A T cell, here in purple, makes contact with a transplant organ cell, here in reddish brown. 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 pink. The signal molecules make their way into the urine, where they give off a fluorescent cue. Georgia Tech / EllaMaru Studio (work for hire, all rights GT, free for distribution).

'Demolition Handshakes' Kill Precursor T Cells that Pose Autoimmune Dangers

Atlanta, GA

A mechanism tries to stop our T cells from causing autoimmune disorders, and it's like a tight handshake that kills overly aggressive T cells.

3D-Printed Tracheal Splints Used in Groundbreaking Pediatric Surgery

Atlanta, GA

With support from Georgia Tech, Children's Healthcare of Atlanta placed 3D-printed tracheal splints in a pediatric patient.

An illustration of improved delivery of anti-cancer drugs to malignancies in the brain. On the left half, focused ultrasound agitates microbubbles, which breach the blood-brain barrier, allowing drug molecules to get through. The forces also stir interstitial fluid to circulate the drug, and they also encourage the drug to cross cell membranes more easily into tumor cells.
