Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Gzmbtm2.1Ley mutation (1 available); any Gzmb mutation (27 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
decreased cytotoxic T cell cytolysis ( J:96538 )
• using a flow-based killing assay, CTLs from mutant mice showed a less severe cytotoxic defect than CTLs from Gzmbtm2Ley homozygous mice

hematopoietic system
decreased cytotoxic T cell cytolysis ( J:96538 )
• using a flow-based killing assay, CTLs from mutant mice showed a less severe cytotoxic defect than CTLs from Gzmbtm2Ley homozygous mice
