Two Additional Connections between the Transcriptional Programs Controlling Invasion and Intracellular Replication of Salmonella: HilD-SprB Positively Regulates

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
Salmonella virulence relies on the ability of this bacterium to invade the intestinal epithelium and to replicate inside macrophages, which are functions mainly encoded in Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2), respectively. Complex regulatory programs control the expression of SPI-1 and SPI-2 and functionally related genes, involving the integration of ancestral regulators and regulators that Salmonella has acquired during its evolution. Interestingly, some previous studies have revealed cross talk between the regulatory programs for SPI-1 and SPI-2. Here, we report two additional connections between the regulatory programs controlling the expression of genes for invasion and intracellular replication. Our results show that the acquired regulators HilD and SprB, both encoded in SPI-1, induce, in a cascade fashion, the expression of PhoP and SlyA, two ancestral regulators that activate the expression of SPI-2 and other genes required for intracellular replication. We provide evidence supporting that the regulation of
