B and T lymphocyte attenuator suppresses IL-21 production from follicular Th cells and subsequent humoral immune responses.
We recently showed that mice lacking B and T lymphocyte attenuator (BTLA), a third inhibitory coreceptor expressed on B cells and T cells, exhibit an increased Ag-specific IgG response and gradually develop hyper-gamma-globulinemia and autoantibody production. Recent studies revealed that follicular Th (Tfh) cells, which are non-Th1, non-Th2 effector T cells that express CXCR5 and provide help ...
متن کاملIL-21 and T follicular helper cells.
Upon encounter with antigen, CD4(+) T cells differentiate into effector T(h) subsets with distinctive functions that are related to their unique cytokine profiles and anatomical locations. One of the most important T(h) functions is to provide signals to developing B cells that induce specific and appropriate antibody responses. The major CD4(+) T cell subset that helps B cells is the T follicu...
متن کاملB and T lymphocyte attenuator expression on CD4+ T-cells associates with sepsis and subsequent infections in ICU patients
INTRODUCTION Sepsis is a deadly inflammatory condition that often leads to an immune suppressed state; however, the events leading to this state remain poorly understood. B and T lymphocyte attenuator (BTLA) is an immune-regulatory receptor shown to effectively inhibit CD4+ T-cell function. Therefore, our objectives were to determine: 1) if lymphocyte BTLA expression was altered in critically i...
متن کاملSkin DC Induce Follicular Helper T Cells and Protective Humoral Immune Responses
Background—The contribution of individual subsets of dendritic cells (DC) to the generation of adaptive immunity is central to understanding immune homeostasis and protective immune responses. Objective—We sought to define functions for steady-state skin DC. Methods—Herein we present an approach in which we restrict antigen presentation to individual DC subsets in the skin and monitor the effec...
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 ...
