Interleukin-8 messenger RNA (CXCL8 mRNA) (IL-8 mRNA)

Interleukin-8 (IL-8) mRNA, also known as the CXCL8 gene transcript, is the precursor molecule required for the production of the IL-8 protein, a potent pro-inflammatory chemokine and neutrophil chemoattractant (NCBI Gene, 2024). The expression of this mRNA is tightly regulated but can be rapidly upregulated in response to inflammatory stimuli such as TNF-alpha, IL-1, and various pathogens, playing a critical role in the recruitment of immune cells to sites of infection or injury (PubMed, 2022). In pathological contexts, such as chronic obstructive pulmonary disease (COPD), psoriasis, and various cancers, the overproduction of IL-8 mRNA leads to excessive neutrophil infiltration and promotes tumor growth, angiogenesis, and metastasis (Nature Reviews Cancer, 2021). As a therapeutic target, IL-8 mRNA is primarily addressed using RNA-based technologies, including small interfering RNAs (siRNAs) and antisense oligonucleotides (ASOs), which are designed to bind specifically to the transcript and trigger its degradation or block its translation (Molecular Therapy, 2020). By silencing the gene at the mRNA level, these therapies aim to reduce the overall burden of the IL-8 protein more effectively than traditional inhibitors, potentially offering a more durable therapeutic effect in inflammatory and oncological diseases (Journal of Controlled Release, 2019). However, challenges remain regarding the targeted delivery of these nucleic acid drugs and the potential for off-target effects or unintended immune activation (Frontiers in Pharmacology, 2021).
