Experimental Protocol

Naïve (CD44lo) OT-I T cells were CFSE labelled and transferred in a model of deletional tolerance (RIP-OVAhi mice), a model of immunity (mice primed with OVA coated splenocytes and LPS) or a model of lymphopenia induced proliferation (Rag-/- mice). 60 hrs (RIP-OVAhi and OVA coated splenocytes) or 5 days (Rag-/-) after transfer, OT-I cells that had undergone two or more divisions as determined by CFSE dilution were sorted, RNA extracted and samples were prepared for hybridisation to Affymetrix microarrays. As a control for naive cells, CFSE labelled OT-I cells were injected into antigen-free B6 mice and the undivided naive cells were sorted after 60 hrs and also used for microarray analysis. Two replicates were prepared for the naive cells, cells from RIP-OVAhi mice and cells from OVA coated splenocyte primed mice, while one replicate was prepared for the cells from Rag-/- mice.
