News & Events: Tobias Deuse, M.D.

Cardiac and heart/lung transplant surgeon-scientist Tobias Deuse, M.D. has been awarded a 4-year $400K grant from the National Science Foundation (NSF) to investigate space-related physiological changes in liver aging and regeneration. The work will be carried out aboard the International Space Station (ISS) using a novel platform, tissue engineered liver immune chips in microgravity. Dr. Deuse is Professor and Interim Chief of the Division of Adult Cardiothoracic Surgery, and Director of Minimally-Invasive Cardiac Surgery at UCSF. He is also a principal investigator in the Transplant and [...]

Mutations in Mitochondrial DNA Induced by Cell Reprogramming May Trigger Immune Response In 2006, scientists discovered a way to "reprogram" mature cells – adult skin cells, for example – into stem cells that could, in principle, give rise to any tissue or organ in the body. Many assumed it was only a matter of time until this groundbreaking technique found its way into the clinic and ushered in a regenerative medicine revolution. Because the same patient would be both the donor and the recipient of cells derived from these so-called induced pluripotent stem cells (iPSCs), these cells [...]

Tobias Deuse, MD, Professor of Surgery at UCSF, and a cardiac and heart transplant surgeon internationally renowned for his pioneering work in the development of minimally-invasive techniques for mitral valve repair, discusses the advantages of minimally invasive approaches for the treatment of mitral valve insufficiency, describing the operative technique, which candidates and pathologies are the best candidates for this procedure, and the importance of volumes and experience in achieving optimal outcomes.

Technique Prevents Transplant Rejection in the Lab, a Major Advance for Stem Cell Therapies  Human heart muscle cells derived from triple-engineered stem cells that are "invisible" to the immune system. The red is troponin, a protein that participates in cardiac muscle contraction. The blue is the cell's nucleus. Researchers hope cells like these will eventually be used to treat heart failure. Credit: Xiaomeng Hu. UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally "invisible" to the immune system, [...]

Sonja Schrepfer, M.D., Ph.D. and Tobias Deuse, M.D. have been awarded a 4-Year $3M NIH R01 Grant to study the role of cardiomyocytes in heart repair. Dr. Schrepfer is an associate professor and director of the UCSF Transplant and Stem Cell Immunobiology (TSI) Lab. Dr. Deuse, a renowned heart surgeon, is associate professor and director of minimally-invasive cardiac surgery at UCSF and a principal investigator in the TSI lab.  The study will generate hypo-immunogenic cardiomyocytes that could be used therapeutically for regenerating tissues but are engineered to avoid rejection by patients [...]

Sonja Schrepfer, M.D., Ph.D. and Tobias Deuse, M.D. have been awarded a 4-year $2.4M NIH grant by the National Center for Advancing Translational Sciences (NCATS) to investigate space-related physiological changes, analogous to those observed during aging, including defects in bone healing, loss of cardiovascular and neurological capacity, and altered immune function. Dr. Schrepfer is associate professor and director of the UCSF Transplant and Stem Cell Immunobiology (TSI) Lab. Dr. Deuse is associate professor and director of minimally-invasive cardiac surgery at UCSF. He is also [...]

Tobias Deuse, M.D., associate professor of surgery and director of minimally-invasive cardiac surgery at UCSF, has been named The Julien I. E. Hoffman, M.D. Chair in Cardiac Surgery. Dr. Deuse, a cardiac and heart transplant surgeon, is internationally renowned for his pioneering work in the development of minimally-invasive techniques for mitral and aortic valve repair, demonstrating high success rates in mitral valve repair utilizing robotic-assisted (fully) endoscopic surgery or "keyhole surgery". Dr. Deuse is also a principal investigator in the Transplant and Stem Cell Immunobiology [...]

Dr. Tobias Deuse was recruited to UCSF from the University of Hamburg-Eppendorf, one of the leading mitral valve centers in Germany. He is excited by UCSF's team approach to complex heart disease, and recently led the establishment at UCSF of a combined clinic where patients see both an interventional cardiologist and cardiac surgeon on the same day; the specialists then consult with each other and tailor a treatment plan for each patient's unique situation. If patients meet with a doctor who tells them one thing, and then the next doctor tells them something completely different, they go [...]

UCSF News reports on research into the effects of space travel, known and unknown, to the physiology and bodies of astronauts traveling about the international space station (ISS). The research has profound implications for longer trips to distant planets, notably NASA's goal of flying a manned spacecraft to Mars. Research into the novel and myriad effects of space travel on humans will be critical to the success of this endeavor. Three faculty in the UCSF Department of Surgery and an esteemed collaborator in the Department of Biochemistry and Biophysics, were among the researchers [...]

Sonja Schrepfer, M.D., Ph.D., Associate Professor and Director of the UCSF Transplant and Stem Cell Immunobiology (TSI) Lab, was recently awarded a grant  by the California Institute for Regenerative Medicine (CIRM) to engineer a "Hypo-Immunogenic Cardiac Patches for Myocardial Regeneration". The funding is part of CIRM's Discovery: Inception program is for seed funding for great ideas that have the potential to impact human stem cell research, funding that will enable the researchers to test their ideas, and generate preliminary data to support for greater funding. Dr. Schrepfer proposed [...]

The Transplant and Stem Cell Immunobiology (TSI) Lab at UCSF has officially launched its new website. Its two principal investigators, Sonja Schrepfer, M.D., Ph.D., Lab Director and Associate Professor of Surgery, and Tobias Deuse, M.D., Associate Professor of Surgery and Director of Minimally Invasive Cardiac Surgery, both of the Division of Adult Cardiothoracic Surgery, conduct research to answer complex questions about stem cell therapy, heart and lung transplantation, and cardiovascular disease, with the goal of translating basic science discoveries into downstream medical [...]
