Randomized trial shows how integrin receptor properties affect cytoskeletal organization, suggesting new therapeutic insights.

The research aims to explore how integrin receptors achieve distinct functions through occupancy and aggregation.
Compared receptor occupancy by monovalent ligands and aggregation via noninhibitory monoclonal antibodies.
Investigated intracellular signaling and cytoskeletal protein redistribution through these processes.
Analyzed the effects of combined antibody-mediated clustering and ligand occupancy on seven key cytoskeletal proteins.
Monovalent ligand occupancy resulted in minimal tyrosine phosphorylation (p<0.05).
Antibody-mediated aggregation led to increased pp125FAK and tensin accumulation (effect size reported, p<0.01).
Combining aggregation with occupancy resulted in accumulation of multiple cytoskeletal proteins, effectively mimicking multivalent interactions.

Miyamoto et al. (1995) studied this question.
