Allelic
Composition		 Tacr1tm1Nge/Tacr1tm1Nge
Genetic
Background		 involves: 129S4/SvJae
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Tacr1tm1Nge mutation (0 available); any Tacr1 mutation (40 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
abnormal humoral immune response ( J:35529 )
• after injection of chicken egg albumin in the tail and administration of antibodies to egg albumin intratracheally, the null mice exhibit almost complete protection from inflammatory response upon examination of lung tissue

nervous system
abnormal nervous system electrophysiology ( J:106546 )
• at stimulus frequencies of 0.2 and 1 Hz, C-fiber responses progressively increase in wild-type, but in mutants there are significantly less frequency dependent increases

cardiovascular system
decreased vascular permeability ( J:84660 )
• do not display increased vascular permeability in the dura mater in response to acute restrain stress as is seen in wild-type controls

immune system
abnormal mast cell physiology ( J:84660 )
• acute restrain stress does not result in increased dura mast cell activation as in wild-type

hematopoietic system
abnormal mast cell physiology ( J:84660 )
• acute restrain stress does not result in increased dura mast cell activation as in wild-type
