Nigrosome-1 neuromelanin and iron coupling in idiopathic and GBA-associated Parkinson disease reports that multimodal MRI captures PD-related nigral degeneration most strongly in nigrosome-1. The study quantified neuromelanin- and iron-sensitive MRI in 30 iPD, 26 GBA-PD and 30 healthy controls.
Key points
NM-sensitive nigrosome-1 markers gave the strongest patient-control discrimination, especially between GBA-PD and healthy controls.
The normal neuromelanin-iron coupling pattern was reversed in Parkinson disease subjects.

ADAPT AF-DES trial shows NOAC monotherapy reduced net adverse clinical events versus NOAC plus clopidogrel over 2 years. Presented at #TCT2026.
Key points
Presentation: TCT2026
Result: Fewer net adverse clinical events at 2 years with NOAC monotherapy versus NOAC plus clopidogrel

Orb2 amyloid structural landscape mapped across adult Drosophila lifespan
Orb2 amyloid structural landscape mapped across adult Drosophila lifespan reveals a dynamic, age-linked progression of amyloid states. Researchers identified age-dependent changes in Orb2 structure. The study is published in Cell (S0092-8674(26)01220-1).
Key points
Finding: dynamic, age-linked progression of amyloid states
Publication: Cell abstract S0092-8674(26)01220-1

Microglial NUS1 deficiency drives dopaminergic loss
Microglial NUS1 deficiency drives dopaminergic neurodegeneration through intercellular iron dysregulation. Ferroptosis inhibitor liproxstatin-1 alleviated neuron loss and PD-like symptoms in mouse models.
Key points
NUS1 deficiency in microglia disrupts intercellular iron homeostasis, causing neuronal iron overload.
Liproxstatin-1 treatment reduced dopaminergic neuron loss and improved motor deficits in mice.
