Gene targeted mice were made wherein the IgH locus of germline D gene segments (~ 80 kb) was deleted by Cre-loxP engineering in ES cells.  The locus was replaced by a single D gene element -- either germline DFL16.1 (encoding Tyr, Ser, and Gly) or an inverted DFL16.1 (encoding the charged residues Arg and His and Asp).  This was sufficient to globally alter CDR-H3 sequence repertoire, to significantly perturb B-cell development, and resulted in impaired B-cell function and antibody production.  

The work in this dissertation has been published.
