Ziprasidone Augmentation in Anxious Depression
2026-09-01
This post-hoc moderator analysis examined whether anxious depression altered the antidepressant or anxiolytic response to ziprasidone augmentation of escitalopram. The treatment showed comparable improvement in depressive symptoms across subgroups, while the apparent anxiety benefit in patients with greater baseline anxiety was not clinically meaningful.

How NAC Coordinates Nascent Protein Processing
2026-09-01
Lentzsch et al. show that the nascent polypeptide-associated complex (NAC) organizes MetAP1 and NatA/E on translating ribosomes, enabling timely sequential processing of emerging protein N termini. By combining FRET, cryo-electron microscopy, biochemical assays, and cellular or organismal experiments, the study provides a mechanistic explanation for how cotranslational methionine excision and acetylation are coordinated.

Angiotensin Peptides and SARS-CoV-2 Spike Binding
2026-08-29
Oliveira and colleagues reported that naturally occurring angiotensin peptides can increase SARS-CoV-2 spike-protein binding to host receptors, with the strongest effects associated with selected shorter and N-terminally truncated fragments. The study provides a biochemical rationale for examining renin–angiotensin signaling pathway peptides in viral-receptor research while emphasizing that binding enhancement is not equivalent to demonstrated infection or clinical risk.

Cationic Lipids Shape mRNA-LNP Immunogenicity
2026-08-28
The reference study shows that adding classical cationic lipid to mRNA-LNPs can tune innate immune activation and antitumor efficacy, but the outcome depends strongly on the ionizable lipid backbone. Its comparative design offers a practical framework for balancing dendritic-cell activation, antigen expression, and durable humoral and cellular immunity.

Angiotensin III: A Translational RAAS Probe
2026-08-25
Angiotensin III is more than a downstream RAAS fragment: it is an experimentally useful probe of aldosterone regulation, pressor signaling, AT1 and AT2 receptor biology, and emerging angiotensin-peptide effects on SARS-CoV-2 spike-protein binding. This article translates its mechanistic profile into practical guidance for cardiovascular, neuroendocrine, and exploratory translational research.

Troxerutin, TRPM7, and Diabetic Cognitive Dysfunction
2026-08-24
A 2025 study identifies the TRPM7/calcineurin/Drp1Ser637 axis as a mechanistic link between calcium dysregulation, mitochondrial fission, neuronal apoptosis, and diabetic cognitive dysfunction. Using db/db mice and high-glucose-treated hippocampal neurons, the authors show that troxerutin improves cognitive and mitochondrial outcomes by suppressing this pathway.
