Rituximab Binding Endows CD20+ Extracellular Vesicles With NK Cell‐Activating Properties in B Cell Lymphoma

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
B cell lymphoma‐derived EVs are intrinsically neutral or suppressive with respect to NK cell activity (panel 1). In the context of rituximab treatment, NK cytotoxicity is enhanced by antibody‐dependent cell‐mediated cytotoxicity (panel 2). Herein we show that, in addition, rituximab recognition of EV‐associated CD20 generates immune complexes that ...

Biomolecular Corona of Extracellular Vesicles: Report on Isev Workshop

Journal of Extracellular Biology, Volume 5, Issue 8, August 2026.
ABSTRACT The concept of the “biomolecular corona” (BC) was first introduced to describe the spontaneous absorption of molecules, mainly proteins, onto the surface of synthetic nanoparticles upon exposure to biological fluids. More recently, the same term has been used to describe biomolecules that dynamically interact with the surface of extracellular ...

Cementum Attachment Protein‐Derived Peptides Modulate Brushite and Calcium Oxalate Crystallization In Vitro

Journal of Peptide Science, Volume 32, Issue 8, August 2026.
Cementum attachment protein‐derived peptides adsorb to specific crystallographic faces of brushite and calcium oxalate, blocking calcium deposition. This phosphorylation‐enhanced modulation alters crystal growth under conditions in vitro, leading to the formation of irregular brushite crystals and rosette‐like calcium oxalate morphologies.

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.

Does the Combination of Abdominal Obesity and Vitamin D Deficiency Increase the Risk of Death in Individuals Aged 50 or Older? Evidence From the ELSA Study

Diabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 6607-6617, August 2026.
ABSTRACT Aims Despite the known association between abdominal obesity (AO) and vitamin D deficiency, it remains unclear whether this combination is associated with higher mortality risk. We investigated whether the coexistence of AO and vitamin D deficiency elevates the risk of death.
