mortality/aging
• mice are resistant to mortality from acute L. monocytogenes infection (40% mortality) compared to wild-type (80% mortality)
• mutants develop long-term immunity
|
immune system
N |
• mutants show similar expression and production of monocyte-, natural killer- and T-cell derived inflammatory cytokines and chemokines, as well as granulopoietic cyto- and chemokines compared to wild-type
• granulocytes from mutants show similar migratory properties to wild-type in vivo and in vitro
|
• adult mice show a mild peripheral granulocytosis upon necropsy
• in peripheral blood, mutants have 2-fold more basal granulocytes than wild-type before infection; at 1 day post infection, there are ~50% more granulocytes than in wild-type
|
• at 8 hours after infection with L. monocytogenes, less bacteria are recovered from spleens and livers of mutants compared to wild-type
• at 72 hours, mutants have 3-fold fewer microabscesses than wild-type

• mice are resistant to mortality from acute L. monocytogenes infection (40% mortality) compared to wild-type (80% mortality)

hematopoietic system
• adult mice show a mild peripheral granulocytosis upon necropsy
• in peripheral blood, mutants have 2-fold more basal granulocytes than wild-type before infection; at 1 day post infection, there are ~50% more granulocytes than in wild-type
