Sexually dimorphic placental antibody transfer during SARS-CoV-2 infection

In a paper recently published in the journal Science Translational Medicine by Bordt et al. (October 19th, 2021), maternal SARS-CoV-2 infections are studied with particular regard to maternal-fetal antibody transfer and virus-induced placental interferon responses, finding a sexually dimorphic response that results in lesser antibody transfer to the male fetus.
