Biography

Dr. Zusen Fan, Professor, Mentor for Ph.D candidates. Deputy Director of the Teaching and Research Department for Infection and Immunity at CAS University, CAS Center for Excellence in Biomacromolecules, Institute of Biophysics, CAS. Dr. Fan obtained Ph.D degree in the Medical School of Shanghai Jiaotong University in 1998, and then got postdoctoral training in Harvard Medical School, and promoted Instructor of Harvard University in 2003. Eventually he was recruited to the Institute of Biophysics of CAS as professor in 2004. In 2005, he got the National Outstanding Youth Grant from NSFC. In 2006, he was granted as the National Talents of “Hundred-Thousand-Tenthousand Program”. In 2010, he was awarded as the State Council Expert for Special Allowance. In 2014, he was granted with Tan Jiazhen Life Sciences Innovation Award. In 2014, he was selected as Outstanding Professor of the CAS University. In 2015, he was recruited to the CAS Center for Excellence in Biomacromolecules. In 2016 and 2018, he was awarded to CAS Outstanding Graduate Tutor Award. In 2018, he was awarded as the First prize of Beijing Science and technology progress award. In 2019, he was granted as a principal scientist of Innovation Group Grant of NSFC. In 2020, he was granted as a principal scientist of the National Key R&D Program of China. Fan Lab focuses on these three major research fields: 1) New immune cell subsets and immune mechanisms against infections and tumors; 2) Noncoding RNAs and immune regulations; 3) Mechanisms of reprogramming and self-renewal of cancer stem cells as well as tumor immunotherapy.

Research Interests

1. Identification of new innate immune cell subsets, definition of their effector functions against infections and their mechanisms of trans-differentiation in intestinal diseases

Innate lymphoid cells (ILCs) are located in mucosal surfaces to potentiate immune responses, sustain mucosal integrity and promote lymphoid organogenesis. Group 1 (ILC1) cells are characterized by their capacity to secrete interferon γ (IFN-γ) responding to interleukin 12 (IL-12), IL-15 and IL-18. Group 2 (ILC2) cells generate type 2 T helper (Th2) cell cytokines such as IL-5, IL-9 and IL-13 in response to IL-25 and IL-33 stimulation. Group 3 (ILC3) cells produce IFN-γ, IL-17 and IL-22 upon stimulation with IL-1 and IL-23. However, it is still unclear how ILCs are regulated and how ILCs are transdifferentiated in physiological and pathological settings. We want to identify new subsets of innate immune cells and define their effector functions against infections. We will reveal whether and how ILCs undergo transdifferentiation in physiological and pathological settings and elucidate their underlying mechanisms of transdifferentiation.

2. Discovery of new ncRNAs in innate immune cell subsets and definition of their regulatory roles in immune responses

Long noncoding RNAs (lncRNAs) are defined as transcripts longer than 200 nucleotides (nt) with limited coding potential. LncRNAs function in a wide range of biological processes and can regulate gene expression in cis or in trans by diverse mechanisms. LncRNA-mediated biology has been implicated in many cellular processes. However, how lncRNAs regulate immune cell development and immune responses still remains elusive. We will identify new lncRNAs in ILC lineages and reveal their roles in their development and effector functions in immune responses.

3. Elucidation of reprogramming and self-renewal of cancer stem cells and strategies for tumor immunology

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, ranking the third leading cause of cancer-related deaths. The high rate of recurrence and heterogeneity are the 2 major features of HCC. The cancer stem cell model (CSC model) proposes that only a rare subset of cancer cells within tumor bulk display the capacity to self-renew, differentiate, and generate a new tumor. These CSCs are responsible for sustaining tumor growth and are resistant to conventional treatments, accounting for a hierarchical organization of heterogeneous cancer cells and a high rate of cancerous recurrence. However, the hepatic CSC biology remains largely unknown. We already identified a bunch of important genes and lncRNAs that are implicated in the regulation of liver CSCs. We next sought to elucidate their roles of our identified genes and lncRNA in the self-renewal maintenance of liver CSCs. Finally, we will develop new strategies to block the self-renewal capacity of liver CSCs, leading to new therapy for cancer patients.
