In #Science #Immunology, @tobiasplowman.bsky.social, Kassiotis, & al report canonical #IL13RA1 expression is negatively regulated by E2 #estrogen & also describe a primate-specific RTE-derived IL-13Rα1 isoform that antagonizes the canonical receptor & attenuates responsiveness to #IL4 and #IL13!

Primate retroelement exonization and sexually dimorphic IL13RA1 transcription tune type 2 immune responses
Co-option of primate-specific retroelements creates an alternative IL-13Rα1 subunit that tunes type 2 immune responses.
