Abstract
The helper T cell clone 3H.25 is specific for hen egg white lysozyme and the class II MHC molecule I-Ab. This TH cell has three rearrangements in the beta-chain gene family-a V beta-D beta-J beta 1 and a D beta 2-J beta 2 rearrangement on one homolog and a D beta 1-J beta 2 rearrangement on the other. These observations demonstrate that this functional T lymphocyte expresses only a single V beta gene segment and, accordingly, exhibits allelic exclusion of beta-chain gene expression. The rearranged 3H.25 V beta gene segment is the same as that expressed in a T helper cell specific for cytochrome c and an I-Ek MHC molecule. Thus, there is no simple correlation between the V beta gene segment and antigen specificity or MHC restriction.Entities:
