Control (WT), Atg16L1-/- and ATG16L1-/- MEFS expressing truncated TECPR1* were incubated for 2 hours in nutrient media containing chloroquine (100 µM). Panel A. Cells were fixed and immunostained for ATG5 (red) and galectin-3 (green). Panel B. Cells were fixed and immunostained for ATG5 (red) and LC3 (green). Panel C. Quantification and composition of puncta positive for ATG5 and galectin 3. Panel D. Quantification and composition of puncta positive for ATG5 and LC3. n ≥ 30 cells were quantified by Imaris, P-values were calculated using multiple t-test (****P < 0.0001). Scale bar 5 μm. Panel E. ATG16L1-/- MEFS expressing GFP-lysenin (green) and TECPR1-RFP (red) were incubated in nutrient media containing chloroquine (200 µM) for 30 minutes. Scale bar 5 μm.

    Article Snippet: The majority (85%) of the PI4P/galectin-3 positive puncta also contained ATG5 ( ) suggesting recruitment of the ATG5-ATG12 complex required to conjugate LC3 to membranes.

    Recruitment of galectin-3 and GFP-lysenin to lysosomes correlates with release of dextran. ATG16L1-/- MEFS expressing GFP-lysenin were cultured in Dextran-Red R (300 mg/ml) to label lysosomes and incubated with chloroquine (200 µM) for 10 or 30 minutes as indicated. Images show distribution of GFP-lysenin, Dextran-Red R and galectin-3 (far red). Asterisks indicate puncta positive for lysenin and galectin-3 that are negative for dextran.

    Analysis of LC3 and galectin-3 distribution on damaged lysosomes by structured illumination microscopy: MEFs were incubated nutrient media containing chloroquine (100 µM) for 2 hours and then stained with DAPI (cyan) and immunostained for LC3 (yellow) and galectin3 (magenta) and imaged by 3D-SIM. Panel A: control MEFS. A swollen vacuole (I) recruits LC3 (I-i, maximum intensity projection-MIP) but not galactin3. To visualise this better, using Imaris, a 3D rendered surface was applied (I-ii) and then bisected (I-iii) showing the hollow vacuole interior. Analysis of small dense puncta (II) shows that LC3 (II-i, yellow MIP) and galectin3 (II-ii, magenta MIP) are recruited together as seen in the coloured overlay (II-iii). A 3D rendered surface (II-iv) bisected (II-v) shows the densely packed interior of this puncta. Scale bar = 1 µm. Panel B: ATG16L1-/- MEFs. Analysis of small dense puncta shows that LC3 (i, yellow MIP) and galectin3 (ii, magenta MIP) are recruited together as seen in the coloured overlay (iii). A 3D rendered surface (iv) bisected (v) shows the densely packed interior of the puncta. Scale bar = 1 µm.
