IMMEI study identifies cellular and molecular mechanisms promoting severe ANCA vasculitis progression

A study led by the teams of Natalio Garbi and Christian Kurts at the IMMEI identifies cGAS/STING activation and IFN-I production by inflammatory macrophages as a driver of severe ANCA-associated autoimmune vasculitis. Genetic and pharmacological interventions blocking this pathway ameliorate disease and accelerate recovery, identifying potential targets for therapeutic intervention in patients. Great collaborative study within the DFG STBTRR237 Nucleic acid immunity consortium driven by students Nina Kessler and Susanne Viehmann.
