The Motor of Leukocytes and Platelets: 1986
Arterial wall injury is believed to involve, among other factors, the interaction of platelets and leukocytes with endothelial cells. Shape changes and movements including spreading, locomotion and secretion (platelets and leukocytes) and rounding (endothelial cells) originate in a motor in the cortical cytoplasm. This is the domain of the actin cytoskeleton. Actin regulated by actin-binding proteins and signal molecules may produce mechanical effects that account for the cell functions described.
