Advances in the multifunctional roles of CX3CL1 in the central nervous system

13 hours 40 minutes ago
C-X3-C motif chemokine ligand 1 (CX3CL1), a structurally unique chemokine in the central nervous system (CNS), shapes physiological and pathological processes via specific binding to its receptor, C-X3-C motif chemokine receptor 1 (CX3CR1). Empirical evidence indicates that this signaling axis exerts dual neuroinflammatory effects: It restrains microglial hyperactivation, yet can promote inflammation under conditions such as chronic stress. Notably, it preserves synaptic plasticity and...

Blood-Based Biomarkers for Alzheimer's Disease: Advances in Early Detection and Monitoring of Age-Related Neurodegeneration

1 day 13 hours ago
Alzheimer's disease (AD) presents a critical global challenge, accounting for over 60% of the 57 million current dementia cases worldwide, with prevalence projected to exceed 100 million by 2050. Traditional diagnostic approaches, such as cerebrospinal fluid (CSF) analysis and neuroimaging are constrained by invasiveness, high costs, and limited accessibility, particularly problematic in aging population where early detection is crucial for effective intervention. This review synthesizes recent...

Should all MCI with Alzheimer's biological diagnosis receive anti-amyloid therapy?

1 day 13 hours ago
Our perspective addresses one of the most pressing and timely debates in contemporary neurology and health policy: whether the recent approval of anti-amyloid monoclonal antibodies for Alzheimer's disease should extend to all individuals with mild cognitive impairment (MCI; a large population of tens of millions of individuals worldwide mainly represented in Countries with aged population) who test positive for amyloid biomarkers, despite wide variability in prognosis and therapeutic response...

Mitochondrial DNA drives NLRP3-IL-1beta axis activation in microglia by binding to NLRP3, leading to neurodegeneration in Parkinson's disease models

1 day 13 hours ago
Dysregulated mitochondrial DNA (mtDNA) promotes inflammatory response and disease progression. However, the mechanism and role of mtDNA-mediated inflammatory activation in the pathogenesis of Parkinson's disease (PD) are not yet clear. This study demonstrates that the injection of mtDNA into the substantia nigra pars compacta induces PD pathology in mice, characterized by the loss of dopaminergic (DA) neurons and the activation of microglia. Transcriptomic profiling of magnetic-activated cell...

Impaired BDNF-TrkB trafficking and signalling in Down syndrome basal forebrain neurons

1 day 13 hours ago
Brain derived neurotrophic factor (BDNF) and its receptor tropomyosin-related kinase B (TrkB) play crucial roles in neuronal development, synaptic transmission, and neuroplasticity. Deficits in BDNF/TrkB signalling and trafficking have been identified in several neurodegenerative diseases, including Alzheimer's disease (AD). Individuals with Down syndrome (DS) are at an increased risk of developing AD compared to the general population. Basal forebrain neurons (BFNs) are among the first to...

Bridging global diversity gaps in Parkinson disease research

1 day 13 hours ago
The global burden of Parkinson disease (PD) is rapidly shifting towards low-income and middle-income countries (LMICs), which already account for 44% of all individuals with PD. Despite this trend, the populations of LMICs and other under-represented populations defined by ethnicity, sex, geography and minority groups within high-income countries remain largely excluded from PD research. The continuation of these disparities limits our knowledge of disease biology and restricts the applicability...

ICE: robust detection of cellular senescence from weak single-cell signatures using imputation-based marker refinement

1 day 13 hours ago
Detecting senescent cells from single-cell RNA-seq data remains challenging due to the weak and non-specific expression of canonical markers. Here, we demonstrate that simple expansion of these low-signal marker sets does not improve detection accuracy. To address this limitation, we develop ICE (Imputation-based Cell Enrichment), a computational framework that integrates expression imputation with marker refinement. ICE improves the detection of senescent cells in pancreatic β cells and...

Comparative effects of EXG and conventional therapies on muscle strength and balance in older people: A meta-analysis and meta-regression

1 day 13 hours ago
This systematic review with meta-analysis aimed to analyze the effects of exergaming (EXG) versus conventional therapies on muscle strength, balance, and fear of falling in healthy older people. A systematic literature search was conducted in six generic databases (PubMed, Medline, CINAHL Complete, Scopus, Cochrane Library, and Web of Science) with no start date restrictions until May 2025. The PRISMA, TESTEX, Rob 2 and GRADE tools were used to assess the methodological quality and certainty of...

Reactive oxygen species-activated bioorthogonal chemistry in living systems enabled by boronate-caged dihydrotetrazines

1 day 13 hours ago
Bioorthogonal chemistry has become a robust toolbox with growing applications in biology and medicine. To meet diverse needs in research, new types of on-demand bioorthogonal reactions capable of responding to biological triggers or exogenous stimuli are highly valuable, to achieve spatial and temporal control over reactions in living systems. Elevated levels of reactive oxygen species have been implicated in aging and multiple diseases, serving as remarkable endogenous triggers for prodrugs,...

Telomere shortening in laminopathic dilated cardiomyopathy

1 day 13 hours ago
Laminopathies are a group of rare disease due to mutations in the LMNA gene, which is crucial for nuclear integrity and cellular rigidity. Depending on the mutation, the disease manifests in striated muscles, adipose tissues, nerves, and the heart. Although many laminopathic patients exhibit accelerated aging syndromes, the connection as to why loss of LMNA drives aging remains unknown. Herein, we present evidence that cardiomyocytes from laminopathic heart sections exhibit shortened telomeres....
