doi: 10.1042/CS20257026

Figure Lengend Snippet: A . LC3-II or LC3-I/II ratio was altered in hChAT KO mouse hearts, associated with the up-regulation of p62 and nitrotyrosine protein expression. B , Protein levels of both Parkin (PRK) and PINK1 were altered reciprocally between cytosolic and mitochondrial fractions of hChAT KO mouse hearts, compared with control mouse hearts. The hChAT KO reduced PRK and PINK1 protein levels in the cytosolic fraction ( P <0.05 and P <0.05, respectively), however alternatively, their levels both increased in the mitochondrial fractions ( P <0.01 and P <0.01, respectively).

Article Snippet: Furthermore, proteins from mitochondrial or cytosol fraction were subjected to western blot analysis using a rabbit anti-PARK2/Parkin polyclonal antibody (1:1000, #14060–1-AP; Proteintech), rabbit anti-PINK1 polyclonal antibody (1:1000, #23274–1-AP; Proteintech), rabbit anti-GAPDH monoclonal ab (Cell Signaling Technology), and rabbit anti-VDAC polyclonal ab (Abcam).

Figure Lengend Snippet: Decreased MIC60 immunosignals in the OPL of MOG/CFA-injected mice in comparison to CFA-injected mice at day 9 post-injection. The 0.5 µm- thin retina sections from MOG/CFA-injected EAE mice ( B1 – B3 , D1 – D3 , F1 – F3 ) and CFA-injected control mice ( A1 – A3 , C1 – C3 , E1 – E3 ) double-immunolabelled with rabbit polyclonal MIC60 antibody (green channel) and mouse monoclonal RIBEYE antibody (red channel). Signals from the green ( A1 , B1 , C1 , D1 , E1 , F1 ) channels and red channels ( A2 , B2 , C2 , D2 , E2 , F2 ) were merged in ( A3 , B3 , C3 , D3 , E3 , F3 ). ( A1 – B3 ) Representative low-magnification images. Low-magnification micrographs show MIC60-labelled mitochondria in the OPL and in the photoreceptor inner segments in the same section. ( C1 – D3 ) MIC60-positive mitochondria in the OPL close to the synaptic ribbon at intermediate magnification. ( E1 – F3 ) High-magnification confocal images of single immunolabelled synaptic mitochondria in the OPL. Ring-like MIC60 immunosignals of individual presynaptic mitochondria are visible close to the synaptic ribbons (arrows). Ribbons appear as single horseshoe-labelled structures (arrowheads). ( G1 , G2 , H1 , H2 ) MIC60 immunosignals from the OPL and IS were quantified as integrated density. ( G1 , H1 ) Bar graphs depict normalized arithmetic means ± S.E.Ms. MOG/CFA integrated density immunofluorescence values were normalized to the mean of the CFA control values (set to 100%). In ( G2 , H2 ), the same data as in ( G1 , H1 ) are depicted as box-and-whisker plots to show the individual datapoints and their distribution. ( G2 , H2 ) Boxes represent 25th–75th percentiles of the data points, mean and median values are indicated by thin and thick horizontal lines, respectively, and whiskers are equal to 1.5 times the interquartile range (IQR). Mann–Whitney U-test was conducted to determine if there were significant differences in MIC60 immunosignals in the OPL between CFA and MOG/CFA groups. The distributions significantly differed between both groups (effect size d = 1.0751; power = 0.9999). MIC60 immunosignals in the inner segments did not differ between both groups (effect size d = 0.1497; power: 0.1517). p -values < 0.05 were considered statistically significant.

The 0.5 µm thin retina sections immunolabelled with rabbit polyclonal MIC60 antibody ( A1 , B1 ) and with mouse monoclonal RIBEYE antibody ( A2 , B2 ). Overlay images are shown in ( A3 , B3 ). Highly magnified confocal images of the immunolabelled OPL (A1-B3) were used for the quantification of RIBEYE puncta ( C1 , C2 ) and MIC60 puncta ( C3 , C4 ). ( D1 , D2 ) Quantification of MIC60 fluorescence intensities of each single MIC60-positive synaptic mitochondrion close to rod synaptic ribbons, measured as integrated density. ( C1 , C3 , D1 ) Bar graphs depict normalized arithmetic means ± S.E.M. In ( C2 , C4 , D2 ), the individual data from ( C1 , C3 , D1 ) are depicted as box-and-whisker plots. Boxes represent 25th–75th percentiles; the mean and median values are indicated by thick and thin horizontal lines, respectively. Whiskers are equal to 1.5 times the interquartile range (IQR). Unpaired Student’s t -test was conducted to determine if there were significant differences in RIBEYE puncta in the OPL between CFA and MOG/CFA groups. The distributions did not differ significantly between both groups (effect size d = 0.2738, power = 0.4827). To determine differences in MIC60 puncta between both groups the Mann–Whitney U-test was conducted and showed significant difference between both groups (effect size d = 1.8338; power =1.0). Differences in MIC60 expression in individual mitochondria were evaluated with Mann–Whitney U-test. Analysis revealed significant differences between the CFA and MOG/CFA groups (effect size d = 0.7443; power = 1.0). Data were considered statistically different with p < 0.05.

