immune system

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.

Understanding the biophysical cues provided by pathogenic particles may help vaccine developers fine tune the signals they already knew were being transmitted by the molecular information presented to the immune system. The research could provide a new tool for vaccine developers, said Krishnendu Roy, the Robert A. Milton Chair and professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. (Credit: Rob Felt, Georgia Tech)
