Extending the life of immune cells – Sciences et Avenir

This article is taken from the monthly journal Sciences et Avenir – La Recherche #909 of November 2022.

Some cells increase their lifespan through an unprecedented process, according to a study from University College London (UK). In principle, with each cell division, the telomeres at the ends of the chromosomes shorten until the cell dies. But memory T cells have a parade.

Extension from other cells

Researchers show that memory T cells essential for immunity can receive telomere extensions from other cells, which prolongs their lifespan and therefore our immune memory.
