ABSTRACT Mitochondria are critical in the regulation of cellular metabolism and influence signaling processes and inflammatory responses. Mitochondrial DNA mutations and mitochondrial dysfunction are known to cause a wide range of pathological conditions and are associated with various immune diseases. The findings in this work describe the effect of a mutation in the mitochondrially encoded mt-Atp8 gene in the conplastic mouse strain C57BL/6J-mtFVB/NJ on the mitochondrial function and consequent alterations to metabolic and immunological phenotypes. This work provides insights into the mutation-induced cellular adaptations that influence the inflammatory milieu and shape pathological processes, in particular focusing on autoimmune bullous diseases, which have recently been reported to be associated with mtDNA polymorphisms in the human MT-ATP8 gene. The mt-Atp8 mutation diminishes the assembly of the ATP synthase complex into multimers and decreases mitochondrial respiration, affects generation of reactive oxygen species thus leading to a shift in the metabolic balance and reduction in the energy state of the cell as indicated by the ratio ATP to ADP. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

The The proteolytic processing of dynamin-like GTPase OPA1, mediated balance between long and short OPA1 forms is finely regulated by two by the activity of both YME1L1 [intermembrane (i)-AAA protease mitochondrial inner membrane proteases, OMA1 (Ehses et al., 2009) complex] and OMA1, is a crucial step in the regulation of mitochondrial and YME1L1, which cleave OPA1 at different sites (Song et al., 2007). dynamics. OMA1 is a zinc metallopeptidase of the inner mitochondrial The intermembrane (i)-AAA protease YME1L1 exposes its membrane that undergoes pre-activating proteolytic and auto- catalytic domain to the intermembrane space (Leonhard et al., 1996) proteolytic cleavage after mitochondrial import. Here, we identify and is responsible for generation of the S2-OPA1 form by proteolytic AFG3L2 [matrix (m)-AAA complex] as the major protease mediating cleavage, whereas OMA1 gives rise to the S1 and S3 forms (Anand this event, which acts by maturing the 60 kDa pre-pro-OMA1 to the et al., 2014; MacVicar and Langer, 2016; Quirós et al., 2012). 40 kDa pro-OMA1 form by severing the N-terminal portion without OMA1 harbours an M48 metallopeptidase domain and is the major recognizing a specific consensus sequence.

4-6 Weeks Old Female C57BL/6 Mice Obtained from Jackson Labs Were Used for Cell Isolation
Methods Mice: 4-6 weeks old female C57BL/6 mice obtained from Jackson labs were used for cell isolation. Female Foxp3-IRES-GFP reporter mice (1), backcrossed to B6/C57 background for 10 generations, were used for the isolation of naïve CD4 and naïve CD8 cells for the RNAseq experiments. The mice were housed in pathogen-free animal facility in the La Jolla Institute for Allergy and Immunology and were used according to protocols approved by the Institutional Animal Care and use Committee. Preparation of cells: Subsets of thymocytes were isolated by cell sorting as previously described (2), after cell surface staining using CD4 (GK1.5), CD8 (53-6.7), CD3ε (145- 2C11), CD24 (M1/69) (all from Biolegend). DP cells: CD4+CD8 int/hi; CD4 SP cells: CD4CD3 hi, CD24 int/lo; CD8 SP cells: CD8 int/hi CD4 CD3 hi, CD24 int/lo (Fig S2). Peripheral subsets were isolated after pooling spleen and lymph nodes. T cells were enriched by negative isolation using Dynabeads (Dynabeads untouched mouse T cells, 11413D, Invitrogen). After surface staining for CD4 (GK1.5), CD8 (53-6.7), CD62L (MEL-14), CD25 (PC61) and CD44 (IM7), naïve CD4+CD62L hiCD25-CD44lo and naïve CD8+CD62L hiCD25-CD44lo were obtained by sorting (BD FACS Aria). Additionally, for the RNAseq experiments, CD4 and CD8 naïve cells were isolated by sorting T cells from the Foxp3- IRES-GFP mice: CD4+CD62LhiCD25–CD44lo GFP(FOXP3)– and CD8+CD62LhiCD25– CD44lo GFP(FOXP3)– (antibodies were from Biolegend). In some cases, naïve CD4 cells were cultured in vitro under Th1 or Th2 polarizing conditions (3, 4). -
