Cysltr2tm1Ykn mutation (2 available); any Cysltr2 mutation (31 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
decreased susceptibility to type I hypersensitivity reaction ( J:94488 )
• IgE-dependent plasma protein extravasation in the ear is reduced by about 65% 30 minutes after antigen challenge, however zymosan A-induced peritoneal inflammation is normal

respiratory system
pulmonary fibrosis ( J:94488 )
• lung tissue from bleomycin-treated homozygotes had less septal thickening, with fewer monocytes/macrophages, giant cells, fibroblasts, and eosinophils, and less extracellular matris deposition compared to wild-type mice
• the area of the lower lobes with alveolar septal thickening in bleomycin traeted mutant mice is reduced to 39% of wild-type

homeostasis/metabolism
abnormal prostaglandin level ( J:94488 )
• bleomycin treatment did not increase prostaglandin E2 levels in mutant mice

immune system
autoimmune response ( J:182213 )
• mutants exhibit impaired epidermal and dermal thickening and collagen deposition in OVA-sensitized skin compared to wild-type mice

integument
abnormal skin physiology ( J:182213 )
• mutants exhibit impaired epidermal and dermal thickening and collagen deposition in OVA-sensitized skin compared to wild-type mice
