Human IL13 encodes interleukin-13 (IL-13), a secreted type 2 cytokine that shapes immune responses by signaling through IL-13Rα1/IL-4Rα to activate JAK–STAT6 and downstream transcriptional programs. IL-13 promotes alternative macrophage polarization, goblet cell metaplasia, mucus production, and fibroblast activation, linking it to tissue remodeling and barrier inflammation. In hematopoietic and epithelial contexts, IL-13 intersects with Th2-associated networks and can modulate antigen presentation and chemokine expression. Dysregulated IL-13 signaling is implicated in allergic airway inflammation, asthma, atopic dermatitis, and fibrotic processes, making IL13 a useful node for mechanistic studies of type 2 immunity.
IL-13 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous IL13 expression without altering the underlying DNA sequence.
IL-13 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the IL13 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 IL13 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous IL-13 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native IL13 locus and enabling the study of IL-13-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of IL-13 pathway restoration in tumor cells with silenced or reduced IL13 expression.
