New insights on stem cell clones and inflammation in the bones

Research led by George Hajishengallis of Penn Dental sheds light on an aging-related condition that drives inflammation in older populations.

Collaborative study, led by George Hajishengalis of the School of Dental Medicine, highlights key insights into clonal hematopoiesis of indeterminate potential (CHIP), an aging-related condition that raises the risk for several inflammatory diseases. The research also indicates that the FDA-approved drug rapamycin could reverse these adverse effects and treat inflammatory bone loss.
