“…Our results confirm and extend the results of Shan and colleagues ( Shan et al., 2017 ) showing that activated-to-memory transitioning CD4 + T cells are more prone to latent HIV-1 infection. Using a dual-reporter virus that distinguishes between productively and latently infected cells ( Battivelli et al., 2018 ; Lopez et al., 2022 ; Ratnapriya et al., 2021 ), we show that the frequency of latent cells increases in activated-to-memory transitioning CD4 + T cells, which, indeed, display a transient increase in CCR5 expression. The mechanism involved in the gradual increase in CCR5 expression following the activation of the TCR with anti-CD3/CD28 antibodies appears partially linked to a decrease in the levels of p53 mRNA.…”

“…T cells were labeled at days 6–8 using CMAC (10 µM) cell tracker dye (Invitrogen), and glass slide chambers were constructed as previously described ( Lopez et al, 2019 ; Lopez et al, 2022 ). Briefly, 2 × 10 6 cells were mixed in 270 µl of bovine collagen (Advanced Biomatrix, Cat# 5005-100ML) at a final concentration of 1.7 mg/ml.…”
