Extended Data Fig. 3. Autoantibodies to ssDNA but not dsDNA are a feature of kika mice and are detectable by 6 wks of age.

Extended Data Fig. 3

(a) Quantification of ANAs in 12 wk-old kika mice by Hep-2 immunofluorescence (IF). (b) Proportion of 6 month-old WT and kika mice positive for dsDNA according to Crithidia luciliae IF, and representative images (c) for each genotype. (d) Autoantibodies to DNA in serum from 4 wk-old (n = 10) and 6 wk-old (n = 9) wt or kika mice. (e) HEp-2 IF showing pattern and quantification of ANAs in 6 wk-old kika mice. (f) Mesoscale measurement of cytokines in serum from wt or kika mice (n = 20). (g) Dose-dependent response of TLR7 to guanosine (data averaged from two mice in biological triplicate). (h) Responsiveness of TLR7 to ssRNAs lacking uridine (ss41-L), with 6 to 10 uridines; or 9 uridines B-406-AS1 (data represent mean ± s.e.m. averaged from three mice in biological triplicates). Unpaired t-test (d, h); Mann-Whitney test (f). Exact p values are shown.
