Stem cells with ‘dual identity’ linked to loss of smell from sinus inflammation

In experiments with mice and human tissue samples, Johns Hopkins Medicine researchers report evidence that neuronal stem cells in the part of the nose responsible for the sense of smell transform themselves to perpetuate the long-term inflammation in chronic sinusitis. Results of the study, they say, suggest that the stem cells’ ability to switch their identity to join in the […]

Identity crisis of satiety neurons leads to obesity

Obesity − as research in the past decade has shown − is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal Nature Metabolism. The worldwide epidemic […]
