We tested the capacity of CXCL12 to inhibit infection of CD4TL with viruses pseudotyped with Envs of virus clones isolated from PBMCs of 5 patients (P) of the Amsterdam cohort (ACS) (Figs 1A and S1A and S1B), three treatment naïve, two under AZT monotherapy (S1 Table). Here, CXCL12 is linked to infection.
