HHT attenuates clinical symptoms associated with AD. (A) 2, 4-dinitro fluorobenzene (DNFB) induced AD. HHT (28 μg/kg) was intravenously injected at the indicated days of the time line. Clinical scores were determined as described. Each experimental group comprises five BALB/C mice. **p < 0.01; ***p < 0.001. (B) β-hexosaminidase activity assays were performed. ***p < 0.001. (C) The amount of histamine released was determined by using sera of BALB/C mice of each experimental group. **p < 0.01. (D) Same as (B) except that immunoblot and immunoprecipitation were performed. (E) Same as (D) except that lysates of skin mast cells isolated from skin tissue were employed. (F) Skin tissue lysates were subjected to qRT-PCR analysis.
