Cutting edge: B and T lymphocyte attenuator and programmed death receptor-1 inhibitory receptors are required for termination of acute allergic airway inflammation.
T cell activation is regulated by coordinate interaction of the T cell Ag receptor and costimulatory signals. Although there is considerable insight into processes that regulate the initiation of inflammation, less is known about the signals that terminate immune responses. We have examined the role of the inhibitory receptors programmed death receptor-1 and B and T lymphocyte attenuator in the...
متن کاملCutting edge: A critical role of B and T lymphocyte attenuator in peripheral T cell tolerance induction.
T cell activation and tolerance are delicately regulated by costimulatory molecules. Although B and T lymphocyte attenuator (BTLA) has been shown as a negative regulator for T cell activation, its role in peripheral T cell tolerance induction in vivo has not been addressed. In this study, we generated a novel strain of BTLA-deficient mice and used three different models to characterize the func...
متن کاملCutting edge: programmed death-1 defines CD8+CD122+ T cells as regulatory versus memory T cells.
Recent convincing data have shown that naturally occurring CD8(+)CD122(+) T cells are also regulatory T cells. Paradoxically, CD8(+)CD122(+) T cells have been well described as memory T cells. Given their critical role in tolerance versus long-term immunity, it is important to reconcile this profound dichotomy. In this study, we reported that CD8(+)CD122(+) T cells contain both programmed death...
متن کاملB and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...
متن کاملCutting edge: Programmed death-1/programmed death ligand 1 interaction regulates the induction and maintenance of invariant NKT cell anergy.
Invariant NKT (iNKT) cells are a distinct subset of T lymphocytes that recognize glycolipid Ags. Upon TCR stimulation, iNKT cells promptly secrete a wide range of cytokines and therefore have been investigated as a target for immunotherapy. However, after primary activation, iNKT cells become hyporesponsive toward their ligand (anergy). The further mechanism behind iNKT cell anergy is poorly un...
