Abstract

DESCRIPTION (provided by applicant): Our lab is focused on understanding how pathogenic immune complexes (IC) formed from DNA and/or RNA and antibodies contribute to the pathogenesis of systemic lupus erythematous (SLE). We use in vitro and in vivo models to determine the molecular mechanisms that govern the activation of immune cells by DNA and/or RNA antibody complexes. This particular project is investigating how IC trafficking within immune cells affects the functional outcome. We have developed novel ICs that are also pH sensors. Using these ICs we can rapidly screen the effect of genetic factors and therapeutic agents on IC trafficking in B cells and phagocytes.
