Abstract excerpt
CD26, a surface serine dipeptidylpeptidase IV (DPPIV) expressed on different cell types, cleaves the amino-terminal dipeptide from some chemokines, including stromal-derived factor-1 (SDF-1/CXCL12). SDF-1/CXCL12 plays important roles in hematopoietic stem cell (HSC) homing, engraftment, and mobilization. Inhibition of CD26 peptidase activity enhances homing, engraftment, and competitive repopulation in congenic...
