Cytotoxic T-cells (also called killer T-cells or CD8+ T-cells) are the immune system’s highly trained assassins. Their mission is simple but deadly: seek and destroy infected or cancerous cells.
🧬 How They Work
-
They patrol the body, scanning cells for “badges” (MHC molecules) that display viral or abnormal proteins.
-
If they detect an infected or mutated cell, they lock onto it.
-
Then, like silent assassins, they release toxic proteins (perforin and granzymes) that poke holes and trigger cell death (apoptosis).
⚔️ Why They’re Important
-
They stop viruses from spreading by killing infected cells early.
-
They keep the body safe from cells that may turn cancerous.
-
They provide long-term memory after infections, so the immune system reacts faster next time.
🦸 Role in the Immune Army
-
Think of Cytotoxic T-cells as ninjas or assassins, eliminating threats with precision.
-
They don’t attack blindly—they strike only the enemies flagged as dangerous.
