Niclosamide ameliorates disease aggravation in R848-induced mice. Female 8-week-old C57BL/6 mice were treated with 50 μg of the TLR7 agonist R848 or control (acetone) three times weekly and were orally administered 0.5% methyl cellulose (control, R848, n = 4–6), or 100 mg/kg niclosamide (niclosamide, n = 7) daily until they were 12-week-old. a Representative photographs documenting the enlargement of spleens and cLNs. b Spleen lengths and weights in each group. c cLN lengths and weights in each group. d Urine albumin levels normalized to creatinine. e Serum levels of anti-dsDNA IgG antibody. f Serum levels of antibody subclasses (IgG, IgG2a). g Serum levels of IL-6, IL-21. h Left, representative photomicrographs of PAS-stained sections of kidney. Original magnification ×200 (upper), ×100 (bottom). Right, histological scores. i Left, representative immunofluorescent images of kidney C3 staining. Original magnification ×100 (upper), ×400 (bottom). Right, MFI of C3 deposition. Data shown as mean ± SD. One-way ANOVA was performed. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, ns: not significant
