The effects of cyclic 3′, 5′‐AMP (cAMP) and cyclic 3′, 5′‐GMP (cGMP) on the in vitro migration of human peripheral blood leucocytes under agarose and on the activity of leucocyte migration inhibitory factor (LIF) was studied. Leucocyte migration was not influenced by dibutyryl cAMP, while the dibutyryl derivative of cGMP significantly stimulated cell migration (1 times 10 ‐5 M). LIF‐treated leucocytes partially escaped migration inhibition in the presence of dibutyryl cAMP (1 times 10 ‐6 M), while dibutyryl cGMP was inefficient. If the parent compounds cAMP and cGMP were tested, almost similar results would be obtained, although at higher concentrations of the drugs. These results represent initial experiments with a view to investigating the possible rôle of cyclic nucleotides in the expression of LIF activity.
