The herpes simplex virus type 1 (HSV-1) latency associated transcript (LAT) gene has anti-apoptosis activity that directly or indirectly enhances the virus’s reactivation phenotype in small animal models. The first 1.5 kb of the primary 8.3 kb LAT is sufficient and some or all of it is necessary for LAT’s anti-apoptosis in transient transfection assays and for LAT’s ability to enhance the reactivation phenotype. Based on LAT’s genomic sequence, the first 1.5 kb contains eight potential open reading frames (ORFs) defined as an ATG followed by an in frame termination codon. In this study, point mutations were introduced into the …
Comparative Roles Of Herpes Simplex Virus Type 1 (Hsv-1) Glycoproteins In Cytoplasmic Virion Egress, Hyuncheol Lee
Comparative Roles Of Herpes Simplex Virus Type 1 (Hsv-1) Glycoproteins In Cytoplasmic Virion Egress, Hyuncheol Lee
LSU Master's Theses
HSV-1 acquires its final envelope by budding into cytoplasmic vesicles thought to be derived from Trans-Golgi Network (TGN) membranes. This process is facilitated by interactions among the carboxyl termini of viral glycoproteins and tegument proteins. To investigate the relative importance of different viral glycoproteins in cytoplasmic virion morphogenesis, a set of recombinant viruses were constructed silencing expression of the glycoprotein E (ΔgE), the carboxyl terminus of glycoprotein D (gDΔcp), and the membrane protein UL20 (ΔUL20). In addition, recombinant viruses were constructed having the ΔgE+gDΔcp, and the ΔgE+ΔgM (glycoprotein M) deletions. These recombinant viruses were constructed using the double-red, site-directed mutagenesis …

Oncolytic herpes simplex virus type-1 (HSV-1) has shown great potential as an effective agent for cancer therapy ¨C oncolytic virotherapy. To enhance oncolytic capabilities of previously reported agents, new oncolytic and fusogenic HSV-1 OncSyn and OncdSyn viruses were constructed based on wild type HSV-1 (F) strain. To provide for safety and tumor selectivity, the viruses carried a large deletion including one of the two ¦Ã134.5 genes. The ¦Ã134.5 gene, a major neurovirulence factor, was replaced by a gene cassette constitutively expressing the red fluorescent protein. Homologous recombination was utilized to transfer the fusogenic gBsyn3 mutation to the viral genome to …
