Identifying a role
for tuft cells in the interactions between the virus and its host «is a significant step forward,» says immunologist David Artis of Weill Cornell Medicine in New York City, who was not involved in the study.

Having more
tuft cells seems to be «good
for the virus,» Wilen says.
It thus finally became possible
for the scientists to observe and measure the activity of the
tufted cells under the microscope.
The answer to this question has been slow in coming, as the
tufted cells are extremely small — much too small
for sticking an electrode into them and capturing their electrical signals.
For instance, the team uncovered a new type of chemical - sensing
tuft cell (which helps alert the immune system to infection or other forms of injury) that displayed markers previously thought to be exclusive to immune
cells and which may help sound the alarm about allergens and invading parasites.
