T-cell receptor (TCR) usage in Lewis rat experimental autoimmune encephalomyelitis: TCR beta-chain-variable-region V beta 8.2-positive T cells are not essential for induction and course of disease.

Predominant usage of V beta 8.2 gene segments, encoding a T-cell receptor (TCR) beta chain variable region, has been reported for pathogenic Lewis rat T cells reactive to myelin basic protein (MBP). However, up to 75% of the alpha/beta T cells in a panel of MBP-specific T-cell lines did not display TCR V beta 8.2, V beta 8.5, V beta 10, or V beta 16 elements. To further investigate TCR usage, we sorted the T-cell lines for V beta 8.2- and V beta 10-positive T cells or depleted the lines of cells with these TCRs. V beta 8.2-positive T cells and one of the depleted T-cell lines strongly reacted against the MBP peptide MBP-(68-88). The depleted T-cell line caused marked experimental autoimmune encephalomyelitis (EAE) even in Lewis rats in which endogenous V beta 8.2-positive T cells had been eliminated by neonatal treatment with anti-V beta 8.2 monoclonal antibodies. T-cell hybridomas generated from this line predominantly used V beta 3 TCR genes coexpressed with TCR V alpha 2 transcripts, which were also used by V beta 8.2-positive T cells. Furthermore, V beta 10-positive T cells reactive to MBP-(44-67) were encephalitogenic when injected immediately after positive selection. After induction of EAE by sorted V beta 8.2- or V beta 10-positive T-cell lines, immunocytochemical analysis of the spinal cord tissue showed a predominance of the injected TCR or of nontypable alpha/beta T cells after injection of the depleted line. Our results demonstrate heterogeneity of TCR beta-chain usage even for a single autoantigen in an inbred strain. Moreover, V beta 8.2-positive T cells are not essential for the induction and progression of adoptive-transfer EAE.

Greece and the European Agenda: EU Enlargement and European Monetary Union. Program for the Study of Germany & Europe Working Paper 8.2

In the decade to come, the European Union will embark on two new projects, each destined to transform it in fundamental ways: (i) Eastern enlargement, and (ii) economic and monetary union. Neither of these projects will affect all members equally or in the same way. But Greece will, for two reasons, be affected in a manner qualitatively different to all other member states. First, Greece is the only country physically affected by the Luxembourg Summit's decision to begin accession negotiations with some, but not all, Central and Eastern European applicant countries: as a result of this decision, she will continue, for at least another eight to ten years, to be the only member country not to share a common border with another member state, with all the consequent implications in economic and geostrategic tenns. Second, when the European Council meets in early May to select those member states that are deemed to have met the convergence criteria, it will find that Greece is the only member state falling short of those criteria. This development may create additional difficulties for her economy during the transitional period of derogation. It will also pose new risks to Greece, insofar as she will be absent during the initial-and crucial-years of establishing a common monetary policy.
