Memory T Cell Migration
Immunological memory is a key feature of adaptive immunity. It provides the organism with long-lived and robust protection against infection. In organ transplantation, memory T cells pose a significant threat by causing allograft rejection that is generally resistant to immunosuppressive therapy. Therefore, a more thorough understanding of memory T cell biology is needed to improve the survival...
متن کاملAILIM/ICOS signaling induces T-cell migration/polarization of memory/effector T-cells.
AILIM/ICOS has critical roles in the regulation of T-cell differentiation and effector T-cell function in various immune responses. The counter-ligand for AILIM/ICOS, B7h, is widely expressed in not only lymphoid tissue and antigen-presenting cells, but also in fibroblast and endothelial cells in various organs. Here, we demonstrate that activated human T-cells migrate beneath TNF-alpha-treated...
متن کاملT-cell migration into allografts
The ability of T and B lymphocytes to migrate into skin allografts undergoing rejection was studied in mice. Spleen cells from CBA/J mice sensitized to transplantation antigens of A/J or C57BL/6 mice were separated on immunabsorbent columns into purified populations of T and B cells, labeled in vitro with 3H-uridine and injected intravenously into CBA/J mice with 7-day old skin iso and allograf...
متن کاملDynamic T cell migration program provides resident memory within intestinal epithelium
Migration to intestinal mucosa putatively depends on local activation because gastrointestinal lymphoid tissue induces expression of intestinal homing molecules, whereas skin-draining lymph nodes do not. This paradigm is difficult to reconcile with reports of intestinal T cell responses after alternative routes of immunization. We reconcile this discrepancy by demonstrating that activation with...
متن کاملDynamics of blood-borne CD8 memory T cell migration in vivo.
Memory T cells are distributed throughout the body following infection, but the migratory dynamics of the memory pool in vivo is unknown. The ability of circulating microbe-specific memory T cells to populate lymphoid and nonlymphoid tissues was examined using adoptive transfer and parabiosis systems. While migration of memory CD8 T cells to lymph nodes and peritoneal cavity required G(i)-coupl...
