  • Recombinant human IL-8 (HZ-1318) stimulates dose-dependent proliferation of the THP-1 human monocyte cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. THP-1 cells were treated with increasing concentrations of recombinant IL-8 for 144 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 100-500 ng/mL.

Background

IL-8 is a chemoattractant cytokine that signals through the CXCR1 and CXCR2 receptors to attract and activate neutrophils to sites of inflammation. It is secreted by multiple types of cells, including monocytes, neutrophils, tumor, epithelial, endothelial, and fibroblasts. IL-8 signaling activates downstream pathways that promote cell survival, proliferation, and cell invasiveness. As such, IL-8 has been linked to the promotion of angiogenesis, immunosuppressive cell recruitment, and EMT transition in several cancer types. Recent studies also indicate that IL-8 can serve as a marker for COVID-19 disease progression (PMID: 22235381, 18980965, 26548401, 33584733).
