Self-limited autoimmune disease related to transient donor B cell activation in mice neonatally injected with semi-allogeneic F1 cells.

abstract：:Under equilibrium conditions, the affinities of five anti-IgG2a mAb isolated from virus-infected mice were comparable to other high-affinity auto-antibodies. Similar to rheumatoid factors, these anti-IgG2a auto-antibodies bound to aggregated or complexed IgG2a with 50 to 1500-fold higher avidity than their monomeric c...
