To delineate the role the immune response might play, we have developed a passive model with exclusive IgA-immune complex-mediated nephropathy in B-cell-deficient (BCD) mice. Glomerular IgA immune deposits were induced by administration of purified IgA antiphosphorylcholine and the specific pneumococcal C-polysaccharide (PnC) antigen daily for 2 weeks into BCD and wild-type (WT) mice. In BCD mice IgA+PnC deposits induced severe glomerular injury and renal dysfunction. In contrast, WT mice developed intense glomerular IgG and IgM and C3 co-deposits of the IgA+PnC with significantly less renal injury. Cytofluorometric analysis revealed that PnC induced in BCD, but not in WT, a rapid and dramatic increase in number of activated CD3(+)/CD69(+) T-cell population. The nuclear factor-kappa B (NF-kappaB) transcription factor was activated early and progressively increased in response to glomerular IgA+PnC deposits. These results suggest that nephritogenic IgA+PnC immune deposits induce glomerular and renal dysfunction through activation of the NF-kappaB. This inflammatory pathway is modulated by the endogenous cellular and antibody response to the antigen affecting the course of IgA nephropathy progression. ------>tmu_sno=None ------>sno=15561 ------>authors2=Abdalla R ------>authors3=Ka SM ------>authors4=Shui HA ------>authors5=Lin YF ------>authors6=Sytwu HK,LEE WH,Kungg JT,Chen A ------>authors6_c= ------>authors=Chao TK ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=The endogenous immune response modulates the course of IgA-immune complex mediated nephropathy. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=2 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2006 ------>submit_flag=None ------>publish_month=7 |
