TLR2 and TLR4 mediate the TNFα response to Vibrio vulnificus biotype 1.

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
Vibrio vulnificus (Vv) is a pathogenic bacterium that can cause life-threatening infections in humans. Most fatal cases are due to septic shock that results from dysregulation of cytokines, particularly TNFα, which plays a critical role in the outcome of Vv infection. The goal of this study was to investigate the Toll-like receptor (TLR)-mediated TNFα response to four Vv biotype 1 strains using mice deficient for TLR2, TLR4, and TLR2/TLR4. Ex vivo assays were performed with blood, splenocytes, and Kupffer cells (KC) from wild-type (WT) and TLR-knockout (KO) mice using formalin-inactivated Vv (f-Vv) as stimulant. All f-Vv biotype 1 strains elicited strong TNFα production by WT mouse blood and cells, which was TLR2 and TLR4 dependent. OxPAPC, an inhibitor of TLR2 and TLR4 signaling, effectively blunted the TLR-mediated TNFα response to f-Vv. Furthermore, TLR2 KO and TLR2/TLR4 KO mice were more resistant to lethal infection with Vv ATCC 27562 than WT mice, perhaps due to attenuation of the TNFα response. These data suggest that it may be possible to devise strategies to specifically target the harmful TLR-mediated TNFα response as an adjunct to antibiotic treatment of severe Vv infection.
