A synthetic peptide homologous to retroviral envelope protein down-regulates TNF-alpha and IFN-gamma mRNA expression.

Journal Article

We investigated the influence of CKS-17, a synthetic heptadecapeptide that corresponds to a highly conserved domain of the immunosuppressive retroviral envelope protein p15E, on staphylococcal enterotoxin B (SEB)-induced TNF-alpha gene expression in human peripheral blood mononuclear cells and highly purified human monocyte preparations, as well as the production of TNF-alpha protein, using human peripheral blood mononuclear cells. RNA hybridization studies show that CKS-17 inhibits SEB-induced TNF-alpha mRNA accumulation in human peripheral blood mononuclear cells and human monocytes. CKS-17 is also shown to be highly suppressive for SEB-induced production of TNF-alpha proteins. Similarly, CKS-17 inhibits expression of SEB-induced IFN-gamma mRNA in human peripheral blood mononuclear cells. These results suggest that CKS-17 down-regulates both TNF-alpha and IFN-gamma production at mRNA level.
