In the fragile hours after a heart attack, the body's own defense mechanisms can become a second wound — a surge of immune cells, summoned by ancient stress signals, that overwhelms the very tissue it means to protect. Researchers at the University of Oklahoma have traced this inflammatory flood to its unexpected source: neutrophils already stationed along blood vessel walls, released in a rush by stress hormones before the bone marrow ever stirs. Their findings, published in Nature Communications, suggest that briefly quieting these stress signals with existing drugs may help the heart heal n
