Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire cell by switching "on" or "off" different genes through epigenetic changes. Mitochondria's signals can be so effective that, in yeast, fruit flies and worms, mild stress in mitochondria early in life can make the entire organism more resilient and live longer through a process called mitohormesis.
Senescent Microglia Secrete DLK1, Which Causes Dysfunction in the Aging Brain
Senescent cells accumulate with age in tissues throughout the body, disrupting tissue structure and function with inflammatory secretions. The growing burden of senescent cells is an important contributing cause of degenerative aging. A cell becomes senescent in response to damage induced by some form of stress, or more often when a somatic cell reaches the Hayflick limit on cellular replication. In youth senescent cells are efficiently cleared by the immune system, but immune system aging allows senescent cells to linger and grow in number. Immune cells themselves are prone to reaching the Hayflick limit and entering replicative senescence because they respond to a variety of issues with greater replication to multiply their efforts. Research into neurodegenerative conditions and the state of the aging brain has […]
Joint network analysis of non-motor symptoms and quality of life in patients with Parkinson’s disease
BackgroundNon-motor symptoms (NMS) are highly prevalent in Parkinson’s disease (PD) and are major determinants of declining quality of life (QoL), yet traditional statistical approaches are insufficient to capture the complex interactions between NMS and QoL. Network analysis offers a promising alternative for exploring these interactions.ObjectiveTo construct a joint network of non-motor symptoms (NMS) and quality of life (QoL) in patients with Parkinson’s disease (PD), identify core and bridge nodes, and inform precision nursing interventions.MethodsA convenience sample of 342 PD patients was recruited between January and June 2026 from the PD specialty outpatient clinic and neurology inpatient wards of a tertiary specialized hospital in Tianjin, and investigated using the Non-Motor Symptoms Scale (NMSS) and the Parkinson’s Disease Questionnaire-39 (PDQ-39). A joint network model was c
Ferroptosis–neuroinflammation interplay: mechanistic pathways and therapeutic opportunities in central nervous system disorders
Oxidative stress, iron dyshomeostasis, and chronic neuroinflammation are the principal mechanisms involved in the progression of central nervous system (CNS) disorders, which are a significant source of death and chronic disability worldwide. This review focuses on understanding the mechanistic relationship between ferroptosis and neuroinflammation in central nervous system (CNS) disorders, which involves the molecular mechanisms, their role in the pathogenesis of the disease, and therapeutic opportunities available. Ferroptosis is a regulated form of cell death triggered by iron-catalyzed lipid peroxidation, glutathione depletion and inactivation of glutathione peroxidase 4 (GPX4), resulting in neuronal injury. The increased generation of ROS in the cell due to the presence of excess iron catalyzes Fenton chemistry, which leads to lipid peroxidation of the cell membrane and ferroptotic
Engram cell vulnerability in neurodegeneration: from mechanistic insights to therapeutic horizons
Neurodegenerative diseases such as Alzheimer’s disease (AD), Parkinson’s disease (PD), and Huntington’s disease (HD) share progressive memory impairment, yet their upstream pathologies differ. This review synthesizes evidence across these disorders to frame memory decline through engram ensembles and proposes an excitability-vulnerability tradeoff, in which the physiological requirements for engram function, including elevated excitability, synaptic plasticity, and coordinated network activity, also increase sensitivity to synaptic stress, network disruption, and inflammatory perturbations. We summarize disease-related pathological cascades. To date, AD has the most robust body of direct experimental evidence linking pathology to impaired engram function. Solid experimental findings demonstrate that amyloid-β (Aβ)/tau causes hippocampal engram inaccessibility in AD. For PD and HD, infere
Advances in the treatment of age-related hearing loss: from molecular mechanisms to targeted interventions
Age-related hearing loss (ARHL) is the most common sensory disorder in older adults. Current hearing interventions, including hearing aids and cochlear implants, face limitations in accessibility and adherence. Therefore, efforts have been devoted to elucidating the molecular mechanisms underlying cochlear aging and identifying effective therapeutic targets for ARHL. This review summarizes several molecular mechanisms implicated in cochlear aging and ARHL, including autophagy dysregulation, oxidative stress, stereocilia degeneration, and dysregulation of mitochondrial dynamics. We further discuss recent advances in potential therapeutic targets and intervention strategies associated with these pathways, and provide theoretical support for targeted interventions for ARHL.
Inflammation and neuropsychiatric symptoms in Parkinson's disease: a genetic association
BackgroundThere has been some evidence that neuroinflammation is involved in Parkinson's disease (PD) and in psychiatric disorders.ObjectiveTo explore the effects of IL-1β rs16944 on PD patients' neuropsychiatric symptoms.MethodsTwo hundred and eighty-one consecutive PD patients underwent a neurological and neuropsychological evaluations, which included: Unified Parkinson's Disease Rating Scale, Schwab and England Activities of Daily Living scale, Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease—Anytime Short, Hospital Anxiety and Depression Scale and Dementia Rating Scale-2. The Neuropsychiatric Inventory (NPI) was also applied to patients' caregivers/informants. In addition to IL-1β rs16944, DRD3 rs6280 and GRIN2B rs7301328 were also genotyped. Non-parametric group comparisons and linear and logistic regressions were used for data analyses.ResultsThe IL-1β rs1694
Dogs may hold surprising clues to human longevity
Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ways to those seen in people. These metabolic “fingerprints” could offer clues about the biological processes that drive aging, including metabolism, inflammation, and cellular stress.
