IL-15 Lentiviral Activation Particles (m) | sc-421089-LAC | 200 µl | $455.00 |
Mouse Il15 encodes interleukin-15 (IL-15), a pleiotropic cytokine that supports development, survival, and activation of NK cells and memory CD8+ T cells through IL-15Rα–mediated transpresentation to IL-2/15Rβ and common γ-chain receptor complexes. Downstream signaling prominently engages JAK1/JAK3-STAT5, with additional contributions from PI3K–AKT–mTOR and MAPK pathways that shape lymphocyte proliferation, cytotoxic function, and metabolic fitness. IL-15 also influences myeloid cell activation and cytokine networks within inflamed tissues, linking innate and adaptive immune responses. Dysregulated IL-15 expression and signaling are widely studied in contexts of chronic inflammation, autoimmunity, infection, and tumor immunology as a driver of altered immune cell composition and activation state.
IL-15 Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Il15 upregulation across a broader range of human cell types.
IL-15 Lentiviral Activation Particles (m) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the Il15 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous IL-15 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Il15 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
