Tocil !!better!! 💯 🔥

IL-6 is a pleiotropic cytokine—a signaling protein that, when overproduced, drives chronic inflammation in autoimmune diseases like rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA). Tocilizumab binds with high affinity to both soluble and membrane-bound IL-6 receptors, blocking the downstream activation of the JAK-STAT pathway. In simpler terms: tocilizumab pulls the fire alarm before the inflammatory building burns down.
