Fig. 2 bubblebrain Functions Downstream of Cell Death and Engulfment
(A and B) Dorsal view of blbNY007; Tg(spi1b:Gal4,UAS:GFP); Tg(NBT:DsRed) (A) and blbNY007; Tg(spi1b:Gal4,UAS:GFP); Tg(NBT:DsRed) injected with a Caspase 3 morpholino and treated with Z-VAD to reduce apoptosis (B); representative images quantified in (G).
(C and D) Microglial cells labeled with Tg(spi1:Gal4,UAS:GFP) in 4 dpf blbNY007 (C) and in blbNY007 injected with morpholinos against BAI1 and TIM-4 to reduce engulfment (D); representative images quantified in (H).
(E and F) Representative examples of trunk 4 dpf macrophages in blbNY007 (E) and blbNY007 treated with Camptothecin to increase apoptosis (F). Scale bar 10 μm.
(G) Quantification of (A) and (B). Number of microglia with bubble morphology in blbNY007 (n = 61) and blbNY007 with reduced apoptosis (n = 61). Whiskers: 5th/95th percentile, p value < 0.0001.
(H) Quantification of (C) and (D). Number of microglia with bubble morphology in blbNY007 (n = 50) and blbNY007 injected with Tim4+BAI1 morpholino to reduce engulfment (n = 50). Whiskers: 5th/95th percentile, p value < 0.0001.
(I) Electron micrograph of a representative blbNY007 microglia at 3 dpf. Scale bar, 5 μm.
