Role of early- or late-phase activation of p38 mitogen-activated protein kinase induced by tumour necrosis factor-alpha or 2,4-dinitrochlorobenzene during maturation of murine dendritic cells.
Article in Immunology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Dendritic cells (DCs) are maturated by a variety of stimuli. However, the precise mechanisms underlying the maturation of DCs are not fully understood. In the present study, we analysed the effects of tumour necrosis factor-alpha (TNF-alpha) and 2,4-dinitrochlorobenzene (DNCB) on phenotypic maturation and p38 mitogen activated protein kinase (MAPK) activity, using a murine DC line. TNF-alpha markedly increased the surface expression of major histocompatibility complex (MHC) and costimulatory molecules, CD86 and CD80, on DCs. DNCB more markedly enhanced the surface expression of costimulatory molecules, but showed less stimulatory capability on MHC molecules, compared with TNF-alpha. Simultaneous treatment of DCs with TNF-alpha and DNCB showed additive enhancement of costimulatory molecule expression. TNF-alpha activated p38 MAPK in DCs only at an early time-point (15 min). In contrast, DNCB activated p38 MAPK at later time-points (3-6 hr). SB203580, a specific inhibitor of p38 MAPK, partially or markedly inhibited the phenotypic changes of DCs induced by TNF-alpha or DNCB, respectively. In addition, N-acetyl-l-cysteine, a reducing supplier, completely inhibited the DNCB-induced expression of MHC and costimulatory molecules, but not those induced by TNF-alpha. These findings demonstrate that TNF-alpha and DNCB activate the p38 MAPK pathway at an early and a late phase, respectively, and thereby induce DC maturation through different signal pathways.
