Injection site fibroblasts acquire antigen-presenting cell properties and modulate mRNA-LNP immune responses

This study reveals that mRNA-LNP vaccines induce tissue-resident fibroblasts at the injection site to acquire antigen-presenting cell properties, demonstrating that LNP composition directly shapes stromal cell function to modulate global immune responses.

Proteomic and Machine Learning Analyses Reveal the Mechanism of Baicalin in Inhibiting Biofilm Formation of Escherichia coli

This study demonstrates that baicalin inhibits *Escherichia coli* biofilm formation not by reducing bacterial viability, but by disrupting energy metabolism and redox balance to impair flagellar assembly and motility, thereby blocking early adhesion processes.

Exploratory cross-cohort assessment of a post-hoc FAP-associated epithelial transcriptomic module in colorectal datasets

This study evaluates a post-hoc 36-gene epithelial module (M02) derived from FAP single-nucleus data, finding that while it shows consistent positive associations in independent FAP donors and some bulk datasets, it remains a selection-conditioned candidate rather than an independently validated sporadic-adenoma signature due to inherent design-time bias and limited external patient-level evidence.

Transcriptomic Remodeling of the Hypothalamic Paraventricular Nucleus in Pregnant Spontaneously Hypertensive Rats: Autonomic Dysfunction and Neuroimmune Signature

This study reveals that pre-existing chronic hypertension in pregnant rats transforms the hypothalamic paraventricular nucleus's response from a subtle homeostatic adjustment into a massive transcriptomic reprogramming event, characterized by neuroimmune activation and autonomic dysfunction, which serves as an active counter-regulatory mechanism to sustain pregnancy despite elevated cardiovascular risk.

First record of severe hypopigmentation in a tiger shark Galeocerdo cuvier from the southwestern Atlantic Ocean

This study documents the first record of severe hypopigmentation, likely leucism, in a tiger shark (*Galeocerdo cuvier*) captured in the southwestern Atlantic Ocean, highlighting the value of fishery-dependent observations for identifying rare phenotypic traits in marine megafauna.

Crown snow amplifies snowpack-driven bending stress through trunk form change in snow-buried subcanopy and understory woody plants: a structural-mechanical model for Fagus crenata in a heavy snow forest

This study presents a structural-mechanical model demonstrating that while crown snow does not directly cause significant stress in buried *Fagus crenata* trunks, it amplifies snowpack-driven bending stress by altering trunk form through a hysteresis effect, thereby increasing the risk of snow damage under future wet-snow conditions.

Alternate-conformer incompatibility as the dominant bottleneck in no-repair receptor preparation: a frozen compatibility audit of 30 public PDB structures

This study demonstrates that a fully automated, no-repair receptor preparation protocol fails for 70% of high-resolution PDB structures primarily due to unresolved alternate conformers, revealing that such structural ambiguities constitute the dominant bottleneck in generating compatible receptors for reference-pose docking studies.
