To validate the role of STING in the pathogenesis of endometritis and the formation of NETs, the levels of key NETs markers, ELA2 (Figures 3A, B) and citH3 (Figures 3C, D) were assessed in both WT and STING-deficient intrauterine mice following LPS injection using immunofluorescence staining. This evidence concerns the gene STING1 and endometritis.
