    Intrinsic Cardiac Adrenergic Cells Contribute to LPS-Induced Myocardial Dysfunction

    Scientists showed that norepinephrine secretion from intrinsic cardiac adrenergic cells was increased through activation of Toll-like receptor 4 to aggravate myocardial TNF-α production and dysfunction by lipopolysaccharide.

    Modulation of miR-145-5p and miR-146b-5p Levels Is Linked to Reduced Parasite Load in H9C2 Trypanosoma cruzi Infected Cardiomyoblasts

    Researchers explored the effects of interventions with the trypanosomicidal drug benznidazole alone or combined with pentoxifylline, a methylxanthine derivative shown to modulate immunological and cardiac abnormalities in a model of chronic chagasic cardiomyopathy, on parasite load and expression of miR-145-5p and miR-146b-5p.

    Mechanism of miR-378a-3p Enriched in M2 Macrophage-Derived Extracellular Vesicles in Cardiomyocyte Pyroptosis after MI

    An in vitro cell model was established, followed by a comprehensive evaluation of cell viability and pyroptosis. The binding relationships of miR-378a-3p and ELAVL1, HuR, and NLR family pyrin domain containing 3 were analyzed.

    Abstract

    Influence of Adiponectin and Inflammatory Cytokines in Fatty Degenerative Atrophic Muscle

    In vitro and in vivo experiments showed that the expression of adiponectin was decreased and the expression of Il6 and Tnf was increased in the nerve-crushed group compared to that in the control group.

    Scinderin Promotes Fusion of Electron Transport Chain Dysfunctional Muscle Stem Cells with Myofibers

    Scientists reported here that in response to mitochondrial reactive oxygen species, murine muscle stem cells (MuScs) directly fused with neighboring myofibers; this phenomenon removed electron transport chain-dysfunctional MuSCs from the stem cell compartment.

    Ubiquitinated AIF Is a Major Mediator of Hypoxia-Induced Mitochondrial Dysfunction and Pulmonary Artery Smooth Muscle Cell Proliferation

    The authors investigated the specific involvement of apoptosis-inducing factor, a mitochondrial oxidoreductase in regulating mitochondrial energy metabolism and mitophagy in pulmonary artery smooth muscle cells.
