FIG. 4.
Representative CD4 and CD8 expression on thymocytes from thymus/liver grafts 3, 6, and 12 weeks after infection with HIV-1 ACH142-8G9, ACH142-32D2, or ACH142-*E11. Thymus/liver grafts were biopsied, a single-cell suspension was made, and the cells were stained with fluorochrome-conjugated CD4 and CD8 MAbs. Expression of the corresponding cell surface antigens was measured by flow cytometry. The data are representative of those summarized in Table 3.
