Immune cells may heal an injured heart

Researchers at the School of Medicine have shown that two major pools of immune cells are at work in the heart. Both belong to a class of cells known as macrophages. One appears to promote healing, while the other likely drives inflammation, which is detrimental to long-term heart function.

Scientists identify clue to regrowing nerve cells

School of Medicine researchers have identified a chain reaction that triggers the regrowth of some damaged nerve cell branches, a discovery that one day may help improve treatments for nerve injuries that can cause loss of sensation or paralysis. To study how nerve cells respond to injuries in their branches, researcher Valeria Cavalli grows them in “spots,” like the one pictured.
