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

HLA-F has low levels of polymorphism in humans and is highly conserved among primates, suggesting a conserved function in the immune response. In this study, we probed the structure of HLA-F on the surface of B lymphoblastoid cell lines and activated lymphocytes by direct measurement of peptide binding to native HLA-F. Our findings suggested that HLA-F is expressed independently of bound peptide, at least in regard to peptide complexity profiles similar to those of either HLA-E or classical MHC class I (MHC-I). As a further probe of native HLA-F structure, we used a number of complementary approaches to explore the interactions of HLA-F with other molecules, at the cell surface, intracellularly, and in direct physical biochemical measurements. This analysis demonstrated that HLA-F surface expression was coincident with MHC-I H chain (HC) expression and was downregulated upon perturbation of MHC-I HC structure. It was further possible to directly demonstrate that MHC-I would interact with HLA-F only when in the form of an open conformer free of peptide and not as a trimeric complex. This interaction was directly observed by coimmunoprecipitation and by surface plasmon resonance and indirectly on the surface of cells through coincident tetramer and MHC-I HC colocalization. These data suggest that HLA-F is expressed independently of peptide and that a physical interaction specific to MHC-I HC plays a role in the function of MHC-I HC expression in activated lymphocytes.
