In situ hybridization to detect and localize signature cytokines of T-helper (Th) 1 and Th2 immune responses in chicken tissues.

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 avian immune system has been shown to possess a repertoire of cytokines directing T-helper (Th) 1 and Th2 types of immune responses similar to that in mammals. The objective of this study was to establish in situ hybridization (ISH) for the localization of mRNA of selected signal cytokines, chicken interferon-γ (ChIFN-γ), chicken interleukin (ChIL)-4 and ChIL-13 in fixed tissues. RNA probes were generated to hybridize to 488, 318, and 417bp of the respective target mRNA. Probe concentrations ranging from 100ng/ml to 400ng/ml were shown to be suitable to label cells that expressed these cytokines. The specificity of every probe was verified using the respective sense probe. ChIFN-γ, ChIL-4 and ChIL-13 positive cells were observed in the lymphocytic infiltrations of liver and in the periarteriolar lymphatic sheaths of spleen collected from specific-pathogen-free chickens. ISH of these cytokines in a severely inflamed liver due to infiltration with the parasite Histomonas meleagridis revealed the expression of both ChIFN-γ and ChIL-13 mRNA in the mononuclear infiltrates. In conclusion, ChIFN-γ, ChIL-4 and ChIL-13 mRNA were efficiently localized by ISH, which supplies a valid technique to characterize immune responses in fixed tissues.
