The effects of serum from patients with chronic lymphocytic leukaemia (CCL) on normal polymorphonuclear leucocyte migration (PMN) were examined by means of the leading front technique, using a modified Boyden chamber. 18 randomly selected patients were studied. 13 patients had a reduced chemokinetic activity. The defective migration was explained by the finding in serum from these patients of cell-directed inhibitory activity which was destroyed by heating (56 degrees C, 30 min). The B-lymphocytes as the origin of the inhibitory activity was suggested by the presence of a similar activity in supernatants from cultured tumour cells. 6 of the 18 patients had the combination of a defective chemokinetic activity and low levels of immunoglobulins. These 6 patients had an increased tendency towards infections.
