In general, a virus'
core contains a matrix of proteins and genetic materials that keeps it intact, he says.
The two letters in the name stand for the two proteins that form the virus's
coating: Hemagglutinin and Neuraminidase The number to the right of each letter indicates which version of the protein the coating contains.
No treatment yet exists for Ebola or Marburg, but scientists have just identified a protein that may cause the Ebola virus's
grisliest symptom--massive bleeding.
For example, a few research teams at the NIH conference reported on how they have taken the HIV genes that code for particular proteins on the virus's
outer envelope and inserted them into the genetic machinery of E.
In one type of third-generation test, DNA probes use one side of the virus's
double helix to seek out its complementary half.
Determining the family to which the AIDS virus belongs is a question of more than academic interest: An understanding of the virus's
closest relatives could suggest a way to deal with the virus itself.
Whether the virus's
genetic diversity will affect the difficulty of developing an AIDS vaccine in unknown.
