A team of researchers has revealed the molecular mechanisms underlying the binding of small extracellular vesicles to host cells, which could lead to the development of more effective cancer treatments. The study found that EVs primarily bind to laminin via CD151-associated integrin heterodimers and GM1, eliciting responses in recipien...
Researchers identified unique biological mechanisms that cause premature aging in the brains of individuals with alcohol, opioid, and stimulant use disorders. Different substances appear to hijack the brain's natural aging rhythm through distinct molecular mechanisms, though some pathways are shared across different substance types.
Researchers discovered a new process by which cancer cells use small extracellular vesicles to spread to healthy tissue. The study found that these vesicles are primarily internalized by clathrin-independent endocytosis via galectin-3, which is facilitated by an increase in intracellular calcium concentration.
Developing neurons rely on multiple signaling pathways to migrate from the germinal zone. An antagonistic circuit between Netrin-1 'pushing' and Siah2 'pulling' ensures proper cerebellum development by balancing adhesion and guidance cues.
Researchers found that low Wnt signaling levels regulate NPC self-renewal, while higher levels initiate differentiation into mature kidney cell types. The studies also reveal the role of beta-catenin in aggregating NPCs to form early kidney structures.
Researchers have discovered that intestinal bacteria can lead to more severe adhesions after abdominal surgery. The study found that mesothelial cells and EGFR signaling play a crucial role in the formation of these adhesions. The findings suggest that targeting EGFR may be a potential approach to reducing adhesion risk.
Researchers from Rice University and the University of Wyoming discovered self-organization into circular aggregates in Myxococcus xanthus, a model system for social cooperation. The circular behavior is linked to TraAB protein overexpression, which creates a sticky bond between cells, preventing reversals.
Researchers discovered that actin filaments serve as tiny stretchy tension sensors in cells, transmitting mechanical signals to other proteins. The findings have significant implications for understanding how cells mechanically control movement, including cardiac cell contraction and motile cell migration.
Researchers at Rensselaer Polytechnic Institute have identified a crucial signaling pathway involved in tissue growth and wound healing. The discovery provides new insights into how cells interact during tissue remodeling and may lead to novel therapeutics for diseases such as cancer and arthritis.
