Transcription of ULBP2 and ULBP3 in B cells from NHL patients. Total RNA from B cells purified from PB (A-B) or BM or LNs (C) was reverse transcribed and amplified by PCR with specific primers for ULBPs compared to GAPDH. (A-C) ULBP2 and ULBP3 mRNA expression in purified PB B cells from (A) MT or MZ (1 representative case of 4 studied) or FL lymphomas (2 representative cases of 15 analyzed) or DLCL (1 representative case of 4), (B) B-CLL (4 representative cases of 10), and (C) BM- or LN-derived B cells from 2 FL lymphomas and one DLCL.
