A lot of my blog posts recently have been on viruses since this is where my main scientific interests lie (and much of my knowledge). However, there’s so much more out there in science and not everyone is as interested in virology as I am, so I like to mix it up where possible. I had originally intended this post to have nothing to do with viruses, but then an article caught my eye. I’ve now postponed leaving the virological topics, for a little while, to talk about a new discovery because I think it’s very cool.

with my explanation in the text, but I do want to point out that the
virus does not infect the same cell it has come from as this would imply
|An image of tetherin in action. Taken directly from Neal et al. Nature 451 (2008) - the paper that had the original discovery of the protein. The main image to look at is the box labelled G, the small black dots are HIV particles, and the big grey bulge is the cell. You can see that tetherin is holding HIV particles to the cell and blocking their escape.|
