🔓 How Immune
#CheckpointInhibitors Work
Active cancer immunotherapy activates both cell-mediated and humoral immunity.
🛑 Normally, CTLA-4 helps prevent autoimmunity by turning off T cells.
But in cancer:
➡️ CTLA-4 inhibitors block this brake
➡️ T cells stay activated
➡️ Immune system keeps attacking cancer cells
Controlled autoimmunity, unleashed on the tumor.
