Tropism Tests

..."Naturally" Block the CCR5 Receptor How Is the Test Used? How Is Viral Tropism Measured? How Reliable Is the Test? What Do the Results Mean? Are There Problems With the Tropism Test? What Is Viral Tropism? When HIV attaches to a CD4 cell it is going to infect, it uses molecules on the cell surface. These are called receptors or chemokine co-receptors. The first receptor HIV uses is the CD4 molecule. The virus then uses a...
