Peptide-Purified Anti-N-methyl-D-aspartate Receptor (NMDAR) Autoantibodies Have Inhibitory Effect on Long-Term Synaptic Plasticity.

Recent studies, typically using patient cerebrospinal fluid (CSF), have suggested that different autoantibodies (Aabs) acting on their respective receptors, may underlie neuropsychiatric disorders. The GluN1 (NR1) subunit of the N-methyl-D-aspartate receptor (NMDAR) has been identified as a target of anti-NMDAR Aabs in a number of central nervous system (CNS) diseases, including encephalitis and autoimmune epilepsy. However, the role or the nature of Aabs responsible for effects on neuronal excitability and synaptic plasticity is yet to be established fully.

Valorizing sardine scales: a circular approach to sustainable collagen for cosmetics and nutrition applications.

Background And Objective: In recent years, the consumption of fish products has led to a worrying trend where approximately two-thirds of the total amount of fish is discarded as waste. At the same time, scientific interest in exploring natural collagen sources for cosmetics and dietary supplements has increased. This study explores the potential of valorizing sardine scales (), a by-product of the canning industry, through the extraction of collagen for potential use in dermocosmetic formulations and food supplements.

Glycolytic activity following anti-CD19 CAR-T cell infusion in non-Hodgkin lymphoma.

Energy metabolism of chimeric antigen receptor-T cells (CAR-T) activation in humans remains unexplored. As a glycolytic activity surrogate, we investigated the dynamics of peripheral blood (PB) lactate in the first weeks post-CAR-T infusion. In 17 patients treated with CD28 harbording anti-CD19 CAR-T for relapsed/refractory non-Hodgkin lymphomas, PB lactate levels increased following CAR-T infusion.

Nanoparticles use magnetoelectricity to target and eradicate cancer cells.

Unlabelled: This study presents the first in vivo and in vitro evidence of an externally controlled, predictive, MRI-based nanotheranostic agent capable of cancer cell specific targeting and killing via irreversible electroporation (IRE) in solid tumors. The rectangular-prism-shaped magnetoelectric nanoparticle is a smart nanoparticle that produces a local electric field in response to an externally applied magnetic field. When externally activated, MENPs are preferentially attracted to the highly conductive cancer cell membranes, which occurs in cancer cells because of dysregulated ion flux across their membranes.
