In vivo beta-defensin gene expression in rat gingival epithelium in response to Actinobacillus actinomycetemcomitans infection.
Article in Journal of periodontal research, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
BACKGROUND AND
objectiveHuman beta-defensins have been identified in the oral cavity and are predicted to play a role in the defense against pathogenic bacteria. Homologous rat beta-defensins (RBDs) have been identified, but their expression in the oral cavity has not been examined. Therefore, the aim of this study was to investigate the expression of innate immune mediators in the rat gingival epithelium. MATERIAL AND
methodsRats were pretreated with antibiotics to depress the normal oral flora, followed by the introduction of Actinobacillus actinomycetemcomitans in their food to allow colonization and the development of periodontal disease. At various time points, animals were killed and the gingival epithelium was extracted. Semiquantitative reverse transcription-polymerase chain reaction was performed to measure RBD and Toll-like receptor (TLR) mRNA levels.
resultsThree beta-defensins (RBD-1, -2 and -5) and two TLRs (TLR-3 and -4) are expressed in normal rat gingival epithelium. After the introduction of A. actinomycetemcomitans, RBD-1 and RBD-2 mRNA levels increased for the first week followed by a return to basal levels. No change in TLR mRNA levels was observed.
conclusionThe rat model provides a good system for experimental analysis of the innate immune response to periopathogenic bacteria in the oral cavity, as well as the potential role of beta-defensins in the host response to colonization.
