Deciphering strategic interactions between mitochondrial and nuclear genome
Dr. José Antonio Enríquez from Centro Nacional de Investigaciones Cardiovasculares Carlos III, Spain. Dr. Enríquez will give a presentation entitled "Deciphering strategic interactions between mitochondrial and nuclear genome".
Dr. Enríquez has done probably the most advanced studies on nuclear-mitochondrial interactions and their effect on organisme longevity and health. He focuses on distinct combinations of nuclear and mitochondrial genomes and their effect at the organismal level (lifespan, health condition, predisposition to disease), as well as investigates the underlying mechanism including respiratory complexes and supercomplexes.
Last year he published a seminal paper in Science Advances showing the dynamics of non-pathogenic heteroplasmy (segregation of one of the two mtDNA genomes in different tissues) and their dependence on OXPHOS performance (PMID: 32832682). See also a recent review (PMID: 33369015) on the interactions between mitochondrial and nuclear genome.
Heteroplasmic mouse models harboring in the same cytoplasm, different non‐pathological mtDNA variants‐haplotypes. MtDNA preference is cell‐type‐specific and not tissue‐specific. Also, the metabolic differentiation program determines the preferred mtDNA haplotype and the mtDNA segregation is driven by functional selection and strongly modulated by the crosstalk between the nucleus and mitochondria. © 2020 The Authors.

Mitochondrial Arginase-2 is Essential for IL-10 Metabolic Reprogramming of Inflammatory Macrophages
Dr. Claire McCoy from Royal College of Surgeons in Ireland, Ireland will join the Targeting Mitochondria 2021 Congress and give a presentation about "Mitochondrial Arginase-2 is Essential for IL-10 Metabolic Reprogramming of Inflammatory Macrophages".
Dr. Claire McCoy graduated in Biochemistry from Trinity College Dublin and completed her PhD at the University of Dundee, Scotland in 2006. Her first postdoctoral position in Innate Immunology was completed at Trinity College Dublin, during which time she was awarded a prestigious Marie Curie International Fellowship. She joined the Hudson Institute, Melbourne as a Research Fellow in 2010 and obtained a New Investigator Project Grant from the NHMRC to continue her work investigating the role of microRNAs in Inflammatory diseases. Claire joined RCSI as the Immunology lecturer in August 2016, where she now leads the growing microRNA Inflammation research group. Claire was the recipient of an SFI Future Research Leader's award presented by President Higgins in January 2018.

Cardiorespiratory Fitness and Mitochondrial Health as Modulators of COVID-19
Dr. Johannes Burtscher, from University of Lausanne, Suisse will join the Targeting Mitochondria 2021 Congress and will give a presentation entitled "Cardiorespiratory Fitness and Mitochondrial Health as Modulators of COVID-19".
Dr. Burtscher confirms that some coronaviruses like SARS-CoV-2, the pathogen causing COVID-19, manipulate host cell mitochondria to dodge the host immune defense. We hypothesize that good mitochondrial health, for example due to regular exercise and associated with cardiorespiratory fitness, protects from viral manipulation of mitochondria. Conversely, mitochondrial damage may facilitate viral infection and aggravate the disease. I will summarize the theoretical interactions of SARS-CoV-2 with host mitochondria and provide an overview of recent studies investigating the link between COVID-19 and cardiorespiratory fitness and mitochondrial health.

Mechanism of Membrane-Tethered Mitochondrial Protein Synthesis
Dr. Antoni Barrientos from University of Miami Miller School of Medicine, USA will give a presentation entitled "Mechanism of Membrane-Tethered Mitochondrial Protein Synthesis".
The main research interest of their laboratory is on the basic mechanisms that govern the biogenesis of mitochondrial protein complexes in health, disease and aging. They are most specifically interested in the assembly and function of the mitochondrial translation machinery and of the mitochondrial respiratory chain and oxidative phosphorylation system components, involved in biological energy transduction.
The study of mitochondria is now a very “hot issue” for both basic and clinical research. Mitochondria are not only the “energy factories” of the cell but they also house a multiplicity of pathways that serve to regulate cellular life and death. Importantly, mitochondria are involved in prevalent human diseases of wide social impact, most notably neurodegenerative disorders, but also in cancer and the aging process.

Mitochondrial Transplantation Therapy, the Recent Advances and Perspective
Dr. James McCully, from the Harvard Medical School Department of Cardiac Surgery Boston Children’s Hospital, USA, will be joining the Targeting Mitochondria 2021 World Congress, which will be held October 27-29, 2021.
Dr. McCully will present his recent study on "Mitochondrial Transplantation Therapy, the Recent Advances and Perspective" during the congress.
Dr. McCully’s research focuses on the mechanisms and subcellular localization of the biochemical and molecular events contributing to myocardial cell death. In particular, his lab has investigated the discriminant and/or coordinate mechanisms leading to ischemia/reperfusion injury in the neonate, child, mature and aged male and female with particular emphasis on the development of novel and specific cardioprotective protocols.
Recently he has developed a novel approach to cardioprotection using autologous mitochondrial transplantation. His research has demonstrated that transplantation of autogeneic mitochondria into the ischemic zone of the myocardium during early reperfusion significantly enhances post-ischemic functional recovery.
