NLRP3 Human shRNA Lentivirus

NOD, LRR and pyrin domain containing 3 (NLRP3), also known as NALP3 and cryopyrin, is a pattern recognition receptor (PRR) of the NRL (NOD-like receptor) subfamily. It is involved in the detection of microbes, endogenous and exogenous stress signals. It is expressed in macrophages and when bound to PYCARD (adaptor ASC protein) forms a caspase-1 activating complex named NRLP3 inflammasome. NLRP3 detects uric acid and extracellular ATP in damaged cells, and once activated it leads to an immune response. Upon activation, NLRP3 inflammasome releases its partners HSP90 and SGT1, and binds to PYCARD and caspase-1. Caspase-1 initiates the processing and release of the pro-inflammatory cytokines IL-1β and IL-18 and gasdermin D-mediated pyroptotic cell death. Mutations in NLRP3 are known to cause autoinflammatory and neuroinflammatory diseases, such as Alzheimer’s, Parkinson’s, and prion disease. NLRP3 is the most extensively studied inflammasome protein to date due to its array of activators and aberrant activation in several inflammatory diseases. Studies into its function and inhibition can lead to the development of therapeutic avenues for the treatment of auto-inflammatory diseases.

Lentiviruses are shipped with dry ice. For long-term storage, it is recommended to store the lentiviruses at -80°C for up to 12 months from date of receipt. Avoid repeated freeze/thaw cycles. Titers can drop significantly with each freeze/thaw cycle.

To generate a NLRP3 knockdown stable cell line, remove the growth medium 48 hours after transduction and replace it with fresh growth medium containing the appropriate amount of puromycin (as pre-determined from a killing curve, https://bpsbioscience.com/cell-line-faq), for antibiotic selection of transduced cells, following by clonal selection.BiosafetyThe lentiviruses are produced with a SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and after integration into the genomic DNA of the target cells. None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal and are not present in the lentivirus particle. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.Troubleshooting GuideVisitbpsbioscience.com/lentivirus-faqfor detailed troubleshooting instructions.

The lentivirus particles were produced from HEK293T cells in medium containing 90% DMEM + 10% FBS. Virus particles can be packaged in custom formulations by special request, for an additional fee.
