Pathology from the Molecular Scale on Up.

Recorded On: 02/07/2018

High parameter single cell analysis has driven deep understanding of immune processes.  Using a next-generation single-cell “mass cytometry” platform we quantify surface and cytokine or drug responsive indices of kinase target with 45 or more parameter analyses (e.g. 45 antibodies, viability, nucleic acid content, and relative cell size).  Similarly, we have developed two advanced technologies that enable deep phenotyping of solid tissue in both fresh frozen and FFPE formats (50 – 100 markers).   I will present evidence of deep internal order in immune functionality demonstrating that differentiation and immune activities have evolved with a definable “shape”.  Further, specific cellular neighborhoods of immune cells are now definable with unique abilities to affect cellular phenotypes—and these neighborhoods alter in various disease states.   These shapes and neighborhoods are altered during immune surveillance and “imprinted” during, and after, pathogen attack, traumatic injury, or auto-immune disease.  Hierarchies of functionally defined trans-cellular modules are observed that can be used for mechanistic and clinical insights in cancer and immune therapies.
