Aim2 Knockout IBMDM Cell Line

The choice depends on whether you are studying AIM2 (absent in melanoma 2)'s role as a cytoplasmic dsDNA sensor and inflammasome scaffold or modeling its functions in innate immunity and emerging cancer applications. The Knockout line is the standard tool for asking whether AIM2 is required for these processes — AIM2 is a HIN-200 family cytoplasmic dsDNA sensor that detects bacterial, viral, and host genomic dsDNA, oligomerizing to assemble the AIM2 inflammasome with ASC/PYCARD and pro-caspase-1; AIM2 inflammasome activation drives IL-1β/IL-18 maturation and gasdermin D-mediated pyroptosis. Overexpression is useful for studying AIM2 gain-of-function effects. For innate immunity research, the EDITGENE Aim2 Knockout in IBMDM is highly relevant — IBMDM is an immortalized murine BMDM line, providing a physiologically relevant macrophage context for inflammasome research. Other AIM2-like receptors (IFI16, etc.) expression analysis aids interpretation. Rescue with wild-type or DNA-binding-deficient (HIN domain mutations) AIM2 enables structure-function studies. The knockout is valuable for studying cytoplasmic dsDNA sensing, AIM2 inflammasome biology in intracellular bacterial infections (Francisella, Listeria, Mycobacterium), and emerging AIM2 functions in cancer biology and DNA damage response.

Primary applications: • AIM2 inflammasome activation: dsDNA (poly-dA:dT) transfection-induced inflammasome activation analysis (IL-1β maturation, caspase-1 cleavage, GSDMD-N pyroptosis). • Intracellular bacterial infection: Francisella tularensis, Listeria monocytogenes infection-induced inflammasome activation. • ASC speck formation: ASC speck imaging in AIM2-null cells. • AIM2 inhibitor specificity: emerging AIM2 inhibitor specificity testing. EDITGENE recommends this IBMDM macrophage model for researchers investigating cytoplasmic dsDNA sensing and AIM2 inflammasome biology.

Yes. AIM2 rescue experiments are well-established for inflammasome research: • Construct design: use a codon-modified Aim2 sequence with a small C-terminal tag (FLAG, HA). AIM2 has N-terminal PYD (pyrin) domain (ASC binding) and C-terminal HIN-200 domain (dsDNA binding) — preserve all elements. • DNA-binding-deficient rescue: HIN domain mutations abolish dsDNA binding. • PYD-mutant rescue: PYD domain mutations disrupt ASC interaction. • Functional readout: rescue should restore dsDNA-induced inflammasome activation, IL-1β maturation, and ASC speck formation. IBMDM-specific considerations: • IBMDM is an immortalized murine bone marrow-derived macrophage cell line, providing a renewable myeloid context for innate immunity and inflammasome research. • Lentiviral transduction is supported with moderate efficiency. • Macrophage activation (LPS, IFN-γ priming) should be characterized before inflammasome and antimicrobial response assays.
