The role of T cell receptor dimerization for T cell antagonism and T cell specificity

Molecular Immunology, 1998
T cell responses are highly specific and T cell receptors (TCRs) can recognise subtle differences in major histocompatibility complex (MHC)-peptide complexes. While nominal peptide antigens usually act as full agonists that trigger the whole spectrum of T cell responses, some peptides exhibiting mutations at the TCR-MHC/peptide contact site stimulate ...

Splenic CD8(+) T cells secrete TGF-beta 1 to exert suppression in mice with anterior chamber-associated immune deviation [PDF]

, 2009
Background CD8(+) regulatory T cells (Treg) have been considered to be involved in a model of ocular-induced tolerance, known as anterior chamber-associated immune deviation (ACAID).

The Effect of Moringa oleifera Leaves and VipAlbumin® on The Immune System of Diabetes Mellitus Balb/C Mice Model

Journal of Experimental Life Science, 2019
Diabetes Mellitus is known as a disease grown worldwide rapidly prevalent day by day. This disease caused by a chronic hyperglycemic condition and also glucose intolerance resulting from defects in insulin secretion, insulin action, or both.

Multi-faced roles of reactive oxygen species in anti-tumor T cell immune responses and combination immunotherapy

Exploration of Medicine, 2022
T cells play a central role in anti-tumor immunity, and reactive oxygen species (ROS) lie at the crossroad on the anti-tumor T cell responses. To activate efficient T cell immunity, a moderate level of ROS is needed, however, excessive ROS would cause ...

Selective inhibition of T suppressor-cell function by a monosaccharide [PDF]

, 1981
Interactions between regulatory T lymphocytes and other cells are assumed to occur at the level of the cell surface. T cells which suppress the generation of specifically effector cells have been described as having antigenic, idiotypic, allotypic and I ...

T cells in ITP: Focus on T follicular helper cells and cytotoxic T cells. [PDF]

Br J Haematol
Summary Immune thrombocytopenia (ITP) is an autoimmune disease where premature destruction of platelets as well as inhibition of platelet production leads to thrombocytopenia and associated bleeding. It has long been considered a disease primarily caused by B cells, but the role of T lymphocytes in its pathogenesis is now better ...

γδ T cells affect IL-4 production and B-cell tolerance [PDF]

, 2014
γδ T cells can influence specific antibody responses. Here, we report that mice deficient in individual γδ T-cell subsets have altered levels of serum antibodies, including all major subclasses, sometimes regardless of the presence of αβ T cells.

T Cell Hybrids with T Cell Functions

, 1979
Different T cell functions, e.g. help, suppression and cytotoxicity are associated with different T cell subsets, bearing distinctive differentiation markers. Thus effector T cells mediating help are Ly 1+2−3− and may bear Ia determinants, those mediating suppression are Ly 1−2+3+, IJ+, and cytotoxic cells are Ly 1−2+3+ and do not bear Ia determinants (

Protocol for engineering binding domains to recognize ligand-bound receptors by using yeast surface display

STAR Protocols
Summary: Yeast surface display is a versatile protein engineering technology, enabling precise control of the applied selection pressure. We present a yeast-surface-display-based protocol for the enrichment of binders specifically recognizing ligand ...

Responses of T cells to ligands for the T-cell receptor

Seminars in Immunology, 1996
We have learned a great deal about the recognition of MHC class II:peptide complexes by concentrating on the responses of a single cloned T-cell line, called D10. From these results, we argue for a single orientation of all CD4 T-cell receptors to their MHC ligands, based on the uneven top surface of MHC molecules, the repeated isolation of cells with ...
