TRBV13-2+ TCRβ chains that were shared in the indicated number of total CD4+, CD4+Foxp3−, and CD4+Foxp3+ populations in the CNS’ and spleens of mice with EAE were transduced into TCRβ−/− HPCs to generate retrogenic mice. Sequences β1-β6 were identified in the CNS’ and spleens of multiple mice (CNS shared, public). Sequences β7-β10 were identified in the spleens of multiple mice, but in CNS tissue of only a single mouse (CNS non-shared, public). Sequence β11 was identified in the spleen and CNS of a single mouse, and sequences β12-β15 were isolated from TRBV13-2+ MOG35-55 -specific T cell hybridomas, and were not observed in any of the mice evaluated for the repertoire analyses (private). For TCRβ chains identified in a single mouse, the percent of total TRBV13-2+ TCR sequences in the CNS bearing the indicated sequence is listed in parentheses. OTIIβ comprises the TRBV13-2+ TCRβ chain from the OTII ovalbumin 323–229-specific TCR, and was assessed as a negative control.
