Genetically Engineered Mouse Model Reveals Key to Formation of the Blood-Brain Barrier

Use of a mouse model that had been genetically engineered to lack the gene that encodes the forkhead transcription factor Foxf2 has helped to explain how pericytes, cells that line the capillaries, form and maintain the blood-brain barrier.  More...

Cholesterol Trafficking in the Mouse Embryo Is Regulated by a snoRNA

Cellular cholesterol trafficking in mouse embryos was found to be regulated by U17 snoRNA.   More...

Extracellular Protein Kinase Interacts with Broad Spectrum of Potential Substrates

A single enzyme, Fam20C, has been linked to the phosphorylation of more than 100 different proteins representing nearly 90% of all phosphorylated secreted proteins.  More...

Regulatory T-cells (Treg cells) are critically important for preventing the body’s immune response from going overboard and causing autoimmune disease (Photo courtesy of the [US] National Institute of Allergy and Infectious Diseases).

Hypoxia Factors Contribute to Maintenance of Regulatory T-cell Function

A team of cell biologists has identified a molecular pathway that maintains the stability and function of regulatory T-cells, which are components of the immune system that suppress immune responses of other cells and act as an important “self-check” built into the immune system to prevent excessive reactions.  More...

Real-Time Studies Show How an Effector Protein Regulates Cellular Gene Expression

A series of elegant single molecule experiments have revealed in real-time how the effector protein HP1alpha interacts with chromatin in its target histones to regulate gene expression.  More...

Suppression of DNA Repair by H. pylori Paves the Way for Development of Gastric Cancer

A team of molecular microbiologists has established what they believe to be the definitive link between Helicobacter pylori infection and the development of gastric cancer.  More...
