Spontaneous autoimmune disease in Fc(gamma)RIIB-deficient mice results from strain-specific epistasis.

abstract：:Class-switch recombination (CSR) is a DNA recombination process that replaces the immunoglobulin (Ig) constant region for the isotype that can best protect against the pathogen. Dysregulation of CSR can cause self-reactive BCRs and B cell lymphomas; understanding the timing and location of CSR is therefore important. ...
