Abstract
Hemokinin 1 is encoded by preprotachykinin C (PPT-C) mRNA, and has been proposed as a regulator of B and T cell lymphopoiesis. Here we demonstrate the expression of mouse PPT-C mRNA by CD11b+ macrophages, CD11c+ dendritic cells and in the microglial cell line EOC 13.31. Expression was detected in freshly isolated CD11b+CD11c+ bone marrow cells, as well as in M-CSF expanded bone marrow-derived macrophages and GM-CSF expanded bone marrow-derived dendritic cells. There was preferential expression of PPT-C mRNA in dendritic cell subpopulations that were CD11b+, but not B220+ or GR-1+. These studies are the first to demonstrate PPT-C mRNA expression by cells of the myeloid lineage. Copyright 2004 Elsevier B.V.Entities:
