1 · What the graph read from 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.

2 · The registry

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

The human gut must regulate its immune response to resident and pathogenic bacteria, numbering in the trillions. The peptidoglycan component of the bacterial cell wall is a dense and rigid structure that consists of polymeric carbohydrates and highly cross-linked peptides which offers protection from the host and surrounding environment. Nucleotide-binding oligomerization domain-containing protein 2 (NOD2), a human membrane-associated innate immune receptor found in the gut epithelium and mutated in an estimated 30% of Crohn's disease patients, binds to peptidoglycan fragments and initiates an immune response. Using a combination of chemical synthesis, advanced analytical assays, and protein biochemistry, we tested the binding of a variety of synthetic peptidoglycan fragments to wild-type (WT)-NOD2. Only when the protein was presented in the native membrane did binding measurements correlate with a NOD2-dependent nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) response, supporting the hypothesis that the native-membrane environment confers ligand specificity to the NOD2 receptor for NF-κB signaling. While N-acetyl-muramyl dipeptide (MDP) has been thought to be the minimal peptidoglycan fragment necessary to activate a NOD2-dependent immune response, we found that fragments with and without the dipeptide moiety are capable of binding and activating a NOD2-dependent NF-κB response, suggesting that the carbohydrate moiety of the peptidoglycan fragments is the minimal functional epitope. This work highlights the necessity of studying NOD2-ligand binding in systems that resemble the receptor's natural environment, as the cellular membrane and/or NOD2 interacting partners appear to play a crucial role in ligand binding and in triggering an innate immune response.
