Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

open access: yesBrain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

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

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

open access: yesBrain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

The medial entorhinal cortex keeps Up

open access: yesNature Neuroscience, 2012
A study reveals that medial entorhinal cortex layer III spiking dynamics shape the neocortical-hippocampal dialog during Up-Down state fluctuations in slow-wave sleep that may contribute to memory consolidation.

Clinicopathological and molecular heterogeneity of amyloid‐β in unnatural deaths under 70 years: A forensic autopsy–based study

open access: yesBrain Pathology, EarlyView.
This study investigates amyloid‐beta (Aβ) pathology in a forensic autopsy cohort of relatively young individuals (40–69 years). Using detailed immunohistochemical analyses of multiple Aβ species, we demonstrate marked regional and molecular heterogeneity, particularly within the striatum.

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 ...

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 ...

What makes a lonely child: environmental, health, and multimodal neuroimaging correlates of prospective loneliness in the ABCD study

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Loneliness in childhood is a growing public health concern, yet early multilevel candidate risk and protective factors remain insufficiently mapped. Systematic investigation is essential to guide prevention and intervention during sensitive developmental periods.

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.
