The metabolic environment within solid tumors drives a complex crosstalk between macrophages and NK cells.
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 2 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 tumor microenvironment (TME) exerts significant metabolic limitations that influence the activity of invading immune cells. Among them, macrophages and natural killer (NK) cells are essential for coordinating anti-tumor immunity; however, the metabolic conditions of solid tumors have a significant impact on their functional states. Emerging evidence indicates that metabolic competition and nutrition availability regulate the dynamic interactions between these two innate immune populations, eventually influencing immune activation, suppression, and tumor growth. In this review, we discuss how key metabolic factors, including glucose depletion, lipid metabolism, hypoxia, and lactate accumulation, reshape NK cell activity and macrophage polarization in the TME. We emphasize how cytokine signaling and spatial organization within tumors influence NK-macrophage interactions, resulting in either synergistic anti-tumor responses or immunosuppressive networks. Finally, we explore novel therapeutic approaches designed to target metabolic pathways to restore NK cell function and reprogram macrophages toward pro-inflammatory phenotypes. Understanding the metabolic regulation of NK-macrophage interactions could provide new opportunities to improve immunotherapy efficacy in solid tumors.
