Key result
Transfer of IgG and peripheral blood lymphocytes from rabbits immunized with beta1 and M2 peptides reproduced early-stage cardiomyopathic changes in SCID mice.
Why the study?
Does transfer of immune components from rabbits with autoimmune cardiomyopathy induce cardiomyopathic changes in SCID mice?
Does transfer of immune components from rabbits with autoimmune cardiomyopathy induce cardiomyopathic changes in SCID mice?
Passive transfer of IgG and lymphocytes from rabbits with autoimmune cardiomyopathy reproduces early cardiomyopathic changes in SCID mice, supporting an autoimmune mechanism in cardiomyopathy pathogenesis.

Supports autoimmune transfer in experimental cardiomyopathy; extends mechanistic data but leaves open human relevance and therapeutic targeting.
Matsui et al. (2005) studied Autoimmune cardiomyopathy (n=35). Transfer of IgG and/or peripheral blood lymphocytes (PBL) from immunized rabbits vs. IgG and/or PBL from rabbits with adjuvant and control groups was evaluated on Cardiomyopathic changes (heart weight, autoantibody titers, histological changes). Transfer of IgG and peripheral blood lymphocytes from rabbits immunized with beta1 and M2 peptides reproduced early-stage cardiomyopathic changes in SCID mice.
