to study its effects on microbial adhesion-triggered endocytosis (MATE) vesicle morphology in segmented filamentous bacteria (SFB)-colonized mice[3]

CASIN is an inhibitor of Cdc42 GTPase, a small GTPase of the Rho-subfamily that plays important roles in cytoskeleton organization, cell cycle progression, signal transduction, and vesicle trafficking. CASIN generated a rejuvenated phenotype of Hematopoietic stem cells (HSCs), reversing the aging-related and polarity phenotype of aged HSCs to that of young HSCsin vivo..

Extracellular vesicles (EVs) derived from the gut microbiota are largely uncharacterized and their impacts on host intestinal physiology remain unresolved. Here, we isolated EVs from F. nucleatum for detailed characterization. Our analyses highlight the presence of the outer membrane protein

Cadmium (Cd) is a toxic heavy metal that impairs the development of hematopoietic stem cells (HSCs) in mice, yet the mechanism of how Cd influences HSC remains elusive. Herein, we show that Cd activated non-canonical Wnt signaling pathway to impair
Commensal bacteria influence host physiology, without invading host tissues. We show that proteins from segmented filamentous bacteria (SFB) are transferred into intestinal epithelial cells (IECs) through adhesion-directed endocytosis that is distinct from the clathrin-dependent endocytosis of invasive pathogens. This process
Throughout a 24-h period, the small intestine (SI) is exposed to diurnally varying food- and microbiome-derived antigenic burdens but maintains a strict immune homeostasis, which when perturbed in genetically susceptible individuals, may lead to Crohn disease. Herein, we demonstrate that
