pubmed-article:3264808 | pubmed:abstractText | Triggering of the T-cell receptor by anti-CD3 monoclonal antibodies (mAb), for example OKT3, induces accessory cell (AC)-dependent interleukin-2 (IL-2) and IL-2 receptor synthesis, and ultimately, T-cell proliferation. We report on the ability of a HLA-class I specific monomorphic mAb, namely FMC16, to inhibit OKT3-driven T-cell mitogenesis. FMC16 was apparently selective for OKT3 because it did not block Concanavalin A (Con A) or mAb Leu-4 induced proliferation. Moreover, this effect was not due to non-specific toxicity nor interference with OKT3 binding. Kinetic analysis showed that FMC16 was inhibitory when added up to 24 hr after initiation of culture. FMC16 drastically reduced both IL-2 production and IL-2 receptor expression, but did not interfere with IL-2 responsiveness. The inhibitory effects were not altered by the addition of exogenous IL-2 if FMC16 was present at the beginning of culture; however, IL-2 did restore proliferation if FMC16 was not added until 3 to 6 hr after initiation of culture. This coincided exactly with an IL-2 mediated increase in the level of TAC-positive cells. Furthermore, T-cell activation triggered by the synergistic action of OKT3 and a phorbol ester (TPA) in the absence of AC was also blocked by FMC16, suggesting that inhibition was not AC-dependent. Taken together, these results indicate that FMC16 interferes with early signals leading to IL-2 production and IL-2 receptor expression and suggest that HLA-class I determinants play an early role in T-cell activation. | lld:pubmed |
