Quantitation of cytokine production is a valuable adjunct to
standard immunologic assays in defining several pathologic processes. Nevertheless, there is little agreement about which tissues should be
assayed, which type of assay should be performed, and which stimulation
protocol should be used. As these types of assays enter the clinical
arena, there is need for standardization. There is also a need to
maximize the amount of information which may be derived from a single
sample. We compared secreted interleukin 4 (IL-4), IL-2, IL-6, tumor
necrosis factor alpha (TNF-

), and gamma interferon proteins as
measured by enzyme-linked immunosorbent assay with intracellular
cytokine production (IL-2 and gamma interferon) as detected by flow
cytometry and quantitative competitive PCR for IL-2, IL-4, TNF-
, and
gamma interferon mRNA and cDNA. Results from unstimulated cells and
cells stimulated with phorbol myristate acetate, phytohemagglutinin,
and phorbol myristate acetate plus phytohemagglutin were compared. All
three methodologies detected significant stimulation of cytokine
production. The combination of phytohemagglutinin and phorbol myristate
acetate was overall the most-potent stimulus.
