Nanotechnology and single cell proteomics as a diagnostic tool

Abstract

Single-cell functional proteomics assays can connect genomic information to biological function through the use of quantitative and multiplex protein measurements. Tools for single-cell proteomics have developed rapidly over the past 5 years, and are providing approaches for directly elucidating phospho-protein signaling networks in cancer cells, or for capturing high-resolution snapshots of immune system function in cancer patients participating therapies that involve immune system engineering and manipulation. We discuss advances in single cell proteomics platforms, with an emphasis the types of data that can be obtained, and how analysis of that data can provide deep insights into either designing therapies, or understanding patient responses to therapies. I will provide illustrative examples of how microchip-based single cell functional proteomics platforms are being applied to both fundamental biology and clinical studies.
