  1. chronic antigen exposure increases frequency of productive TRA clonotypes in humans.

    “Moreover, our data provide evidence of chronic antigen exposure further increasing the frequency of productive TRA sequences.”

  1. T cell maturation stage increases frequency of productive TRA clonotypes in humans.

    “The frequency of productive TRA clonotypes increased along the T cell maturation stage and showed a consistent positive correlation with the donor age.”
