Left axis: diameter of largest microglial phagosome in barrel cortex from Ifnar1+/+ and Ifnar1-/- mice, P5. Violin plots show line at mean, and dots show individual microglia. Right axis: mean diameter of microglial nuclei (n = 57–76 microglia from 3 mice per group). Bubble microglia defined as those with phagosomes larger than mean nucleus diameter.
