Fig. 7.
Chemokine receptors important in leukocyte trafficking pathways. Arrows demarcate major leukocyte traffic routes between major tissue and hematopoietic compartments. Cells along the arrows identify some of the cells that follow these routes. The receptors listed for each cell either mark the cell or are used by the cell for trafficking on the route shown. Abbreviations: HSC, hematopoietic stem cell; Tem, effector memory T cell; Teff, effector T cell; Tdp, double positive thymocytes; Tsp, single positive thymocytes; TFH, follicular help T cells.
