Abstract
Glucocorticoid hormones (GCH) are anti-inflammatory and immunosuppressive agents that inhibit T-cell growth and activation. Since the T-cell receptor (TCR)/CD3 complex mediates T-lymphocyte activation, we studied the effect of in vitro dexamethasone (DEX), a synthetic GCH, on TCR/CD3 expression.
DEX-treatment of a hybridoma T-cell line and normal un-transformed T-cell clones induced a decrease of the TCR/CD3 membrane expression after 4 days. After 4 weeks, TCR/CD3 was undetectable. However, the amount of mRNAs coding TCR/CD3 chains, including TCRα, TCRβ, CD3γ, CD3δ and CD3ε, as well as the amount of CD3ε protein, a major component of the complex, were unaltered. By contrast, a decrease of the mRNAs deriving from the TCRζ gene locus, as well as of the TCRζ protein which is responsible for the membrane expression of the TCR/CD3 complex, was induced.
These data suggest that the down-modulation of TCR expression is due to the diminution of TCRζ gene products in DEX-treated cells. (Mol Cell Biochem 167: 135-144, 1997)
