A recent examination related to special immune cells in the placenta conducted by research scientists at the University of Debrecen could contribute to a more profound understanding of processes and complications during pregnancy and, in the long run, even to the development of new therapeutic options. It was this group of scientists in Debrecen that were the first to provide a comprehensive genetic picture of the so-called Hofbauer cells. The findings of their international collaborative research project were published in the prestigious international journal JCI Insight.
