title: Cytokine mRNA levels in isolated feline monocytes.
abstract: Real-time PCR systems were developed to quantitate cytokine expression in short-time cultivated feline monocytes. Feline-specific interleukin-1beta (IL-1beta), IL-6, and tumor necrosis factor-alpha (TNF-alpha) primers as well as TaqMan probes were designed and were adapted to a quantitative PCR system which had been previously established for feline IL-10 and IL-12 p40. Quantitative analysis of cytokine messenger RNA (mRNA) transcription based on the comparison of the cytokine with the housekeeping gene feline glyceraldehyde-3-phosphate dehydrogenase (GAPDH), providing universally expressed mRNA. GAPDH mRNA was readily detectable in cDNA prepared from short-time cultivated peripheral blood monocytes. Cytokine mRNA was demonstrated in all samples at variable amounts. IL-1beta and TNF-alpha mRNA was constitutively expressed whereas IL-6, IL-10 and IL-12 p40 mRNA was generally expressed at a lower level and was occasionally not detected. There was a great variability of cytokine production between individual cats and at different time points in the same cat.
