To explore the potential of developing a plant-based vaccine, a plant optimized gene encoding Narita 104 virus capsid protein (NaVCP) was expressed transiently in Nicotiana benthamiana using a tobacco mosaic virus expression system.
One method used to express high levels of protein in plants involves the employment of plant virus expression vectors.
To confirm virus expression of HA-SSTR2, HT1080 cell lines were used.
Plant virus expression vectors have the ability to either overexpress genes or suppress gene expression in plants.
This review describes the current design and status of plant virus expression vectors used as production platforms for biopharmaceutical proteins.
The non-structural proteins encoded by the orf-I, II, III, and IV genes of the human T-cell leukemia/lymphoma virus type 1 (HTLV-1) genome, are critical for the modulation of cellular gene expression and T-cell proliferation, the escape from cytotoxic T-cells and natural killer cells, and virus expression.
This is attributed to persistent virus expression in reservoirs and to cell activation.
Histone deacetylase inhibitors could lead to virus expression without full cell activation [29] (see above).
Alternative therapies are sorely needed in this disease that simultaneously prevent virus expression, and are cytocidal for malignant cells.
Virus expression was scored by immunofluorescence and only cultures showing a percentage of infection over 70% were further processed.
Of interest, recent reports suggested that histone deacetylase inhibitors could lead to virus expression without full cell activation [29].
