Representative TCR-Vβ spectratypes from nonresponders and responders before and after ATG-based treatment.

Overrepresented CDR3 lengths on spectratype analysis persist in nonresponders to immunosuppression, but become less dominant in responders. The length in base pairs of the dominant peak is indicated on the x-axis. The y-axis represents relative fluorescence intensity. The percentages with each spectratype give the percentage of the total T-cell repertoire made up by the indicated TCR Vβ family. (A) Two representative nonresponders, and (B) the 4 responders.
