A single-cell atlas of pig gastrulation as a resource for comparative embryology
Cell-fate decisions during mammalian gastrulation are poorly understood outside of rodent embryos. The embryonic disc of pig embryos mirrors humans, making them a useful proxy for studying gastrulation. This study presents a single-cell transcriptomic atlas of pig gastrulation, providing valuable insights into this critical developmental stage. By leveraging advanced technology and cutting-edge methodologies, researchers have been able to map gene expression profiles at a single-cell resolution, allowing for a comprehensive examination of the cellular dynamics during gastrulation. Through this resource, researchers can expand their understanding of gastrulation processes and compare them across species, shedding light on evolutionary relationships and developmental mechanisms.
Conformational analysis and interaction of the Staphylococcus aureus transmembrane peptidase AgrB with its AgrD propeptide substrate
Virulence gene expression in the human pathogen, S. aureus, is governed by the agr (accessory gene regulator) quorum sensing system, which is conserved in diverse Gram-positive bacteria. This study delves into the conformational analysis and interaction of the Staphylococcus aureus transmembrane peptidase AgrB with its AgrD propeptide substrate. Understanding the molecular mechanisms underlying virulence gene regulation in S. aureus is crucial for developing targeted therapeutic interventions. By elucidating the structural basis of AgrB-AgrD interactions, researchers can gain insights into the virulence control pathways and potentially identify novel drug targets for combating S. aureus infections.
