Abstract
Antibody evolution in vivo proceeds mainly by stepwise improvements, accomplished by single base pair substitutions. Lately, receptor revision, i.e. exchange of large parts of the V gene for another sequence, has been suggested to provide a complementary route for affinity maturation. By employing a receptor revision like evolution process in vitro using combinatorial libraries and phage display selection, we demonstrate here that maturation of a clone may preferentially proceed through exchange of a large gene segment rather than via minor sequence changes. These modifications of a CD40-specific human antibody fragment outline how receptor revision like events may provide an advantage to a particular clonotype put under selective pressure.
