mortality/aging
• mean age of death is 20 weeks
|
• death sometime between E14 and 4 weeks of age
|
neoplasm
• tumors were largely confined to the large intestine with none being observed in the small intestine
|
digestive/alimentary system
• with heavy chronic infiltration of lymphocytes and active plasma cells
|
• loss of mucus from goblet cells of crypts, atypia and loss of crypts
• glands regenerate with typical characteristics of adenocarcinomas as well as penetrating the submucosa and extending to the smooth muscle layer
|
• colons were irregularly dilated and had focally thickened and inflamed walls
(J:24434)
• the small intestines were unaffected
(J:24434)
• at necropsy walls are focally thickened
(J:30507)
|
• tumors were largely confined to the large intestine with none being observed in the small intestine
|
• seen in 21 of 26 mice
• inflammation is restricted to the rectum and colon
• diffuse but not patchy pattern of inflammation resembles ulcerative colitis
|
• exhibited by all mice by 13 weeks of age
• chronic active inflammation with the distal colon being most affected
|
• serosal discoloration and increased vascularity are also observed at necropsy
• perforation and peritonitis are present at necropsy
|
immune system
• at 8 weeks, the spleen contain a significantly larger number of granulocytes compared to wild-type mice
|
• 3-fold increase in CD3+ cells
|
• 2- to 4-fold increase in single positive thymocytes
|
• proliferative response to phorbol myristate acetate (PMA), staphylococcal enterotoxin A (SEA) and BABL/c(H-2s) is increased by 3- to 5-fold
|
• myeloperoxidase (MPO) levels from neutrophils are significantly lower than in wild-type at the site of infection
• however, neutrophil function is normal and serum taken from immunized mice is able to confer immunity to nae wild-type mice
|
• twice as high as in wild-type mice
|
• twice as high as in wild-type mice
• markedly elevated in the large intestine but only modestly so in the small intestine
|
• IFN-gamma levels in non-immunized and immunized mice are increased compared to immunized wild-type mice
|
• IL-4 levels are significantly higher after immunization against S. stercorallis
|
• IL-5 levels are significantly higher after immunization against S. stercorallis
|
• stimulated spleen and lymph node T cells and thymocytes produce several fold more INF-gamma
|
• stimulated spleen and lymph node T cells and thymocytes produce several fold more IL-2
• however, IL-4 production from stimulated spleen and lymph node T cells and thymocytes is only modestly enhanced if at all
|
• stimulated spleen and lymph node T cells and thymocytes produce several fold more TNF
|
• seen in 21 of 26 mice
• inflammation is restricted to the rectum and colon
• diffuse but not patchy pattern of inflammation resembles ulcerative colitis
|
• exhibited by all mice by 13 weeks of age
• chronic active inflammation with the distal colon being most affected
|
• serosal discoloration and increased vascularity are also observed at necropsy
• perforation and peritonitis are present at necropsy
|
• following immunization and exposure to S. stercorallis, mice have decreased larval killing of 37% compared to 91% in wild-type mice
• IL-4 and IL-5 levels are significantly higher after immunization against S. stercorallis
• fewer neutrophils, eosinophils, macrophages, and lymphocytes are recruited into the site of infection
• myeloperoxidase (MPO) levels from neutrophils are significantly lower than in wild-type at the site of infection
• however, serum taken from immunized mice is able to confer immunity to nae wild-type mice
|
growth/size/body
• at 6 weeks, mice gain weight slower
|
weight loss
(
J:30507
)
• at 6 weeks, mice gain weight slower
|
homeostasis/metabolism
• IFN-gamma levels in non-immunized and immunized mice are increased compared to immunized wild-type mice
|
• IL-4 levels are significantly higher after immunization against S. stercorallis
|
• IL-5 levels are significantly higher after immunization against S. stercorallis
|
• response to prostoglandin E and nicotinic acid is blunted about 50%
|
• inhibition of adenylyl cyclase in response to phenylisopropyl adenosine or carbachol is blunted about 50%
|
• proliferative response to phorbol myristate acetate (PMA), staphylococcal enterotoxin A (SEA) and BABL/c(H-2s) is increased by 3- to 5-fold
|
hematopoietic system
• proliferative response to phorbol myristate acetate (PMA), staphylococcal enterotoxin A (SEA) and BABL/c(H-2s) is increased by 3- to 5-fold
|
• at 8 weeks, the spleen contain a significantly larger number of granulocytes compared to wild-type mice
|
• 3-fold increase in CD3+ cells
|
• 2- to 4-fold increase in single positive thymocytes
|
• myeloperoxidase (MPO) levels from neutrophils are significantly lower than in wild-type at the site of infection
• however, neutrophil function is normal and serum taken from immunized mice is able to confer immunity to nae wild-type mice
|
• twice as high as in wild-type mice
|
• twice as high as in wild-type mice
• markedly elevated in the large intestine but only modestly so in the small intestine
|
endocrine/exocrine glands
• loss of mucus from goblet cells of crypts, atypia and loss of crypts
• glands regenerate with typical characteristics of adenocarcinomas as well as penetrating the submucosa and extending to the smooth muscle layer
|
cellular
• proliferative response to phorbol myristate acetate (PMA), staphylococcal enterotoxin A (SEA) and BABL/c(H-2s) is increased by 3- to 5-fold
