Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Dll4 signalling through Notchi regulates formation of tip cells during angiogenesis

All tissues, sick and healthy alike, need a blood supply to survive and grow. The key to many medical problems, like preventing tumour development, is therefore to obstruct the spread of the blood vessels. Research scientists at Karolinska Institutet have now discovered a heretofore unknown mechanism for how the body links together its blood vessels.
