Postdoctoral Fellow Position, Bacchetta Laboratory, Stanford University


The Bacchetta Laboratory has an opening for a highly motivated, dedicated, passionate and curiosity-driven postdoctoral fellow with background knowledge in immunology and a strong interest in translational research, gene and cell therapy as well as basic human immunology.  The laboratory has developed a novel gene-therapy based Treg cell product – CD4LVFOXP3. The CD4LVFOXP3 cells are made by conversion of conventional T cells to Treg like cells by lentiviral mediated expression of FOXP3. This cell product will be tested at the Stanford Pediatrics Hospital in a Phase I proof-of-principle First-Time-in-Humans clinical trial for a rare genetic immune regulatory disorder, called IPEX Syndrome, a prototype of autoimmune genetic disease (Passerini et al., Sci Transl Med 2013. and Sato Y. Clinical and Translational Immunology, 2020). This clinical trial represents first in human clinical trial with genetically engineered Treg-like cells.

The postdoctoral candidate’s primary focus will be: 

(1)   Explore the use of this lentiviral-based CD4+ Treg-like cell product for different and more common autoimmune indications, such as Inflammatory Bowel Disease (IBD). We aim to study the still ill-defined role of Treg cells in pediatric IBD patients by examining the immune- gut mucosa interactions in 2D and 3D gut organoids using a broad range of cutting-edge molecular biology techniques, and in collaboration with world leaders in regenerative medicine at the Stem Cell Biology and Regenerative Medicine Institute in which the Bacchetta Lab is located. Organoids obtained from IBD patients will serve as a novel preclinical model to understand the safety and efficacy of the CD4LVFOXP3 Treg-like cells, including their ability to regulate adaptive immune responses in the gut and their role in gut mucosa healing and regeneration.

(2)   Participate in immune monitoring studies of IPEX patients treated with CD4LVFOXP3 Treg-like cells, assessing their in vivo survival, phenotypic and functional stability, and studying how they affect the patient immune system. These studies will generate unprecedented information on the role of regulatory T cells in shaping immune cell phenotype and on pharmacokinetics and pharmadynamics of Treg cells in vivo.

This position is an excellent opportunity for a candidate who is interested in both translational research and state-of-the-art basic human immunology.  This work will provide a unique experience that will be particularly valuable for trainees considering long-term careers in biomedical research and translational medicine. During the postdoctoral training the candidate will be encouraged to further develop his/her project beyond the original scope outlined, as well as develop skills in writing grants and designing projects and actively participate in internal and external international meetings. The candidate will join the Division of Pediatric Hematology, Oncology and Stem Cell Transplantation and Regenerative Medicine at Stanford University School of Medicine and work in close collaboration with the other members of the Bacchetta/Roncarolo Lab, the Immunology Division, the Pediatric Stem Cell Transplantation Unit and the Center for Definitive and Curative Medicine (CDCM).
