In one example, the present invention comprises a deliberate insult or the recognition that an insult has occurred in a patient, which insult induces an immune recognition event. The T cell repertoire is catalogued from samples of the patients lymphocytes from before and after the insult in order to detect and sequence the TCR alpha and beta loci of highly expanded T cell clonotypes. In some examples, this information is used in turn to generate autologous T cells or to create autologous genetically-engineered T cells, either of which include TCR sequences that target the individuals disease or injury, resulting in cure or amelioration of symptoms.
