mortality/aging
• only about half survive past weaning
|
• 50% of animals survived past weaning when derived from parental mice also heterozygous for a knockout of the Ugcg gene
|
growth/size/body
• after 50 days of age body weight is 15% less than wild-type controls
|
• slight increase in liver weight
|
• slight increase in spleen weight
|
cardiovascular system
• Kupffer cells are amoeboid in shape rather than having a ramified structure, indicating an activated state
|
cellular
• apoptotic hepatocytes are seen in inflammatory lesions
|
respiratory system
• lungs show aggregations of inflammatory cells consisting of neutrophils, lymphocytes, and macrophages
|
hematopoietic system
• slight increase in spleen weight
|
• red blood cell counts are 88.8% of control values
|
• hematocrit levels are 88.7% of control values
|
• hemoglobin levels are 91.8% of control values
|
• white blood cell counts are 62% of controls
• however, platelet counts are normal
|
• 7 month old mice have abnormal swollen, multinucleated macrophages with lipofuscin granules and tubular structures in the liver
• however, no Gaucher-like cells of characteristic wrinkled tissue paper appearance are seen in the liver, spleen, bone marrow, lymph nodes, lung, or brain
|
• Kupffer cells are amoeboid in shape rather than having a ramified structure, indicating an activated state
|
homeostasis/metabolism
• total serum cholesterol level is lower
|
• liver enzyme alanine aminotransferase is 141% of control levels, indicating liver damage
|
• liver enzyme aspartate aminotransferase is 160% of control levels, indicating liver damage
|
• acid beta-glucosidase activity in several organs is 15-20% of normal activity
• chitotriosidase levels are modestly elevated in the serum
• however, acid phosphatase and ACE levels are not elevated
• abnormal glycosylceramide accumulation in the liver, spleen, or brain is not seen
|
integument
• infiltration of inflammatory cells in the upper dermis
|
• stratum corneum is thickened
|
immune system
• slight increase in spleen weight
|
• white blood cell counts are 62% of controls
• however, platelet counts are normal
|

|
• inflammation is seen in the spleen, with excessive neutrophil infiltration in the red pulp
|
• multi-organ system inflammation
|
• mice exhibit lymphadenitis, with cervical, axillary, inguinal, and mesenteric lymph nodes affected
• large numbers of plasma cells are seen in the lymph nodes, indicating plasmacytosis
|
• inflammatory lesions in the liver are seen as early as 1 month of age, are scattered throughout the liver, and contain macrophages, lymphocytes, and neutrophils
|
• lungs show aggregations of inflammatory cells consisting of neutrophils, lymphocytes, and macrophages
|
• infiltration of inflammatory cells in the upper dermis
|
liver/biliary system

|
• slight increase in liver weight
|
• inflammatory lesions in the liver are seen as early as 1 month of age, are scattered throughout the liver, and contain macrophages, lymphocytes, and neutrophils
|
pigmentation

|
skeleton
N |
• no histological abnormalities of the bones are seen
