Choi et al. (2016), investigated the effect of the pathological activation of maternal IL-17A pathways on fetal development by pre-treating pregnant mothers with IL-17A blocking antibodies before injecting them with poly(I:C) and examining cortical development in the fetus. They reported disorganized cortical phenotypes in offspring following in utero MIA and autism-like behavioral abnormalities in offspring (Choi et al., 2016). Here, IL17A is linked to autism.
