Transcription of the tumor necrosis factor alpha gene is rapidly induced by anti-immunoglobulin and blocked by cyclosporin A and FK506 in human B cells.
The human tumor necrosis factor alpha (TNF-alpha) gene encodes a cytokine whose activities have been implicated in many immunopathological processes, including the activation and differentiation of lymphocytes. Originally identified as a monocyte factor, our studies and those of others have demonstr...

Goldfeld, A E Flemington, E K Boussiotis, V A Theodos, C M Titus, R G Strominger, J L Speck, S H Proc Natl Acad Sci U S A Research Article The human tumor necrosis factor alpha (TNF-alpha) gene encodes a cytokine whose activities have been implicated in many immunopathological processes, including the activation and differentiation of lymphocytes. Originally identified as a monocyte factor, our studies and those of others have demonstrated that B and T lymphocytes produce TNF-alpha when stimulated by a variety of inducers. We report here that TNF-alpha gene transcription is rapidly and highly induced in three independently derived human Burkitt lymphoma cell lines, as well as in freshly isolated human splenic B cells, activated by antibodies to surface immunoglobulin. This burst in TNF-alpha gene transcription is associated with an induction of TNF-alpha bioactivity in the culture supernatants from stimulated splenic B cells. Moreover, induction of TNF-alpha gene transcription by anti-immunoglobulin was blocked by the immunosuppressants cyclosporin A and FK506. These studies demonstrate that TNF-alpha production is an early event in B-cell activation and they establish the efficacy of using immunosuppressants as probes in dissecting transcriptional activation pathways in human B cells. 1992-12-15 /pmc/articles/PMC50726/ /pubmed/1281550 Text en |

The human tumor necrosis factor alpha (TNF-alpha) gene encodes a cytokine whose activities have been implicated in many immunopathological processes, including the activation and differentiation of lymphocytes.
