    Fascinating.... A teamwork mechanism in a virus. A very interesting discovery.

"BTW...CBC people are coming in for an interview and they want a video/pictures of the mechanism." lol! So I was in a pickle and made this in the bus ride back to parents house on the old laptop. lol!

    what are those little y shaped things one the cells? I thought HIV was wrapped in a membrane that fused with the membrane of a host cell. I do have a poor understanding of viruses though.

    Cool discover!

    The "Y" shaped thing on cells is a receptor. HIV has surface glycoproteins (gp160 complex made of gp40 and gp120) which are those stick and ball on the virus. "Almost" everything attaches through a "lock & key" mechanism. It is still unknown which kind of receptors HIV uses to bind to epithelial cells, but HIV's target cells are CD4+ T cells which are the round cells at the very bottom. For that, the "Y" represents a CD4 receptor which is the primary receptor (along with a co-receptor in form of CCR4/5) that mediates HIV entry into T cells.
