Trajectories of plasma and CSF MTBR-tau243 and phosphorylated-tau species across the Alzheimer’s disease continuum

Lyduine Eisa Collij, Gemma Salvadó, Kanta Horie et al. · 2026 · Nature Communications

To efficiently implement plasma and cerebrospinal fluid (CSF) biomarkers for staging and prognosis of Alzheimer disease (AD), we must understand their dynamics across disease progression. We analyzed participants from the Swedish BioFINDER-2 study with mass spectrometry measurements of plasma and CSF tau species, including eMTBR-tau243/MTBR-tau243 and phosphorylation occupancies (%p-tau). Disease duration was estimated using Aβ-PET and tau-PET with the SILA algorithm. Bootstrapped LOESS models showed that %p-tau217 changes earliest, increasing just before Aβ-PET positivity.

Ferroptosis in cardiovascular diseases: molecular mechanisms and a novel therapeutic target

Suli Yu, Zhen Pang, Hong Fang et al. · 2026 · Molecular Biomedicine

Ferroptosis, a regulated cell death modality driven by iron accumulation and lipid peroxidation, has emerged as a pivotal pathophysiological mechanism across a broad spectrum of cardiovascular diseases (CVDs), which remain the leading cause of global mortality. Although robust preclinical evidence indicates that modulation of ferroptosis attenuates myocardial and vascular injury, clinical translation is constrained by incomplete understanding of context-specific roles, the paucity of validated biomarkers, and the absence of targeted therapeutics with acceptable safety profiles.

Population-scale sequencing resolves determinants of persistent EBV DNA

Sherry S. Y. Nyeo, Erin M. Cumming, Oliver S. Burren et al. · 2026 · Nature

Abstract Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum 1–3 . Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV D
