Interleukin-4 Aggravates LPS-Induced Striatal Neurodegeneration In Vivo via Oxidative Stress and Polarization of Microglia/Macrophages.
Article in International journal of molecular sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
The present study investigated the effects of interleukin (IL)-4 on striatal neurons in lipopolysaccharide (LPS)-injected rat striatum in vivo. Either LPS or PBS as a control was unilaterally injected into the striatum, and brain tissues were processed for immunohistochemical and Nissl staining or for hydroethidine histochemistry at the indicated time points after LPS injection. Analysis by NeuN and Nissl immunohistochemical staining showed a significant loss of striatal neurons at 1, 3, and 7 days post LPS. In parallel, IL-4 immunoreactivity was upregulated as early as 1 day, reached a peak at 3 days, and was sustained up to 7 days post LPS. Increased levels of IL-4 immunoreactivity were exclusively detected in microglia/macrophages, but not in neurons nor astrocytes. The neutralizing antibody (NA) for IL-4 significantly protects striatal neurons against LPS-induced neurotoxicity in vivo. Accompanying neuroprotection, IL-4NA inhibited activation of microglia/macrophages, production of reactive oxygen species (ROS), ROS-derived oxidative damage and nitrosative stress, and produced polarization of microglia/macrophages shifted from M1 to M2. These results suggest that endogenous IL-4 expressed in LPS-activated microglia/macrophages contributes to striatal neurodegeneration in which oxidative/nitrosative stress and M1/M2 polarization are implicated.
