Figure 2(A, B) Microglia isolated from newborn Becn1+/- and wild type mouse pups were either non treated or treated with a pro-inflammatory stimulus (LPS followed by ATP). As additional controls cells treated only with LPS or ATP were used in (A). The concentration of the pro-inflammatory cytokines IL-1beta (A) and IL-18 (B) in the cell supernatant was determined by ELISA. Reduction of BECN1 significantly enhanced release of both cytokines after stimulation with LPS/ATP; mean ± SEM, wild type n (A/B) = 9/2, wild type LPS n = 3/0, wild type ATP n = 3/0, wild type LPS/ATP n = 9/9, Becn1+/- n = 23/5, Becn1+/- LPS/ATP n = 23/23, two-tailed t-test *: p < 0.05. (C) Microglia isolated from wild type mouse pups were pre-incubated in full medium or starvation medium HBSS before addition of a pro-inflammatory stimulus (LPS followed by ATP). The autophagy blocker 3-MA was added for the final 1 h 45 min of the experiment. The concentration of the pro-inflammatory cytokine IL-1beta in the cell supernatant was determined by ELISA. Incubation with HBSS reduced IL-1beta release significantly while 3-MA treatment increased it; mean ± SEM, full medium n = 6, full medium LPS/ATP n = 6, full medium LPS/ATP + 3MA n = 3, HBSS n = 6, HBSS LPS/ATP n = 6, HBSS LPS/ATP + 3MA n = 6; two-tailed t-test *: p < 0.05; **: p < 0.01. (D) Microglia isolated from wild type mouse pups were pre-incubated in starvation medium HBSS before addition of a pro-inflammatory stimulus (LPS followed by ATP).

Representative images show a reduction of LC3-positive vesicles in 3-MA treated cells. Scale bar: 20 µm. (E) Proteins were extracted from brains of wild type, Becn1+/-, APPPS1 and APPPS1 Becn1+/- mice at the indicated ages. IL-1beta was measured by electrochemiluminescence (MesoScale) and compared within the repective age groups. IL-1beta was significantly increased in the TBS and TX fraction; mean ± SEM, wild type: n (per age group) = 2/6/3, Becn1+/-: n = 2/5/2, APPPS1: n = 5/5/6, APPPS1 Becn1+/-: n = 7/9/6; ANOVA with Dunnett´s post hoc test with WT as control group; *: p < 0.05; **: p < 0.01. (F) Proteins were extracted from brains of APPPS1 and of APPPS1 Becn1+/- mice at the age as indicated. Amyloid beta 1-40 and 1-42 were measured by electrochemiluminescence (MesoScale) and compared within the repective age groups. No difference in the amyloid beta load between the genotypes is apparent; mean ± SEM, APPPS1: n = 5/5/6, APPPS1 Becn1+/-: n = 7/9/6; ANOVA with Dunnett´s post hoc test with APPPS1 as control group, ns.

PB1 deletion (ΔPB1) mutant, which is impaired in p62 oligomerization, is included as a control. TCL, total cell lysates. B Dimerization of p62 is enhanced in the MOAP-1 deficient cells. WT and MOAP-1 KO LO2 cells were transfected with plasmids encoding Flag-tagged and Myc-tagged p62 or empty vector. 24 h post-transfection, cells were harvested, lysed and the cell lysates were subjected to co-IP assay with anti-Myc antibody.D Re-expression of MOAP-1, but not the p62-binding defective mutant, MOAP-1-M3, reduces p62 oligomerization in the MOAP-1 KO LO2 hepatocytes. WT and MOAP-1 KO LO2 cells were transfected with plasmids encoding His-tagged p62 and Myc-MOAP-1 or Myc-MOAP-1-M3 and 24 h later, subjected to His-pull down and cross-linking using DSSO.F The region of p62 spanning the PB1 and ZZ domains are required for mediating its interaction with MOAP-1. p62 KO LO2 cells were used in the analysis.

a) The accumulation of the Atg3–GL1 conjugate depends on the extent of membrane curvature.figf4(a) The accumulation of the Atg3-GL1 conjugate depends on the extent of membrane curvature. In vitro GL1 coupling reactions were run as in Fig. 1. The reactions were visualized by immunoblot against Atg3 (top) and by Coomassie staining of GRL1 (bottom). The accumulation of Atg3-GL1 is inversely related to the formation of the lipidated GRL1, suggesting that the membrane-curvature-dependent step may involve Atg3 recognition of the membrane surface. (b) Atg3 binding to liposomes. Atg3 (10 μM) was incubated at 30 °C for 90 min with liposomes containing 0, 30 or 55 mol% DOPE (5 mM lipids) and of varying sizes (extrusion membrane dimensions are shown on the figure; actual final sizes were determined by dynamic light scattering (Supplementary Table 1)). The liposome-associated Atg3 was recovered by Nycodenz density gradient centrifugation and analysed by SDS-PAGE. (c) Quantification of liposome-associated Atg3.
