| Abstract |
T cells that infiltrate the synovial lesions of rheumatoid arthritis may play a key role in its pathogenesis. To learn more about their functional nature, we determined the frequency of synovial T cells that harbored the TNF alpha and Fas ligand transcript by a technique, called Fluorescence In-Cell Labeling Polymerase Chain Reaction (FICL-PCR). The mRNA of interest was detected in fixed cells by the incorporation during PCR of a fluorescein-12-dUTP label following an initial reverse transcription PCR step. Using this technique the CD3 transcript was detected in the T leukemic cell line, MOLT-4, with calculated sensitivity and specificity values of 91% and 100%, respectively. The percentage mean (+/-S.D.) of TNF alpha mRNA positive cells and Fas ligand mRNA positive cells in peripheral blood mononuclear cells from 12 rheumatoid arthritis patients were 5.1+/-2.3% and 4.8+/-3.1%, respectively. The percentage mean (+/-S.D.) of TNF alpha mRNA positive cells and Fas ligand mRNA positive cells among synovial mononuclear cells from six rheumatoid arthritis patients was 16.8+/-8.3% and 10.8+/-1.8%, respectively. This result indicates that the cytotoxic T cells expressing TNF alpha accumulate in rheumatoid arthritic lesions where they may play a pathogenic role. |
