Artificial intelligence–based 3D segmentation of tangle‐associated TDP‐43 in neurodegeneration

open access: yesBrain Pathology, EarlyView.
Multiplex immunostaining of anti‐phosphorylated TDP‐43, tau (AT8, pS396, TauC3, MN423, GT38), and Thioflavin S combined with AI‐based object recognition, reconstruction, and TAT maturation analysis pipeline in limbic regions revealed that distinct aggregation and tangle maturation patterns underscored region‐specific dynamics in the neurodegenerative ...

Early correlation of microglial activation with enhanced tumor necrosis factor-alpha and monocyte chemoattractant protein-1 expression specifically within the entorhinal cortex of triple transgenic Alzheimer's disease mice

open access: yesJournal of Neuroinflammation, 2005
Background Alzheimer's disease is a complex neurodegenerative disorder characterized pathologically by a temporal and spatial progression of beta-amyloid (Aβ) deposition, neurofibrillary tangle formation, and synaptic degeneration. Inflammatory processes

Neuropathology of a patient with Parkinson's disease and biallelic expansion in RFC1

open access: yesBrain Pathology, EarlyView.
This is the first report of neuropathology in biallelic RFC1 expansion‐associated Parkinson’s disease (PD). It shows a synucleinopathy of intraneuronal Lewy bodies consistent with the clinical PD diagnosis while neuropathological CANVAS (Cerebellar Ataxia with Neuropathy and bilateral Vestibular Areflexia) features were absent.

Entorhinal Layer II Calbindin-Expressing Neurons Originate Widespread Telencephalic and Intrinsic Projections

open access: yesFrontiers in Systems Neuroscience, 2019
In the present study we provide the first systematic and quantitative hodological study of the calbindin-expressing (CB+) principal neurons in layer II of the entorhinal cortex and compared the respective projections of the lateral and medial ...

Rate maintenance and resonance in the entorhinal cortex

open access: yesEuropean Journal of Neuroscience, 2010
AbstractThroughout the brain, neurons encode information in fundamental units of spikes. Each spike represents the combined thresholding of synaptic inputs and intrinsic neuronal dynamics. Here, we address a basic question of spike train formation: how do perithreshold synaptic inputs perturb the output of a spiking neuron?

Natural product‐derived TRPM7 channel inhibitors in neurological injury: Mechanisms, pharmacological potential and translational challenges

open access: yesBritish Journal of Pharmacology, EarlyView.
Disruption of intracellular ionic homeostasis is a convergent pathological feature across diverse neurological injuries and disorders, including ischaemic and haemorrhagic stroke, hypoxic–ischaemic brain injury, traumatic brain injury, epilepsy and brain tumour.

Driving Navigation in Older Adults Across the Alzheimer's Disease Continuum

open access: yesJournal of the American Geriatrics Society, EarlyView.
ABSTRACT Background and Objectives To examine whether time from amyloid positivity (amyloid time), a continuous measure of biological Alzheimer's disease (AD) progression, is associated with differences in navigation‐related driving behaviors among older adults.

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

open access: yesJournal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

open access: yesExperimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge
