title: An effect of actin on cell migration.
abstract: A specific inhibitory effect on mononuclear cell migration by smooth muscle actin and skeletal muscle actin is reported. Actin aged at 4 degrees C or heated at 56 degrees C for 10 min had little or no effect, but papain-denatured actin had a strong inhibitory action. Actin and/or its breakdown product(s) may interfere with mononuclear cell movement in vivo in pathological conditions where release of actin from damaged or dead cells occurs.
