On the cover: Dual immunofluorescence of decidua basalis: macrophages CD163⁺ (green) express CCR1 receptor (red). CCR1 is a receptor for the chemokine CCL14 and this interaction may be important in regulating leukocyte infiltration into spiral arterioles during early remodeling. Choudhury, R. H., C. E. Dunk, S. J. Lye, J. D. Aplin, L. K. Harris, and R. L. Jones. 2017. Extravillous trophoblast and endothelial cell crosstalk mediates leukocyte infiltration to the early remodeling decidual spiral arteriole wall. J. Immunol. 198: 4115–4128.
