Researchers used live fluorescence imaging experiments to uncover the mechanism behind cell volume regulation, revealing that WNK kinases activate the 'switch' through phase separation. This discovery has implications for human health, particularly in relation to kidney function and salt-sensitive hypertension.
The study assesses how temperature influences droplet size in elastic matrices, providing insights into biological molecule arrangement and condensate formation. It also explores the role of phase separation and its effect on droplet growth.
Divita Mathur is investigating cytosolic access and instability of DNA nanoparticles to overcome current delivery mechanisms. The goal is to create more biocompatible delivery systems, enabling advanced targeted therapies.
Researchers have unraveled the mechanisms of how cells capture and degrade fluid droplets through autophagy. The study reveals that a tug-of-war between the droplet's surface tension and the isolation membrane's bending energy governs this process, with the outcome determining whether a piece or complete droplet is captured.
Researchers identified a crown-shaped molecular pore in coronavirus replication compartments that may facilitate viral RNA export. This discovery offers a potential target for antiviral strategies against SARS-CoV-2 and other coronaviruses.
Researchers at Ludwig-Maximilians-Universität München identified a signaling pathway enabling mitochondria to transmit distress signals to the surrounding cytosol. This pathway involves enzymes OMA1 and DELE1, which trigger cellular responses to stress, potentially opening new therapeutic approaches for age-related diseases.
A study published in The Plant Journal has provided new insights into the dynamics of metabolic processes in eukaryotic cells. By quantifying the subcellular distribution of proteins and metabolites, researchers have identified key regulatory mechanisms controlling plant metabolism.
Researchers at ETH Zurich have developed a new method for extracting the content of single living cells, enabling scientists to study individual cells at the molecular level. The technique allows for precise extraction of intracellular material, preserving live cells for repeated sampling and analysis.
The International Classification of Functioning, Disability and Health (ICF) provides a scientific basis for understanding health and disability states. ICF has become a valuable tool to increase communication among different users in clinical practice and research.
A new theoretical model shows that the length of microtubules is regulated by the attachment of motor proteins, which grow towards the plus-end and shorten the filament. This interplay between growth and shrinkage maintains a precisely regulated microtubule length essential for various intracellular tasks.
The DALYs system, widely used to measure public health interventions' effects, fails to account for the complexities of disability. Critics argue that this approach undervalues the lives of disabled individuals, instead prioritizing those without disabilities.
A study found a higher prevalence of the D variant in the ACE gene among Gulf War veterans with chronic fatigue syndrome. Veterans with specific genetic variants were more likely to develop CFS/ICF, suggesting an interaction between genetics and environmental factors related to deployment.
Researchers found that bacterial proteins are destroyed by the proteasome within the cytosol during infection, activating the immune system. Bacteria like Listeria avoid recognition by moving within the cytosol, preventing immune activation.
A new theory explains how prion diseases get started and kill neurons by showing that small amounts of misfolded PrP in the cytosol can cause cell death. The research also reveals a mechanism for the conversion of normal PrP to its toxic form, which can then spread and aggregate.
