For quantification, at least 3 mutant patches were quantified per eye imaginal disc, and at least 2 mutant patches were quantified per adult retina. At least three eye imaginal discs or adult retina derived from distinct flies were used (N=3). Error bars correspond to standard deviation (stdev). Significance was determined by Welch's t-test: ***p≤ 0.001, ****p ≤ 0.0001.

A subset of centrosomal proteins is shown as described in (Azimzadeh et al, 2012). Black bars represent the centrosome subset and red bars represent the values obtained by SRM. Results presented are means ± SEM.

G Proposed model for FBXO2-mediated recognition of bacterial glycan in xenophagy. GAS internalized via endocytosis enters the cytosol, and then GAS escapes into the cytoplasm by SLO secretion. Escaped GAS is targeted by FBXO2 via recognition of GlcNAc and is ubiquitinated by the SCF complex. Finally, LC3 is recruited to ubiquitinated GAS for autophagy formation.

Neurodegeneration by polyQ Atro partially requires dachs.Figure 7Neurodegeneration by polyQ Atro partially requires dachs. Tangential eye sections through dGC13 clones (marked by the absence of yellow pigment) either in control flies or those expressing Atro75QN with the Rhodopsin1 driver and aged 28 days. Mask panels below each section exemplify clonal boundaries and PR no. for the ommatidia.

Model for competition of mitochondrial precursor proteins and aggregation-prone proteins for factors of the quality control (QC) machinery, such as chaperones and components of the proteasome system. Our observations indicate that mitochondrial membrane proteins pose a particular threat to cytosolic proteostasis. Overexpression of the indicated components of the import machinery suppress the toxicity of polyQ proteins for which the prion protein Rnq1 plays a critical role.

Figure 7Percentage of phage particles in the extended, intermediate, and contracted states after 5, 20 and 80 minutes of incubation with L. monocytogenes cell walls. The numbers above the bars show the number of particles contained in the tomograms. The average length of the tail and the standard deviation for each of the three states is given next to the color legend. The color code for proteins that were located in A511 cryoEM maps (upper panels C, D, E, F) and their T4 orthologs. The pre-attachment state. Here and elsewhere in this figure, the EM image in the lower panel is a slice through the cryoET reconstruction. Note that in the presence of the Listeria cell wall the gp108 fibers are no longer in their stowed conformation but instead are fully or partially unraveled. Gp108 fibers attach to the host cell wall but the sheath is not yet contracted. RBP/TF gp106 (and possibly gp107) pyramids reorient to point toward the cell surface, change their conformation, and bind to the cell wall. The baseplate-proximal part of the sheath is in a contracted state, whereas the capsid-proximal part is still in an extended state. The baseplate-proximal part of the sheath contains a segment where the tail tube is clearly visible because it no longer interacts with the sheath (lower panel). The post-attachment state. The tail is fully contracted and the tail tube has pierced through the cell wall. The capsid appears full indicating that DNA injection has not yet begun.

TFEB promotes clearance of enlarged lysosomes and increases lysosomal motility in PD fibres.Figure 4A. Confocal microscopy images of live fibres derived from 3 to 4 month-old GFP-LC3:WT (top left), untreated GFP-LC3:GAA−/− (bottom left) or TFEB-treated GFP-LC3:GAA−/− (right) mice. All fibres were transfected with mCherry-LAMP1 to visualize lysosomes (red). The effects of TFEB are clearly visible - overall reduction in lysosomal size, appearance of normal size lysosomes (similar to those in the WT), and lysosomal docking to the plasma membrane (inset). Bar: 10 µm. B. FDBmuscle of a GAA−/− mouse was transfected with both GFP-TFEB and mCherry-LAMP1 (GAA−/− + GFP-TFEB). Images were taken before (left) and after 4 h (right) of time-lapse microscopy. Lysosomal clearance is visible in the TFEB-transfected fibre at both time points. Lysosomes appear to "exit" the fibre (inset and arrow) at the 4 h time point when TFEB is activated as evidenced by its nuclear translocation (green nuclei). Bar: 10 µm.C. The mean maximum velocity of lysosomes (top) and the number of large (>3.5 µm) lysosomes (bottom) in untreated and TFEB-treated PD fibres (note: all data for Flag- and GFP-TFEB-treated fibres are pooled). Lysosomal velocities were calculated from time-lapse images using ImageJ software with the manual tracking plug-in. For each condition the trajectories of multiple lysosomes were followed (n = 26 untreated; n = 43 TFEB-treated) and the three highest velocity measurements per lysosome were recorded. In TFEB-treated fibres, the maximum velocity of lysosomes was significantly increased (p = 2.07 × 10−17) and the number of large lysosomes was significantly decreased (p = 1.0 × 10−3). Ten untreated and 24 TFEB-treated fibres were analysed for the size calculations. * indicates statistically significant differences (p ≤ 0.001; Student's t-test). Error bars represent 95% confidence intervals.
