Abstract
Ten Lewis rat T cell lines responsive to Torpedo californica acetylcholine receptor (AChR) were assayed for TCR V beta usage. All lines were CD4+, OX-22-, and exhibited reactivity to one or more AChR chains. Several different V beta s were expressed by these lines, but V beta 15 was dominant in 5 of 10 lines. Unique CDR3 sequences were observed among the 10 lines, although three of the V beta 15 rearrangements used J beta 1.4. These data suggest that V beta 15+ T cells are selected in the in vitro response to the antigenically complex AChR in the Lewis rat.
