mortality/aging
• following administration of 60 or 120 ug cholera toxin

immune system
N |
• mice exhibit normal immunoglobulin concentrations in serum and feces
|
• germinal center B cells from naive and immunized mice exhibit reduced somatic hypermutation compared with cells form wild-type mice
|
• in Peyer's patches and spleen
|
• mice immunized with sheep red blood cells (SRBC) exhibit a reduction in anti-SRBC IgG1 compared with similarly treated wild-type mice
• splenocytes stimulated with LPS and IL4 produce less IgG1 compared with similarly treated wild-type cells
• however, total IgG1 levels are normal
|
• mice exposed to Y. enterocolitica exhibit increased numbers in mesenteric lymph nodes compared with similarly treated wild-type mice
|
• following administration of 60 or 120 ug cholera toxin
|
digestive/alimentary system
• mice exhibit an increase in bacteria, especially anaerobic bacteria, in the small intestine compared with wild-type mice
• some mice exhibit an expansion of unclassified Lachnospiraceae of the order Clostridiales while others exhibit increased Bacteroidales or Lactobaccillus compared with wild-type mice
