Interleukin-4 Potentiates Peripheral Deletion of Autoreactive Th1 Cells in Proteoglycan-Induced Arthritis

Dr. Zhang is studying the mechanism of treating RA with a cytokine called Interleukin-4, which is thought to retard the disease development by inducing apoptosis (death) in harmful T lymphocytes (malfunctioning by attacking self tissues). In normal healthy individuals, the harmful T lymphocytes would be removed by apoptosis, but they remain in RA patients.
