title: Persistence of an encephalitogenic T cell clone in the spinal cord during chronic, relapsing experimental autoimmune encephalomyelitis.
abstract: The CDR3 region of the TCR beta-chain of a CD4+, Th1, Vbeta2+ encephalitogenic T cell clone was used as an idiotypic marker to track the location of the clone in vivo. cDNA prepared from the spinal cord, thymus, lymph nodes, spleen, and liver of the recipients at various stages of EAE was amplified using Vbeta2 and Cbeta-region primers, and the products immobilized. The membrane was probed with a 32P-labeled oligonucleotide complementary to the CDR3 region of the T cell clone. The probe reacted strongly with products from the spinal cord, spleen and liver and less strongly with products from lymph nodes and thymus of mice with acute EAE. The signal was greatly diminished in the spinal cord and other tissues during recovery from acute disease and reappeared in the spinal cord at each relapse.
