ROS-Mediated Necroptosis Promotes Coxsackievirus B3 Replication and Myocardial Injury.
Article in Microorganisms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Coxsackievirus B3 (CVB3) is a primary causative agent of viral myocarditis (VMC), which can lead to both acute and chronic cardiac inflammation accompanied by progressive heart failure and arrhythmias. Although CVB3 has been implicated in various forms of programmed cell death, whether it triggers necroptosis and the underlying mechanisms remains unclear. This study aimed to investigate the role and mechanism of CVB3-induced necroptosis and its effect on viral replication. Using both in vitro and in vivo models, we demonstrated that CVB3 infection significantly upregulates the expression of key necroptotic markers RIP1 and RIP3 in HeLa cells and mouse myocardial tissues. This upregulation was accompanied by elevated intracellular reactive oxygen species (ROS) levels and suppression of the Nrf2/HO-1 antioxidant pathway. Intervention with the necroptosis inhibitor Necrostatin-1 (Nec-1) or the ROS scavenger N-acetylcysteine (NAC) markedly attenuated cell death, suppressed viral replication, and ameliorated myocardial injury and inflammatory responses in infected mice. Mechanistically, CVB3 inhibits the Nrf2/HO-1 pathway, thereby inducing substantial ROS accumulation that promotes necroptosis. This effect can be reversed by NAC treatment. Our study reveals a novel mechanism through which CVB3 induces ROS-dependent necroptosis via the suppression of the Nrf2/HO-1 pathway, providing new insights into the pathogenesis of viral myocarditis and suggesting potential therapeutic strategies.
