title: Antibody to integrin alpha 6 subunit specifically inhibits cell-binding to laminin fragment 8.
abstract: A large number of cell lines which attach and spread on laminin show a comparable binding either to both laminin fragments P1 and E8 or exclusively to E8. Adhesion to fragment E8 was with one exception completely inhibited by a monoclonal antibody to the alpha 6 integrin subunit, indicating that VLA-6 or a related structure is the major cellular receptor for laminin. It is not involved in fragment P1 adhesion. Synthetic peptides possessing RGD or YIGSR sequences were without inhibitory activity for alpha 6-mediated adhesion to fragment E8.
