Inducing Right Ventricular-Like Cardiomyocytes
2026-08-11
Saito and colleagues developed a modified GiWi differentiation strategy that shifts human pluripotent stem cell cardiac progenitors from a first heart field-like toward an anterior second heart field-like identity. The resulting right ventricular-like cardiomyocytes displayed distinct gene expression and functional phenotypes, providing a more appropriate cellular model for right-sided cardiac disease research.

Spiroplasma Entry into Drosophila S2 Cells
2026-08-11
Wei and colleagues established a Drosophila Schneider 2 cell model showing that Spiroplasma eriocheiris invades insect cells through clathrin-mediated endocytosis and macropinocytosis, with contributions from actin filaments and microtubules. The study provides a practical pharmacological framework for separating bacterial entry, intracellular proliferation, and host-cell injury while highlighting the limits of extrapolating results from insect cells to crustacean infection.

Enzyme-Induced Hypoxia and Urothelial Inflammation
2026-08-10
Hudson and colleagues show that hypoxia duration determines whether rat urothelial cells develop a caspase-1-associated inflammatory response. Brief enzyme-induced hypoxia stabilized HIF-1α without detectable inflammasome activation, whereas prolonged exposure increased caspase-1 through a pathway attenuated by glutathione and verapamil, implicating ROS/TXNIP/NLRP3 signaling.
