CXCR3 and pulmonary fibrosis: In this context, while the mechanistic action of several autoantibodies that we identified remains to be investigated, we previously described13,15,52,53 that anti-AGTR154 and anti-CXCR3 (previous work55 and unpublished data) have agonist properties (e.g., on cell migration) and associate, for instance, with pulmonary fibrosis and cardiac death.
