Lane1 1 Medical Research Council (MRC) Centre for Immune Regulation, Institute for Biomedical Research, Birmingham Medical School, Birmingham, United Kingdom Lymphocytes from lymphotoxin (LT) –deficient mice, which lack segregation of their B- and T-cell areas, acquire normal organization following adoptive transfer into RAG-deficient recipients, identifying a non-B non-T cell in the segregation process. Here we show that a CD4+CD3– accessory cell is tightly associated with discrete VCAM-1–expressing stromal cells in B- and T-cell areas of the mouse spleen. CD4+CD3– cells express high levels of LT, LTß, and tumor necrosis factor (TNF) , which are the ligands for the LTß receptor and TNFR1 expressed by stromal cells. The expression of these ligands is functional, as transferring CD4+CD3– cells derived from either embryonic or adult tissues into LT-deficient mice organizes B/T segregation and up-regulates CCL21 protein expression in areas where T cells are segregated from B cells. We propose that the function of CD4+CD3– cells is to form a link between primed CD4 T cells and the underlying stromal elements, creating distinct microenvironments in which they enable effector responses.
