AB Identification of the T-cell receptors (TCR) used by synovial cytotoxic
T lymphocytes (CTL) of patients with reactive arthritis (ReA) may be
crucial to better understanding the pathogenetic mechanism underlying
the HLA-B27 association of spondylarthropathies. The authors, therefore,
sequenced 25 TCRB chains from HLA-B27-restricted CD8+ CTL clones and two
clonal lines specific for self- or Yersinia enterocolitica antigen
isolated from synovial fluids of 3 HLA-B27+ patients with ReA and PBL of
one healthy HLA-B27+ individual. Fourteen non-HLA-B27-restricted CTL
served as controls. Both autoreactive and Y. enterocolitica specific
HLA-B27-restricted CTL used a highly limited set of VB genes with
preferential rearrangement of three closely related VB families (VB 13,
14, 17), suggesting that these families contain a preferred site for
contact with the HLA-B27 molecule. In addition, the presence of limited
TCRBJ usage, limited heterogeneity in CDR3 sequences and dominant clones
from individual donors among these CTL indicate that TCRB chain usage is
further restricted by a limited set of peptides bound to the HLA-B27
molecule. Limited TCR usage by SF CTL of ReA patients may lay a basis
for therapeutical manipulation of the T-cell response in the
spondylarthropathies.
