| abstractText | Immature autoreactive B cells are present in all healthy individuals, but it is unclear which signals are required for their maturation into antibody-producing cells. Inducible depletion of gammadelta T cells show that direct interaction between gammadelta T cells and immature B cells in the spleen support an "innate" transition to mature B cells with a broad range of antigen specificities. IL-4 production of gammadelta T cells and cell-to-cell contact via CD30L support B cell maturation and induce genes of the unfolded protein response and mTORC1 signaling. Eight days after in vivo depletion of gammadelta T cells, increased numbers of B cells are already stuck in the transitional phase and express increased levels of IgD and CD21. Absence of gammadelta T cells leads also to reduced levels of serum anti-nuclear autoantibodies, making gammadelta T cells an attractive target to treat autoimmunity. |
