Where this comes from

Abstract

Six out of 12 Sézary patients shared one clonotype (TRAV13-1*01-TRAJ49*01-TRBV20-1*01-TRBJ2-3*01). TRBV20-1*01 (also known as Vb2) that binds toxic shock syndrome toxin-1 was utilized by Sézary cells among half of the cohort, which would be expected for a common unifying origin.
