Human peripheral blood lymphocytes were surface stained with Alexa Fluor® 647 rat IgG2b, κ isotype control (Cat. No. 400626) (left panel), Alexa Fluor® 647 anti-human CD195 (CCR5) (Cat. No. 359114) (middle panel), or with AZDye 647 Recombinant Human CCL5 (right panel). -
Biological activity was performed in HEK293T cells expressing human CCR5 by measuring its ability to recruit β-arrestin2. The ED50 for this effect was calculated at 8 to 30 ng/mL.

CCL5, also known as RANTES, is a CC chemokine that directs the migration of leukocytes in immune and inflammatory responses. Increased CCL5 expression has been associated with a wide range of inflammatory disorders and pathologies. It has been shown that CCL5 is highly expressed by breast tumor cells at primary tumor sites and is strongly associated with the progression of breast cancer. CCL5 may contribute to tumor progression by recruiting monocytes into tumor sites, and CCL5 can also stimulate the release of MMP, thereby promoting tumor cell migration. Some studies also show that CCL5 has pro-angiogenesis effects in vivo and in vitro. CCL5 oligomerization and binding to GAGs can induce angiogenic effects through its receptor CCR1 and CCR5. CCL5 is expressed in the early stages of many viral infections. It has been shown that CCL5 is protective against many viruses including influenza, RSV, HCMV, HCV, and HIV. CCL5 can inhibit HIV infection by competing with the virus for CCR5 binding. CCL5 also has been implicated in the development of asthma, atherosclerosis, and fibrosis.

Antigen Details
- Structure
- CCL5 is a 68 amino acids molecule with a predicted molecular weight of 7.8 kDa. PDB ID – 1B3A
- Distribution
-
CCL5 is secreted by lymphocytes, macrophages, eosinophils, platelets, and fibroblasts. CCL5 is expressed by hepatocytes, sinusoidal endothelial cells and biliary epithelium during chronic hepatitis C
- Function
- CCL5 can promote IL-2 and IL-5 expression in human T cells, and the expression of IL-6 and IL-8 in fibroblasts from patients with RA. CCL5 modulates LPS-induced IL-6 and TNFα in peripheral blood monocytes; this modulation occurs through the induction of IL-10 by CCL5.
- Interaction
- CCL5 is a chemoattractant for memory and activated T cells, monocytes, dendritic cells, eosinophils, NK cells, mast cells, and basophils
- Ligand/Receptor
- CCL5 binds to CCR1, CCR3, and CCR5 receptors. CCL5 also binds to CCR9 but does not induce calcium flux, and therefore there is no chemotactic response.
- Bioactivity
- Measured by its ability to recruit β-arrestin 2 in HEK293T cells transfected with human CCR5. The ED50 for this effect was measured at 8 to 30 ng/mL.
- Cell Type
