Human IL17A encodes IL-17A (IL-17), a pro-inflammatory cytokine predominantly produced by Th17 cells and other innate-like lymphocytes that amplifies tissue immune responses. IL-17A signals through the IL-17RA/IL-17RC receptor complex to activate ACT1/TRAF6-dependent cascades, driving NF-κB, MAPK, and C/EBP transcriptional programs that promote chemokine production and neutrophil recruitment. This axis coordinates host defense at barrier sites and shapes crosstalk with IL-23/STAT3 and TNF pathways to regulate inflammatory gene networks. Dysregulated IL-17A activity is frequently studied in models of chronic inflammation and autoimmunity, including psoriasis-like skin inflammation, inflammatory bowel disease, and airway inflammatory responses.
IL-17 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous IL17A expression without altering the underlying DNA sequence.
IL-17 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the IL17A locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the IL17A transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous IL-17 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native IL17A locus and enabling the study of IL-17-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of IL-17 pathway restoration in tumor cells with silenced or reduced IL17A expression.
