1 · What the graph read from it

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.

2 · The registry

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

Several studies have reported a crucial role for cholesterol-enriched membrane lipid rafts and cell-associated heparan sulfate proteoglycans (HSPGs), a class of molecules that can localize in lipid rafts, in the entry of human immunodeficiency virus type 1 (HIV-1) into permissive cells. For the present study, we examined the role of these cell surface moieties in HIV-1 entry into primary human brain microvascular endothelial cells (BMVECs), which represent an important HIV-1 central nervous system-based cell reservoir and a portal for neuroinvasion. Cellular cholesterol was depleted by exposure to beta-cyclodextrins and 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A reductase inhibitors (statins), the loss of cholesterol was quantitated, and disruption of membrane rafts was verified by immunofluorescence. Nevertheless, these treatments did not affect binding of several strains of HIV-1 virions to BMVECs at 4 degrees C or their infectivities at 37 degrees C. In contrast, we confirmed that cholesterol depletion and raft disruption strongly inhibited HIV-1 binding and infection of Jurkat T cells. Enzymatic digestion of cell-associated HSPGs on human BMVECs dramatically inhibited HIV-1 infection, and our data from quantitative HIV-1 DNA PCR analysis strongly suggest that cell-associated chondroitin sulfate proteoglycans greatly facilitate infective entry of HIV-1 into human BMVECs. These findings, in combination with our earlier work showing that human BMVECs lack CD4, indicate that the molecular mechanisms for HIV-1 entry into BMVECs are fundamentally different from that of viral entry into T cells, in which lipid rafts, CD4, and probably HSPGs play important roles.
