Article Abstract

This study investigates the role of c-FLIP in sepsis-induced myocardial dysfunction (SIMD), focusing on cardiac microcirculation and mitochondrial autophagy. Using SIMD rat and LPS-induced cardiac microvascular endothelial cell injury models, we found that c-FLIP deficiency disrupts mitochondrial homeostasis, exacerbating microcirculatory damage. c-FLIP differentially regulates mitochondrial autophagy via FUNDC1. Overexpression of c-FLIP balances autophagy, protects mitochondria, reduces inflammation, and ameliorates SIMD, highlighting its potential as a therapeutic target.

We explored the role of Polygonatum Rhizoma polysaccharide (PRP) in delaying aging and improving Alzheimer's disease (AD) and revealed its potential molecular mechanism. Through chemical characterizations to clarify the physicochemical properties of PRP, it was found that PRP mainly consists of mannose, glucose, galactose, and arabinose, with molecular weights ranging from 7.4 × 10 to 9.

Tire wear particles (TWP) represent a significant source of marine microplastic pollution and have been shown to pose a considerable threat to marine organisms. In this study, the marine rotifer Brachionus plicatilis was employed as a model organism to systematically assess the effects of micron-sized and nano-sized TWP, as well as their leachates, on rotifer behavior, and underlying molecular mechanisms. The results revealed that TWP exposure significantly reduced rotifer motility, evidenced by decreased swimming speed and acceleration.

The dynamic monitoring of cell death processes remains a significant challenge due to the scarcity of highly sensitive molecular tools. In this study, two hemicyanine-based probes (5a-5b) with D-π-A structures were developed for organelle-specific viscosity monitoring. Both probes exhibited correlation with the Förster-Hoffmann viscosity-dependent relationship (R > 0.

Immune checkpoint inhibitors (ICIs) can re-active the immune response and induce a complete response in mismatch repair-deficient and microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC). However, most CRCs exhibit proficient mismatch repair and microsatellite stable (pMMR/MSS) phenotypes with limited immunotherapy response because of sparse intratumoral CD8 T-lymphocyte infiltration. Cellular senescence has been reported to involve immune cell infiltration through a senescence-associated secretory phenotype (SASP).
