Increased Abundance of Cytotoxic T Cells in Synovial Fluid of a Dog With Erosive Immune‐Mediated Polyarthritis

Key Points

The research aims to explore the role of cytotoxic T cells in canine erosive immune-mediated polyarthritis (IMPA).
Observation of T cell abundance in synovial fluid from a dog diagnosed with erosive IMPA.
Treatment with mycophenolate mofetil to assess its effects on leukocyte count and dog's activity.
Cytotoxic T cell levels increased in the synovial fluid compared to monocytes and B cells.
Mycophenolate mofetil reduced leukocyte counts in the synovial fluid and improved activity, though bone erosion progressed slowly.

Abstract

cytotoxic T cells-while monocyte and B cell counts remained comparable. Treatment with mycophenolate mofetil reduced leukocytes in the synovial fluid and improved the dog's activity, although bone erosion slowly progressed. Based on these findings, we propose that T cells, especially cytotoxic T cells, in synovial fluid contribute to inflammation in canine erosive IMPA and may be a therapeutic target.
