Depressed production of beta-defensins from mouse splenic dendritic cells following thermal injury and its influence on susceptibility to infection.

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
purposeBeta-defensins (BDs) and dendritic cells (DC) have been described as major effectors on host antimicrobial innate immunities. In the present study, the ability of DC to produce BDs was explored using DC from normal mice and full-thickness (FT)-burned mice.
methodsDCs were isolated from spleens of mice, and 1 × 10(6) cells/ml of them were cultured with LPS or SAC. Culture fluids harvested 24 h after cultivation were assayed for BD1 and BD3 and antibacterial activity (colony-counting, Pseudomonas aeruginosa). Also, DCs were tested for BD mRNAs by RT-PCR.
resultsSixty-five percent of the bacterial killing activity was shown by the culture fluids of splenic DC from normal mice, while only 15 % killing activity was shown by the culture fluids of splenic DC from FT-burned mice. X-irradiated NOD SCID IL-2rγ(null) mice inoculated with splenic DC from FT-burned mice showed increased susceptibility to P. aeruginosa infection compared to those from normal mice. Mice splenic DC expressed BD1 mRNA constitutively and expressed BD3 mRNA after stimulation. These BDs were produced by mice splenic DC. As compared with DC from normal mice, DC from FT-burned mice produced decreased amounts of BD1 and BD3 in their culture fluids.
conclusionsThese results indicate that (1) DC from spleens of mice have an ability to produce BDs, and (2) the production of BDs by DC is influenced strongly by thermally injured stress. Since FT-burned mice are susceptible to P. aeruginosa infection, BDs produced by DC may play an important role on the host's antibacterial resistance.
