Résumé
Interleukin-1alpha (IL-1alpha) is a multifunctional cytokine that stimulates myelopoiesis in macaque. However, daily systemic injections of IL-1alpha are associated with severe side effects. We therefore investigated the feasibility of a gene therapy strategy aimed at increasing the IL-1alpha local production in bone marrow with limited release of the vector into the blood circulation. Intra-medullar administration of adenoviral vector containing human IL-1alpha (huIL-1alpha) gene resulted in enhanced neutrophil, monocyte and platelet counts during the two first weeks after injection. The DNA vector, the transgene expression and the huIL-1alpha production was detected in treated bone marrow without significant detection of huIL-1alpha in the peripheral blood. Associated with huIL-1alpha production, we observed concomitant plasma C reactive protein and IL-1Ra peaks in the acellular fraction of treated bone marrow at days 3 and 7. No abnormal clinical side effects were observed in any of the animals following the adenoviral vector injection.
