No evidence for paradoxical effects of tocilizumab in rodents.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Interleukin-6 (IL-6) is a multifunctional cytokine with important functions in health and disease. In order to activate its target cells, IL-6 binds first to the IL-6 receptor (IL-6R), which in turn induces the recruitment and homodimerization of the signal-transducing β-receptor gp130 and the activation of intracellular signaling cascades, including the phosphoinositide 3-kinase (PI3K)-AKT cascade. IL-6 is involved in the pathogenesis of multiple inflammatory diseases, and tocilizumab, a monoclonal antibody that binds to the IL-6R and thus blocks the biological activities of IL-6, is in clinical use worldwide for the treatment of patients with inflammatory diseases, including rheumatoid arthritis. Recently, Weng and colleagues published a paper in Naunyn-Schmiedeberg's Archives of Pharmacology describing paradoxical effects of tocilizumab when used on murine cells in vitro and in a rat model of acute lung injury in vivo. In this communication, I provide evidence that the results presented by Weng and colleagues are not compatible with what is known about the biology of IL-6 and highlight why the provided evidence is insufficient to believe that tocilizumab shows the reported paradoxical effects in rodents.
