Mechanism

Thought to act on immune cells in bronchial tissue via JAK/STAT signaling, balancing cytokine output, boosting macrophage activity while curbing IL-6 and TNF-α, and supporting T-cell regulation and epithelial barrier integrity.

Safety file

Marketed as side-effect-free, but rigorous human trial data is absent; preclinical tolerability appears good.

  • Injection site reactions
  • Temporary immune system fluctuations
  • Mild respiratory sensitivity
