mortality/aging
• mice survive doses of LPS that are 100 times as much as the dose that would kill a wild-type mouse
• mice cannot control a dose Listeria monocytogenes that is tolerated by wild-type mice and eventually die from listeriosis with high liver and spleen titers and large necrotic lesions with boundaries of heavily infected hepatocytes

immune system
• CD3+ T cells are decreased (25%+/-3% compared to 45%+/-3% in wild-type mice)
• peripheral T cells are decreased 2-fold compared to wild-type
• leukocyte cell number is increased 4-fold compared to wild-type
• 65%+/-4% B220+ B cells compared to 44%+/-2% in wild-type mice
• peripheral B cells are increased 6-fold compared to wild-type
• spleen lymphocyte composition and micro-architecture are altered
• the T cell zones are lost and the marginal zone is ill-defined
• the marginal zone is ill-defined
• mice are unable to mount a primary IgG response to sheep red blood cells
• mice cannot control a dose Listeria monocytogenes that is tolerated by wild-type mice and eventually die from listeriosis with high liver and spleen titers and large necrotic lesions with boundaries of heavily infected hepatocytes
• response to VV-WR infection is slightly reduced
• response to LCMV-ARM is strongly reduced
• when footpads are infected with LCMV-ARM or LCMV-WE they fail to swell as in wild-type mice

hematopoietic system
• CD3+ T cells are decreased (25%+/-3% compared to 45%+/-3% in wild-type mice)
• peripheral T cells are decreased 2-fold compared to wild-type
• leukocyte cell number is increased 4-fold compared to wild-type
• 65%+/-4% B220+ B cells compared to 44%+/-2% in wild-type mice
• peripheral B cells are increased 6-fold compared to wild-type
• spleen lymphocyte composition and micro-architecture are altered
• the T cell zones are lost and the marginal zone is ill-defined
• the marginal zone is ill-defined
