Production and characterization of novel Anti-HIV Fc-fusion proteins in plant-based systems: Nicotiana benthamiana & tobacco BY-2 cell suspension.

Multifunctional anti-HIV Fc-fusion proteins aim to tackle HIV efficiently through multiple modes of action. Although results have been promising, these recombinant proteins are hard to produce. This study explored the production and characterization of anti-HIV Fc-fusion proteins in plant-based systems, specifically Nicotiana benthamiana plants and tobacco BY-2 cell suspension.

Physicochemical characterization of the recombinant lectin scytovirin and microbicidal activity of the SD1 domain produced in rice against HIV-1.

Rice-produced SD1 retains its physicochemical properties and provides efficient pre-exposure HIV-1 prophylaxis against infection in vitro. Scytovirin (SVN) is an HIV-neutralizing lectin that features two structural domains (SD1 and SD2) that bind to HIV-1 envelope glycoproteins. We expressed SD1 in rice seeds as a potential large-scale production platform and confirmed that rice-derived SD1 binds the HIV-1 envelope glycoprotein gp120 in vitro.

Contributions of the international plant science community to the fight against human infectious diseases - part 1: epidemic and pandemic diseases.

Infectious diseases, also known as transmissible or communicable diseases, are caused by pathogens or parasites that spread in communities by direct contact with infected individuals or contaminated materials, through droplets and aerosols, or via vectors such as insects. Such diseases cause ˜17% of all human deaths and their management and control places an immense burden on healthcare systems worldwide. Traditional approaches for the prevention and control of infectious diseases include vaccination programmes, hygiene measures and drugs that suppress the pathogen, treat the disease symptoms or attenuate aggressive reactions of the host immune system.
