IFNg-producing Tfh cells control the differentiation of lung resident memory B cells


ABSTRACT: T follicular helper (Tfh) cells are a specific subset of CD4 T cells that localize in the B cell follicle and are essential for the Germinal Center (GC) response. Under polarizing environments, Tfh cells produce IFN-g. Beyond promoting class switching, the role played by IFN-g-producing Tfh cells remains largely unexplored. Using an influenza infection model, we show here that interactions with IFN-γ producing Tfh cells during the peak of the response skew the GC B cell response towards the memory differentiation pathway. Consequently, lung-memory B cells fail to differentiate without IFN-γ producing Tfh cells. Collectively, our results support a model in which temporary changes in cytokine production by Tfh cells dynamically control the outcome of the GC response.
