IL-8 Gene Editing    

Interleukin 8 (IL-8), or chemokine (C-X-C motif) ligand 8 (CXCL8 gene, encoding the interleukin-8 protein), also known as neutrophil chemotactic factor, is initially produced as a precursor peptide of 99 amino acids which then undergoes cleavage to create several active IL-8 isoforms. IL-8 is produced by macrophages, which secrete a 72 amino acid peptide, the major form of those active IL-8 isoforms, and other cell types, such as airway smooth muscle cells, epithelial cells and endothelial cells. CXCR1and CXCR2 are the most frequently studied GPCRs types on the surface membrane capable of binding IL-8, with different binding affinity and expressing level, and promotes the recruitment of immunosuppressive MDSCs (myeloid-derived suppressor cells). IL-8 plays a key role in inducing the cell signaling necessary to bring about these changes, such as recruitment of neutrophils to the site of damage or infection, stimulating phagocytosis and promoting angiogenesis.

Role of IL-8 in cancer

It has been found that tumors very frequently coopt the production of this chemokine, which exerts different pro-tumoral functions. Both tumor and tumor-associated stromal cells can upregulate production of IL-8, causing MDSCs to migrate to the tumor microenvironment where they suppress the antitumor immune response, locally provide growth factors and expand the stroma. Reportedly, these include angiogenesis, which has been mentioned above, and survival signaling for cancer stem cells. Given the fact that in cancer patients IL-8 is mainly produced by tumor cells themselves, its serum concentration has been shown to correlate with tumor burden. Thus, IL-8 serum concentrations have been shown to be useful pharmacodynamic biomarker to early detect response to immunotherapy. Since the roles that IL-8 plays in favoring tumor progression, inhibition of IL-8 may reduce these tumorigenic effects. Several therapeutic strategies have been developing to interfere with its functions. Such interventions hold promise, especially for therapeutic combinations in the field of cancer immunotherapy.
