Expression and regulation of chemokine genes in the mouse uterus during pregnancy.
Leukocytes accumulate in the pregnant mouse uterus following mating, during implantation and during placental development. Changes in leukocyte number are primarily due to recruitment from the blood, not local proliferation, but the underlying recruitment mechanisms are poorly understood. Mating-induced granulocyte and macrophage recruitment is due in part to pro-inflammatory and chemotactic factors present in seminal plasma. Accumulation of macrophages later in pregnancy appears to be caused in part by ovarian hormone-stimulated CSF-1 production and in part by other as yet unidentified uterine chemotactic factors. The current study was performed to assess chemokine production in the uterus during pregnancy. Northern blotting was used to demonstrate NSI/KC (KC), macrophage chemotactic protein-1 (MCP-1), macrophage inflammatory protein one alpha (MIP1alpha) and regulated inactivation, normal T expressed and secreted protein (RANTES) mRNA in the uterus. Oestrogen and progesterone induced intrauterine production of all four chemokines and may have done so through the autocrine/paracrine activities of IL-1. The data suggest that C-C chemokines play a role in accumulation of macrophages in the uterus during pregnancy.
