Schedule of an allergic airway inflammation mouse model and treatment protocol. To induce allergic airway inflammation, mice in the OVA and OVA + antigen groups were sensitized on days 0 and 7 with an IP injection of OVA + alum and PBS. The OVA + antigen group received PSCs emulsified with PBS on these days. The PBS group received 0.5 ml of PBS on days 0 and 7. After the second sensitization, mice were challenged by exposure to aerosols of OVA and PBS on days 14, 15, and 16. Collection of BALF, lungs, and blood serum was performed 24 h after the last exposure. PSCs protoscoleces, OVA ovalbumin, Alum aluminum hydroxide, IP intraperitoneal, PBS phosphate-buffered saline, BALF bronchoalveolar lavage fluid
