Abstract
Rheumatoid arthritis is a chronic autoimmune pathology characterized by the proliferation and inflammation of the synovium. Boron neutron capture synovectomy (BNCS), a binary treatment modality that combines the preferential incorporation of boron carriers to target tissue and neutron irradiation, was proposed to treat the pathological synovium in arthritis. In a previous biodistribution study, we showed the incorporation of therapeutically useful boron concentrations to the pathological synovium in a model of antigen-induced arthritis (AIA) in rabbits, employing two boron compounds approved for their use in humans, i.e., decahydrodecaborate (GB-10) and boronophenylalanine (BPA). The aim of the present study was to perform low-dose BNCS studies at the RA-1 Nuclear Reactor in the same model. Neutron irradiation was performed post intra-articular administration of BPA or GB-10 to deliver 2.4 or 3.9 Gy, respectively, to synovium (BNCS-AIA). AIA and healthy animals (no AIA) were used as controls. The animals were followed clinically for 2 months. At that time, biochemical, magnetic resonance imaging (MRI) and histological studies were performed. BNCS-AIA animals did not show any toxic effects, swelling or pain on palpation. In BNCS-AIA, the post-treatment levels of TNF-α decreased in four of six rabbits and IFN-γ levels decreased in five of six rabbits. In all cases, MRI images of the knee joint in BNCS-AIA resembled those of no AIA, with no necrosis or periarticular effusion. Synovial membranes of BNCS-AIA were histologically similar to no AIA. BPA-BNCS and GB-10-BNCS, even at low doses, would be therapeutically useful for the local treatment of rheumatoid arthritis.

Abstract
OBJECTIVE Emerging evidence indicates that low-grade inflammation is part of the clinical picture of OA and that there is a need to identify soluble biomarkers of ongoing inflammation in the joint from a translational aspect. The aim of this study was to compare levels of pro-inflammatory biomarkers in SF, serum and/or EDTA plasma. METHODS SF and blood from rats subjected to Freund's complete adjuvant (FCA; n = 48) or monoiodoacetate (MIA; n = 88) monoarthritis and from control rats were collected over time. SF, EDTA plasma and serum were obtained from six individuals with OA of the knee and healthy controls. Levels of IL-6, KC/GRO, IL-8, monocyte chemoattractant protein 1 (MCP-1), macrophage inflammatory protein 3α (MIP-3α), IL-1β, TNF and l(+)-lactate were assessed either by immune assay or by a colorimetric method. RESULTS Elevated levels of biomarkers were shown in monoarthritic animals in SF compared with the control groups, although with considerably lower magnitude in the MIA groups, which also indicated a biphasic pattern. Levels of KC/GRO and MIP-3α in serum from the FCA model and IL-6 in the MIA model followed the pattern of SF. In serum samples from OA individuals, MIP-3α correlated significantly with levels in SF. CONCLUSION While we found increased levels of markers in joint fluid and blood, no single systemic biochemical biomarkers that were a common denominator between the animal models and the patient material could be identified. Our data indicate that it is critical to delineate the temporal profile of multiple local and systemic factors in order to pinpoint soluble biomarkers for OA.

Abstract
Recent research on the heat shock proteins (Hsps) in chronic inflammatory diseases indicates that Hsps may have disease-suppressive activities. Our aim was to characterize immune response directed to bacterial (DnaJ) and human Hsp40s in patients with rheumatoid arthritis (RA). We found elevated levels of anti-DnaJ, anti-Hdj2, and anti-Hdj3 (but not ant-Hdj1) serum antibodies in the RA patients (P < or = 0.001) compared to healthy controls. In peripheral blood mononuclear cells (PBMCs) culture, all tested Hsp40 proteins significantly inhibited the divisions of CD4+ and CD8+ T cells of the RA patients but not those of the controls. Both DnaJ and Hdj2 stimulated secretion of the main anti-inflammatory cytokine IL-10 by PBMCs of the RA patients (P < 0.05), and of IL-6 by PBMCs of the RA (P < 0.001) and control (P < 0.01) groups. DnaJ reduced TNFalpha secretion (P < 0.05) by both groups of PBMCs. Our results show for the first time that the RA patients have an increased humoral response to human Hsp40 proteins Hdj2 and Hdj3. This is also the first description of immunomodulatory effect of human Hsp40s on T cells and cytokine secretion in RA, suggesting that Hsp40s act as natural anti-inflammatory agents in RA.
