Role of S100A8/A9 dimers and tetramers in the regulation of neutrophil dynamics in chronic inflammation (C07)

• Subject Area: Immunology
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 449437943

The aim of the present proposal is to understand how neutrophils are controlled to prevent un-wanted immune system activation. We hypothesize that S100A8/A9 with its two occurring quaternary structures dimer versus tetramer differentially modulate neutrophils, with tetramers keeping them in a silent but alert mode upon dimer activation, thereby locally confining neutrophil activity. A better understanding of these regulatory mechanisms and how they can be tuned will pave the way towards novel therapeutic interventions in chronic inflammatory neutrophil-driven diseases.
