abstractText | Follicular dendritic cells (FDCs) are important for the induction of protective T cell-dependent humoral responses, but their contribution to autoimmunity remains elusive. Here, gene-targeted interruption of FDC development was combined with the K/BxN mouse model of arthritis. We found that FDCs were essential for autoantibody production through two distinct but cooperative functions. In a T cell-independent fashion, FDCs loaded with autoantigen-containing immune complexes supported germinal center (GC) B cell development. Additionally, the integrity of FDC networks was required for the recruitment of arthritogenic follicular helper T cells, a process that drove T-B cell interactions and productive GC reactivity. Importantly, pharmacological interference in the maintenance of FDCs ameliorated disease development, suggesting the FDC as a potential target for dampening autoimmunity. |
