MADISON, Wis. - An uncommon and little-studied type of cell in the lungs has been found to act like a sensor, linking the pulmonary and central nervous systems to regulate immune response in reaction to environmental cues.
The cells, known as pulmonary neuroendocrine cells or PNECs, are implicated in a wide range of human lung diseases, including asthma, pulmonary hypertension, cystic fibrosis and sudden infant death syndrome, among others.
