The HIV virus

The HIV virus is a virus that attacks the bodies CD4 cells, these are the cells the body uses to fight diseases, infections and foreign bodies.  Once infected the virus remains in the body and if not treated will eventually overpower the bodies immune system completely leaving it vulnerable and unable to fight off infections.  The ART drugs in use today are grouped into drug classes each of these are designed to deal with different stages of the HIV virus’s life cycle.

The 7 stages of the HIV life cycle explained

#1 Binding
This is the very first stage of the HIV Lifecycle.  The HIV virus attacks the CD4 cell and attaches Itself to the cell on its surface.  It does this by first attaching to the CD4 cell’s receptor than the CCR5 or the CXCR4 coreceptor.

#2 Fusion
The second stage of the HIV life cycle is called fusion and this is done after the virus has effectively attached itself to the CD4 cell.  The entire HIV viral envelope will then fuse with the cell which allows it to gain entry into it.
