mortality/aging

immune system
• LPS-induced B cell proliferation is increased compared to in similarly treated wild-type mice
• T cell proliferation in response to anti-CD3, anti-CD3 plus anti-CD28, or PMA plus PHA is two- to six-fold more efficient than for similarly treated wild-type cells
• at 3 weeks
• in the bone marrow and peripheral blood
• the ratio of T to B cell is slightly decreased in the lymph node compared to in wild-type mice
• however, lymphocyte development is normal
• the percentage of T cells in the spleen is decreased compared to in wild-type mice
• at P10, CD4+CD8+ double positive thymic cells are nearly absent
• double positive T cells are nearly absent and single positive T cells predominate
• starting at P10 to P14
• at 3 weeks
• at 3 weeks
• after 2 weeks, the paracortical area is increased compared to in wild-type mice
• mice exhibit reduced number and cell density of lymphatic follicles compared to in wild-type mice
• after 2 weeks
• anti-CD3 and anti-CD28-stimulated production of cytokines IL2, IL4, IL10, GM-CSF (granulocyte monocyte colony stimulating factor), and TNF-alpha is increased 5- to 35-fold compared to in similarly treated wild-type cells
• following anti-CD3 and anti-CD28 stimulation
• following anti-CD3 and anti-CD28 stimulation
• following anti-CD3 and anti-CD28 stimulation
• following anti-CD3 and anti-CD28 stimulation

digestive/alimentary system
• mice exhibit hyperkeratosis in the cardiac portion of the stomach unlike in wild-type mice
• at 3 weeks, gastric abnormalities increase in severity until the gastric lumen is occluded unlike in wild-type mice
• in the antrum with lymphocytic infiltrate in the lamina propria
• at 2 weeks

growth/size/body
• at P10 to P14
• after P10 to P14, mice weight 25% to 30% less than wild-type mice
• after P10 to P14

behavior/neurological
• at 2 weeks, stomach contains little food or milk unlike wild-type mice
• after P10 to P14

skeleton

• fewer osteoclasts form while more bone-residing macrophages are detected compared to in wild-type mice
• tooth eruption is prevented by a superficial bone plate on the mandible and maxilla and impacted teeth are poorly invested in the surrounding alveolar bone unlike in wild-type mice
• however, mice reconstituted with wild-type marrow exhibit only delayed tooth eruption
• persistent cartilaginous and osseous trabecular are found throughout the epiphysis, metaphysis and diaphysis unlike in wild-type mice
• endochondral bones exhibit thin, hypocellular growth plates and wide, cavernous marrow spaces unlike in wild-type mice
• the proliferating and hypertrophic zones are arranged in irregular clusters unlike the discrete columns observed in wild-type mice
• the bone marrow cavity is filled with unresorbed primary spongiosa that reduces the space 80% compared to in wild-type mice
