Ichnovirus manipulation of plant responses to herbivory leads to benefits for their parasitoid partners in terms of reduced developmental time within the parasitized caterpillar. Interestingly, plant-mediated ichnovirus-induced effects also enhance the performances of unparasitized herbivores which in natural conditions may feed alongside parasitized ones. We discuss these findings in the context of ecological costs imposed to the plant by the viral symbiont of the parasitoid. Our results provide intriguing novel findings about the role played by carnivore-associated symbionts on plant-insect-parasitoid systems and underline the importance of placing mutualistic associations in an ecological perspective.After birth, the alveolar epithelium is exposed to environmental pathogens and high O2 tensions. The alveolar type II cells may protect this epithelium through surfactant production. Surfactant protein, SP-A, an immune modulator, is developmentally upregulated in fetal lung with surfactant phospholipid synthesis. Herein, we observed that the redox-regulated transcription factor, NRF2, and co-regulated C/EBPβ and PPARγ, were markedly induced during cAMP-mediated differentiation of cultured human fetal lung (HFL) epithelial cells. This occurred with enhanced expression of immune modulators, SP-A, TDO2, AhR, and NQO1. Like SP-A, cAMP induction of NRF2 was prevented when cells were exposed to hypoxia. NRF2 knockdown inhibited induction of C/EBPβ, PPARγ, and immune modulators. Binding of endogenous NRF2 to promoters of SP-A and other immune modulator genes increased during HFL cell differentiation. In mouse fetal lung (MFL), a developmental increase in Nrf2, SP-A, Tdo2, Ahr, and Nqo1 and decrease in Keap1 occurred from 14.5 to 18.5 dpc. Developmental induction of Nrf2 in MFL was associ
