Technology from the Zhu lab: A cell chamber is mounted on a microscope. Three micropipettes, inserted into the chamber from both sides, are used to aspirate individual cells, to bring them into contact so that researchers can study their interactions. This is the kind of methodology that Cheng Zhu and his colleagues used to study PD-1, which might be the most famous molecule in the world. 
Zhu Lab Explains the Inhibitory Role of World’s Most Famous Molecule

New research teases apart the mechanisms behind the checkpoint protein PD-1
The activity sensor illustrated in reddish-pink with small, green attachments is shown here in its application to detect organ transplant rejection. T cells secrete the enzyme granzyme, here in gray, which kills cells but also severs the fluorescent green signal molecules from the activity sensing nanoparticle. The green signal molecules make their way into the urine, where they give off a fluorescent cue. Credit: Georgia Tech / EllaMaru Studios work for hire / press handout
Urine Test to Evaluate Immunotherapy Success Gets $1.8 Million NIH Research Grant

Immunotherapy can eradicate cancer or fall down trying, and this sensor monitors that success or failure.

Remote-Control Shoots Laser at Nano-Gold to Turn on Cancer-Killing Immune Cells

A near-infrared light, similar to that of a TV remote, combines with gold nano-particles to flip a gene switch in T-cells to hyper-activate them inside of tumors.
