Landscape Immunology - High dimensional spatial proteomics

The immune system integrates information across multiple scales to develop an effective response to invading pathogens and to regulate tissue specific immunity. Modern approaches in high dimensional proteome microscopy are key to understanding the complexities of this spatial regulation. We use multimodal imaging approaches by combining microscopy with mass spectrometry to analyse the local regulation of immune responses. An interdisciplinary analysis combines immunohistochemistry (IHC), matrix-assisted laser desorption/ ionization imaging mass spectrometry (MALDI IMS) and liquid chromatography with tandem mass spectrometry (LC-MS/MS) to unravel novel mechanisms that spatially regulate tissue specific immunity by a systems medicine approach.

Crosstalk of tissue macrophages and neutrophils 

Neutrophils are continuously generated within the bone marrow and released in the circulation. They rapidly migrate into infected tissues and significantly contribute to the inflammatory and antimicrobial process. However, the mechanisms that regulate the interstitial migration and the function of neutrophils in infected organs are incompletely understood. We use state of the imaging techniques to analyse the role of tissue macrophages, which form a dense network of sentinel cells within tissues, in regulating neutrophil migration and function in inflamed tissues.
