Chemokines attract immune cells to sites of inflammation.1 In addition, chemokine signaling recruits neurons and other cells to specific sites during metastasis. The most conserved chemokine ligand/receptor signaling pathway is CXCL12/CXCR4/CXCR7.2 Therefore, the receptor CXCL12 has been produced as a new product at rPeptide and represents chemokines in the study of neurodegenerative diseases. Since chemokines have a role in inflammatory cell attraction, the function of neuroprotection in Alzheimer’s disease is an active area of investigation.
