Mouse Il1b encodes interleukin‑1 beta (IL‑1β), a potent pro‑inflammatory cytokine produced primarily by activated myeloid cells and processed into its mature form following inflammasome‑dependent caspase‑1 cleavage. IL‑1β signaling through IL‑1 receptor complexes drives NF‑κB and MAPK pathway activation, promoting transcription of chemokines, adhesion molecules, and additional cytokines that coordinate leukocyte recruitment and innate immune amplification. This axis is tightly linked to pyroptosis, fever responses, and crosstalk with TNF and IL‑6 networks, shaping tissue inflammation and remodeling. Dysregulated IL‑1β production is widely used as a molecular readout in mouse models of infection, autoimmune and autoinflammatory syndromes, metabolic inflammation, and neuroinflammatory processes.
IL-1 beta/IL1B Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Il1b locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Il1b. 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 Il1b 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 Il1b-disrupted clones.
