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 membrane-bound CD4 glycoprotein has been proposed to act like a co-receptor along with the T-cell antigen receptor (TCR/CD3) during ligand recognition and cell activation. Due to its association with the protein tyrosine kinase (PTK) p56lck, CD4 is believed to transduce a signal and support CD3 activation of T cells. In this study we have shown that CD3 ligation on murine T-cell hybridomas induces tyrosine phosphorylation of proteins, including phospholipase C-gamma 1 (PLC gamma 1), both in the presence as well as in the absence of CD4-linked p56lck. Furthermore, using HPB clones deficient in CD3/PTK association, it has been found that the presence of CD4/p56lck does not overcome the defect in signalling. Not even co-aggregation of CD4 with CD3 triggers tyrosine phosphorylation of proteins in these cells. Together, the present results indicate that CD3-linked PTK(s) plays a primary role in the induction of signalling through TCR/CD3, and the presence of CD4/p56lck is neither necessary nor sufficient to elicit these events. In the light of these results a possible role for CD4 in antigen presentation has been proposed.
