IFITM2 Modulates Endocytosis Maintaining Neural Stem Cells in Developing Neocortex.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. 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
Brain development is orchestrated by a complex interplay of genetic and environmental signals, with endocytosis serving as a pivotal process in integrating extracellular cues. However, the specific role of endocytosis in neurogenesis remains unclear. We uncover a critical function of the interferon-induced transmembrane protein, IFITM2, essential for endocytic processes in radial glial cells (RGCs). IFITM2 is highly expressed near the ventricular surface in the developing brain. Loss of IFITM2 impairs endosome formation and disrupts RGC maintenance. Mechanistically, we confirmed that the YXXø endocytic motif on IFITM2 is essential for its subcellular localization, with mutations in this motif reducing endocytic vesicles. Additionally, the K82 and K87 residues of IFITM2 interact with phosphoinositides to promote endocytic vesicle formation. Polarized localization of phosphatidylinositol 3,4-bisphosphate (PI(3,4)P2) on the ventricular side suggests its role in vesicle formation. IFITM2 deficiency also leads to reduced phosphorylation of AKT and GSK3β. These findings highlight the essential role of IFITM2 in regulating endocytosis in RGCs, which is critical for maintaining neural stem cells and proper brain development, offering new insights into the connection between cellular signaling and neurogenesis in both mouse and human models.
