Lack of TNF-alpha promotes caspase-3-independent apoptosis during murine cytomegalovirus retinitis.

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
purposeBoth caspase-dependent and caspase-independent apoptosis contribute to retinal damage during murine cytomegalovirus (MCMV) retinitis, and TNF-α is among the inducers of apoptosis. The aim of this study was to determine the contribution of TNF-α by studying virus replication and apoptosis in immunosuppressed (IS) TNF-α(-/-) mice.
methodsIS TNF-α(-/-) mice or wild-type mice were inoculated with MCMV by the supraciliary route. Injected eyes were examined by plaque assay, electron microscopy, Western blot analysis (caspase-3, caspase-8, caspase-12, Bid, NF-κB, cFlip, XIAP), staining for MCMV early antigen, and TUNEL assay.
resultsAlthough the titer of MCMV was similar in both groups, significantly more apoptotic cells were observed in the retinas of IS TNF-α(-/-) mice than in those of wild-type mice. The level of active caspase-3 was similar in both groups; however, more activated proteins for genes involved in the mitochondrial pathway (cleaved caspase-8, tBid) and endoplasmic reticulum (ER) stress (cleaved caspase-12) and, though less active, NF-κB subunits and antiapoptotic proteins (XIAP and cFlip) were detected in the TNF-α(-/-) eyes compared with wild-type mice.
conclusionsAlthough TNF-α is an inducer of apoptosis, the results of this study suggest that TNF-α is also antiapoptotic by the following mechanism: TNF-α activation of NF-κB promotes the production of the antiapoptosis genes, c-flip or XIAP, which, in turn, inhibit the activation of caspase-8 and the mitochondrial pathway or the activation of caspase-12 and ER stress.
