CHAPTER 9: T-CELL RECEPTOR I. EARLY STUDIES OF THE T-CELL RECEPTOR A. Classic experiments demonstrated to self-MHC restriction of the T-cell receptor B. T-cell receptors were isolated by using clonotypic antibodies C. The TCR β-chain gene was cloned by use of subtractive hybridization II. αβ AND γδ T-CELL RECEPTORS III. ORGANIZATION AND REARRANGEMENT OF TCR GENES A. TCR variable-region genes rearrange in a manner similar to antibody genes B. Mechanism of TCR DNA rearrangements C. Allelic exclusion of TCR genes D. Rearranged TCR genes are assembled from V, J, and D
