GM-CSF-encoding oncolytic herpes simplex virus

Definition / meaning of GM-CSF-encoding oncolytic herpes simplex virus

An oncolytic, recombinant herpes simplex type-1 virus (HSV) encoding thuman cytokine granulocyte-macrophage colony stimulating factor (GM-CSF) with potential immunostimulating and antineoplastic activities. Upon administration, GM-CSF-encoding oncolytic HSV selectively infects and replicates in tumor cells, thereby inducing tumor cell lysis. In addition, expressed GM-CSF may stimulate a cytotoxic T cell response against tumor cells, resulting in immune-mediated tumor cell death in addition to HSV-mediated oncolytic tumor cell death.
