Holding cancer in line: the role of the electron transport chain in tumor-associated macrophages.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Tumor-associated macrophages (TAMs) are a highly heterogeneous population of innate immune cells that is widely enriched in the tumor microenvironment (TME). By suppressing anti-cancer immunity, TAMs sustain tumor growth, metastasis development and contribute to therapy resistance. Due to their remarkable plasticity, TAMs can be reprogrammed towards immune-stimulatory phenotypes, representing a compelling therapeutic option. The mitochondrial electron transport chain (ETC) is central in fueling macrophage metabolism by coupling electron flow with proton transfer to produce Adenosine Triphosphate (ATP). During inflammation, remodeling of the ETC has been shown to regulate macrophage polarization and cytokine production. However, how ETC perturbations influence macrophage phenotypes in other diseases, as during cancer progression and within a nutrient-restricted environment remains largely unexplored. In this mini-review, we examine the role of the ETC and its individual respiratory complexes in governing tumor-associated macrophage behavior, their involvement in tumor immunity, and we discuss the potential to exploit this axis for innovative immunotherapeutic strategies, while also considering current challenges and limitations.
