Nlrc4 Knockout IBMDM Cell Line

The choice depends on whether you are studying Nlrc4's role as the central NLR family inflammasome platform sensing bacterial flagellin and type III secretion system components or modeling autoinflammation with infantile enterocolitis (AIFEC) syndrome. The Knockout line is the standard tool for asking whether Nlrc4 is required for these activities — Nlrc4 inflammasome assembly is triggered by NAIP family co-receptor recognition of bacterial flagellin (NAIP5/6), type III secretion needle (NAIP1), or rod (NAIP2) proteins from Salmonella, Legionella, Burkholderia, and other intracellular pathogens. Overexpression is useful for studying Nlrc4 in heterologous expression contexts or for testing AIFEC-associated gain-of-function mutations. For macrophage innate immunity research, the EDITGENE Nlrc4 Knockout in IBMDM is uniquely valuable — IBMDM preserves authentic macrophage inflammasome responses to bacterial infection. Rescue with wild-type or AIFEC-associated activating mutant (e.g., V341A, T337S) Nlrc4 enables comprehensive disease modeling — AIFEC patients have severe infantile autoinflammation and infectious susceptibility. The knockout is critical for studying gasdermin-D-mediated pyroptosis downstream of Nlrc4 activation.

Primary applications: • Inflammasome activation: ASC oligomerization, caspase-1 cleavage, and IL-1β/IL-18 release following Salmonella infection or flagellin/needle/rod protein cytosolic delivery. • Bacterial pathogen restriction: intracellular Salmonella, Legionella, or Burkholderia replication assays given Nlrc4's role in restricting these pathogens. • NAIP co-receptor studies: NAIP1 (needle), NAIP2 (rod), NAIP5/6 (flagellin) co-receptor requirement for Nlrc4 activation. • AIFEC modeling: rescue with patient-derived activating Nlrc4 mutations (V341A, T337S) for genotype-function studies of infantile autoinflammation. EDITGENE recommends this model for researchers investigating bacterial inflammasome activation, macrophage innate immunity, and AIFEC-related autoinflammatory disease mechanisms.

Yes. Nlrc4 rescue experiments are well-established for inflammasome research: • Construct design: use a codon-modified Nlrc4 sequence with a small C-terminal tag (FLAG, HA). Nlrc4 has N-terminal CARD, NACHT domain, and C-terminal LRR — preserve all elements. • NAIP co-receptor partnership: Nlrc4 activation requires NAIP co-receptor recognition of bacterial ligands — rescue interpretation considers NAIP expression in IBMDM. • AIFEC mutation rescue: gain-of-function Nlrc4 mutations (V341A, T337S) enable disease genotype-function studies of infantile autoinflammation. • Functional readout: rescue should restore Salmonella-induced or flagellin-induced caspase-1 activation, IL-1β/IL-18 release, and pyroptosis. IBMDM-specific considerations: • IBMDM are immortalized murine bone marrow-derived macrophages — a primary-cell-like immune background that preserves canonical macrophage signaling. • Lentiviral transduction efficiency is moderate compared to standard cell lines; spinoculation and increased MOI may be required for rescue line generation. • Macrophage activation state can vary — characterize basal polarization (M1/M2 markers) before phenotypic assays.
