Hideki Ueno, M.D, Ph.D. is a Professor at Global Health and Emerging Pathogens Institute and Department of Microbiology. Dr. Ueno has more than 15 years of experience on immunology research with primary human cells. His research focuses on the studies on the adaptive immune system in humans, the major immunological protection mechanism in charge of generation and maintenance of antigen-specific immune response.

T Follicular Helper Cells in Human Autoimmunity
Tfh cells play a major pathogenic role in Systemic Lupus Erythematosus (SLE). However, the precise mechanism remains largely obscure. We are aiming at identifying the feature of pathogenic Tfh cells unique to SLE, and determining how the pathogenic Tfh cells contribute to altered B cell responses in patients with SLE.
Basic Science on Human T follicular helper cells
T follicular helper (Tfh) cells represent a CD4+ T cell subset specialized for providing help to B cells. Dysregulation of Tfh responses are associated with autoimmunity (when excessive) and with poor antibody response (when insufficient). My lab aims to identify the molecules and pathways controlling human Tfh responses.
Pathogenic CD4+ T cells in Human Neuroinflammatory Diseases
Depletion of B cells is effective to treat patients with neuromyelitis optica (NMO) and multiple sclerosis (MS), but the immune mechanism remains unclear. We are interested in how B cell depletion affects the antigen-specific CD4+ T cell repertoires in patients. Towards this goal, we are currently developing a new assay that permits the detection of antigen-specific T cells with superior sensitivity and specificity to currently available assays.
Immune Mechanisms Associated with Protective Ab Response for Influenza
While both vaccination and infection induce Tfh and antibody response, the magnitude and the quality of Tfh responses are radically different. Our previous studies show that seasonal influenza vaccination induces antibody response by activating a specific Tfh subset, called Tfh1 cells, together with influenza-specific memory B cells in humans. We aim to define the fundamental biological differences on memory Tfh cells generated by influenza infection and vaccination, and determine the key molecules and pathways associated with long-lived memory Tfh cells in humans.
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr.Ueno did not report having any of the following types of financial relationships with industry during 2019 and/or 2020: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
