Infection of Nicotiana benthamiana Plants with Potato Virus X (PVX)
[Abstract]  Potato Virus X (PVX) is the type member of Potexvirus genus, a group of plant viruses with a positive-strand RNA genome (~6.4 kb). PVX is able to establish compatible infections in Nicotiana benthamiana, a commonly used host in plant virology, leading to mild symptoms, such as chlorotic mosaic and mottling. PVX has been widely used as a viral vector for more than two decades (Chapman et al., 1992; Baulcombe et al., 1995; Aguilar et al., ...

INF-gamma Release ELISpot Assay
[Abstract]  IFN-γ (Interferon-gamma) is produced mainly by activated T cells and NK cells. Production of IFN-γ (Interferon-gamma) by helper T cells as well as cytotoxic T cells is a hallmark of the TH1-type phenotype, thus, high-level production of IFN-γ (Interferon-gamma) is typically associated with effective host defense against intracellular pathogens. The Enzyme-Linked ImmunoSpot (ELISpot) assay is commonly used to assess the function of antigen specific T cells by detecting IFN-γ release. The ELISpot ...
