  • Yusuke Nakauchi

    Yusuke Nakauchi

    Instructor, Institute for Stem Cell Biology and Regenerative Medicine

    Current Research and Scholarly InterestsFrom 2005 to 2010, my work as a clinical hematology fellow allowed me to experience first-hand how scientific advances that started in a laboratory can transform patients' lives. While many of my patients were cured of their disease with allogeneic hematopoietic stem cell transplantation, underscoring the importance of anti-tumor immunotherapy in eradicating leukemia, I witnessed face-to-face their suffering from the long-term consequence of graft-versus-host disease (GVHD). This experience was ultimately what drove me to engage in research to discover novel therapies. For this reason, I embarked on a Ph.D. program in 2010 to design antibody therapy to (i) target GVHD and (ii) target hematological malignancies. Under the mentorship of Professor Hiromitsu Nakauchi at the University of Tokyo, an international leader in hematopoiesis, I developed allele-specific anti-human leukocyte antigen (HLA) monoclonal antibodies for severe GVHD caused by HLA-mismatched hematopoietic stem cell transplantation (Nakauchi et al., Exp Hematol, 2015). This study was the first to find that anti-HLA antibodies can be used therapeutically against GVHD. That success gave me the motivation and confidence to further my research beyond targeting GVHD to targeting leukemic stem cells through my postdoctoral fellowship in the laboratory of Professor Ravindra Majeti here at Stanford University.

    Many people suffer from leukemia each year, but we still don't know how to cure it completely. Recent advances in sequencing technologies have tremendously improved our understanding of the underlying mutations that drive hematologic malignancies. However, the reality is that most of the mutations are not easily "druggable," and the discovery of these mutations has not yet significantly impacted patient outcomes. This is perhaps the most crucial challenge facing a translational cancer researcher like myself. My current research is a major step toward my long-term goal of making personalized medicine a reality for patients with acute myeloid leukemia (AML) and other hematologic malignancies.

    Since joining the Majeti lab, I have been targeting the ten-eleven translocation methylcytosine dioxygenase-2 (TET2) mutation, which is aberrant in leukemia at a high rate and has been studied using human-derived cells. TET2 is known to be involved in the clonal expansion of cells, and people with this mutation are more likely to suffer from hematologic malignancies. It is also known to be involved in the development of coronary artery disease, a gene that has attracted much attention in recent studies. In my field, it is an essential gene involved in the abnormal proliferation of hematopoietic stem cells. Focusing on this gene, I mapped TET2-dependent 5hmC, epigenetic and transcriptional programs matched to competitive advantage, myeloid skewing, and reduced erythroid output in TET2-deficient hematopoietic stem and progenitor cells (HSPC). Vitamin C and azacitidine restore the 5hmC landscape and phenotypes in TET2-mutant HSPCs. These findings offer a comprehensive resource for TET-dependent transcriptional regulation of human hematopoiesis and shed light on the potential mechanisms by which TET deficiency contributes to clonal hematopoiesis and malignancies. Of course, these findings would also be of value in understanding the biology of normal hematopoietic stem cells (HSCs) and various other TET2-related cancers.

    And from now on, I would like to use the single-cell transplantation techniques mastered in the Majeti lab to study the behavior of normal and aberrant human HSCs using various new methods, ultimately preventing the progression of AML.

    In my clinical experience, I have lost many AML patients. With the regret and sadness of losing these patients in my heart, I hope to one day contribute to developing treatments that will fundamentally change how the world treats leukemia.

  • Vaidehi Natu

    Vaidehi Natu

    Physical Sci Res Scientist

    Current Research and Scholarly InterestsI am a developmental neuroscientist. My research program aims to study how the human brain matures from infancy to adulthood, as it acquires new life skills and behaviors: What are the origins of neural and cellular mechanisms of brain development during infancy? How does the trajectory of cellular mechanisms unfold during development, as school-aged children acquire complex skills such as reading or face recognition? What are some of the parallels in brain development across primate species? What changes occur in the brain in developmental disorders such as autism, multiple sclerosis, and dyslexia.

    I use a multi-modal approach by combining different techniques to study the brain. I use neuroimaging methods including functional magnetic resonance imaging (fMRI), quantitative MRI (qMRI), and diffusion MRI (dMRI) as well as behavioral observations, histology, comparative methods across humans and macaques, and intracranial electroencephalography. This combination of complementary techniques provides a unified understanding of how the brain’s anatomy, function, and behavior co-develop to achieve complex human skills.

    Clinical Assistant Professor, Radiology - Rad/Nuclear Medicine

    BioI am originally from San Diego, California where I attended medical school and did a surgical internship at UCSD. While there, I was exposed to the field of Nuclear Medicine and became fascinated by molecular imaging and the burgeoning field of theragnostics. I chose the Nuclear Medicine residency program at Stanford because it is one of the premier molecular imaging programs in the world, where some of the best known physicians and scientists in the field are located. Situated in Silicon Valley and rooted in a culture of collaboration, Stanford reaps the benefits from being at the intersection of technology, innovation, engineering and science to produce ground breaking research that continually pushes the imagination and limits of Nuclear Medicine. I am honored to be able to pursue my clinical interests and further my career in this environment.

  • Quan Dong Nguyen, MD, MSc

    Quan Dong Nguyen, MD, MSc

    Professor of Ophthalmology and, by courtesy, of Pediatrics and of Medicine (Immunology & Rheumatology)

    Current Research and Scholarly InterestsWe have focused our research on the development of novel therapies and innovative assessment and diagnostic imaging technologies for retinal vascular and ocular inflammatory disorders, specifically diabetic retinopathy (DR), age-related macular degeneration (AMD) and uveitis. Building on our initial work describing the role of hypoxia and vascular endothelial growth factor (VEGF) in diabetic retinopathy (DR) and diabetic macular edema (DME), We have become interested in the biochemical mechanisms that would presumably lead to DME. During the past decade, our research has contributed to the body of evidences that defines the important role of anti-VEGF therapies in DME and AMD, as well as the role of the mTOR pathway and various interleukins in the pathogenesis of uveitis.

    We have launched a productive and well-funded clinical research program while at the same time providing clinical care to patients with uveitis and retinal vascular diseases and fulfilling significant teaching and administrative assignments. We have established a number of key collaborators both within and outside the institutions. In addition, we have also established Center in Baltimore and now in Silicon Valley, which has excelled in conducting proof-of concept, early-phase multi-center clinical trials and studies, exploring the clinical disease manifestations and the efficacy of various pharmacologic agents in retinal, uveitic, and ocular inflammatory disorders.

    Jennifer Ni

    Adjunct Clinical Assistant Professor, Pediatrics - Endocrinology and Diabetes

    BioI grew up mainly in the Bay Area of California, attending UC Berkeley for undergraduate (Go Bears!) with a major in Bioengineering. After a gap year working at a biotech start up, I traveled to the East Coast for medical school at the University of Pittsburgh, and then back to my birth state of Texas for residency at UT Southwestern. During my experiences in medical school and residency, I discovered that I enjoyed the logic of thinking through signaling pathways to understand the pathophysiology of endocrine disorders. In the future, I hope to combine my background in engineering with my passion for medicine to advance the field of endocrinology, especially in diabetes management. I am very excited to return to the Bay Area for fellowship in Pediatric Endocrinology. Outside of the hospital, I enjoy baking sweet treats, trying new restaurants, and running.
