Trichomide A, a natural cyclodepsipeptide, exerts immunosuppressive activity against activated T lymphocytes by upregulating SHP2 activation to overcome contact dermatitis.

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
Increasing numbers of people are suffering from allergic contact dermatitis. However, the immunosuppressive drug candidate with negligible toxicity is still deficient. In the present study, we identified a natural cyclodepsipeptide named trichomide A that effectively inhibited the proliferation of activated T cells and reduced the production of proinflammatory cytokines but had almost no toxic effect on naive T cells at 0.3-3 μM. In addition, trichomide A caused G0/G1 phase arrest, suppressed the activation of AKT and STAT3, and increased the level of phosphorylated SHP2 in activated T cells in dose- and time-dependent manners. Furthermore, an in vivo experiment demonstrated that trichomide A significantly ameliorated picryl chloride (PCI)-induced contact hypersensitivity in mice. Such effects of trichomide A in the aforementioned experiments were significantly reversed by the inhibition of SHP2 activity using the SHP2-specific inhibitor PHPS1 or conditional SHP2 knockout mice in T cells, suggesting the SHP2-dependent action of trichomide A. Taken together, trichomide A showed an immunosuppressive activity against T cell-mediated immune responses both in vitro and in vivo, which has potential for the treatment of immune-related skin diseases.
