Article Title: SARS-CoV-2 Modulation of HIV Latency Reversal in a Myeloid Cell Line: Direct and Bystander Effects

doi: 10.3390/v16081310

Figure Lengend Snippet: ( A ) Relative ACE2 expression levels in different U1 and U937 cells ( left ) and representative histograms of median fluorescence intensity (MFI) for each condition ( right ). Among U1, different conditions were evaluated, such as US: unstimulated U1; cfv: U1 exposed to SARS-CoV-2 cell-free; U937: unstimulated U937. U1 exposed to conditioned media (CM) obtained from non-infected MDM (Ni), MDM exposed to SARS-CoV-2 (Wh), MDM polarized (M1, or M2). PMA (Phorbol 12-myristate 13-acetate): positive control for reversal on both HIV-latently infected cell models. Data show the mean ± SEM, and statistical significance was calculated by one-way ANOVA. ( B ) Kinetics of the SARS-CoV-2 (Wh variant, MOI: 0.1) replication in myeloid (U1, U937) cells measured using RT-qPCR targeted to N and ORF1a genes in culture supernatant, as described in M&M. T0: supernatant obtained after three cell washes. 72 h: 3 days post-infection. Data are expressed as mean ± SD obtained from 4 independent experiments. (* p < 0.05; *** p < 0.001).

Figure Lengend Snippet: Figure 2. DHA differentially modulates ACE1 and ACE2 levels in growing and quiescent EA.hy926 en- dothelial cells. Western blotting was used to compare ACE1 and ACE2 relative to total protein load, as measured by Ponceau S in growing cells treated with ALA, EPA, or DHA at the indicated concentrations (µM) for (a) 8 and (b) 24 h, as well as in quiescent cells treated with n3-PUFA for (c) 8 and (d) 24 h. The band intensities of ACE2 and ACE1 were quantified and are graphically presented in panels (e,f), respectively; the 100 kDa band (grey bars) represents non-glycosylated ACE2, whereas the 130 kDa band (black bars) corresponds to N-glycosylated ACE2. Data are presented as mean ± SEM, n = 3; bars not sharing a common letter in the graphs are significantly different (p < 0.05) based on Duncan’s multiple range or LSD post-hoc tests.

Figure Lengend Snippet: Figure 5. Schematic of proposed mechanism of action. LCn3-PUFAs, EPA and DHA, reduce ACE2 protein levels. These n3-PUFAs may also decrease ACE2 glycosylation. These mechanisms may explain how DHA blocks SARS-CoV-2 pseudovirus entry into HEK293 cells. LCn3-PUFAs also downregulate ACE1 protein levels, thus maintaining the balance between ACE1 and ACE2, and diminishing the risk of adverse CVD outcomes. This figure was prepared by S. Huang using Microsoft PowerPoint software version 16.16.27.
