Evidence for microvesicle particles in UVB-mediated IL-8 generation in keratinocytes.

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
Recent studies have implicated bioactive microvesicle particles (MVP) in the keratinocyte response to many environmental stressors, in partricular ultraviolet B radiation (UVB). The generation of MVP in response to UVB involves the Platelet-activating factor receptor (PAFR) and the enzyme acid sphingomyelinase (aSMase). As UVB generates some cytokines such as interleukin-8 (IL-8) in a PAFR-dependent manner, one question is if the production and release of IL-8 and MVP could be linked. Using the human keratinocyte-derived cell line HaCaT, the present in vitro studies indicate that pretreatment of HaCaT keratinocytes with PAFR agonist ester can synergize with low fluences of UVB to generate high levels of MVP as well as IL-8 protein. Treatment of cells with an aSMase pharmacologic inhibitor blocked both processes. These studies indicate the possibility that MVP could be involved in pathologic processes involving UVB-generated production of pro-inflammatory cytokines such as IL-8.
