Nanoparticle Engineered at Georgia Tech May Replace Biopsy Needles in Detecting Transplant Organ Rej (IMAGE)
Caption
A T cell, here in violet, makes contact with a transplant organ cell, here in dark red. The T cell secretes the enzyme granzyme B, here in gray, which attacks the organ cell. But granzyme B also severs fluorescent signal molecules, in green, from the rejection detecting nanoparticle, in light red. The signal molecules makes their way into the urine, where they give off a fluorescent cue.
