TNFRSF1A and retinitis: In agreement with our previous finding [41], we detected not only significant amounts of TNF-a mRNA and protein within the MCMV-infected eyes of retinitis-susceptible mice with MAIDS, but also detected significant amounts of apoptosis-associated TNF receptor 1 (TNFR1), active caspase 3, and active caspase 8 [43].
