And we have the genome, the DNA of that helper T cell inside the nucleus. Now, once this binding process takes place, what happens next is the GP 41 Glycoprotein. The other glycoprotein attached to GP 120 and to the membrane of our virus, initiates or stimulates the cell mediated endocytotic process. This is the process by which the membrane of the virus fuses with the membrane of the cell and that essentially dumps all the viral contents into the cytoplasm of our cell, as shown in this diagram. So we have the fusion of the membrane in tank of the virus and the membrane in blue of that helper T cell. And so this is what happens.
