In this case, cDC2 were co-cultivated with UV-treated MARC-145 cells (without infection) that had a proportion of apoptotic and necrotic cells (13.5 ± 2.6% of Annexin V+PI– and 39.4 ± 1.4% of Annexin V+PI+) comparable to that of infected MARC-145 cells (63.4 ± 3.1% of PRRSV1 N+; 14.9 ± 1.5% of Annexin V+PI– and 33.8 ± 2.6% of Annexin V+PI+). The gene discussed is ANXA5; the disease is infection.
