Fig. 1. T. gondii infection inhibits atopic dermatitis in NC/Nga mice. (A) Experimental schedule for the development of DfE-induced atopic dermatitis and T. gondii infection in NC/Nga mice. (B) Skin lesions developed by NC/Nga mice treated with DfE. T. gondii was injected 7 days before (Tg+DfE) or after (DfE+Tg) the first DfE application. White and yellow arrows indicate excoriation and desquamation, respectively. (C) The dermatitis score was based on the severity of four symptoms (erythema, scarring, edema, and erosion): 0, no symptoms; 1, mild; 2, intermediate; 3, severe. ^***P<0.001 compared with uninfected NC/Nga mice. Graph represent the mean±SD (n=5) of one experiment (three experiments with comparable results were performed). Tg, T. gondii; DfE, Dermatophagoides farinae extract.
