Leukocyte locomotory function in children with the immotile cilia syndrome.

The random motility of polymorphonuclear leucocytes (PMN), cellular chemotaxis and chemokinesis in kinetic fashion in 4 patients with immotile cilia syndrome (ICS) have been evaluated. No impairment of granulocyte ability of orientation and migration was found. Ultrastructural alterations of cilia which are the primary factor in the pathogenesis of respiratory tract disease in patients with ICS do not impair the PMN function.
