Abstract From the Canadian patent

The present invention relates to a method for measuring de novo T-cell production in humans and more, particularly to the assessement recent thymic emigrant (RTE) diversity in a T-cell sub-population of a patient by the detection of T-cell receptor .beta. chain DNA deletion circles (TCR.beta.DC) generated during TCR gene rearrangement of thymocytes in the thymus. The method comprises isolating a T-cell sub-population from a patient, extracting genomic DNA from the T-cell sub-population, amplifying the genomic DNA with a primer specific for a T-cell receptor .beta. chain DNA rearrangement deletion circle (TCR.beta.DC) family and detecting the TCR.beta.DC, the TRC.beta.DC being indicative of …
