T cells go through different stages, depending on the number of times they have been in contact with the antigen. In the first place, naïve T-lymphocytes are those cells that have not yet encountered an antigen in the thymus. Then, T-lymphocytes become memory T cells. This type of T cells are those that have been in contact with the antigen at least once but have returned subsequentl…
