The JAK-STAT pathway is important for the production of lamellocytes following parasitoid infection (Sorrentino et al., 2004; Yang et al., 2015), and ectopic pathway activity leads to tumorigenesis as characterized by the precocious accumulation of lamellocytes (Ekas et al., 2010; Harrison et al., 1995). This evidence concerns the gene SOAT1 and infection.
