As shown in Fig. 3A and 3B, TRAIL decoy receptor, DcR1 and DcR2 expression in MDM cells infected with HIV-1 PV were significantly down-regulated on the 7th day post infection compared with mock-infected control (n = 12; p = 0.0281 for DcR1, p = 0.0475 for DcR2). The gene discussed is TNFRSF10D; the disease is infection.
