Memory Helper T Cells. Whenever you hear that you are immune to a disease, this is what this means. It means that you have living memory cells that remember a specific enemy. And that enemy might come back, so they stick around and become powerful guardians. Memory Cells are able to recognize a familiar enemy much quicker than the Innate Immune System ever could. In case of another infection, this makes the long trip of the Dendritic Cell to the lymph node unnecessary because these Memory Helper T Cells can immediately activate and call for heavy reinforcements.
