AI Summary & Key Takeaways
AI InsightIt was observed that the treatment group significantly reversed the increase in the joint thickness and the increase in the number of white blood cells, especially with the increase in neutrophils when compared with control groups.As a result, genetically modified tolDCs reduced the clinical symptoms of experimental arthritis and also reversed the changes in blood parameters due to experimental arthritis in mice.

Abstract
Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that causes chronic pain and joint destruction. T cells activation has an important role in RA pathogenesis. Activation of T lymphocytes requires the co-stimulatory signals provided by antigen-presenting cells. T-cell activation without co-stimulation results in anergy. In this study, to inhibit the activation of T lymphocytes formed in the experimental arthritis, tolerogenic dendritic cells were aimed to be obtained by the genetical modification of dendritic cells with CTLA4-KDEL overexpression in endoplasmic reticulum. Then, RA created animals treated with tolDCs and the effect of treatment on blood parameters were investigated.For this purpose, mouse collagen induced arthritis model was used. The mice with arthritis were intraarticularly treated with modified tolDCs. It was observed that the treatment group significantly reversed the increase in the joint thickness and the increase in the number of white blood cells, especially with the increase in neutrophils when compared with control groups.As a result, genetically modified tolDCs reduced the clinical symptoms of experimental arthritis and also reversed the changes in blood parameters due to experimental arthritis in mice.
