About the Project

Our research aims to elucidate the molecular and cellular regulation of innate immune signal transduction in the context of infectious, inflammatory and autoimmune disease. We focus on the Toll-like receptors that respond to pathogen associated molecules such as lipopolysaccharide and non-self nucleic acids. A second strand of our research is the functional and evolutionary inter-relationships in the ontogeny of the nervous and immune systems. We focus on the function of Toll receptors in invertebrate neurogenesis and the role of signaling by Toll-like receptors (TLRs) and LRRK2 in vertebrate microglia for the initiation and progression of neurodegenerative diseases, especially Parkinson’s. We published high impact papers showing that in Drosophila Toll receptors fulfill the function of neurotrophins in the insect nervous system. Our future research aims are to use cutting edge techniques in single molecule imaging of live cells, biophysics, structural and cell biology to elucidate the kinetics, dynamics and cooperativity of inflammatory signaling.
