Transient expression of foreign genes based on plant viral vectors is a suitable system for the production of relevant immunogens that can be used for the development of a new generation of vaccines against a variety of infectious diseases. In the present study the epitope derived from HPV-16 L2 minor capsid protein (amino acids 108–120) was expressed from(More)
Potato virus X (PVX) is widely used as a peptide presentation system in plant biotechnology, mostly by fusion of desired peptides to the N-terminus of its capsid protein (CP). Considering that some epitopes can interfere with the stability and/or self-assembly of PVX CP when fused to its N-terminus, we evaluated four other possible sites for fusion using(More)
The Potato virus X (PVX)-based vector was used for the construction of N- and C-terminally modified PVX coat protein (XCP) chimeras. N-terminal XCP modifications do not influence the viral life cycle, whereas the simple XCP C-terminal fusion impedes the viral replication. We designed several C-terminally modified XCP chimeras and tested their viabilities in(More)
Infection with Human papillomaviruses (HPVs) is linked to cervical cancer, which is one of the most common cancers found among women worldwide. Despite preventive immunization, a therapeutic vaccine, targeting infected individuals, is required. Vaccine strategies for treatment of HPV—induced cervical cancer are based on E7 and E6 oncoproteins. In this work(More)
The use of light emitting diodes (LEDs) brings several key advantages over existing illumination technologies for indoor plant cultivation. Among these are that LEDs have predicted lifetimes from 50–100.000 hours without significant drops in efficiency and energy consumption is much lower compared to traditional fluorescent tubes. Recent advances allow LEDs(More)
Within the last two decades, plant viral vectors have emerged as an excellent tool for the expression of foreign peptides and proteins. Virus particles carrying foreign antigenic epitopes present some interesting advantages for vaccine design and other applications. This review covers recent advances in the use of some typical plant viruses with helical(More)
We employed the comet assay (single cell gel electrophoresis) to evaluate induced DNA damage in nuclei isolated from tobacco leaves (Nicotiana tabacum var. xanthi) inoculated with Potato virus X (PVX). The highest DNA damage, expressed by the tail moment value, was observed in the inoculated leaves and decreased in the 1st to 4th systemic leaves. DNA damage(More)
