C-C chemokine ligand 5 (CCL5), also known as RANTES, is a target gene of NF-kappaB, and is expressed by T lymphocytes, macrophages, platelets, synovial fibroblasts, tubular epithelium, and certain types of tumour cells [PMID: 18439751, PMID: 24523569]. CCL5 plays a role in recruiting a variety of leukocytes into inflammatory sites including T cells, macrophages, eosinophils, and basophils. CCL5 activity is mediated through its binding to CCR1, CCR3, and mainly CCR5 [PMID: 16791620, PMID: 18439751].
CCR5 is a G-protein-coupled receptor for CCL3, CCL4 and CCL5. CCR5 is also the major coreceptor for HIV-1 entry into target cells and is thought to be a suitable therapeutic target for HIV-1 blockade [PMID: 24855645]. However, the affinity between CCR5 and natural CCL5 is low and has limited viral entry inhibiting activity. Therefore, several CCL5 derivatives with high anti-HIV-1 potency have been produced to act as entry inhibitors and CCR5 antagonists [PMID: 25114130, PMID: 18243436].
