pubmed:abstractText |
The presence of T cells binding F(ab')2 fragments of the idiotypic immunoglobulin was examined by immunofluorescence in peripheral blood of patients with monoclonal gammopathy. In 3 out of 11 tested patients, 1-15% idiotype-binding T cells of either CD4 or CD8 phenotype were found. In 1 patient both a CD4+ and a CD8+ idiotype-binding T-cell fraction were present. In 1 patient the idiotype-binding T cells also reacted with a mAb directed against the variable parts of the TCR alpha or beta chains, further indicating a clonal origin at the alpha/beta level. 3 patients had an expanded predominant T-cell receptor V gene usage based on the reactivity with the limited panel of TCR mAb, but these "clonal" T cells did not bind the idiotype. The study supports the existence of idiotype-specific T cells in peripheral blood of patients with monoclonal gammopathy. Such cells might have a regulatory role on the monoclonal B-cell clone and may be an important target for immunotherapy.
