Control of microglial dynamics by the Arp2/3 complex and the autism- and schizophrenia-associated protein CYFIP1
Open accessAbstract
Microglia use a highly complex and dynamic network of branched processes to sense and respond to their surroundings. Despite emerging evidence that microglial motility plays important roles in brain development, neurodegeneration, and neuropsychiatric disease, little is known about the intracellular machinery orchestrating microglial process dynamics. Here, we identify roles for regulators of the actin cytoskeleton in controlling microglial behavior. We show that the actin branching Arp2/3 complex is critical for maintaining microglial morphology and is required for surveillance but not chemotactic motility. Neuropsychiatric disease-associated CYFIP1, a core component of the WAVE regulatory complex linking upstream signaling pathways to activation of the Arp2/3 complex, is highly expressed in microglia but has an unknown function. We report that conditional deletion of Cyfip1 in mouse microglia reduces their morphological complexity and surveillance of the brain parenchyma, with no effect on chemotaxis. Deletion of Cyfip1 also increased microglial CD68 positive lysosome volume and engulfment of presynapses. Thus, actin remodeling by CYFIP1 and the Arp2/3 complex controls microglial dynamics and shifts microglia away from a homeostatic state with potential implications for neuropsychiatric disease.

TL;DR
The Arp2/3 complex and CYFIP1 are required for maintaining ramified microglial morphology and surveillance motility, while chemotaxis remains intact. Microglial Cyfip1 deletion also increases lysosomal CD68 and presynaptic Bassoon content, suggesting altered phagocytic/lysosomal processing relevant to neuropsychiatric disease.
Key findings
- Arp2/3 inhibition with CK666 reduced the surveillance index from 200.8 ± 28.85 to 79.66 ± 20.96 pixels per 30 s (P = 0.001), a >50% reduction, but did not significantly affect chemotaxis convergence or single-process speed (DMSO: 3.83 ± 0.34 μm/min; CK666: 3.56 ± 0.18 μm/min; P = 0.097).
- CK666-treated microglia had fewer branch points (DMSO: 12.96 ± 2.748; CK666: 6.95 ± 3.25; P = 0.018), more blebbing (DMSO: 10.50 ± 4.61%; CK666: 60.04 ± 6.24%; P < 0.0001), and occupied a smaller area (DMSO: 765.40 ± 80.53 μm²; CK666: 554.40 ± 25.75 μm²; P = 0.009), while total process length was unchanged.
- Microglia-specific Cyfip1 conditional knockout reduced CYFIP1 by approximately 50%, reduced surveillance index by 33% (control: 642.40 ± 75.95; cKO: 452.20 ± 50.13 pixels per 30 s; P = 0.023), left chemotaxis normal, and reduced filopodia per cell by 46% (P < 0.01).
- Cyfip1-cKO microglia showed increased CD68 lysosomal burden (control: 4.25 ± 0.58%; cKO: 7.49 ± 0.29%; P < 0.001), increased lysosome number relative to cell size (control: 0.025 ± 0.003; cKO: 0.042 ± 0.004; P < 0.001), more Bassoon puncta within lysosomes (control: 0.19 ± 0.15; cKO: 1.32 ± 0.35 puncta/cell; P < 0.001), and increased pS6 intensity (P < 0.05).
Methods
- Two-photon live imaging of acute hippocampal slices from Iba1GFP mice measured spontaneous surveillance and chemotaxis toward a laser-induced lesion; slices were treated with CK666 (200 μM), cytochalasin D (10 μM), or vinblastine (10 μM).
- A microglia-specific inducible Cyfip1 cKO was generated by crossing Cyfip1F/F mice with Cx3cr1-CreERT2 and Iba1GFP lines; tamoxifen (4 mg oral) was given at P28 and P30, and experiments were performed at P44. Fixed brain sections were immunostained and 3D-reconstructed for morphology, lysosomes, Bassoon, and pS6.
- In vitro models included Cyfip1 siRNA knockdown in BV2 microglial cells and Cyfip1 conditional knockout MEFs; readouts included Western blot, phalloidin/DNAse1 staining, F/G-actin ratio, and cell morphology. Statistical analysis used linear mixed-effects models with animal or slice as variance components, plus t tests or ANOVA with Bonferroni correction for cell-culture experiments.
Limitations
- Stated: it is unclear whether increased synaptic material in lysosomes reflects increased phagocytic uptake or reduced degradation, and it is unclear how CYFIP1 loss increases mTORC1 activity in microglia, which is opposite to prior neuronal findings.
- Stated/evident: the cKO model is microglia-specific but tamoxifen-induced and achieved only approximately 50% reduction of CYFIP1 in enriched microglial lysates, not complete deletion; BV2 and MEF in vitro models may not fully capture in situ microglial biology.
- Evident: Arp2/3 dependence was tested pharmacologically with CK666, which may have off-target effects, and some live-imaging chemotaxis experiments used small animal numbers (e.g., N = 2 animals, 6 lesions for CK666 chemotaxis), limiting statistical power.

Fig. 4 title reverses the reported direction of synaptic cargo
MinorThe figure title says synapse engulfment is decreased, but the paper reports more presynaptic Bassoon within cKO microglial lysosomes and describes this as increased synaptic phagocytosis.

“As expected based on the enlarged lysosomes, Cyfip1-cKO microglia had significantly more Bassoon within their lysosomes (Fig. 4 K–L, P < 0.001).”
Two incompatible P-values are given for Fig. 4L
MinorThe same Bassoon-puncta comparison is labeled both P < 0.001 and P = 0.018 in the Fig. 4L caption.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-27.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-27.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
