Bovine blood gamma/delta T cell stimulation study

Blood gamma/delta T cells were purfiied from holstein calves less than six months old. Blood from 4 individual calves were pooled and gamma/delta T cells were purified by immunomagnetic separation, rested in RPMI medium for 12h, and underwent ConA & hIL-2 stimulation. Total RNAs were extracted by using Trizol reagents. 15 ug of total RNA was used for cDNA synthesis and microarray hybridization. Table 1: regulated genes These genes were identified, in GeneSpring software, via filtering of genes with relative expression ratio of 1.5 and over or 0.667 or below, equivalent to up- and down-regulation by fold change 1.5 or more, in both experiments. Table 2: down-regulated genes These genes were identified, in GeneSpring software, via filtering of genes with relative expression ratio of 0.667 or below, equivalent to down-regulation by fold change 1.5 or more, in both experiments. The avergae fold change was then converted to negative value. Gene annotation was performed by using GeneSpring's "Build Simplified Ontology" constructor. Table 3: up-regulated genes These genes were identified, in GeneSpring software, via filtering of genes with relative expression ratio of 1.5 or over, equivalent to up-regulation by fold change 1.5 or more, in both samples. Gene annotation was performed by using GeneSpring's "Build Simplified Ontology" constructor. Keywords: other
