Pyroptosis in Endothelial Cells and Extracellular Vesicle Release in Atherosclerosis via NF-κB-Caspase-4/5-GSDM-D Pathway.

: Pyroptosis, an inflammatory cell death, is involved in the progression of atherosclerosis. Pyroptosis in endothelial cells (ECs) and its underlying mechanisms in atherosclerosis are poorly understood. Here, we investigated the role of a caspase-4/5-NF-κB pathway in pyroptosis in palmitic acid (PA)-stimulated ECs and EVs as players in pyroptosis.

Interplay between Antimicrobial Peptides and Amyloid Proteins in Host Defense and Disease Modulation.

The biological properties of antimicrobial peptides (AMPs) and amyloid proteins and their cross-talks have gained increasing attention due to their potential implications in both host defense mechanisms and amyloid-related diseases. However, complex interactions, molecular mechanisms, and physiological applications are not fully understood. The interplay between antimicrobial peptides and amyloid proteins is crucial for uncovering new insights into immune defense and disease mechanisms, bridging critical gaps in understanding infectious and neurodegenerative diseases.

Chlorpyrifos and dimethoate exposure impairs female fertility by deregulating WNT signaling pathway & uterine receptivity.

The study assessed histological, biochemical, oxidative stress, and molecular parameters to evaluate the consequences of Chlorpyrifos and Dimethoate exposure on uterine health in female rats. Despite showing no obvious signs of toxicity apart from minor clinical symptoms in DM-exposed rats, both pesticides caused degenerative changes in uterine tissue. This study demonstrates that pesticides induce inflammatory responses and oxidative stress in rats, by NF-κB activation and altering antioxidant enzyme levels.
