Dendritic cell-mediated HIV-1 infection of T cells demonstrates a direct relationship to plasma viral RNA levels.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo examine the relationship between infectivity of HIV-1 variants in dendritic cell (DC)-mediated in trans infection of T cells and plasma viral RNA levels in infected subjects.
methodsHIV-1 was isolated from peripheral blood mononuclear cells of chronically infected individuals, typed for coreceptor usage, and viral replication were examined in monocyte-derived DCs-peripheral blood lymphocytes cocultures. The rate of p24 antigen production during the logarithmic phase of viral replication was determined by enzyme-linked immunosorbent assay. Additionally, nef variants were cloned and expressed in trans with a HIV luciferase vector and CCR5-tropic HIV-1 envelope, and infectivity was measured in DC-mediated capture-transfer assays.
resultsReplication capacity of HIV-1 viral CCR5-tropic isolates in monocyte-derived dendritic cells-peripheral blood lymphocytes cocultures was linearly associated with the plasma viral RNA levels in a cohort of HIV-1-infected individuals exhibiting an inverse relationship between plasma viral RNA and CD4 cell count. Furthermore, infectivity activity of nef variants in context of DC-mediated enhanced infection of T cells also showed a linear relationship to plasma viral RNA levels.
conclusionsThese results illustrate that replication capacity of HIV-1 in DC T-cell cultures is a significant determinant of plasma viral RNA level. The data suggest that adaptation of HIV-1 to DC interactions with T cells influences the level of viral replication in the host.
