- 126 - Abstract BINDING PROTEINS, INCLUDING ANTIBODIES, ANTIBODYDERIVATIVES AND ANTIBODY FRAGMENTS, THAT SPECIFICALLY BIND CD154 ANDUSES THEREOF This invention provides binding proteins, includingantibodies, antibody derivatives and antibody fragments, thatspecifically bind a CD 154 (CD4OL) protein. This invention alsoprovides a chimeric, humanized or fully human antibody, antibodyderivative or antibody fragment that specifically binds to an epitopeto which a humanized Fab fragment comprising a variable heavy chainsequence according to SEQ ID NO: 1 and comprising a variable lightchain sequence according to SEQ ID NO: 2 specifically binds. CD154binding proteins of this invention may elicit reduced effectorfunction relative to a second anti-CD154 antibody. CD154 bindingproteins of this invention are useful in diagnostic and therapeuticmethods, such as in the treatment and prevention of diseasesincluding those that involve undesirable immune responses that aremediated by CD154-CD40 interactions.
