Expression and Function of the Homeostatic Molecule Del-1 in Endothelial Cells and the Periodontal Tissue
Developmental endothelial locus-1 (Del-1) is an endothelial cell-secreted protein that limits the recruitment of neutrophils by antagonizing the interaction between the LFA-1 integrin on neutrophils and the intercellular adhesion molecule (ICAM)-1 on endothelial cells.Mice with genetic or age-associated Del-1 deficiency exhibit increased neutrophil