Figure Lengend Snippet: Decreased expression of the mitochondrial ATP5B synthase subunit of the F 1 F 0 ATP synthase complex in synaptic mitochondria of photoreceptor synapses in MOG/CFA-injected EAE retinas at day 9 post-immunization. The 0.5 µm thin retina sections from CFA-injected mice and MOG/CFA-injected mice were incubated with mouse monoclonal ATP5B antibody ( A1 , B1 , C1 , D1 ) and with rabbit polyclonal monoclonal antibodies against RIBEYE (U2656) ( A2 , B2 , C2 , D2 ), as indicated. Overlay images are shown in ( A3 , B3 , C3 , D3 ). ( A1 – A3 , B1 – B3 ) show representative low-magnification micrographs of the photoreceptor compartments from MOG/CFA- and CFA-injected mice. The immunolabelled OPL is magnified in ( C1 – C3 , D1 – D3 ). ( E1 , E2 ) ATP5B immunosignals from the OPL were quantified as integrated density from 5 different littermate mice at day 9 post-injection.

Figure Lengend Snippet: Decreased expression of the mitochondrial COX1 protein in synaptic mitochondria of photoreceptor synapses in MOG/CFA-injected EAE retinas at day 9 post-immunization. The 0.5 µm thin retina sections from CFA-injected mice and MOG/CFA-injected mice were incubated with rabbit polyclonal antibody against COX1 ( A1 , B1 , C1 , D1 ) and with mouse monoclonal antibody against RIBEYE (2D9) ( A2 , B2 , C2 , D2 ), as indicated. Overlay images are shown in ( A3 , B3 , C3 , D3 ). ( A1 – A3 , B1 – B3 ) show low-magnification micrographs of the photoreceptor compartments. The immunolabelled OPL is magnified in ( C1 – C3 , D1 – D3 ). ( E1 , E2 ) COX1 immunosignals from the OPL were quantified as integrated density from 5 different littermate mice at day 9 post-injection.

( E2 ) Boxes represent 25th–75th percentile of the data points, and mean and median values are indicated by thick and thin horizontal lines, respectively. Whiskers are equal to 1.5 times the interquartile range (IQR). Comparison of COX1 expression between control and experimental groups using a Mann–Whitney U-test revealed significant reduction in COX1 expression in the OPL of MOG/CFA-injected animals (effect size d = 1.2242; power = 1.0). p -values < 0.05 were considered statistically significant.

Figure Lengend Snippet: Strong decrease in Pink1 immunosignals in the OPL of MOG/CFA-injected mice in comparison to CFA-injected control mice on day 9 post-injection. The 0.5 µm-thin retina sections from both groups (i.e., CFA ( A1 – A3 ) and MOG/CFA ( B1 – B3 )) were double-immunolabeled with rabbit polyclonal antibody against Pink1 ( A1 , B1 ) and mouse monoclonal antibody against RIBEYE (2D9) ( A2 , B2 ). Signals from the green ( A1 , B1 ) and red ( A2 , B2 ) channels were merged in ( A3 , B3 ). The double-immunolabelling data demonstrate that Pink1 puncta are located close to the RIBEYE puncta ( A3 , B3 ). ( C1 , C2 ) Quantification of the Pink1 immunosignals in the OPL. Column plots in ( C1 ) show normalized arithmetic mean fluorescence values (integrated densities) ± S.E.M. Pink1 immunosignals in the OPL of MOG/CFA-injected mice were normalized to the arithmetic mean of the values from CFA-injected control mice (that was set to 100%). The Mann–Whitney U-test was used to determine whether Pink1 is significantly altered in MOG/CFA-injected animals in comparison to CFA-injected control animals because data were non-normally distributed (effect size d = 1.1445; power = 1.0). p -values < 0.05 were considered statistically significant. The same data as shown in ( C1 ) are also depicted as box-and-whisker plots in ( C2 ) to show the individual datapoints. Boxes represent the 25th–75th percentile of the data points.

DRP1 immunosignals in the OPL of MOG/CFA-injected mice were normalized to the arithmetic mean of the values from CFA-injected control mice (that was set to 100%).
