Abstrakt: The present study was undertaken to assess the presence of tumor necrosis factor (TNF)-alpha mRNA and protein in circulating human blood monocytes and to study the TNF-alpha gene expression in human monocytes isolated by continuous Percoll gradient fractionation. The technique of RNA isolation directly from the blood samples was used to study TNF-alpha mRNA expression in circulating human blood leukocytes. It was shown that human blood leukocytes of healthy donors contained no presynthesized pool of TNF-alpha mRNA as well as no TNF-alpha protein. It was found that early pretreatment with cycloheximide interferes with TNF-alpha mRNA induction by Staphylococcus aureus.
