The Arp2/3 complex controls the development of homeostatic microglia.
Article in EMBO reports, 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
Microglial dynamics and homeostasis are crucial for maintaining central nervous system (CNS) function. To fulfill their homeostatic functions, microglia develop into ramified cells with highly dynamic cell protrusions. However, the detailed mechanisms underlying this developmental transition are largely unknown. Here, we investigate the role of the Actin-related protein 2/3 (Arp2/3) complex, a critical actin nucleator that controls the formation of actin branches, for the biology of tissue-resident microglia. By conditionally targeting Arpc4 in mice, we show that Arp2/3 depletion in tissue-resident microglia causes phenotypes beyond previously reported functions in other immune cell types. Our results identify an important role of Arp2/3 for controlling the developmental transition of microglia into cells with ramified morphology, homeostatic gene profile, and surveillance function in the CNS. Together, our results link actin remodeling to microglial maturation and activation, highlighting the Arp2/3 complex as a critical factor for maintaining the plasticity and preventing pathological activation of endogenous microglia.
