We here identify the endosomal protein SNX10 as a negative regulator of piecemeal mitophagy OXPHOS machinery components. In control conditions, localizes to early endocytic compartments in PtdIns3P-dependent manner and modulates trafficking but also shows dynamic connections with mitochondria. Upon hypoxia-mimicking late structures containing selected mitochondrial proteins, including COX-IV SAMM50, autophagy proteins SQSTM1/p62 LC3B. The turnover was enhanced SNX10-depleted cells, corresponding reduced respiration citrate synthase activity. Importantly, zebrafish larvae lacking Snx10 show levels Cox-IV, well elevated ROS ROS-mediated cell death brain, demonstrating vivo relevance SNX10-mediated modulation bioenergetics.

Abstract Lipid droplets (LDs), which are active organelles, derive from the monolayer membrane of endoplasmic reticulum and encapsulate neutral lipids internally. LD-associated proteins like RAB, those in PLIN family, CIDE family participate LD formation development, they players various diseases, metabolic processes (i.e., obesity, non-alcoholic fatty liver disease, autophagy). Our synthesis on existing research includes insights LDs to their mechanisms action, provide an overview needed for advancing into diseases lipid metabolism.

Abstract Sepsis is a life-threatening multi-organ dysfunction syndrome caused by dysregulated host response to infection, posing significant global healthcare challenge. Sepsis-induced myocardial (SIMD) common complication of sepsis, significantly increasing mortality due its high energy demands and low compensatory reserves. The substantial mitochondrial damage rather than cell apoptosis in SIMD suggests disrupted cardiac metabolism as crucial pathophysiological mechanism. Therefore, we systematically reviewed the mechanisms underlying SIMD, including alterations substrates, excitation–contraction coupling processes, dysfunction, autophagy biogenesis, summarizing potential therapeutic targets within them.

Background and Aims: Plasma interleukin (IL)-27 is an important mediator of acute hepatic injury (AHI) associated with sepsis. Mitochondria contribute to the proper regulation macrophage phagocytosis. In this study, we investigated effect IL-27 on mitochondrial function antimicrobial response macrophages in sepsis-associated AHI. Methods: Wild-type (WT) receptor WSX-1 deficient (IL-27R-/-) mice underwent cecal ligation puncture (CLP). The severity injury, inflammatory cytokine levels, pyroptosis, bacterial load liver blood were assessed 24 h after CLP. vitro, RAW264.7 cells peritoneal treated lipopolysaccharide (LPS) and/or IL-27. phagocytosis killing functions detected. Mitochondrial mitophagy detected using western blot, glutathione (GSH)/malondialdehyde (MDA) content measurement, fluorescence staining, JC-1 staining vivo vitro. After treatment nicotinamide mononucleotide (NMN, NAD + precursor), a pharmacologic agent that improves function, response, pyroptosis assessed. Results: IL-27R-/- exhibited marked reduction (based cleaved GSDMD Caspases 1 protein levels), systemic inflammation serum IL-6, IL-10, TNF-α levels) compared WT following CLP, lacking IL-27R displayed significantly higher clearance greater local infection control.

Abstract Toll-interacting protein (Tollip) is an intracellular adaptor with diverse functions including regulation of autophagy mitochondria—mitophagy. Tollip deficiency promotes viral infection, but whether mitophagy involved remains unclear. We sought to determine if and associated signaling such as mitochondrial DNA (mtDNA) release activation stimulator interferon genes (STING) contribute worsened infection due deficiency. Wild-type knockout (KO) C57/BL6 mice were intranasally infected influenza A virus (IAV), then treated or without a STING agonist 2′3′cGAMP for 4 d. PINK1 (an initiator mitophagy) KO mouse tracheal epithelial cells (mTECs) IAV reveal the role in infection. In IAV-infected mice, enhanced lung (more BNIP3L, less p62), decreased mtDNA. Furthermore, suppressed antiviral response (eg IFN-β MX1), increased load. activated coupled virus.
