Research focus
My research focuses on the role of tumor-draining lymph nodes (TDLNs) in cancer. TDLNs are important sites for induction of an effective anti-tumor immune response. Not only is this the site where T-cells are primed, but TDLNs are also critically involved in anti-PD-1/PD-L1 treatment efficacy in preclinical tumor models, activating and expanding TCF1+ progenitor CD8+ T cells that give rise to effector T cells at the tumor microenvironment. Besides its role in immune activation, immune suppression in TDLNs might prevent a durable and effective systemic anti-tumor immune response instead. Understanding the biology of T cells including progenitor T cells in TDLNs, their relationship to tumor-infiltrating T cells (TILs) and the cellular interactions in both TDLN and tumor microenvironment (TME) that shape their identity is key.
Furthermore, we focus on understanding the relationship between type 2 immunity and cancer. Evidence on the role of type 2 inflammation in primary tumor formation is controversial, the underlying molecular and cellular mechanisms are not completely understood, and the possible dichotomous functions of stroma and cancer-derived pro-Th2 alarmins and subsequent type 2 effector pathways in tumor immunity in various cancers have yet to be determined. We set out to unravel the complex interplay between innate and adaptive immune cells and the stroma and how this affects the TME and drives tumor formation and shapes the immune response in the TDLN.
