The tumor suppressor p15Ink4b regulates the differentiation and maturation of conventional dendritic cells.

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
The tumor suppressor p15Ink4b is frequently inactivated by methylation in acute myeloid leukemia and premalignant myeloid disorders. Dendritic cells (DCs) as potent APCs play critical regulatory roles in antileukemic immune responses. In the present study, we investigated whether p15Ink4b can function as modulator of DC development. The expression of p15Ink4b is induced strongly during differentiation and activation of DCs, and its loss resulted in significant quantitative and qualitative impairments of conventional DC (cDC) development. Accordingly, ex vivo-generated BM-derived DCs from p15Ink4b-knockout mice express significantly decreased levels of the antigen-presenting (MHC II) and costimulatory (CD80 and CD86) molecules and have impaired immunostimulatory functions, such as antigen uptake and T-cell stimulation. Reexpression of p15Ink4b in progenitors restored these defects, and confirmed a positive role for p15Ink4b during cDC differentiation and maturation. Furthermore, we have shown herein that p15Ink4b expression increases phosphorylation of Erk1/Erk2 kinases, which leads to an elevated activity of the PU.1 transcription factor. In conclusion, our results establish p15Ink4b as an important modulator of cDC development and implicate a novel function for this tumor suppressor in the regulation of adaptive immune responses.
