In the present study, we have characterized the transcriptional induction of p40 by CD40 ligation in a human B lymphoblastoid cell line , Daudi , and a human acute monocytic leukemia cell line , THP-1 .
 ( cell line: human acute monocytic leukemia cell line, None) , ( cell line: human B lymphoblastoid cell line, None) , ( protein: CD40, None) , ( protein: p40, None) , ( cell line: Daudi, None) , ( cell line: THP-1, None)
