TCR-Specific Regulation and Protection Vaccination with BV8S2 Protein Amplifies

Estrogen potentiates treatment with T-cell receptor protein of female mice with experimental encephalomyelitis.

Transgenic mice expressing the BV8S2 chain, which is specific for the myelin basic protein determinant Ac1-11, possess a naturally induced set of regulatory T cells directed against BV8S2. Further activation of anti-BV8S2 T cells in male mice with recombinant BV8S2 protein can inhibit IFN-gamma release by Ac1-11-specific T cells through a cytokine-driven mechanism and prevent induction of exper...

Reduced chemokine and chemokine receptor expression in spinal cords of TCR BV8S2 transgenic mice protected against experimental autoimmune encephalomyelitis with BV8S2 protein.

The perivascular transmigration and accumulation of macrophages and T lymphocytes in the CNS of mice with experimental autoimmune encephalomyelitis (EAE) may be partly regulated by low m.w. chemotactic cytokines. Using the RNase protection assay and ELISA, we quantified expression of chemokines and chemokine receptors in the spinal cord (SC), brain, and lymph nodes of BV8S2 transgenic mice that...

A TCR affinity threshold regulates memory CD4 T cell differentiation following vaccination.

Diverse Ag-specific memory TCR repertoires are essential for protection against pathogens. Subunit vaccines that combine peptide or protein Ags with TLR agonists are very potent at inducing T cell immune responses, but their capacity to elicit stable and diverse memory CD4 T cell repertoires has not been evaluated. In this study, we examined the evolution of a complex Ag-specific population dur...

Encephalomyelitis with BV8S2 Protein Experimental Autoimmune BV8S2 Transgenic Mice Protected Against Receptor Expression in Spinal Cords of TCR Reduced Chemokine and Chemokine

The complementarity determining region 2 of BV8S2 (V beta 8.2) contributes to antigen recognition by rat invariant NKT cell TCR.

Invariant NKT cells (iNKT cells) are characterized by a semi-invariant TCR comprising an invariant alpha-chain paired with beta-chains with limited BV gene usage which are specific for complexes of CD1d and glycolipid Ags like alpha-galactosylceramide (alpha-GalCer). iNKT cells can be visualized with alpha-GalCer-loaded CD1d tetramers, and the binding of mouse CD1d tetramers to mouse as well as...
