Possible Treatment For Ebola

RedEaredSlider writes "Researchers at the US Army Medical Research Institute of Infectious Diseases have found a class of drugs that could provide treatment for Ebola and Marburg hemorrhagic fever. The new drugs are called 'antisense' compounds, and they allow the immune system to attack the viruses before they can do enough damage to kill the patient. Travis Warren, research scientist at USAMRIID, said while the work is still preliminary -— the drugs have been tested only on primates — the results are so far promising. In the case of Ebola, five of eight monkeys infected with the virus lived, and with Marburg, all survived. The drugs were developed as part of a program to deal with possible bioterrorist threats, in partnership with AVI Biopharma."

Oligos aren't too expensive, have a long shelf life (for my applications anyway) and when dehydrated can be stored at room temperature for quite a while. If antisense therapy works for a wide variety of viruses, it could make sense for large cities and major international airports to have a "toolkit" of antisense oligos ready to go for a variety of outbreaks, and this wouldn't be too expensive to maintain. If ebola entered the network of airports and large outbreaks started, you could have the therapy right there. Influenza? Same thing.

Furthermore, we know that a wide swathe of mammals (from rodents to bats to marsupials) carry 'fossil' Filovirus genetic material in their genomes, meaning that at least their ancestors were carriers of these viruses. Still further, Ebola and Marburg are part of the order Mononegavirales. This order contains the viruses that cause rabies, measles, mumps, and Newcastle disease (a really nasty scourge of domestic and wild birds). It's certainly possible that this treatment, as it undergoes further development, could be applied to related diseases.
