Tag-7 Gene-modified Vaccine

**Semantic type:** Immunologic Factor|Pharmacologic Substance

**Definition:** A cell-based vaccine composed of autologus inactivated tumor cells that have been genetically modified with the gene encoding for the innate immunity protein peptidoglycan recognition protein 1 (Tag7; PGRP-S; PGLYRP1; TAG-7), with potential immunomodulating and antineoplastic activities. Upon subcutaneous administration of Tag-7 gene-modified vaccine (GMV), the Tag-7 transfected tumor cells express Tag-7 which is presented to the immune system and activates the innate immune system. This may activate the immune system to exert a T-lymphocyte-mediated immune response against Tag-7-expressing tumor cells.

**Synonyms:** - GMV - Tag-7 GMV - Tag-7 Gene-modified Inactivated Tumor Cell Vaccine - Tag7 Gene-modified Inactivated Tumor Cell Vaccine
