New findings could lead to vaccine for severe malaria

... have shown. They therefore collected and analysed placentas on site in Uganda. "Most of the parasites we studied could bind to three different receptors in the placenta," she says. "This would mean that a future vaccine cannot be based on the principle of one protein-one receptor, as was previously believed....

Key to early diagnosis of autism may be in the placenta

Study uncovers placental microtransfusions lead to transmission of AIDS virus during childbirth

...iny amounts of virus-laden blood leak from women's placentas to babies during labor. All of the subjects and their babies had been given single-dose anti-retroviral drugs to minimize HIV transmission. "This work shows strongly for the first time that what we call placental microtransfusions during birth are r...

Infants with Rare Genetic Disease Saved By Cord Blood Stem Cells

Finally, cord blood cells are less mature than adult bone marrow cells and thus do not need to perfectly match the pat...
