Hyperuricemia and crystal-induced nephropathies
Final Report Abstract
Due to the mutually reinforcing results and the large number of published work, the topic of soluble and crystalline uric acid (asymptomatic and symptomatic hyperuricemia) on the effector functions of immune cells including macrophages, neutrophils and monocytes in kidney disease could be further developed in the context of sterile inflammation. These findings are of translational importance and provided evidence for previously unexplained clinical observations, e.g. in gouty arthritis. The applicant has set up new collaborations, has been asked to present on this topic at meetings and congresses, and has become an independent group leader. The novel implications and research findings will be now extended beyond this subject, for example the applicant received DFG funding to investigate the antioxidative and immunoregulatory function of soluble uric acid in CKD with emphasize on infections (secondary immunodeficiency related to kidney disease) as well as is involved in one sub-project as project leader in the DFG Transregioinitiative on neutrophils to identify mechanisms that are associated with soluble metabolites and neutrophil functions during crystal-induced kidney injury.
