mortality/aging
• mutant mice have a higher survival rate of 58% compared to 35% in wild-type controls following infection with genital herpes simplex type 2

immune system
• mice are more susceptible to Giardia muris infection compared to controls
• seven weeks after infection, mice have over 1,000-fold higher trophozoite numbers in the small intestine compared with controls
• mice are less susceptible to genital herpes simplex type 2 infection
• mice exhibit fewer severe vaginal symptoms following HSV-2 genital infection, with 27 of 31 WT mice developing a vaginal symptom score of 2 or greater compared with 18 of 31 mutant mice
• mutant mice have a higher survival rate of 58% compared to 35% in wild-type controls following infection with genital herpes simplex type 2

liver/biliary system
• IgA levels in the bile are 3.5-fold lower than in controls
• the IgA present in the bile is mostly in a monomer state compared to the dimeric state that predominates in wild-type bile

immune system
• production of dimeric IgA is severely curtailed in these mice
• serum IgA levels are about 35-fold higher (J:34042)
• IgA levels found in bronchoalveolar lavage fluid are 8- to 18- fold higher than in controls (J:34042)
• IgA is often in monomeric form in the serum and mucosal fluids (J:34042)
• IgA levels in mucosal secretions and breast milk are not significantly different from controls (J:34042)
• serum IgA levels are over 30-fold higher than in controls (J:75843)
• monomer to dimer is 10:1 ratio compared to 1:1 in wild-type (J:75843)

digestive/alimentary system
• while levels of IgA are normal in intestinal fluids, monomeric forms of IgA are found in these fluids that are not found in wild-type controls (J:34042)
• fecal levels of IgA are 5.5-fold lower than in controls (J:75843)

endocrine/exocrine glands
• monomeric forms of IgA are found in the breast milk while the dimeric form of IgA predominates in wild-type breast milk

integument
• monomeric forms of IgA are found in the breast milk while the dimeric form of IgA predominates in wild-type breast milk

hematopoietic system
• production of dimeric IgA is severely curtailed in these mice
• IgA levels found in bronchoalveolar lavage fluid are 8- to 18- fold higher than in controls (J:34042)
• IgA is often in monomeric form in the serum and mucosal fluids (J:34042)
• serum IgA levels are about 35-fold higher (J:34042)
• IgA levels in mucosal secretions and breast milk are not significantly different from controls (J:34042)
• serum IgA levels are over 30-fold higher than in controls (J:75843)
• monomer to dimer is 10:1 ratio compared to 1:1 in wild-type (J:75843)
