Lung histology (Periodic acid-Schiff) staining of OVA-sensitized control (Q576) and Il4ratm2Tch/Il4ratm2Tch (R576) mice challenged intranasally with OVA on three consecutive days

respiratory system
• mutant mice exhibit airway inflammation following chronic allergen challenge
• increase in peribronchial and perivascular inflammation compared with control
• OVA sensitized and challenged mutant (R576) mice exhibit patchy peribronchial inflammatory infiltrate that is more prominent that in Q576 controls
• peribronchial infiltrate is composed primarily of eosinophils and lymphoctyes
• OVA or IL13 challenged mice exhibit goblet cell hyperplasia
• enhanced response to IL13 challenge

immune system
• increase in eosinophils found in lung parenchyma of OVA sensitized mutant mice
• increase in monocytes found in lung parenchyma of OVA sensitized mutant mice
• following immunization with OVA or alum
• stimulated Th2 cells exhibit an increase in IL4 production, but not IL5 or IL13
• stimulated Th2 cells exhibit an increase in IL4 production
• enhanced allergic inflammatory response following IL13 challenge
• mutant mice exhibit airway inflammation following chronic allergen challenge
• increase in peribronchial and perivascular inflammation compared with control

hematopoietic system
• increase in eosinophils found in lung parenchyma of OVA sensitized mutant mice
• increase in monocytes found in lung parenchyma of OVA sensitized mutant mice
• following immunization with OVA or alum
• stimulated Th2 cells exhibit an increase in IL4 production, but not IL5 or IL13

homeostasis/metabolism
• stimulated Th2 cells exhibit an increase in IL4 production
