Expression of Th1/Th2 cytokine mRNA in peritoneal exudative polymorphonuclear neutrophils and their effects on mononuclear cell Th1/Th2 cytokine production in MRL-lpr/lpr mice.

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
Peritoneal exudative polymorphonuclear neutrophils (PEC-PMN) and mononuclear cells (PEC-MNC) were obtained from normal BALB/c and from autoimmune MRL-lpr/lpr mice (lpr) with different disease severities. The spontaneous and mitogen-stimulated expression of T-helper lymphocyte type-1 (Th1) [represented by interferon-gamma (IFN-gamma) and interleukin (IL-2)] and T-helper lymphocyte type-2 (Th2) (represented by IL-4 and IL-10) cytokine mRNA in these cells was detected by reverse transcription-polymerase chain reaction (RT-PCR). The production of these cytokines was measured by enzyme-linked immunosorbent assay (ELISA). We found that the spontaneous expression of Th1/Th2 cytokine mRNA in PEC-PMN from autoimmune mice was progressively increased in parallel with disease severity but was not changed by lipopolysaccharide (LPS) stimulation. By contrast, spontaneous expression of Th1/Th2 cytokine mRNA in PEC-MNC from these mice was progressively decreased in parallel with disease severity but retained the responsiveness to phytohaemagglutinin (PHA) stimulation. To determine the effect of PEC-PMN on Th1/Th2 cytokine production by PEC-MNC, autologous PEC-PMN and PEC-MNC were co-cultured at MNC:PMN ratios of 5:0, 4:1, 3:2, 2:3, 1:4 and 0:5 with PHA stimulation for 24 hr. The production of cytokines at each ratio was compared with the expected value, by calculation. We found that PEC-PMN from autoimmune mice progressively suppressed the production of IL-4, IL-10 and IFN-gamma whereas the production of IL-2 was enhanced by autologous MNC in parallel with disease severity. These results suggest that a reciprocal relationship exists in the expression of Th1/Th2 cytokine mRNA between PEC-PMN and PEC-MNC in lpr mice in parallel with disease severity. Autoimmune PEC-PMN can exert significant modulatory effects on Th1/Th2 cytokine production by autologous MNC in stimulation.
