🧬 When immunity saves—and harms—at the same time
A striking NEJM correspondence reveals that patients receiving immune checkpoint inhibitors often sustain molecularly detectable multiorgan damage—weeks to months before symptoms appear. Using cell-free DNA methylation mapping, investigators show that immune-related adverse events are systemic, not isolated organ toxicities—the visible clinic finding is just the tip of the iceberg 🧊🧬
This work reframes irAEs as a global loss of immune tolerance and opens the door to early, molecular surveillance—particularly relevant for cardio-oncology and precision medicine.
