Importantly, infection of iMGs from both iPSC lines (iMG #1 and iMG #2) with Lai/YU-2env resulted in an MOI-dependent increase in p24Gag secretion (Fig 3C; left panel) and IL-1β secretion (Fig 3C; right panel) at day 3 pi, which was suppressed upon EFV treatment. The gene discussed is IL1B; the disease is infection.
