In the present study, we investigated the presence of hemagglutinins on placental cells and their relationship to circulating antibodies in mice immunized against sheep erythrocytes before mating. The results obtained demonstrated that placental cells may fix large quantities of maternal immunoglobulins. The hemagglutinins are probably fixed on placental cells by the Fc, since the combining sites of the antibody were free and able to react with the antigen in the \u00ab rosette \u00bb test. It was also demonstrated that placental tissue may fix up to 1\/4 of the maternal circulating antibodies, while only 1\/200 of them were transmitted to the fetuses. Some theoretical implications of the presence in the placenta of antibodies not directed against feto-placental antigens are also discussed.<\/jats:p>","DOI":"10.1177\/030089168006600101","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T12:17:58Z","timestamp":1523881078000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Non-Specifically Bound Immunoglobulins on Mouse Placental Cells"],"prefix":"10.1177","volume":"66","author":[{"given":"Luciano","family":"Bellelli","sequence":"first","affiliation":[{"name":"Laboratory of Physiopathology, Regina Elena Institute for Cancer Research, Roma"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Luisa","family":"Sezzi","sequence":"additional","affiliation":[{"name":"Laboratory of Physiopathology, Regina Elena Institute for Cancer Research, Roma"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1980,2,1]]},"reference":[{"key":"bibr1-030089168006600101","first-page":"2077","volume":"34","author":"Alexander P.","year":"1974","journal-title":"Cancer Res."},{"key":"bibr2-030089168006600101","doi-asserted-by":"publisher","DOI":"10.1159\/000225354"},{"key":"bibr3-030089168006600101","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-230X(08)60053-6"},{"key":"bibr4-030089168006600101","doi-asserted-by":"publisher","DOI":"10.1038\/255412a0"},{"key":"bibr5-030089168006600101","doi-asserted-by":"publisher","DOI":"10.1172\/JCI107844"},{"key":"bibr6-030089168006600101","first-page":"47","volume":"21","author":"Faulk W.P.","year":"1974","journal-title":"II.
