Expression of Cyclic GMP‐AMP Synthase in Patients With Systemic Lupus Erythematosus

Abstract

Increased cGAS expression and cGAMP in a proportion of SLE patients indicates that the cGAS pathway should be considered as a contributor to type I IFN production. Whereas higher cGAS expression may be a consequence of exposure to type I IFN, detection of cGAMP in patients with increased disease activity indicates potential involvement of this pathway in disease expression.
