PhD Studentship: Spatiotemporal Dynamics of Antigen-Specific T and B Cells in the Developing and Malignant CNS

Supervisors: Professor Richard Gilbertson and Dr Elizabeth Cooper

Department: Cancer Research UK Cambridge Institute

Course start date: 1st October 2026

Prof Richard Gilbertson and Dr Elizabeth Cooper wish to recruit a student to work on the project entitled: Spatiotemporal Dynamics of Antigen-Specific T and B Cells in the Developing and Malignant CNS.

The central nervous system (CNS) represents a uniquely regulated immune environment that changes across the lifespan. While adult immunity can mount robust responses to CNS antigens during inflammation, immune responses in the developing brain remain tightly controlled and poorly understood.

Our preliminary data indicate that in childhood brain tumours, antigen-specific T and B cell responses at the CNS borders are functionally impaired. We hypothesise that dysfunction of the meningeal lymphatic system leads to persistent antigen exposure and altered adaptive immune priming.

To address this, we have developed two novel engineered neoantigen models that enable precise dissection of antigen-specific immune responses in the CNS. These tools allow us to track the spatial and temporal dynamics of T and B cell interactions during brain development and disease.

This PhD project will uncover fundamental mechanisms of antigen-specific immunity in the developing CNS and establish broadly applicable models for studying immune responses across pediatric neurological disorders.
