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

backgroundThe scavenger receptor cysteine rich (SRCR) domain is an ancient and conserved protein domain. CD163 and WC1 molecules are classed together as group B SRCR superfamily members, along with Spalpha, CD5 and CD6, all of which are expressed by immune system cells. There are three known types of CD163 molecules in mammals, CD163A (M130, coded for by CD163), CD163b (M160, coded for by CD163L1) and CD163c-alpha (CD163L1 or SCART), while their nearest relative, WC1, is encoded by a multigene family so far identified in the artiodactyl species of cattle, sheep, and pigs.

resultsWe annotated the bovine genome and identified genes coding for bovine CD163A and CD163c-alpha but found no evidence for CD163b. Bovine CD163A is widely expressed in immune cells, whereas CD163c-alpha transcripts are enriched in the WC1+ gammadelta T cell population. Phylogenetic analyses of the CD163 family genes and WC1 showed that CD163c-alpha is most closely related to WC1 and that chicken and platypus have WC1 orthologous genes, previously classified as among their CD163 genes.

conclusionSince it has been shown that WC1 plays an important role in the regulation of gammadelta T cell responses in cattle, which, like chickens, have a high percentage of gammadelta T cells in their peripheral blood, CD163c-alpha may play a similar role, especially in species lacking WC1 genes. Our results suggest that gene duplications resulted in the expansion of CD163c-alpha-like and WC1-like molecules. This expanded repertoire was retained by species known as "gammadelta T cell high", but homologous SRCR molecules were maintained by all mammals.
