  • Phenylketonuria.

    Francjan J van Spronsen, Nenad Blau, Cary Harding 他 · Nature reviews. Disease primers · 2021

    Phenylketonuria (PKU; also known as phenylalanine hydroxylase (PAH) deficiency) is an autosomal recessive disorder of phenylalanine metabolism, in which especially high phenylalanine concentrations cause brain dysfunction. If untreated, this brain dysfunction results in severe intellectual disability, epilepsy and behavioural problems. The prevalence varies worldwide, with an average of about 1:10…

  • Genetic etiology and clinical challenges of phenylketonuria.

    Nasser A Elhawary, Imad A AlJahdali, Iman S Abumansour 他 · Human genomics · 2022

    This review discusses the epidemiology, pathophysiology, genetic etiology, and management of phenylketonuria (PKU). PKU, an autosomal recessive disease, is an inborn error of phenylalanine (Phe) metabolism caused by pathogenic variants in the phenylalanine hydroxylase (PAH) gene. The prevalence of PKU varies widely among ethnicities and geographic regions, affecting approximately 1 in 24,000 indiv…

  • Phenylketonuria and the brain.

    Valentina Rovelli, Nicola Longo · Molecular genetics and metabolism · 2023

    Classic phenylketonuria (PKU) is caused by defective activity of phenylalanine hydroxylase (PAH), the enzyme that coverts phenylalanine (Phe) to tyrosine. Toxic accumulation of phenylalanine and its metabolites, left untreated, affects brain development and function depending on the timing of exposure to elevated levels. The specific mechanisms of Phe-induced brain damage are not completely unders…

  • The effects of long-term high-altitude exposure on cognition: A meta-analysis.

    Rui Su, Shurong Jia, Niannian Zhang 他 · Neuroscience and biobehavioral reviews · 2024

    Long-term high altitudes (HA) exposure's impact on cognition has yielded inconsistent findings in previous research. To address this, we conducted a meta-analysis of 49 studies (6191 individuals) to comprehensively evaluate this effect. Moderating factors such as cognitive task type, altitude (1500-2500 m, 2500-4000 m, and above 4000 m), residential type (chronic and lifelong), adaptation level an…

  • Astrocytic Piezo1-mediated mechanotransduction determines adult neurogenesis and cognitive functions.

    Shaopeng Chi, Yaxiong Cui, Haiping Wang 他 · Neuron · 2022

    Adult brain activities are generally believed to be dominated by chemical and electrical transduction mechanisms. However, the importance of mechanotransduction mediated by mechano-gated ion channels in brain functions is less appreciated. Here, we show that the mechano-gated Piezo1 channel is expressed in the exploratory processes of astrocytes and utilizes its mechanosensitivity to mediate mecha…

  • Sepiapterin for the treatment of phenylketonuria.

    Robin A Williams, Damon A Bell, Amanda J Hooper 他 · Expert opinion on pharmacotherapy · 2025

    Phenylketonuria (PKU) is an autosomal recessive inborn error of phenylalanine (Phe) metabolism resulting from deficiency of phenylalanine hydroxylase (PAH). Untreated, PKU may result in severe and irreversible intellectual impairment due to marked hyperphenylalaninemia (HPA). Guidelines recommend lifelong reduction in Phe levels, usually achieved via a strict low-protein diet and sometimes medicat…

  • Parkinson's disease as a somato-cognitive action network disorder.

    Jianxun Ren, Wei Zhang, Louisa Dahmani 他 · Nature · 2026

    Parkinson's disease (PD) is an incurable neurological disorder that often begins insidiously with sleep disturbances and somatic symptoms, progressing to whole-body motor and cognitive symptoms1-5. Dysfunction of the somato-cognitive action network (SCAN)-which is thought to control action execution6,7 by coordinating arousal, organ physiology and whole-body motor plans with behavioural motivation…

  • Association of Cumulative Blood Pressure With Cognitive Decline, Dementia, and Mortality.

    Chenglong Li, Yidan Zhu, Yanjun Ma 他 · Journal of the American College of Cardiology · 2022

    Elevated blood pressure (BP) has been linked to impaired cognition and dementia in older adults. However, few studies have accounted for long-term cumulative BP exposure. The aim of this study was to test whether long-term cumulative BP was independently associated with subsequent cognitive decline, incident dementia, and all-cause mortality among cognitively healthy adults. This study used data f…
