    Biosketch

    Dr. Feng Hefeng (also known as Feng He) is currently a senior scientist focusing on immune ageing and systems immunology in the Department of Infection and Immunity at the Luxembourg Institute of Health (LIH). From Mar. 2015 to Mar. 2020, Feng had led an independent junior research group in the Department of Infection and Immunity at the LIH. From Mar 2020-Dec 2021, Feng had worked as a visiting scientist at Institute of Clinical Microbiology, University Hospital Essen.

    Feng accomplished his PhD (cumulative thesis) in experimental systems biology at the Technical University of Braunschweig, Germany and the Helmholtz Centre for Infection Research (HZI) supervised by Prof. An-Ping Zeng. Feng then had received his early career training in Prof. Klaus Schughart's group at HZI for two years. Afterwards, during his five-year term as a research associate at the University of Luxembourg in Prof. Rudi Balling’s lab and as a visiting researcher at the University of Cambridge and the Institute for Systems Biology, Seattle, Feng has initiated and developed his systems-biology-guided experimental immunology strategy, i.e., starting from the large-scale hypothesis-free unbiased screening followed by experimental validation of novel functions of key candidates and gene networks for various types of immune cells, especially T cells, from dynamic/time-series ‘Omics’ datasets.

    Being the principal investigator (PI), Feng has been awarded several competitive grants through different external funding sources, either from Luxembourg National Research Fund (FNR) CORE (1X as PI and 1X as CoPI), individual AFR (2X), bilateral AFR (1X) and PRIDE DTU programmes (3X) or from the European Commission Horizon Europe programmes (as the partner). Feng has also been supported twice by the Luxembourg Personalized Medicine Consortium (PMC) pump prime funds.

    Research interests

    Theme 1: Immune Ageing/Immunoageing

    The remarkable increase in life expectancy has been estimated to result in a global rise of elderly people worldwide. This will inevitably lead to an increase in the number of people suffering from complex non-communicable diseases and infectious diseases for which age is the major risk factor. The high prevalence of complex diseases among the elderly is at least partially caused by a decline in the protective functions of both the innate and the adaptive immune system over time, a process known as immunoaging. Feng and team seek to understand the underlying molecular and cellular mechanisms through which the immune functions decline. They discover that one key familial Parkinson’s disease (PD) gene (PARK7, encoding DJ-1) critically regulates the immunoageing process, not only in conventional CD4 and CD8 T cells (Zeng et al., EMBO Reports), but also in regulatory T cells using both rodent animal models and patients with DJ-1 deficiency (Danileviciute, et al., Nature Metabolism). Mechanistically, they reveal that DJ-1 regulates T cell homeostasis via modulating the activity of pyruvate dehydrogenase (PDH), the key gatekeeper enzyme of the tricarboxylic acid (TCA) cycle. Although the PDH enzyme activity is known to be tightly regulated by several PDH kinases and phosphatases, their findings add a new dimension to the regulation of the PDH complex and enable a better understanding of the PDH supercomplex system. Their discovery paves the way to make T cells “younger” when the people become older, which might have critical implementations in various ageing-associated diseases.

    Beyond investigating rare genetic causes of PD cases, Feng and team further asked whether the observed DJ-1-deficiency mediated immunological dysregulation could be also applicable to a broader spectrum of PD, i.e., idiopathic PD (iPD). In another original work led by Feng (Capelle et al., 2023, Nature Communications), they found an enhanced cytotoxic immune milieu in early-to-mid stage iPD, with a much higher frequency of terminally-differentiated effector CD8 T (TEMRA) and enhanced cytotoxic pathways in CD8 TEMRA of PD patients. The frequency of CD8 TEMRA was negatively correlated with disease duration, suggesting a contribution to iPD pathogenesis.  As a natural extension, Feng and team are currently investigating the molecular mechanisms promoting or suppressing the differentiation of CD8 TEMRA and their implementation in PD pathogenesis via several external competitive funds.

    Theme 2: Systems Immunology

    In parallel to their efforts in basic immunology, based on their long-term interest in holistic research, Feng and team have also established a deep immunophenotyping systems-immunology pipeline at a single-cell level and successfully applied it to several complex or infectious diseases, such as COVID-19 (Capelle et al., Cell Reports Medicine). Those unbiased approaches have led to several unexpected discoveries.
