Smoking May Spark Reaction Tied to Dementia
A University of Chicago team discovered that nicotine triggers a previously unknown lung‑brain signaling pathway. Pulmonary neuroendocrine cells (PNECs) release exosomes packed with serotransferrin, which upset iron regulation in neurons and spark oxidative damage linked to dementia. The researchers created induced PNECs from stem cells to capture this response, providing the first mechanistic bridge between smoking and neurodegeneration. The work suggests that interrupting exosome signaling could become a novel therapeutic avenue.
