The Epstein-Barr virus BNLF-1 membrane protein LMP1 induces homotypic adhesion mediated by CD11a/CD18 in a murine B-cell line mimicking the action of phorbol ester.

摘要

Expression of the Epstein-Barr virus BNLF1 gene (LMP1) or treatment with 4B-phorbol-12,13-dibutyrate in the murine pro-B-cell line A/J-95 leads to a five- to sevenfold enhancement of homotypic adhesion without significant changes in adhesion molecule expression. Antibody to CD11a inhibits aggregation, indicating that CD11a/CD18-mediated adhesion is a common target for both agents.
