Here, we show across a diverse cohort of posttreatment controllers (PTCs), posttreatment noncontrollers (NCs), and spontaneous elite controllers (ECs) that robust expansion of HIV-specific CD8\n                    <jats:sup>+<\/jats:sup>\n                    T cells and reduced viral reservoir diversity were strongly associated with durable (&gt;1 year) viral suppression after ART cessation.

Mapping of CD8\n                    <jats:sup>+<\/jats:sup>\n                    T cell responses from PTCs revealed broad targeting of epitopes in a conserved autologous reservoir, whereas preferential targeting of epitopes derived from mutationally constrained regions was primarily a feature of CD8\n                    <jats:sup>+<\/jats:sup>\n                    T cells from ECs.
