To identify TCR clonotypes in HTLV-1 Tax11-19–specific CD8+ T cells, we examined and compared TCR repertoires in HAM/TSP PBMCs, in enriched CD8+ T cells, and sorted Tax11-19–specific CD8+ T cells from 7 HLA-A*0201+ HAM/TSP patients. The gene discussed is HLA-A; the disease is tropical spastic paraparesis.
