary in vivo determinations of intracranial pressure (ICP) and CSF...

Nipah virus vaccines evaluated in pigs as a 'One Health' approach to protect public health

8 months ago
Nipah virus (NiV) causes a severe neurological disease in humans. The first NiV outbreak, in Malaysia, involved pig-to-human transmission, that resulted in significant economic losses to the local pig industry. Despite the risk NiV poses to pig-dense regions, no licensed vaccines exist. This study therefore assessed three NiV vaccine candidates in pigs: (1) adjuvanted soluble NiV (s)G protein, (2) adjuvanted pre-fusion stabilised NiV (mcs)F protein, and (3) adenoviral vectored NiV G (ChAdOx1 NiV...

Identification of gut microbiota causally associated with aging and longevity and mediation roles of the cerebrospinal fluid proteins: proteomic genetic evidence from Mendelian randomization

8 months ago
Gut microbiota (GM) is implicated in aging biology, yet its dual regulatory role in the distinct yet interconnected processes of lifespan extension and aging remains poorly understood. This study employed genetic approaches to identify GM taxa exerting causal effects on longevity and aging and assess the mediation role of cerebrospinal fluid (CSF) proteins. We leveraged summary statistics of the GM taxa (207 taxa, 7738 participants from the Dutch Microbiome Project), the CSF proteins (7008...

Large language model-based biological age prediction in large-scale populations

8 months ago
Accurate and convenient assessment of individual aging is crucial for identifying health risks and preventing aging-related diseases. Nonetheless, current aging proxies often face challenges such as methodological limitations, weak associations with adverse outcomes and limited generalizability. Here we propose a framework that leverages large language models (LLMs) to estimate individual overall and organ-specific aging using only health examination reports. We validated this approach across...

Advancing multiple sclerosis management in older adults

8 months ago
Multiple sclerosis (MS) typically presents in early to middle adulthood, but owing to advancements in health care, many individuals with MS now live a normal lifespan, and approximately half of the people currently living with MS are ≥50 years of age. As people living with MS age, their diagnosis, treatment and disease management become more complex owing to the effects of ageing, immunosenescence and comorbidities. Furthermore, diagnosis of late-onset MS (onset above 50 years of age) often...

Altered automatic gaze processing in older adults

8 months ago
From understanding others' mental states to interpreting social cues, aging impairs social abilities. These impairments might not seem surprising given they rely on other cognitive functions such as memory, attention and decision-making, which are known to decline with age. It is, however, unclear to what degree impairments of more basic perceptual abilities, such as eye-gaze detection, contribute to or even precede the decline in social skills. Previous studies have obtained mixed results when...
