T-cell Vaccination

T-cell vaccination (pronunciation: tee-sell vak-si-ney-shuhn) is a type of immunotherapy that uses the body's own immune cells, specifically T-cells, to fight diseases.

Etymology

The term "T-cell" is derived from the organ where these cells mature, the thymus. The term "vaccination" comes from the Latin vaccinus, meaning "of or from the cow", as the first vaccines were developed from cowpox to immunize against smallpox.

Definition

T-cell vaccination refers to a therapeutic strategy where T-cells, a type of white blood cell, are used to stimulate an immune response. This is typically achieved by isolating T-cells from the patient, modifying them in a laboratory to target specific pathogens or cancer cells, and then reintroducing them into the patient's body.
