IL-7-expressing Oncolytic Vaccinia Virus Western Reserve (ΔE3L,ΔK3L), p7.16k-(IL-7)(Cat#: CyOV-0177WQ)

This product is a IL-7 encoding oncolytic vaccinia virus, which is based on VACV-WR with E3L and K3L double deleted.Protein E3 plays a role in the inhibition of multiple cellular antiviral responses activated by dsRNA, such as inhibition of PKR activation, apoptosis, and IFN-mediated antiviral activities. Protein K3 acts as a pseudosubstrate for EIF2AK2/PKR kinase. Inhibits therefore eIF-2-alpha phosphorylation by host EIF2AK2/PKR kinase and prevents protein synthesis shutoff.The double deletion of E3L and K3L with oncolytic-rendered modifications could enhance an immune response to a poxvirus vaccine.This product can be used in oncolytic virotherapy research and vaccinie application.

Information

Introduction The protein encoded by this gene is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. This cytokine is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRB) during early T cell development. This cytokine can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes. Knockout studies in mice suggested that this cytokine plays an essential role in lymphoid cell survival. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional splice variants have been described but their presence in normal tissues has not been confirmed.
