siRNA against KIR3DL1 as a potential gene therapeutic agent in controlling HIV-1 infection.
Article in Viral immunology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThe aim of this study was to develop a small interfering RNA (siRNA) against the expression of KIR3DL1 receptor on natural killer (NK) cells, in order to promote the ability of NK cells to destroy human immunodeficiency virus (HIV)-infected cells and thus prevent failure of siRNA therapy targeting human immunodeficiency virus type 1 (HIV-1) virus among HIV-1 infected patients in vitro.
methodsA siRNA targeting KIR3DL1 was synthesized and then modified with cholesterol, methylene, and sulfate. The inhibitory action of the siRNAs on primary cultured NK cells was detected. The amount of IFN-γ and TNF-α secretions in NK cells was measured. The intended functions of NK cells in vitro were analyzed by CFSE and PI methods.
resultsThere were no significant differences in inhibiting the expression of KIR3DL1 on NK cells between the modified and unmodified siRNAs, while inhibition by each of them differed significantly from controls. The amount of IFN-γ and TNF-α secretions in the NK cells was abundant due to unsuccessful expression of KIR3DL1 on NK cells, which further promoted function of the NK cells.
conclusionThe siRNA against KIR3DL1 could enhance the ability of the NK cells to kill the HIV-1 infected cells in vitro and successfully prevented the failure of siRNA therapy targeting the HIV-1 virus. Therefore, it can act as a potential gene therapeutic agent among HIV-1 infected people.
