Human IL1A encodes interleukin-1 alpha (IL-1α), a pro-inflammatory cytokine produced by epithelial and myeloid lineages that can act both as a membrane-associated ligand and as an alarmin released upon cell injury. IL-1α signals primarily through IL-1R1 to engage MyD88-dependent cascades that activate NF-κB and MAPK pathways, driving transcription of chemokines, adhesion molecules, and secondary cytokines. This axis contributes to leukocyte recruitment, fever and acute-phase responses, and coordinated remodeling of stromal and endothelial compartments during inflammation. Dysregulated IL-1α activity is implicated in chronic inflammatory conditions and tumor-associated inflammation, making IL1A a relevant node for dissecting cytokine networks and innate immune signaling.
IL-1α Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IL1A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IL1A. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt IL1A function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of IL1A-disrupted clones.
