CXCR5 and angioimmunoblastic T-cell lymphoma: We had access to paired blood-liver samples from 4 AILD patients; for each, we extracted genomic DNA and performed bulk TCR-beta-seq from blood PD-1+CXCR5- mCD4 T cells, blood PD-1- mCD4 T cells, and whole liver biopsy (Supplementary Fig. 8, Supplementary Fig. 9A and supplementary Data 6 and 7).
