Biological Activity

Description Leronlimab (anti-CCR5) （PRO 140; Vyrologix）is a humanized monoclonal antibody to CCR5, blocks breast cancer cellular metastasis and enhances cell death induced by DNA damaging chemotherapy. It is being investigated as a potential therapy in the treatment of HIV infection.
In vitro

Leronlimab binds CCR5 in multiple breast cancer cell lines, reducing ligand-induced Ca+ 2 signaling, invasion of TNBC into Matrigel, and transwell migration, also enhances the breast cancer (BCa) cell killing of the BCa chemotherapy reagent, doxorubicin.[1]
In vivo

In xenografts conducted with Nu/Nu mice, leronlimab reduces lung metastasis of the TNBC cell line, MB-MDA-231, reducing the metastatic tumor burden of established TNBC lung metastasis.[1]

Protocol (Only for Reference)

Cell Assay:

  • Equal numbers of cells were plated, and after 72 h of exposure to the drugs, cells were incubated with 1 mg/mL of MTT for 90 min. The reduced (insoluble and colored) formazan was dissolved in 0.04 N HCl acidified isopropanol and measured spectrophotometrically at 570 nm.
Animal Study:

  • AnimalModels:Female NCI Athymic nu/nu nude mice injected with MB-MDA-231 cells expressing Luc2-eGFP
    Dosages:2 mg/mouse
    Administration:i.p.[1]
