Tuft cells (in green) in the lung tissue of a mouse
Andrew Vaughan/University of Pennsylvania
Researchers have successfully labeled individual sensory cells that can detect foreign organisms and irritating chemicals. The cells developed in the lungs of mice after a severe case of flu, they reported on March 25 in the American Journal of Physiology-Lung Cellular and Molecular Physiology.
These so-called tuft cells resemble taste bud cells and are not originally found in the lungs. They can be found in the trachea, but the researchers suggest that the presence of tuft cells in the lungs may contribute to persistent inflammation.
