This product is a GM-CSF expressing oncolytic herpes simplex virus, which is based on HSV-1 with ICP6 and two copies of ICP34.5 deleted. ICP6 encodes a viral ribonucleotide reductase (vRR) function that allows replication of wild-type HSV to occur even in quiescent cells, such as the neurons. ICP34.5 protein, is important for viral replication, viral exit from infected cells, prevention of the premature shut-off of protein synthesis in the infected host, and neurovirulence. This product can be used in oncolytic virotherapy research and further recombinant HSV construction.

Backbone Background
Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. Modified Herpes simplex virus is considered as a potential therapy for cancer and has been extensively clinically tested to assess its oncolytic ability.
Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine. The pharmaceutical analogs of naturally occurring GM-CSF are called sargramostim and molgramostim. Unlike granulocyte colony-stimulating factor, which specifically promotes neutrophil proliferation and maturation, GM-CSF affects more cell types, especially macrophages and eosinophils.
