Vaccination against influenza from tobacco plants virus
At a recent Conference, Dr. Louis Philippe (Quebec), Medicago company presented a new system to produce vaccines. Relies on plant Nicotiana benthamiana that is they inoculated with the virus (of any type of influenza) and generate a similar to the virus, which resembles the influenza virus but contains the genetic material of the virus particle. Produces a virus, but hollow, serving as a vaccine. The great advantage of this system is that, unlike traditional systems use eggs to produce vaccines, is much faster.
Remedies and services for pandemics market is enormous, moved to year 7 billion dollars. This technology may also produce other remedies called biosimilares (for cancer and other diseases); it is estimated that the biosimilares market will amount to $ 50 billion in 2017.
Medicago Inc. is a biotechnology company focused on the development of effective vaccines and based on their similar viruses (VLPs) and manufacturing technologies particles reduced cost. It has developed VLP vaccine to protect against pandemic H5N1 virus using a transient expression system that produces recombinant vaccine antigens in not transgenic plants. This technology has the potential to offer the advantages of speed and cost versus competitive technologies. It can provide a vaccine for testing in a month after their identification and reception of genetic sequences to a variant of the pandemic. This production time frame has the potential to allow vaccination of the population before the first wave of attacks of pandemic, supplying a large volume of antigens of the vaccine to the world market.
Viruses of plants to fight HIV
In a study which would be on the verge of getting new ways to prevent infection with HIV and other similar viruses, Purdue University researchers have genetically modified plant to stop the playback of a related viruses.
After HIV infects the person, you must lock certain particular proteins to reproduce in the body, says Zhixiang Chen, Professor of Botany and plant pathology "we found that the Cauliflower mosaic virus uses the same method to multiply in plants". Known as CaMV, mosaic virus attacks a group of plants including cauliflower, broccoli, turnips, cabbages, canola and many types of mustard. We believe that these proteins in plants could be of particular importance for this type of virus, such as HIV, since blocked viruses not may replicate simply".
