Figure Lengend Snippet: A) After baseline measurements on day 0, subcutaneous treatment injections were administered on day 1 and 8. Intermediate testing and blood collection were performed on day 4, 7 and 11 (not shown). On day 15, indicated with a red arrow, PTMG was induced using mAb35, while non-MG animals received a saline injection of the same volume. B-C) Plasma C3 expression was reduced by the sc administration of C3-siRNA at various dose levels in B) non-MG animals and C) PTMG animals. For animals receiving 2 x 30 mg/kg treatment, doses were administered on days 1 and 8. For animals receiving 1 x 10 or 1 x 30 mg/kg doses, administration occurred on day 8, as indicated by the black arrows on the graphs. Saline-treated animals showed no significant change in C3 levels over time. Group averages are shown. D) Plasma C3 level changes in individual treatment groups on day 17, normalized to baseline levels on day 0. Individual plasma C3 levels per animal are shown. Statistical analysis was performed with Two-Way ANOVA (B-D), followed by One-Way ANOVA and post-hoc Bonferroni’s multiple comparison test (D); α=0.05; ****p<0.0001. A) Created in BioRender.

Figure Lengend Snippet: C3 protein levels in plasma of healthy animals receiving a single treatment injection to establish the dose range of C3-siRNA for the PTMG study. After baseline measurements on day 0, C3-siRNA was administered on day 1 (black arrow) and plasma C3 protein levels analyzed on days 3, 8, 15, 22, and 29. Per group N=3. Group averages are shown.

Figure Lengend Snippet: C3 protein levels in plasma of healthy animals receiving three consecutive treatment injections, with a cumulative dose equal to a single injection as shown in . After baseline measurements on day 0, C3-siRNA was administered on day 1, 2, and 3 (black arrows) and plasma C3 protein levels analyzed on day 3, 8, 15, 22 and 29. Per group N=3.

Figure Lengend Snippet: Three days after treatment injection, hepatic C3 mRNA expression was significantly repressed in all C3-siRNA treated animals (left). 30 days after C3-siRNA injection, the expression was still reduced to 50% and ca. 25% in animals that received 10 or 30 mg/kg C3-siRNA (single and cumulative) compared to control animals. Each dot indicates one animal. Statistical analysis as performed using One-Way ANOVA with post-hoc Bonferroni’s multiple comparison test; α=0.05; **p=0.003, ***p<0.0004, ****p<0.0001.

Figure Lengend Snippet: One PTMG animal treated with 30 mg/kg C3-siRNA showed no siRNA in the liver. Assuming a misinjection of C3-siRNA, this animal was excluded from the analysis.

Figure Lengend Snippet: A) Grip strength decreased in PTMG animals after disease induction (red arrow) with a dose-dependent effect of the C3-siRNA treatment. B) Grip strength on day 17 with non-MG animals pooled into one group. C) Disease scoring increased in PTMG animals after disease induction (red arrow), with an evident dose dependent effect of the C3-siRNA treatment. D) Disease score on day 17 with non-MG animals pooled into one group. In A) and C) group averages are shown. In B) and D) each dot represents one individual animal; horizontal bars indicate group means.
