Alzheimer’s Plasma Protein Structure Panel Reached AUCs Above 0.93

by GLOOM

MHD featured image for Alzheimer's plasma protein-structure biomarkers.

A 2026 Nature Aging study involving 520 participants found that plasma protein-structure signatures classified healthy control, mild cognitive impairment, and Alzheimer’s disease groups with 83.44% three-way accuracy.1 The result is a serious biomarker signal, but it is not a clinic-ready replacement for established Alzheimer’s testing. Research Highlights Classification was strong: The plasma structural-proteomics panel reached …

Trichostatin A for Alzheimer’s: 8 Core Genes, Unstable Binding

by GLOOM

MHD featured image for Trichostatin A and Alzheimer's disease gene networks.

A 2026 PLOS One computational study linked Trichostatin A to 949 predicted targets and 8 machine-learning-selected Alzheimer’s disease core genes, but 100 ns molecular dynamics simulations suggested the compound did not stably bind those candidate proteins.1 That makes the result more useful as an epigenetic network hypothesis than as evidence for a near-term Alzheimer’s drug. …

Brain Lymphatic MRI Shows Aging-Linked Drainage Changes

by GLOOM

MHD featured image for brain lymphatic MRI and aging-linked drainage changes.

A 2022 Nature Communications study used non-contrast 3D T2-FLAIR magnetic resonance imaging (MRI) to map human brain lymphatic signals in living people, including apparent channels from cranial nerves and skull-base structures toward cervical lymph nodes. Research Highlights Non-contrast MRI visualized lymphatic-like brain drainage: Albayram et al. identified dorsal dural signals near venous sinuses and ventral …

NMDAR/TRPM4 Death Complex Blocker Preserved Memory in Alzheimer’s Mice

by GLOOM

MHD featured image for the NMDAR/TRPM4 death complex, FP802, and Alzheimer's mouse-model memory protection.

A 2026 Molecular Psychiatry study found that oral FP802 disrupted the NMDAR/TRPM4 death complex and preserved memory-task performance in 5xFAD Alzheimer’s mice treated for 3 months.1 The finding is mechanistically sharper than a generic anti-amyloid claim: FP802 targeted a glutamate-toxicity complex downstream of amyloid stress. Research Highlights Complex formation was blocked: 5xFAD mice had increased …

PTP1B Inhibition Boosted Amyloid Clearance in Alzheimer’s Mice

by GLOOM

In APP/PS1 Alzheimer's model mice, deleting PTP1B or treating with the allosteric inhibitor DPM-1003 improved memory behavior, lowered amyloid burden, and pushed microglia toward SYK-driven clearance — a plausible mechanism, not a human treatment result yet.1 Research Highlights PTP1B loss improved behavior in APP/PS1 mice. Genetic deletion and DPM-1003 treatment improved novel object recognition and …

Microplastics and Parkinson’s Disease: 6 Plausible Brain-Risk Pathways

by GLOOM

MHD featured image for microplastics and neurodegenerative disease mechanisms.

A 2026 mechanistic review linked microplastics to 6 proposed Alzheimer’s disease pathways and 6 proposed Parkinson’s disease pathways.1 The calibrated interpretation is that microplastics are biologically plausible brain stressors, but the human evidence does not yet prove that they cause Parkinson’s disease or Alzheimer’s disease. Research Highlights Exposure is widespread: the review cited an estimate …

Entorhinal Dopamine Fails Early in Alzheimer’s Mice

by GLOOM

Editorial card showing the lateral entorhinal cortex with dopamine projections from the midbrain, illustrating an early-Alzheimer's mechanism finding rescued by L-DOPA in mice.

A 2026 Nature Neuroscience study from the Igarashi lab proposes a circuit-level answer for why the lateral entorhinal cortex (LEC) is the first cortical region to falter in Alzheimer’s: dopamine inputs from the VTA and substantia nigra to the LEC go functionally silent at the earliest disease stage in an APP knock-in mouse — before …
