The GI tract memory CD4⁺ T lymphocyte population is a major viral reservoir in SIV-infected AGMs. The numbers of SIVsab DNA copies per 10⁶ cells in the DN, CD4⁺ CD95⁻, CD4⁺ CD95⁺, and CD8⁺ CD95⁺ T lymphocyte populations are shown in panel A for peripheral blood, panel B for ileum, panel C for mesenteric lymph nodes, panel G for axillary lymph nodes, panel H for spleen, and panel I for bone marrow. The frequencies of DN, CD4⁺ CD95⁻, CD4⁺ CD95⁺, and CD8⁺ CD95⁺ T lymphocytes in the total CD3⁺ T lymphocyte population in each anatomic compartment are shown in panels D to F and J to L. Horizontal lines represent medians.
