25781974 These results thereby demonstrate that induced expression of Syncytin-2 is highly dependent on the interaction of bZIP-containing transcription factors to a CRE/AP-1 motif and that this element is important for the regulation of Syncytin-2 expression
23177091 MFSD2a, the Syncytin-2 receptor, is important for trophoblast fusion.
21771862 Analysis of non-spliced ERVFRDE1 mRNAs and env mRNAs detected efficient splicing of endogenously expressed RNAs in trophoblastic but not in non-placental cells.
21493955 results further highlighted the existence of a correlation between the extent of the decrease in the expression levels of both syncytins 1 and 2 fusogenic proteins and the degree of severity of preeclampsia symptoms
19616006 These results highlight the importance of Syncytin-2 in BeWo and primary human trophoblast cell fusion.
18650494 expression decreased in preeclamptic placentas; may function as a second fusogenic protein for placental cell fusion
18215254 Syncytin 2 expression illustrates the abnormal trophoblast differentiation observed in placenta of fetal T21-affected pregnancies.
18077339 findings show that in both humans and mice, one of the two syncytins (human syncytin-2 and mouse syncytin-B) is immunosuppressive and, rather unexpectedly, the other (human syncytin-1 and mouse syncytin-A) is not
16714059 immunolocalized only in the villous trophoblast of the chorionic villi, at the level of cytotrophoblastic cells
16140326 The crystal structure of a central fragment of syncytin 2 "fossil" ectodomain is reported, allowing a remarkable superposition with the structures of the corresponding domains of present-day infectious retroviruses
