Some CD4+ T cells become memory cells after encountering a pathogen and becoming activated. Memory cells help the body recognize and respond more quickly in future encounters with the same invader.

T cells are the immune system’s frontline fighters. When they detect danger, they rapidly multiply and transform into effector cells that destroy pathogens.

“After encountering a pathogen, T cells decide early whether to form a memory, or alternatively, to become an effector cell, which has potent cell-killing abilities but is short-lived. ...

Every person has 10 million to 100 million unique T cells that have a critical job in the immune system: patrolling the body for invading pathogens or cancerous cells to eliminate.
