Could T-cell forgetfulness be induced? Maybe the clock can be rolled back so a more infantile immune system is in operation. If the T-cells keep encountering the brain, it wouldn't help, since they would relearn, but that's where CCSVI treatment (or tysabri) comes in to strengthen the blood-brain barrier and keep the T-cells out.The strength of an individual's immune system depends on the formation of "memory T cells," according to the Cornell team. These T cells remember pathogens they have previously encountered so that the next time they enter the body, they can respond to them quickly and effectively.
Adults create a large number of memory T cells during infection. Approximately 10% of these settle in a "long-lived memory pool," ready to fight the next time a pathogen enters the body.
Infant T cells do not enter memory pool
The researchers found that infant immune systems created T cells that responded to infection faster and stronger, but these cells were short-lived and did not make it into the memory.
However, the results of the team's study revealed that the same process does not happen in an infant's immune system.
When stimulating adult and infant immune systems with the same infection, the researchers found that the infant immune system created T cells that responded faster and with more strength, but these cells were short-lived and did not make it into the memory pool.
