Scientists Become Filmmakers To Decipher Immunity
For years, scientists studying the immune system have based their observations on snapshots of isolated cells and tissues. Now, thanks to emerging technologies, researchers can have front-row seats to the dance of immune cells occurring within living tissues. New research, reported in three papers in the June 7 issue of the journal Science, for the first time visualizes the behavior of immune cells and their targets in intact lymph nodes. The publications open the door to important new discoveries that were not possible using previous techniques.
