Thus for PBL, we only had adequate CD19- PC cell numbers to calculate pSTAT1 fold change for n=4 for IgA+ in HD, n=5 for IgG+ in HD, n=5 for IgA+ in SLE, and n=5 for IgG+ in SLE whereas pSTAT1 fold change was calculated for all n=6 SLE and n=6 HD in the BM samples. The gene discussed is CD79A; the disease is Huntington disease.
