Plasma biomarker progression across the Alzheimer's disease amyloid beta and tau positron emission tomography trajectories

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION With increased uptake in disease‐modifying treatments for amyloid beta (Aβ) removal, it is important to measure performance of highly sensitive plasma biomarkers to detect the presence of Aβ and tau in cognitively impaired populations.

Deep cervical lymphatic–venous anastomosis attenuates cognitive dysfunction and biomarker abnormalities in severe Alzheimer's disease: A prospective single‐arm study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION This study evaluated the efficacy of deep cervical lymphatic–venous anastomosis (dcLVA) for severe Alzheimer's disease (AD). METHODS A total of 139 severe AD patients undergoing dcLVA were enrolled, and changes in cognitive function and biomarkers were evaluated by comparing preoperative measures with postoperative outcomes over a

Temporal dynamics of white matter hyperintensities related to Alzheimer's disease in adults with Down syndrome

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION White matter hyperintensities (WMH) are common in Down syndrome (DS), yet their longitudinal evolution and associations with Alzheimer's disease (AD) remain unclear. METHODS Longitudinal MRI study, including 80 DS adults and 53 euploid controls. WMH were segmented on serial FLAIR using a longitudinal pipeline.

Female‐biased astrocytic priming shapes early locus coeruleus vulnerability in an Aβ oligomer milieu

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The locus coeruleus (LC) is an early site of Alzheimer's disease (AD) pathology, yet the role of brainstem astrocytes in early, sex‐dependent vulnerability remains unclear. METHODS In 2‐ to 3‐month‐old APP/PS1 mice, we combined in vivo proton magnetic resonance spectroscopy (MRS) of the brainstem with region‐resolved molecular ...

Targeted blood proteome profiling using NULISAseq identifies a high‐performance biomarker panel for Aβ pathology quantification and staging

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION While current blood‐based biomarkers for Alzheimer's disease (AD) are effective for determining amyloid beta (Aβ) pathology positivity/negativity, they are insufficient for quantifying Aβ plaque deposition. METHODS We profiled 325 plasma proteins in a Hong Kong Chinese cohort using the Nucleic Acid Linked Immuno‑Sandwich Assay ...

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 451-470, February 2026.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Engineering a Perfusion Bioreactor System for hiPSC‐Derived Progenitor Co‐Culture Capturing Microglial Features in CNS Development

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 2, Page 363-378, February 2026.
The authors report the development of a controlled and scalable 3D co‐culture system combining hiPSC‐derived erythromyeloid progenitors and neurospheres within the Ambr® 250 Modular platform operated with a newly designed perfusion system. This model faithfully recapitulates early microglia–neural interactions, enabling progenitor integration ...
