immune system
• mastocytosis in lungs of infected mice does not occur in mutants; 8-fold fewer mast cells are found compared to wild-type
• granulomas of equivalent size and granularity develop in mutants and wild-type upon infection with parasite eggs (J:82881)
• a secondary challenge induces equivalent levels of goblet cell and mast cell induction, as in wild-type (J:82881)
• upon infection with Schistosoma mansoni eggs, primary granuloma formation and volume is equivalent to wild-type (J:113543)
• volumes of secondary granulomas after second exposure with parasite eggs are similar to wild-type (J:113543)
• after primary infection with Schistosoma mansoni eggs, expansion of goblet cell population in airways and mast cell population in lungs does not occur, in contrast to wild-type response
• upon nematode infection (N. brasiliensis), fewer goblet cells are found in mutants

digestive/alimentary system
• after primary challenge with parasite eggs, goblet cell hyperplasia along the airway epithelia does not develop like in wild-type; mutants have 10-fold fewer goblet cells than wild-type
• upon nematode infection (N. brasiliensis), fewer goblet cells are found in mutants

hematopoietic system
• mastocytosis in lungs of infected mice does not occur in mutants; 8-fold fewer mast cells are found compared to wild-type

homeostasis/metabolism
• in jejunal homogenates, mast cell protease (mMCP-1) activity is reduced compared to wild-type after nematode infection

cellular
• after primary challenge with parasite eggs, goblet cell hyperplasia along the airway epithelia does not develop like in wild-type; mutants have 10-fold fewer goblet cells than wild-type
• upon nematode infection (N. brasiliensis), fewer goblet cells are found in mutants
