In this image of lymph tissue taken from the neck of a person with uncontrolled HIV infection, you can see areas where HIV is replicating (in red) amidst a sea of immune cells (blue dots ). Areas of greatest HIV replication are associated with a high density of a subtype of human CD4 T cells (yellow circles) that have been shown to be particularly susceptible to HIV infection.
