This study investigates how ZBP1-driven macrophage pyroptosis worsens sepsis-induced acute lung injury by damaging the pulmonary epithelium. Through single-cell RNA sequencing of human and mouse samples, researchers identified a specific group of pyroptosis-associated macrophages that expands during severe sepsis. These macrophages interact with the NLRP3 inflammasome to trigger cell death and rel...

This research examines how the protein Nrf2 protects different types of brain cells during an acute ischemic stroke . By using specialized mouse models, the authors discovered that Nrf2 performs unique, cell-specific roles to prevent brain damage. In neurons , this protein primarily functions to block ferroptosis , a specific form of iron-dependent cell death. Conversely, in astrocytes , it works...

This research identifies a novel biochemical mechanism where S-palmitoylation regulates the stability of the GLI1 protein, a key driver in Sonic Hedgehog medulloblastoma (MBSHH) .

Conversely, the enzyme ABHD17A acts as a deacylase that removes this m...

This study identifies CD23 as a critical internal regulator that maintains the balance of NKT17 cells by protecting their survival. Researchers discovered that a lack of CD23 selectively reduces the number of these specific immune cells and decreases their IL-17 production , which in turn lowers airway inflammation in asthmatic models. Mechanistically, CD23 supports the IL-7Rα-mTORC2-AKT signaling...
