Danish researchers expose new cause of life-threatening disease
Date:6/7/2013

Danish researchers have just published findings that explain a previously unknown mechanism used by cells to communicate with one another. The research significantly contributes to understanding why some children are born with malformations and why children and adults may develop life-threatening diseases.

Dr. Sren Tvorup Christensen (Department of Biology) and Professor Lars Allan Larsen (Department of Cellular and Molecular Medicine) at the University of Copenhagen, in collaboration with colleagues in Denmark and France, have spearheaded the recent discovery which sheds new light on the causes of a range of debilitating diseases and birth defects.

Antennae-like structures on the surface of cells

Over the years, the research group has been a leader in primary cilium research. Primary cilia are antennae-like structures found on the surface of nearly all cells in the human body. These antennae are designed to receive signals, such as growth factor and hormones, from other cells in the body and then convert these signals to a response within individual cells. Defective formation or function of these antennae can give rise to a range of serious maladies including heart defects, polycystic kidney disease, blindness, cancer, obesity and diabetes. However, there remains a great deal of mystery as to how these antennae capture and convert signals within cells.

The groundbreaking results have been published in Cell Reports, a prestigious scientific journal. The research is supported by the Lundbeck Foundation, the Novo Nordisk Foundation and the Danish Heart Association (in Danish), among others.

"We have identified an entirely new way by which these antennae are able to register signals in their midst, signals that serve to determine how cells divide and move amongst one another. This also serves to explain how a stem cell can develop into heart muscle," explains Sren Tvorup Christensen.
