Abstract
OBJECTIVES Successful early intervention in rheumatoid arthritis (RA) with the aim of resetting immunological tolerance requires a clearer understanding of how specificity, cellular kinetics and spatial behaviour shape the evolution of articular T cell responses. We aimed to define initial seeding of articular CD4+ T cell responses in early experimental arthritis, evaluating their dynamic behaviour and interactions with dendritic cells (DCs) in the inflamed articular environment. METHODS Antigen-induced arthritis was used to model articular inflammation. Flow cytometry and PCR of T cell receptor (TCR) diversity genes allowed phenotypic analysis of infiltrating T cells. The dynamic interactions of T cells with joint residing DCs were visualised using intravital multiphoton microscopy. RESULTS Initial recruitment of antigen-specific T cells into the joint was paralleled by accumulation of CD4+ T cells with diverse antigen-receptor expression and ability to produce tumour necrosis factor alpha (TNFα) and interferon gamma (IFNγ) on mitogenic restimulation. A proportion of this infiltrate demonstrated slower motility speeds and engaged for longer periods with articular DCs in vivo. Abatacept treatment did not disrupt these interactions but did reduce T cell expression of inducible costimulatory (ICOS) molecule. We also demonstrated that non-specific CD4+ T cells could be recruited during these early articular events. CONCLUSIONS We demonstrate that CD4+ T cells engage with articular DCs supporting antigen specific T cell reactivation. This cellular dialogue can be targeted therapeutically to reduce local T cell activation.

Abstract
Considering the role of T-lymphocytes in rheumatoid arthritis (RA) and a possible involvement of the TCR in the pathology of this disease we analyzed allelic and genotypic frequencies of variants of two TCRBV gene segments (TCRBV3S1 and TCRBV18) in RA. A total of 95 caucasoid South Brazilian RA patients were genotyped for both TCRBV gene segment variants by restriction fragment length polymorphism preceded by PCR (PCR-RFLP) and the obtained frequencies were compared to those from healthy individuals. Allelic frequencies for the TCRBV3S1 gene segment were, respectively, for RA patients and controls, 0.447 and 0.545 (allele 1) and 0.553 and 0.455 (allele 2). Allelic frequencies for the TCRBV18 gene segment were, respectively, for RA patients and controls, 0.824 and 0.806 (allele 1) and 0.176 and 0.194 (allele 2). Neither allelic frequencies nor genotypic frequencies differ among RA and healthy individuals, suggesting that there is not a direct association among the TCRBV allelic variants studied and the development of RA and thus excluding the possibility of use of these gene segment polymorphisms as RA susceptibility markers.

Abstract
Abstract
The role of T cells in the pathogenesis of rheumatoid arthritis (RA), especially in the perpetuation of advanced disease, remains unclear. Previous studies have focused on the TCR repertoire of synovial T cells in an attempt to determine whether the pattern of expression is characteristic of Ag-stimulated populations. However, the results of past studies have been conflicting. In the present work, we have undertaken an extensive analysis of the TCRs expressed by CD4+ T cells freshly isolated from synovial fluid of different joints and blood in three patients with established RA. Despite marked heterogeneity of synovial TCR expression, the results showed that 20 to 30% of the TCR β-chain gene (TCRB) sequences found in one joint were also expressed in a second joint, but not in peripheral blood T cells of the same individual. Analysis of expressed TCRB complementarity-determining region 3 sequences showed the presence of multiple expanded clonal populations that were not predicted by quantitation of β-chain variable region (Vβ) expression by immunofluorescence staining. These studies also demonstrated sets of related, but different, complementarity-determining region 3 nucleotide sequences that encoded identical or highly homologous β-chain amino acid sequences. Analysis of matching T cell clones derived from the joint by limiting dilution culture confirmed coexpression of highly homologous TCR α-chain gene (TCRA) and TCRB sequences. Together, these studies suggest that a significant proportion of synovial CD4+ T cells has been selected and expanded by conventional Ag(s) in this disease.
