Increased expression of SAMHD1 in a subset of HIV-1 elite controllers.

Results: We show that a subset of HIV+ elite controllers with lower T cell proliferation levels (Ki67+ cells) expressed higher SAMHD1 compared with healthy donors or viraemic progressors. Conversely, there was no difference in p21 expression before or after T cell activation with a bispecific CD3/CD8 antibody.
