title: Studies on the pathogenesis of experimental autoimmune renal tubulointerstitial disease in guinea pigs. VI. Induction of renal lesions by active or passive immunization of strain 2 guinea pigs.
abstract: It has been reported that strain 2 guinea pigs do not develop experimental autoimmune renal tubulointerstitial disease (RTD) by active or passive immunization. Under our experimental conditions strain 2 guinea pigs are susceptible to the induction of RTD. Typical moderate to severe renal lesions were seen 22 days after immunization with rabbit tubular basement membrane in complete Freund's adjuvant. Most Albany strain guinea pigs had severe RTD. Susceptibility to induction of RTD by passive transfer of antitubular basement membrane autoantibodies was studied in Albany (A) and strain 2 (2) guinea pigs, as well as in A leads to A, A leads to 2, and 2 leads to A radiation chimeras. Only some strain 2 guinea pigs had mild to severe renal lesions by day 9, but by day 19 all had typical histologic renal abnormalities. Albany guinea pigs already had moderate to severe RTD by days 9-10. Strain 2 differed from Albany recipients by a noticeable delay in the onset of lesions. Bone marrow transplants between Albany and strain 2 did not affect these susceptibility differences. A leads to 2 recipients responded like strain 2, and 2 leads to A like Albany. This indicates that the delay of onset of RTD in strain 2 is not a defect in the bone marrow-derived inflammatory cells.
