“…In order to provide a meaningful comparison between different individuals or samples, we calculated the relative amounts of the PCR products of these molecules to the amounts of the PCR products of CD3␦ (for the standardization of T cell mRNA) or the PCR products of -actin (for the standardization of total cellular mRNA) in each sample, as previously described (22,23,35,36). The CD3␦ PCR product levels were used for T cell-specific molecules, such as IL-2, IL-5, IL-12, and IFN␥, while the -actin PCR product levels were used for T cell-nonspecific molecules, such as IL-4, IL-6, IL-10, IL-17, and chemokines, which were produced by a variety of cell types.…”
