CCL19/CCL21-Dependent Chemotaxis of Dendritic Cells in Healthy Individuals and Patients with Brain Tumors

Abstract

We compared migration activities of IFN-α- and IL-4-induced dendritic cells (IFN-DC and IL4-DC) generated from blood monocytes of healthy donors and analyzed migration activity of IFN-DC from patients with brain tumors. In the presence of CCL19 chemokine, donor IFN-DC exhibited higher migration activity than IL4-DC, the expression of chemokine CCR7-receptor being similar in the two cell types. IFN-DC of patients with malignant gliomas were characterized by low chemotaxis in response to CCL19 and CCL21 stimulation despite a trend to higher expression of CCR7 in comparison with donor IFN-DC.
