Facile Synthesis of a Bis‐α‐aryl‐Substituted Pyclen‐Based Heptadentate Lanthanide Chelator for Ultra‐Robust and High‐Contrast MRI Agents and for Radiopharmaceuticals

Angewandte Chemie, EarlyView.
A facile synthesis involving a three‐component Petasis reaction is reported to construct bis‐α‐aryl‐substituted PCTAs. The synthesis is the simplest among all previously reported work on α‐substituted PCTAs. One of the isomers results in a Gd complex that showed significantly improved robustness despite being heptadentate and q = 2. This complex should

The Association of Amyloid‐β and Tau With Synaptic Dysfunction in Alzheimer's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the relative contributions of amyloid and tau to synaptic dysfunction in Alzheimer's disease (AD). Methods We included 109 cognitively unimpaired and impaired individuals from the Geneva Memory Center with available CSF synaptic biomarkers (neurogranin, SNAP‐25, GAP‐43). Participants were stratified according to amyloid (A)

Bivalent non-human gal-α1-3-gal glycan epitopes in the Fc region of a monoclonal antibody model can be recognized by anti-Gal-α1-3-Gal IgE antibodies

mAbs, 2023
Monoclonal antibody (mAb) production using non-human cells can introduce non-human glycan epitopes including terminal galactosyl-α1–3-galactose (α1–3-Gal) moieties. Cetuximab is a commercial mAb associated with causing anaphylaxis in some patients due to

A Two‐Stage Plasma Biomarker Algorithm Reduces Amyloid PET Use and the p‐Tau217 Gray Zone

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma p‐Tau217 leaves 30%–50% of patients in an indeterminate “gray zone” often requiring Aβ‐PET. We developed GRAD (Gatekeeper‐Reflex for Alzheimer's Disease), a two‐stage Aβ‐positivity prediction model to improve classification while reserving Aβ‐PET for residual uncertainty.
