The pro-survival BAFF receptors Transmembrane activator and CAML interactor (TACI, CD267) as well as transcription factors bcl-2 and bcl-xl were expressed more strongly in memory CD27+ relative to naïve CD27− B-cells but did not differ between HD and CIR (data not shown). This evidence concerns the gene TNFRSF13B and Huntington disease.
