Furthermore, these cells displayed enhanced cytokine production, including IFN-\u03b3 (Interferon-gamma, a pro-inflammatory signaling molecule), TNF-\u03b1 (Tumor Necrosis Factor-alpha, a cytokine regulating inflammation), and IL-17 (Interleukin-17, a cytokine involved in immune response modulation), in patients with EOLP. And our clinical cohort of 1-year follow-up was also supported the above results in RNA level and protein level.
