Abstract:
Isolated regulatory B cells are disclosed, and compositions including these isolated regulatory B cells. The isolated regulatory B cells are mammalian and express T cell immunoglobulin mucin-1 (TIM-1). In some embodiments the regulatory B cells produce IL-10. Methods for treating a subject with an immune-mediated disorder are disclosed. These methods include administering to the subject a therapeutically effective amount of a composition including regulatory B cells, thereby treating the immune mediated disorder in the subject. Methods are also disclosed for treating a subject with an immune-mediated disorder, wherein the methods include administering to the subject a therapeutically effective amount of an antibody that specifically binds TIM-1, wherein the antibody is activates TIM-1CD19 B cells. Methods are also disclosed for assessing the immune status of a subject.
