Abstract: Cell adhesion molecules are critical to wound healing through leukocyte recruitment. Although P-selectin glycoprotein ligand-1 (PSGL-1) regulates leukocyte rolling by binding P-selectin, but also binding E- and L-selectins with lower affinity, little is known about a role of PSGL-1 in wound healing. To clarify a role of PSGL-1 and its interaction with E- and P-selectins in wound healing, we investigated cutaneous wound healing in PSGL-1-deficient (PSGL-1(-/-)) mice in comparison with E-selectin(-/-), P-selectin(-/-), and P-selectin(-/-) mice treated with an anti-E-selectin antibody. PSGL-1 deficiency inhibited early wound healing, which was accompanied by decreased inflammatory cell infiltration and growth factor expression. By contrast, E-selectin deficiency did not affect wound healing. In general, the inhibitory effect of PSGL-1 deficiency on wound healing was similar to that of P-selectin deficiency either alone or with E-selectin blockade. However, early granulation tissue formation, late angiogenesis, and early infiltration of neutrophils and macrophages in PSGL-1(-/-) mice were inhibited beyond the inhibition in P-selectin(-/-) mice, but to a similar level of inhibition in P-selectin(-/-) mice with E-selectin blockade. These results suggest that PSGL-1 contributes to wound healing predominantly as a P-selectin ligand and partly as an E-selectin ligand by mediating infiltration of inflammatory cells.
