　　The interplay between sexes is a prerequisite for female growth,reproductive maturation and egg pro -duction,and the basis of schistosome pathopoiesis and propagation.The tegument is in direct contact with the host environment and its surface membranes are particularly crucial for schistosome survival in the definitive host.In this study,a streptavidin:biotin affinity purification technique combined with LC:MS/MS was used to analyze putative tegument:exposed proteins in female and male adult Schistosoma j aponicum worms.In total,179 proteins were identified in females and 300 in males,including 119 proteins common to both sexes,and 60 female biased and 181 male biased proteins.Some (e.g.,serpin and CD36:like class B scavenger receptor) were involved in host:schistosome interactions,while some (e.g.,gynecophoral canal protein) were important in the in terplay between sexes.Gene Ontology analysis revealed that proteins involved in protein glycosylation and lyso -some were highly expressed in females,while proteins involved in intracellular signal transduction,regulation ofactin filament polymerization and proteasome core complex were highly expressed in males.These results might elucidate physiological differences between sexes.Our study provide new insights into schistosome grow -th and sexual maturity in the final host and permit the screening of vaccine candidates or drug targets for schist -osomiasis.
