Transcription profiling of human CD4 regulatory T cells that express either CD45RA or CD45RO

ABSTRACT: CD4 T cells taken from 6 donors were sorted into CD25hi CD45RA+ (na�ve Treg), CD25hi CD45RO+ (memory Treg), CD25- CD45RA+ (na�ve responder) and CD25- CD45RO+ (memory responder) populations.

RNA was extracted (Ambion RNAqueous), amplified (SMART), labelled with cy3, mixed with cy5 labelled human reference (Stratagene), and hybridised to slides printed with Human AROS v4.0 oligonucleotides (Operon).

Slides were scanned using a Perkin Elmer GX plus, and the data then normalised with GEPAS v4.0 and collated. One sample was deemed to be of too low hybridisation quality, and was hence removed at this point.

Final data analysis was carried out using TMEV 4.0. SAM was performed using a 10% FDR. HCL and PCA were plotted from this list, and interrogation carried out using DAVID to determine pathway enrichment
