Figure 1. Il17ra L-SNAs improve the clinical and histological psoriatic phenotype induced by imiquimod inC57BL/6 mice.
(a) Representative clinical pictures on day 6 before harvesting of back skin. (b) Mean reduction in daily modified Psoriasis Area and Severity Index , as assessed by three blinded reviewers. (c) Routine H&E (above) and Ki67 (below) staining of day 6-harvest mouse skin. Bars = 100 μm. (d) Epidermal thickness from the stratum granulosum to the epidermal-dermal junction. (e) Number of Ki67 + cells per linear length of basal epidermis. (f) Ratio of qRT-PCR levels compared to mouse skin with only vehicle and no IMQ. (g) Representative western blot from harvested skin. Values reported are the mean ± standard error of the mean from three separate experiments. *P < 0.05, ***P < 0.001. H&E, hematoxylin and eosin; IL-17RA, IL-17A receptor; IMQ, imiquimod; qRT-PCR, quantitative real-time reverse transcriptase–PCR; Scr L-SNA, scrambled liposomal spherical nucleic acid.
