In the paper, two inaccuracies have been found.

The first inaccuracy is in Section 2.2 on page 3 (in the pdf) in the following sentence: “These are classical MHC I that induce inflammation and their expression of immune rejection might lead to recognition by cytotoxic T lymphocytes and immune rejection.”

It should be without “of immune rejection.”

The second inaccuracy is in Section on page 7 in the following sentence: “These lymphocytes are thought to protect the pregnancy against external antigens and to support trophoblast growth by secreting IL-8, which promotes trophoblast invasion.”

It is not “external antigens” but “pathogens.”

We apologize for this oversight and for any confusion that it has caused.
