immune system
• inflammatory cytokines, including Il2ra, Tnf, Icos, Il1b, Socs1, and Vcam1, are expressed in the suburothelial layer of mice that have anti-urothelial antibodies
• urinary cytokines, including GM-CSF, TNF-alpha, IL1-alpha, G-CSF, and IL-1beta, are upregulated in the urine of mice that have anti-urothelial antibodies
• anti-urothelial autoantibodies are seen in the serum as early as 7 weeks of age, with about 50% of mice showing autoantibodies at 10 weeks of age
• mice that are positive for anti-urothelial antibodies show massive infiltration of inflammatory cells at the suburothelial layer

renal/urinary system
• urinary cytokines, including GM-CSF, TNF-alpha, IL1-alpha, G-CSF, and IL-1beta, are upregulated in the urine of mice that have anti-urothelial antibodies
• mice that are positive for anti-urothelial antibodies show massive infiltration of inflammatory cells at the suburothelial layer
• mice that are positive for anti-urothelial antibodies show disarrangement of urothelial plaque on the surface of the bladder and disarranged cellular structure of the bladder epithelium at 16 weeks of age
• surface of bladder epithelium shows poorer plaque formation, exposing bare surface of smaller epithelial cells beneath it, in mice that are positive for anti-urothelial antibodies
• mice that are positive for anti-urothelial antibodies void less urine per void than wild-type mice, even when corrected for body weight

homeostasis/metabolism
• inflammatory cytokines, including Il2ra, Tnf, Icos, Il1b, Socs1, and Vcam1, are expressed in the suburothelial layer of mice that have anti-urothelial antibodies
• urinary cytokines, including GM-CSF, TNF-alpha, IL1-alpha, G-CSF, and IL-1beta, are upregulated in the urine of mice that have anti-urothelial antibodies

growth/size/body
• lower body weight in mice that are positive for anti-urothelial antibodies
