Crescentic glomerulonephritis (cGN) is the most aggressive form of glomerulonephritis in humans. A widely studied mouse model is induced by sheep or rabbit antisera raised against murine renal cortical antigens. We here, report that Alpaca readily produce ample amounts of antisera that induces pathology in mice, resembling human disease regarding crescent formation, proteinuria, infiltrating immune cells and a significant Th1, but not Th17 immune response. Alpaca antiserum did not cause end-stage kidney failure, neither in a passive nor in an accelerated experimental setting, which may be advantageous for long term studies of crescentic glomerulonephritis.
