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

CD4(+)CD25(+)FoxP3(+) regulatory T cells (Tregs) are critical for immune homeostasis and tolerance. However, because of their capacity to suppress antigen presenting cells (APC), T and B cells, Tregs could also inhibit protective immune responses to viruses and vaccines. Several viruses have been shown to exploit Tregs to evade immune response. By modulating APC and in particular by weakening the functions of dendritic cells such as their ability to secrete polarizing cytokines and expression of co-stimulatory molecules, viruses could support differentiation and expansion of Tregs. Of note, as a proof of concept, depletion of Tregs significantly enhanced the protective immune response to viruses and vaccines suggesting that Tregs are viable targets to enhance immunogenicity of vaccines. As Treg depletion or inhibition of their functions could lead to deleterious autoimmune and inflammatory disorders, any Treg-based approach for vaccination should not aim at depletion of Tregs and inhibition of their functions should be transient. Recent studies have targeted the interaction between CCR4 expressed on Tregs and its ligands CCL22 and CCL17 to inhibit transiently the recruitment of Tregs at the site of immunization. Importantly, use of CCR4 antagonists as 'molecular adjuvants' in vivo in experimental models, amplified cellular and humoral immune responses when injected in combination with various vaccine antigens. The significant adjuvant activity observed in diverse models without noticeable side effects provided strong evidence that CCR4 is a sustainable target for rational adjuvant design.
