    "description": "Background We investigated the role of inhibitory receptors (IRs) and especially lymphocyte activation gene-3 (LAG-3) in the pathogenesis of oligoarticular juvenile idiopathic arthritis (o-JIA). Methods Paired samples of synovial fluid (SF) and plasma and peripheral blood (PBMCs) and synovial fluid mononuclear cells (SFMCs) were collected from o-JIA patients along with their clinical data (n = 24). Plasma from healthy controls (n = 14) and paired SF and plasma samples from five non-arthritic juvenile orthopedic patients (n = 5) served as controls. Spontaneously differentiated fibroblast-like synoviocytes (FLSs) from SFMCs were co-cultured with autologous PBMCs/SFMCs and used as ex vivo disease model. Soluble levels and cellular expressions of IRs together with their functional properties in the ex vivo model were analyzed. Results In patients with o-JIA, soluble levels of LAG-3 and expression of LAG-3 and T cell immunoglobulin mucin03 (TIM-3) on CD3(+)CD4(+)CD45RO(+) T cells were increased, especially in SF. Major histocompatibility complex (MHC) class II expression was induced on FLSs when these were co-cultured with autologous PBMCs/SFMCs, together with an increased monocyte chemoattractant protein-1 (MCP-1) production. In PBMC and FLS + PBMC co-cultures, neutralizing antibodies to IRs were added. Only anti-LAG-3 antibodies significantly increased MCP-1 secretion. The addition of agonistic LAG-3 antibody resulted in decreased effector cytokine secretion. Conclusions This is the first report comparing the effects of different IRs in o-JIA and suggests that LAG-3 might contribute to the pathogenesis of this disease. Impact",
